StreamFab FAQ

[KidJoe]

I thought about this over the past few months as I saw repeated questions. A thread this week, convinced me to sit and type this up. Hopefully some find it helpful.

Mod's, feel free to remove this if you don't feel its appropriate. You are also welcome to edit, correct, change, revise, reformat, this is you see fit.

And just to be clear to everyone, I have no relation to DVDFab other than I purchase and use their products. I do NOT speak on their behalf or otherwise represent them. The info I am presenting is based on my usage of DVDFab Downloader, now StreamFab, posts in the forums, and general knowledge.

NOTE: This first post is a little old and some of the information may be out of date, but it is mostly relevant.


FAQ

Does StreamFab screen record or download?
StreamFab downloads the audio and video files from the supported streaming services. It does not screen record or capture the movie during playback.


Is there a limit on how much I can download? If so, why?
Yes, there is a limit. It varies by streaming service, but generally 50 to 100 downloads per streaming service, per day, per FAB account. For more details see -> https://forum.dvdfab.cn/forum/softwa...n-on-downloads

NOTE: the PER FAB Account is important if you have a multi computer license on your FAB account. If you sign into StreamFab using the same FAB account on multiple PC's, the daily limit is spread across them. In other words, if the Amazon limit is 100 per day, logging into two computers with the same Fab account will not get you 200 per day.


The StreamFab website says 1080p and 5.1, I’m not getting that. Why?
StreamFab and other downloaders use a browser-based method to connect to the streaming services..

Due to the different DRM methods employed by the various streaming services, there may be limits on the maximum resolution video or audio available to a web browser for playback or if using a browser-based tool like StreamFab.

These limits will vary from service to service, hence the limit of 720p on some services like Disney+, Hulu, Apple TV+, etc. when using a web browser, Streamfab and some other similar tools, including stream recorders.

For a list of maximum resolution and audio StreamFab supports for each streaming service, see the first post of -> https://forum.dvdfab.cn/forum/softwa...-here-~updated


StreamFab is supposed to be able to download at 1080p or 720p from this streaming service, why is this movie such a low resolution?
While StreamFab is capable of downloading up to 1080p from services like Amazon and Netflix, and 720p from others, we’ve seen a few movies and shows which only download at 480p and 576p even though they appear to be available to stream at 1080p/720p using the service’s app on a device like Roku/FireTv/GoogleTV.

Looking further at this, the streaming service just doesn’t have a higher resolution version of the movie/show available to download via StreamFab or other similar tools. While I’ve seen this reported mostly about Amazon and Netflix, it's possible you might experience this on other services a well.

Example: For Netflix, Sony and Sony Studios like Columbia limit their movies to 540p and 480p. So while you can download other titles from Netflix at 1080p, for Sony movies you're stuck at 540p maximum.


What resolution video and audio will StreamFab download? Do I have control over that?
On the VIP Service Settings in StreamFab there are various options to determine the file format (MP4 vs MKV), Video Codec (H264 or H265), Audio Codec (EAC3/AC3 or AC3), Video Resolution (1080p or 720p), as well as the ability to download 4K HDR video from HBOMax on select titles.

Based on how those options are set, when StreamFab goes to download a movie or show, it checks what the streaming service has available for that title, and downloads a copy that best matches the options you have set. If a version that matches your settings isn’t available, StreamFab will download the next best version of that title.


How can I tell the details of the movie or show I’ve downloaded? In particular the bit rates, codec, etc.
I use a tool called MediaInfo It can show you a basic text view, but also a more detailed view. (I like View -> Basic or View -> Text View)

Is StreamFab lossy?
All streaming providers use compression so they use less data as they stream, which can help reduce buffering, accommodate for internet congestion, etc. This is lossy. But StreamFab downloads them from the Streaming services without changes. It doesn’t recompress, etc.

In other words, the movie/show exists in the streaming service in a lossy format, but StreamFab itself is not introducing any further loss.


Does StreamFab alter or re-encode the movie it downloads in any way?
No. StreamFab downloads the movie as it is presented by the streaming service. It does not re-encode it, change the bit rates or other audio or video parameters, etc.

NOTE: Due to DRM changes on the Streaming Service sites occasionally StreamFab has implemented a necessary workaround that does involve re-encoding after download for some, but not all, movies and shows. In such a case you will get a pop-up message alerting you to the necessary re-encode. Once FAB fixes its DRM routines, they remove the re-encode workaround.


You said StreamFab doesn’t alter the download, so what happens during the Processing or Remuxing stage?
I don't know the technicals of how StreamFab works, but... Per Wilson.Wang DVDFab Staff “Because of that the video and audio are stored separately on the server of streaming services, and they are encrypted (this is why StreamFab need take 3~5 mins to process the video and then remux the video).” https://forum.dvdfab.cn/forum/softwa...966#post399966


How can I be sure that the files aren’t being re-encoded by StreamFab?
On Windows, open Task Manager and go to the Performance tab. Watch CPU and GPU usage. If re-encoding is taking place, you’ll see one of them spike to near 100%.

If it's just remuxing, the hard drives will show high usage, but the CPU/GPU will only show minimal usage.

If its re-encoding, you'll see high CPU or GPU usage


Will StreamFab downloads look as good as my Bluray Rips?
In short, it depends. They will at least look and sound as good as if you are streaming directly from the service, assuming you can download the same resolution that the service’s streaming app on a device like Roku/FireTV/etc supports.

In other words. StreamFab Max 1080p downloads will look as good as streaming the movie at 1080p using a Roku/FireTV/GoogleTV device to watch it. While a StreamFab Disney+ 720p download will look like Disney+ 720p streaming on a Roku, there will be differences to streaming Disney+ at 1080p on a Roku, however if you can tell the difference depends on several factors (your eyes, your TV, internet connection, etc).

The long answer is that it depends on how you rip your discs, if you compress while you rip, and what or how much compression you use. If you use no or little compression when you rip your disc, the disc rip will look better. If you use a lot of compression, or adjust the resolution when you rip, they might look the same.

See also the next question/answer.


Why are my downloads smaller than what I get when I rip the movie off a disc?
Streaming services are at the mercy of the internet. If you look they will provide recommended internet speed to watch the different resolutions.
For example, Hulu's help article says:

For a consistent, quality viewing experience, we recommend that your internet connection is capable of achieving at least the following sustained download speeds:*

3.0 Mbps for Hulu's Streaming Library
8.0 Mbps for live streams
16.0 Mbps for 4K content
*Viewers may be able to stream at a reduced video quality with 1.5 Mbps

Considering many 1080p Bluray discs can be around 40 Mb/s data rates and 4K UHD discs are 60-128 Mb/s data rates, fitting that much into a 3 Mbp/s or 16 Mbps "recommended connection speed" is obviously going to need to be compressed.

This compression from the streaming services impacts the file size and quality.


I downloaded the same movie from two different streaming services, and they are different sizes. Why?
The streaming services do not all use the same bit rates and codecs for the audio and video.

In another thread I used an example of the same Star Trek Undiscovered Country movie from Amazon Prime and Paramount+. The Prime copy had higher bit rate and better audio, and as a result also has a larger on disk size. For more, see -> https://forum.dvdfab.cn/forum/softwa...408#post403408

[KidJoe]

Is there a limit on how much I can download? If so, why?
Yes, there is a limit. 50 downloads per streaming service, per day. For more details see -> https://forum.dvdfab.cn/forum/softwa...n-on-downloads

NOTE: I do not recall the discussion on the impacts of having multiple licenses, and running StreamFab on multiple computers. Like is the limit of 50 per service per day on a per DVDFab account basis.

I can't edit the original post so...

Clarification: the limit is Per service PER DVDFab account. So if you have multiple licenses, and run it on multiple PC's, you'll be limited to 50 per service TOTAL.

Problem Reports


How do I report a problem?
There are 2 ways.
First: From the menu in StreamFab, use the Feedback option. Provide as much detail as you can. My understanding is that the Feedback Option will also capture and include your logs.

Or Second: Create a post/thread in the forum
NOTE: if a post or thread about the exact same error exists, consider replying to that thread. However you can create a new post.

• Select the version of StreamFab you’re having the problem with (if its not in the prefix drop down, type it in the title)
• Provide a clear title.
• In the body of the post include a clear description of what is happening and include
  • any error message you are seeing (exact text if possible), and such.
  • Which Streaming Service
  • What title you are trying to download, if it’s a series or episode of a series please include the Season and Episode number.
  • Is the error is reproducible or not. If reproducible then include the steps you take to get the error.
• Most importantly, attach your log files to the post.

Where are the StreamFab logs kept?
By default in Windows, they are kept in [My Documents]\DVDFab\StreamFab\log although you can use the “Open Log Folder” option off the menu in StreamFab which will take you right there. Newer versions of StreamFab allow you to move your Log, Temp and Download folders via the General Tab under the Settings menu.


Which files do I need from the log folder when posting to report a problem?
Typically the StreamFab.log file should be enough, however if you can zip and upload the entire folder that would be great.


I’m trying to attach my logs to a forum post but the forum says the file is too big. What should I do?
Try to zip the files before attaching. If they are still too big, use the FeedBack option off StreamFab’s menu.

If you can consistently reproduce the error, you can exit StreamFab, clear out the log folder, restart StreamFab and reproduce the failure, then zip the logs. See Post 11 of this thread for how to clear the temp and log folders

It does not hurt to clear the log folder from time to time.


Can I move the location of the log folder? For example, I use OneDrive or such and it constantly is trying to sync my documents, and therefore the logs
Yes, in the newer version of StreamFab, you can relocate the logs, temp and download folders. In StreamFab, use the "3 bar" (or hamburger) menu, select Settings, and look on the General tab.

Explanation of StreamFab VIP Services settings

These are found under Menu -> Settings -> VIP Services
NOTE: in some cases users have had to exit and restart StreamFab after changing these settings. So if you make a change and it didn't appear to take effect, please exit and restart StreamFab.

Amazon Region:
I am not sure about this setting as it has no noticeable effect for me.
I leave it as Auto.


HBO Europe Regin:
I am not in Europe and it has no noticeable effect for me.
I leave it set as Auto


Video Format: MP4 or MKV

MP4 and MKV are containers for the video and audio codecs to be placed in.

MKV allows using 3rd party tools later to gain options such as manually adding Chapter Marks, Flagging a Subtitle track to be always on, etc. Some mobile devices do not support MKV files.

If you know your devices support MKV files, and you might want to use 3rd party tools to add those features, then select MKV. Otherwise, select MP4.

NOTE: These are “containers.” They do NOT impact the audio or video codec stored inside.


Video Codec (Amazon & HBO): H264 or H265
Note: this setting impacts downloads from Amazon Prime and HBOMax, currently the other services will be downloaded as H264/AVC no matter this setting.

Short version, H264 (also known as AVC) and H265 (also known as HEVC) are video standards to compress digital video or live streams. They help reduce the space needed to store a video file, without losing video quality when compared to RAW video. These codecs reside INSIDE the MP4/MKV container.

You can Google “H264 vs H265” to read more

H264 is older and more widely supported. If you have older devices you’ll likely want to stick with H264. H264 gives you a smaller file than the uncompressed version.

H265 is the follow-on to H264. It is more efficient, can use a lower bit rate and can produce a smaller file than H264 yet keep the same video quality. Or you can use higher bitrates to get better video quality in the same file size as an H264 movie. Unfortunately, H265 requires more processing power, and it's supported on newer devices.

Only use H265 if you know your devices support it. HINT: If your device supports 4K/HDR then it will support H265

All of my devices support H265, so I select H265


Audio Codec: EAC3/AC3 or AAC

Dolby AC3 is a multi channel audio coding standard, and is a lossy compression.

Dolby E-AC-3 is the follow-on to AC3. It is also known as Dolby Digital Plus, DD+, E-AC-3, and EC-3. E-AC-3 supports higher bitrates than AC3 and is superior in keeping fidelity to the original audio source than AC3. It can provide better audio quality than AC3.

AAC is an audio coding standard for lossy digital audio compression, a successor to MP3 that provides higher efficiency. It is not supported by Bluray or DVDs, however it is supported and used by online streaming services. There are different types of AAC that might not be supported on portable players.

Which should you use? That is your choice, but on my home audio setup, I generally get better surround audio using EAC3, so I set it to EAC3/AC3 and skip AAC.


Video Resolution (if available): Full HD 1080p or HD 720p

1080p is up to 1920 by 1080 pixels for a 16:9 aspect ratio. Some films are 2.35:1 or such, in which case you’ll see 1920 by something… NOTE: Some services will add black bars to pad the top and bottom of the frame of 2.35:1 movies to 16:9 ratio file.

720p is up to 1280 by 720 pixels for a 16:9 aspect ratio. Because there are less pixels, the file sizes on disk will be smaller, so this is a good choice if you are looking to save space. Many broadcast TV channels like ABC, Fox and others are 720p. If you’re happy with their quality, you’ll probably be ok with 720p downloads.

I prefer the higher resolution, so I select 1080p

Some streaming services like Disney+, Apple TV+ do limit web browsers to 720p, so StreamFab can only download from them at 720p, even if Video Resolution is set to 1080p


Download HBO Max videos in 4K HDR10/Dolby Vision quality if available: check box
Select titles on HBOMax have been available in 4K. See -> https://help.hbomax.com/us/Answer/Detail/000001167

With this box checked, StreamFab will download the 4K copy of the movie or show in your queue. If its not available, it will download the copy which matches your Video Resolution setting.

Because I have 4K TV’s, I leave this selected. If I also want the 1080p copy (for my TV’s that don’t support 4K and HDR), then I go into settings, uncheck this, and download the movie again.


Download subtitle Remux into File or Extract to SRT File
When you select Remux into File, subtitles will be embedded or included in the video file (i.e. inside the MP4 or MKV container, along with the audio and video portions). If you ever copy the movie somewhere, it's one single file for everything. In this case, the subtitles are image based.

If you select to Extract to SRT file, you’ll end up with separate .SRT files for each subtitle track, plus the MP4/MKV file as your download. The SRT files will be plain text and displayed by the player as an overlay.

How you set this is a preference and a “what do your devices support” thing.

For me, my devices support internal/embedded subs, so I select Remux into File


Output folder
This is where your downloads will end up. You can change it from the default to another drive letter or folder.

Create Subfolder for each streaming website
Selecting this option will make a folder separate folders for each streaming service in your output folder. The downloads from each service will be placed in its own folders.

Not selecting this means all downloads from all services are placed directly in the Output folder.


Enable GPU Hardware Acceleration
This may no longer be used.
When first released, DVDFab Downloader (what StreamFab was called before version 4) did do some re-encoding, and GPU Hardware Acceleration, if selected, did speed that process up by utilizing supported GPUs instead of relying on CPU and software.

When unselected, StreamFab should use CPU processing power and software to re-encode if necessary

Generally speaking, since StreamFab isn’t re-encoding, this setting should not make a difference.

NOTE: Due to DRM changes on the Streaming Service sites that started on December 1, 2021, StreamFab has implemented a necessary workaround that DOES involve re-encoding after download for some, but not all, movies and shows. In such a case you will get a pop-up message alerting you to the necessary re-encode. Please see the release notes to StreamFab v5.0.0.8 and 5.0.0.9 for the published information https://www.dvdfab.cn/downloader-new.htm

[KidJoe]

I don't have the ability to edit the above posts so...

NOTE: In response to the DRM Changes from December 1, 2021 and December 7, 2021, StreamFab 5.0.1.3 was released on 12/28/2021 which includes:

Fix: A failure problem when downloading streaming videos due to the updated DRM schemes.

As such, the workaround that DOES involve re-encoding after download for some, but not all, movies and shows mentioned in notes above should NO LONGER BE NEEDED.

I downloaded super girl episode on Netflix with pretty low bitrate, only 2000kb.
Please guide me how to fix this problem.
I want to say that the video I download here is 1080p quality, but the resulting bitrate is only 2000kb

StreamFab can only download the best version the provider makes available. If a 1920x1080 2,000kb/s bit rate is the best Netflix offers, that is the best StreamFab can download. Keep in mind your internet can also factor into that, and if you're using a VPN.

I just downloaded Supergirl S03E01 Girl of Steel from Netflix (USA) as a test.

The Video drop down allows me to select 1920x1080 (Bitrate 3469 kbps). That is the best netflix has available for me to pick, so that is what StreamFab downloaded.

Per the download is
First Video Stream
3,468 kb/s 1920*1080 (16:9) at 23.976 FPS AVC

First Audio
English 640 kb/s 48.0 kHz, 6 Channels E-AC-3 (Dolby Digital Plus)

NOW, StreamFab did have the option for 1920*1080 (Bitrate 2348 kbps) so if you picked that you'd get lower.

i also tried with another program. it outputs video with bit rate higher than 5000kb

[KidJoe]

i also tried with another program. it outputs video with bit rate higher than 5000kb

It is difficult to compare StreamFab with "another program" because they could use different methods to download. This could impact the options available to download.

While I don't claim to know how StreamFab, or a competitor product that I've tried, does their thing, it is possible the "other program" might use a different method to download from the streaming providers than StreamFab does, that other method *MIGHT* allow for other streams to be downloaded, OR that other program could be a stream recorder that encodes at a higher bit rate than the source video has.

I gave you an example of what I see using StreamFab. How does it compare to StreamFab on your computer?

[KidJoe]

Delete your Temp and Log folders if you are having issues

1. If you use Microsoft Onedrive, make sure your TEMP, LOG and OUTPUT folders are not located where Onedrive is trying to back them up. If they are, move them out to another location, on a drive/folder that isn't touched by Onedrive, and has plenty of free space (I like to make sure I have at least 100gig free).
2. If you were offered "an update is available" button in StreamFab, and used it to update, and didn't use the OFFLINE installer to update SF, try using the offline installer to re-install over top of your current installation. To do so -> Make sure SF is closed, and QCEF.EXE process isn't running before trying to run the installer. Windows users can check in Windows Task Manager before trying to run the installer, OR make sure StreamFab isn't set to start when your computer starts, reboot your computer, and run the offline installer before trying to start SF.

TIP: If you don't use StreamFab's scheduler, set "What do do when close window" to EXIT PROGRAM, and make sure SF is *not* set for "Auto Start Upon System Startup" this way you know the app isn't running when I try to update it via offline installer. While the installer should kill all SF processes/tasks, I prefer to make sure they aren't running myself.

3. I would also suggest deleting your StreamFab Temp and LOG folders with SF closed and try again.

1. With SF open, use the hamburger/3bar menu in StreamFab and select Settings
2. On the General tab, make note of your TEMP and LOG directories (you will need this info later)
3. Log out of any VIP Services you are having issues with (like Amazon, D+, Hulu, etc.)
4. Exit SF (again, you want to make sure SF and QCEF are not running)
5. Wait about 30-60 seconds to ensure QCEF.EXE process also closes (or in SF settings, Uncheck set for "Auto Start Upon System Startup" and reboot)
6. Navigate to your LOG folder
7. Delete everything in log (If you can't delete QEF.LOG, QCEF.EXE is running so use Window's Task manager to end QCEF.EXE process)
8. Navigate to your TEMP folder
9. Delete all files in temp
10. (optional, but recommended) reboot
11. start SF
12. Log into any VIP Streaming services (Amazon, D+, Hulu, etc.)
13. Try download again

[KidJoe]

Where do you find the offline installer?

As mentioned above, I usually recommend using the offline installer with the FAB app closed to upgrade/update, instead of using the "Update Now" button on the app's new version pop-up.

The latest offline installer can always be found at -> https://www.dvdfab.cn/download.htm I download and save each version as they come out, and keep them, so I have a local repository of older versions.

If you paid for the $9.99 (USD) Extended Download Service option, you can visit the Member Center , log in, and use the option on the left for Extended Service.

Or you can try this.....

You can just use this: https://github.com/hyugogirubato/DVDFabExtendDownload

Why isn't StreamFab working? or... This was working now StreamFab is broken again!!

I had posted a version of this, laid out slightly differently, on Reddit, but I figured I'd post here too because its still relevant.

Let me start by again saying... I DO NOT WORK FOR FAB, nor am I affiliated with them in any way beyond being a long time user of their products including DVDFab and most of its modules and add-ons, Passkey, DVDFab DRM Remover for Apple (discontinued), Unifab (since they split DVDFab AI Enlarger off into Unifab), and of course StreamFab for Windows (purchased when it was still DVDFab DRM Downloader), and StreamFab for Android (although it hasn't been updated in some time so doesn't really work for much beyond Youtube and some porn sites).


I've seen a lot of "StreamFab is broke again" or "why isn't this working" posts. So I wanted to share a few things to consider, followed by some troubleshooting/helpful tips... (sorry to those using mobile device to view as these bullets may run together)

• We all know that DRM changes on a Streaming Service Web Site will negatively impact StreamFab, but so do slight code or layout changes in the underlying HTML/CSS/JS/etc. Unfortunately, these can result in issues that look like FAB broke it, but sometimes they are not. For example, when Max finally converted other countries from HBOMax to Max, they (MAX) were still making tweaks to their web sites, which was breaking both StreamFab, as well as their former competitor, the late Anystream. Issues such as poor audio, unable to decrypt, and even no option to download. Its easy to think this is/was a StreamFab issue, but it was not. Its a Streaming Service side issue. Yes, Fab still needs to address and work around the change but its not a case of "Fab broke this" like many try to say.
• Some Streaming Websites might use different code based on Geography. This can result in a situation where XX service works in Country A, but Country B has an issue. Again, we saw this with MAX in Europe recently. You could still download from MAX in North America, but MAX in Europe had an issue. So its always a good idea to say what geography the streaming service your having issues with is located.
• Mac users get the short end of the stick. Development of the Mac version always lags behind the Windows version. Sometimes its only days, other times it can be weeks. Unfortunately Fab licenses are OS specific, so if you want to run the Windows version in a VM for example, you'd have to buy a Windows license for the modules you want to use. This is not cheap. Since VirtualBox is available for Mac OS, using something like this -> https://forum.dvdfab.cn/forum/softwa...her-win11-apps could help Mac users run the Windows version of StreamFab if they have the StreamFab Windows license.
• You think Mac users get shafted? Look at the Android version of StreamFab. Its last update was July 2023. Right now, its only good for downloading from YouTube and a few porn sites.
• There are pirated copies of StreamFab and its clones out there. I've seen several people mention using cracked/pirated copies on Reddit. They don't always work and can have bugs the official versions do not. If you didn't buy a legit license, you are stuck using it as-is. If you are experiencing an issue while using a pirated or cracked copy, there is nothing anyone can do to help you and I would suggest you don't even bother posting about your issue. If you want support, buy a legit license.
• StreamFab might quickly release a new TEST build for an issue, like the issue with the Max not analyzing/downloading bug several weeks ago. When they do this, it might be posted in a thread discussing the issue and they might not change the version number, so you need to watch that you used the new "test version" installer, not the release version installer that has the same version number. For example, after releasing 6.1.8.4 , and the MAX issue was fixed, Wilson.Wang of Fab posted a test version with a fix that still happened to be 6.1.8.4. This causes some confusion if you just say "I'm using the latest version"
• FAB developers are human, so they are not perfect. Yes, sometimes they do put out a release that fixes one thing and breaks another. BUT other times, its a streaming service change which is out of their control and just happens to coincide with them releasing a new version. For example the there was an issue recently of Max not analyzing and giving a download pop-up. It was working on 6.1.8.3, but when people upgraded to 6.1.8.4 the problem came up. It was coincidence as those who didn't upgrade also experienced the issue. It was a change on the Max side, but it looked like it was a Fab side issue. Thankfully they (FAB) put out a "test version" that fixed it, but the link to it was buried in a forum post about the issue, and they didn't change the version number.

When reporting bugs, its important to state the geography you are located in, what service you are having issues with, what version number of StreamFab you are using (please don't just say "latest version"), what platform (Win or Mac) and share the logs in the official forum, or use the feedback option in the StreamFab app. NOTE: When posting a bug/problem and your logs in the official StreamFab forum, its best to tag Wilson.Wang and DVDFab Staff in your post. Using the Feedback option is more private. Posting in the forum you might get peer feedback or help in addition to help from Fab employees.


Trouble shooting tips (I don't have a Mac, so these are geared primarily to Windows users):

1. It has been posted/suggested many times in the forums that using the "update" button on the pop-up notifying you of a new version has been a source of some issues in the past. Its not consistent or reliable. The better option is to upgrade by using the Offline installer. If you did use the "update" button and are having issues, download the offline installer and install it over top of your current installation. EDIT: For Windows the Offline Installer is available at -> https://www.dvdfab.cn/download.htm usually directly via -> https://www.dvdfab.cn/mlink/download...=StreamFab_x64
   1. There are posts out there suggesting even more drastic measures of using a professional uninstaller to fully uninstall, clear stuff out, and so on, then re-installing with the offline installer. For example see -> https://forum.dvdfab.cn/forum/softwa...447844-6-1-9-3 If you're really having issues and want to make sure you have a complete, up to date and fresh install, this is definitely worth a try.
2. As mentioned in a post above, for Windows Users the Default locations of Temp and LOGs FAB uses for all their programs is My Documents. On Windows, if you are using OneDrive, these folders are going to be synchronized with OneDrive. This could impact StreamFab's performance. If OneDrive is trying to sync a file, it will be locked as "in use" and if Fab goes to access it, it can't until OneDrive is finished. So MOVE your Log and Temp folders outside the reach of OneDrive (example, make a folder on the root of your C drive call FAB, create StreamFab Log and Temp folders there, in StreamFab use the 3 Bar menu and change the Log/Temp folder locations. Re-Start StreamFab.
3. When experiencing issues, a large number of issues seem to be fixed by doing the following steps (once completed, you'll need to log back into each service via StreamFab again): (also see post 11 of this thread)
   1. On the Home tab, scroll down to the bottom, the Recent History section, and select Clear History.
   2. Check both boxes for Browsing History and Cookies and other Site data, and click Clear Data.
   3. Use the 3 Bar Menu in StreamFab and got to Settings.
   4. Make note of your Log and Temp folders.
   5. Exit StreamFab and wait about 30 seconds before the next step
   6. Navigate to, and the Log and Temp folders and delete their content. NOTE: If you get prompted that a file can't be deleted, wait and retry, or hit Windows Task Manager and make sure QCEF.exe is not running, if it is, end task.
   7. Restart Fab and try again.
4. Sometimes the Fab developers mess up. Yup it happens.

Resolution vs Aspect Ratio....

As StreamFab tries to download at 4K, 1080p, 720p and 480p, there are some "odd" resolutions that aren't normal. So for example, I've downloaded Twister from Max and it was 1600x666.

So now is a good time to talk about resolution vs aspect ratio. There may be better explanations out there, search for letter box and pillar bar or pillarbox for example.

A typical 1080p TV or Computer Monitor is 1920x1080 resolution which is a 16:9 (aka 16x9) or 1.77:1 or 1.78:1 aspect ratio. 4K TV's are 3840x2160 which is also 16x9. An image or video needs to be 1920x1080 or 3840x2160 to fill the entire screen.

Have you ever watched a movie and the image hasn't filled the entire screen. Instead it has some black bars along the top and bottom of the image? That is called letter boxing. Its because the Movie was shot at a different aspect ratio. Popular aspect ratios for movies are 1.85:1, 2.0:1, 2.35:1 and 2:40:1.

With downloads, sometimes those black bars are included as part of the video to pad it out so that its 16x9, other times the black bars are not in the image, so the image will be "different" resolutions, and the TV and Playback Device add them during playback.

The same can happen with "old school" TV programs, where the TVs were 4x3 aspect ratio, so with today's wide screen TVs, you'll see black bars along along the left and right. These are Pillar Bars, and they fill out the image to fill the screen. Early episodes of the Simpsons for example originally aired as 4:3. Disney+ has also Panned and Zoomed them to make them 16x9 without bars.

So here are some resolutions you might see, and the aspect ratio:

Because aspect ratios vary by content, you could see the following for 720p when the black bars are not part of the image:

1280 x 692 which is 1.85:1
1280 x 640 which is 2.0:1
1280 x 544 which is 2.35:1
1280 x 524 which is 2.4:1
960 x 720 is 4x3 or 1.33:1 (think old school TV shows)

For 1080p without black bars included you'll see....
1920 x 1038 (sometimes 1040) is 1.81:1
1920 x 816 is 2.35:1
1920 x 800 is 2.4:1
1440 x 1080 is 4x3 or 1.33:1 (think old school TV shows)

For 4K, or 2160p, without black bars included you'll see:
3840 x 2076 which is 1.85:1
3840 x 1920 which is 2.0:1
3840 x 1634 which is 2.35:1
3840 x 1600 which is 2.40:1
2880 x 2160 which is 4x3 or 1.33:1 (think old school TV shows)

As further example, watch The Dark Night Rises on Max. its shot at 2.4:1 so you'll see black bars top and bottom. Then download it using StreamFab. It should download at 4K since its older. While 4K is 3840x2160 when 16x9 or 1.78:1 aspect, The Dark Night 4K downloads at 3840x1600, not 3840x2160, because its 4K at 2.4:1 aspect and the black bars are not part of the image.

The there are ODD resolutions. I mentioned 1600x666 before. Some may improperly label this as 666p, but its not. Its technically 900p at 2:41:1 aspect ratio. 1600x900 (aka 900p at 16x9 aspect ratio) is considered HD+ by monitor makers see -> . And there is 1024 x 576 which is 576p at 16x9 or 1.78:1. You might see 1024x428 if a video is 576p at 2.4:1 aspect.

4K HDR Formats and the effect on the look during Playback.

1080p TVs and monitors are SDR only. They do not support HDR, HDR10, HDR10+ or Dolby Vision.

When downloading 4K, and even some 1080p, H265 videos from Max, Hulu and others, the downloaded videos will include either SDR, HDR10 or Dolby Vision. Depending on your playback equipment and software, this could impact the colors you see when you play them. For example, if your entire setup doesn't support Dolby Vision but the video is encoded with Dolby Vision, the video will have a purple color to it when played back.

Its important that all of your equipment and playback software "in the chain" support the standard you are attempting to play back. If once piece doesn't support the standard, the "chain is broken" and the colors will be off. Example: While I'm using a FireTV 4K Max Gen 2 which supports both Dolby Vision and HDR10, my Sony XBR43X800D TV only supports HDR10 not Dolby Vision, so I get purple when playing back a file encoded with only Dolby Vision.

To check your files for HDR and what type, first, download and install MediaInfo . Once installed, if you are running Windows right click on the movie, open with MediaInfo. (I don't have Mac or other OS, so I can't tell you how to launch this beyond Windows). Inside MediaInfo use the View pull down menu and select Text. Next, locate the HDR Format line.






If you do not have the HDR Format line in the Video Section, your file likely does not contain HDR, and its SDR Only. This will play and look fine on any setup.

If you have HDR Format line. You may need to expand the window to view the entire line. Read it carefully and look for one of the following strings included on that line:


If you see SMPTE ST 2086 the file is HDR10 only.

• All of your playback equipment must support HDR10 or HDR10+ or the colors will look washed out, or like the colors are faded, during playback.

If you see dvhe.05.0x the file contains Dolby Vision only.

• All of your playback equipment/software must support Dolby Vision, otherwise it will have a purple tint during playback.

Example: While I'm using a FireTV 4K Max Gen 2 which supports DV and HDR10, my Sony XBR43X800D TV only supports HDR10, so I get purple when playing back dvhe.05.xx files.


If you see dvhe.08.0x or dvhe.07.0x the file contains Dolby Vision, but also includes HDR10 as a fall back.

• If all of your playback equipment supports Dolby Vision, then it will play correctly with the DV tone mapping
• if any of your playback equipment doesn't support Dolby Vision, but it all does support HDR10/HDR10+, it will play correctly using the HDR10 mapping.
• If neither of the above two conditions are met, the video will have a green or purple tint, or look washed out during playback.

Example: When playing on my FireTV 4K Max 2nd Gen stick with my Sony XBR43X800D (only supports HDR10) these files play in HDR10 mode and the colors look fine. On my Sony 77A80J along with my Shield TV Pro and Pioneer Elite Receiver (all support DV and HDR10), the same video plays in Dolby Vision mode and looks fine.


Note:

• Some PC software like VLC Player and DVDFab's PlayerFab have an option to tone map the HDR10 videos to SDR, and so videos with an HDR Format of SMPTE ST 2086, dvhe.08.0x or dvhe.07.0x will play properly, even if your hardware doesn't support HDR10. Unfortunately these apps do not appear to tone map DV to either SDR or HDR10.
• Plex Media Server also has a Tone Mapping option on the Transcoder settings screen. If toggled on, and your player doesn't support HDR10, the server will perform the tone mapping to SDR so the colors look right. There does not appear to be an option for tone mapping of Dolby Vision to HDR10 or SDR.

If downloading 1080p files and you want them to be SDR, but you select H265 and get 1080p with HDR instead (I've experienced this with Max), the only way around this seems to be selecting H264 for the download instead.
