Hi,I have been trying to get DVDFab UHD Creator to pass an .mkv file through so i can make a full quality UHD blu ray of my video project. I have tried this with many different .mkv files and in all cases the program tells me it is an unsupported file type and asks if I want to switch to processing mode. Of course I want to use passthrough mode to retain the full quality of my production.I have two 4K UHD video projects. The first is about 45 minutes long and is in Adobe Premier Pro. The second one is 7 minutes long and is in DaVinci Resolve. It is HDR-10.DaVinci Resolve cannot directly produce .mkv files as far as I can tell, and it doesn't add the required HDR metadata to trigger HDR playback in a TV. So for my resolve files I put the file through Hybrid, both to change the wrapper to .mkv, and to embed the HDR metadata. I have been passing the .mov from Resolve through Hybrid, to produce the .mkv file I am trying to pass through DVDFab UHD creator. I have tried both H264 and H265. DVDFab does not recognize these files.Premier Pro also does not directly produce .mkv files. This project is not HDR, so I use Hybrid in its passthrough mode to change containers from .mp4 to .mkv. DVDFab also does not recognize these files either. I have also tried using both H264 and H265. All these 4K projects are of course, 3840 X 2160, at 29.97. I am using AAC audio. The bit rate is set lower by default in Resolve.What am I doing wrong ? How can I get my files to pass through DVDFab ?

If I understand correctly what you are attempting, I believe you are using the wrong module to achieve your goals. DVDFab UHD Creator produces only output with a 4K UHD BDMV disc-like structure, not mkv files. Try using the Video Converter module instead.

You Misunderstand. I AM trying to make full quality 4K UHD Blu Ray disks. This is my goal. DVDFab UHD Creator has two modes. These are process, and pass through. I have succesfully made a 4K UHD Blu Ray disk using process mode. But in this mode the video is processed and so there is significant quality loss. What I am trying to do is use pass through mode so my video is not processed, and I retain full quality. According to UHD Creator itself, it can use pass through mode with two file types only, .mkv and .m2ks. Of course Adobe Premier Pro and DaVinci Resolve do not export directly into .mkv or .m2ks files. My understanding its that these are just packages and the video inside is the same. So if I produce a H265 HEVC video in .mov, .mp4 or most other formats, the video is the same and only the package is different. Since UHD Creator uses only these two file types for a pass through disk, I have been using the program Hybrid in its pass through mode, to change packages from .mov or .mp4, to .mkv. I have also produced some .m2ks files this way. In all cases UHD creator does not accept my files and tells me they are an unrecognized type. It then suggests I use process mode. So my question is, why is UHD Creator failing to pass my .mkv files ? How can I get my files to pass through ?

When i first open UHD Creator I am presented with a UI that has a box in the middle and a "+" in the box. Above the box it says "Clcik on the + button to load a file". I click on the "+" and browse to my .mkv file. I load the file, which takes only a few seconds. Then i am presented with the message "DVDFab: ? OOps? Unsupported video file(s) detected ! The Passthrough processing mode of UHD Creator only supports MKV/M2TS HDR/Dolby Vision video files". Would you like to switch to conversion mode ?"Why does it not accept my .mkv files ?

Hi1. Please download MediaInfo (free) at , and use this software to analyze the mp4/ mov file produced by Adobe Premier Pro and DaVinci Resolve, then send us the analyzed files;2. Do you use Hybrid to convert the mp4/ mov to MKV? Please send us the media info of this output MKV file as well;3. If it is not a standard hdr10, it is not compatile with UHD, so it will be converted to hdr 10 or sdr. What is the format of your HDR?4. If possible, please upload a small sample file from both Adobe Premier Pro and DaVinci Resolve. I sent you a PM about how to upload the file.

Hi,Do you mean for me to download the JavaScript Module DLL V. 18.12 at the bottom of that page ? It's going to run in Windows 10 ?I do use Hybrid to convert the two file types into .mkvFor the .mp4 file from Premier I use passthrough mode in Hybrid to change the container only. For the .mov from Resolve I use processing mode in Hybrid to both change the container, and to embed the HDR metadata so the file will play in HDR.Let me know if I'm looking at the right download and I can start gathering and sending the requested data.

FYI, here are my settings for Adobe Premier Pro. .mp4, 3840 X 2106 29.97 FPS, VBR 1 Pass Target 20 MBPS, Max 25 MBPS, AAC audio, 320 kbps, 48 khz. Stereo, Progressive, H265 HEVC, Render at Maximum Depth, Use Maximum Render Quality.This project is currently just under 29 minutes long and it takes just under 6 days to render on computer A. The .mp4 file is 4,323,572 kb.Here are the settings I use for DaVinci Resolve. .mov, Quicktime, H.265, 3840 X 2160 Ultra HD, 29.97, AAC Audio, 192 kbps, 16 bit, main 1, Stereo.This project is HDR 10. It is just over 6 minutes long, takes only a few minutes to render on Computer C. The .mov file is 862,144 kb. After passing it through Hybrid, the new .mkv file is 168,129 kb.The Hybrid processed file with HDR 10 metadata looks almost as good as the unprocessed file, but it does lose some quality. Resolve will probably be able to embed the metadata by the end of the year and then I will not need to process the file in Hybrid.All three of these files play well on computer C from the hard drive. The Hybrid processed .mov file, now an .mkv, and the .mp4 directly from Premier, and the .mkv file created by Hybrid in pass through mode from the premier file, all play well from an external hard drive connected to my 4K HDR OLED TV via a USB port.

Today i created four files. They are small samples of my work. Two are from Premier and two are from Resolve. I spent the afternoon trying to FTP them as instructed. But I kept losing the connection and the uploads were constantly disrupted. The connection times out. Eventually it says there have been too many connections from my address and stops accepting connections. Our internet quality is not so good here, especially after a lot of rain. Fortunately after a short wait I am able to reconnect and continue the upload. I was able to upload nearly 25% of the smallest of the four files. I will continue this tomorrow. Perhaps the connection will be better tomorrow as it didn't rain for the last two days.

Hello, I reply in this thread because I have the exact same problem as the user Crash Landing.If you think I should open a new thred let me know, thanks.I state that I have the last version of the software, at the moment only in trial. If a can make it work, then I'll buy it.I want to use the passthrough mode in DVDFab UHD Creator, converting an MKV file in UHD Blu-Ray ISO (full quality, BD-100).I tested 6 (six) mkv file and none of these is supported by the program for the passthrough mode (it asks if I want to switch to processing mode).The mkv files was obtained from muxing UHD blu-ray video with regular blu-ray ac3 audio track (my language), everything is regularly purchased.The mkv files works great on PC and also streamed on Samsung UHD TV. I can produce txt files, if you would, of the mediainfo analisys.Let me know,thanks in advance.Michele

unable to get mkv videos to pass through.

Crash Landing

I managed to get the first file to resume upload. After another four hours it completed. I have successfully uploaded the smallest of four files. Inside my folder is a subfolder called DaVinci Samples. inside that subfolder is the file I uploaded. It is ShortSample.mkv 19,490,467 kb, and is something like 45 seconds long. To make this file I rendered a short portion of my Davinci Resolve file. Then I processed it in Hybrid to add the HDR-10 metadata and change the container to an .mkv file. This file is much shorter than the unprocessed file directly from resolve, which I haven't uploaded yet. That file is 82.500,281 kb.

Crash Landing

While FTPing, I inadvertently created two files and a folder. I tried to delete them but it wouldn't let me. I created another folder "Obsolete" where I thought I could move the unwanted files. It doesn't let me move files in my folder either. Please delete the folder "Obsolete", which is empty. The two files that need to be deleted are shorter versions of files we don't want to delete. They are ShortSample.mkv 2,224,866 kb., and ShortSample.mov 3,572,180 kb. These two files are located in the folder that needs to be deleted, which is a duplicate of a folder we must not delete. Both Folders are named DavinciSamples. the folder that needs to be deleted is inside the folder that must not be deleted. The folder that needs to be deleted has two files in it. The folder that must not be deleted has two folders and two files in it. One of those two folders is the one we want to delete. Please delete that folder, the obsolete folder, and this post. Just found another. There is one more useless file that needs to be deleted. It is ShortSample.mkv 1,310,720 kb. This is an even shorter version of the file I successfully uploaded, that we must not delete, which is about 17 times larger. Thank You.

Oops, in number 19 I accidentally typed mvk instead of mkv. Could you please fix that ?

Ashley

Thanks to you. I cut a 5 minutes sample from one of my UHD MKV (not touched anything, it's only a portion) and I've tested it in DVDFab to make sure it gives the same behaviour.
I've uploaded this MKV sample on FTP based on your instructions (my name and mail address), along with the log file from the program (dvdfab_internal log).
I also attached the log file in this message, along with the complete mediainfo analysis export file.

Hope you can solve,
Thanks in advance

In short, we only need the files in the DaVinci Samples folder? See my attached.

Many thanks, much appreciated. I hope this behaviour can be solved, so I can buy DVDFab and go on with my movies :)

Crash Landing

Just now I found there was a new update to DVDFab. I installed it. The behaviour has changed. I think I may have just successfully loaded the .mkv video from Resolve in passthrough mode. At least it didn't give me the file not recognized message. I then processed it and it did something. But I can't find an .iso file to burn the disk from, and I don't know how to make it burn a disk. It did create a folder in c user documents blu ray, My UHD Blu Ray, BDMV, there are some sub folders and I see a file MovieObject.BMVD
What do I do next to burn a disk ?

Crash Landing

I found the buttons that let me chose to produce an .iso or a movie file. I loaded the Premier video that had passed through Hybrid to change it to an .mkv. It also loaded without giving me the message. It is now processing. it is taking much longer to process, but it is a much larger and longer file. It will take about another 40 minutes, and then some time to burn the disk. So it will be some time before I can report my results. Here's my new question. If all this goes well and I produce a 4K UHD disk that looks as good as the source file, how can I confirm it used passthrough mode for the best quality, and didn't process it, other than making it into an .iso ? Is there a log I can send ?

Crash Landing

FYI, I am using re-recordable BD disks. I've been doing this for several years for my HD projects which get updated. It works well and saves using up a lot of disks when experimenting. I usually use Verbatum. They have single layer 25 GB, and dual layer 50GB re-recordable Blu ray disks. I could only find triple layer 100 GB re-recordable Blu rays from Sony. I have also been using 100 GB M-Disks successfully for backing up important data. You might also like to know that standard 4K UHD plastic cases are now available on Amazon. I am now burning the .iso to a re-recordable 100 GB BD using Nero, which is the only program I know is able to burn 100 GB triple layer disks and M-Disks. It works well for that, but I originally bought it because it was supposed to be able to do what I am now doing with DVDFab UHD Creator. But it couldn't and their tech support was unresponsive. The disk is now 13% completed. But there is the verification.

Crash Landing

The re-recordable disk I burned would not play. So I burned a regular 100 GB BD. It plays, but not smoothly. The video looks like it is playing at 7 FPS, or perhaps like it is pausing at 7 hz. Otherwise the video looks pretty good. But I think I am seeing some degradation of the image. What I am seeing is some slight color banding in two places, and some slight patchy noise in the most difficult clips.
I tried an experiment. I loaded the .mp4 file from Premier. I didn't get the warning. Perhaps I need to set it to passthrough mode before I load the file. I knew how to do that in the old version but don't see it in the new version.

Crash Landing

I do not see that I can set "pass through mode" in this new version !

@MicheleM79
Hi, your issue has been fixed. Please wait for the next new version, thanks.

Ashley

@Crash Landing
Your source ShortSample.mkv is not compatible with UHD. You can use Media Info to analyze the file information. It is Main 10@L5@Main. Not Main 10@L5.1@High.

Your file is lacking the following mastering_display information:
Mastering display color primaries : Display P3
Mastering display luminance : min: 0.0050 cd/m2, max: 4000 cd/m2

Thanks.

Hi Ashley,
I updated DVDFab to last release and tested the MKV file sample I uploaded to you (one of those who was giving the problem).
As you confirmed the problem is gone and now I can use the passthrough function. The program completes the work correctly
and creates the folder output with the UHD structure.
At this point, however, by looking at the resulting m2ts file I found a problem, I tested it with Media Player Classic, VLC and
DVDFab Player 5. The video is corrupt, about 1 min from the beginning.
I also have another request but let's solve one thing at a time :)
The MKV file to be analyzed is the same already uploaded, the log related to this test is attached.

Thanks a lot,
Michele
