StreamFab v5.0.4.5 DRM MPD Module Incorrect File Size

[jsinfate]

Hello.
I used StreamFab to log in to Shudder and download a movie. StreamFab says the movie
is 1280x720 with Bitrate at 456000, but once the movie is downloaded the file size is only 380MB.

is this from Shudders own website or is it Shudder through amazon prime ??
might want to post the streamfab internal log files.

It is from shudder.com, the website itself.

shudder may not be a supported website yet - see post #298 - https://forum.dvdfab.cn/forum/softwa...20#post400312=

StreamFab detects that the DRM protection is MPD, so shouldn't it work? I am able to download from the site fine, it's just not that downloading at the correctly stated file size. I thought that it was the DRM technology that supported not necessarily individual websites?

different websites use different DRM protections. maybe shudder is using something that is not currently supported by streamfab.

If it wasn't supported would it appear as DRM MPD within the program or allow me download the movie at all? I would think that it just wouldn't work at all, maybe I'm wrong.

i have no idea, the developers would know more.

i don't see shudder listed here either - https://www.dvdfab.cn/drm-mpd-downlo...ckid=headmenu2

Hopefully one of them sees this and has some insight.

The file size is absolutely correct for the bit rates used. MediaInfo shows 372 MiB and the Bitrate Calculator at https://www.dr-lex.be/info-stuff/videocalc.html shows 366.6 MiB. Converted over to MB the movie file size would be 384.41 MB. You said 380 MB and your first image above showed 380812 KB (380.812 MB). Close enough. These calculators are always slightly off due to overhead and other unknowns. There's nothing wrong with the file size. The small size is the result of the horrendously small bit rate.

Well that's part of what I mean, I can't think that Shudder is streaming videos with a total file size of only 380MB, that's jut a little over half the size of a CD. I'm just wondering if anyone from the DVDFab team can confirm if these sizes are correct.

I downloaded Moloch from Amazon Prime via channel subscription AMC+ (Which includes Shudder on Amazon) via alternative software and it's 5,624,285KB size.

I also noticed it's 1920x800 AVC with bitrate of 7,536.

I *tried* to download via StreamFab, but the speed is only about 1.85Mbs vs. over 16Mbs for alternative.

I have it stored offline from downloading via Amazon/AMC+(Shudder) with StreamFab, let me grab the disk & I'll get it's specs via StreamFab/Amazon/AMC+(Shudder).

Speed of StreamFab download for Amazon with AMC+/Shudder is only 1.85Mbs

I grabbed a copy from another source that has been encoded into H265 that is also 1920x800. So it does seem that StreamFab is not only unable to download in full 1080p but it appears that it grabs the lowest available quality.

Moloch via Amazon prime with AMC+ Channel (That includes Shudder).

1920x800 AVC 8,145 Bitrate

File size 5,997,349kb

Display of download size indicated 5.2 (not much off) when I just tried queuing it up.

Just f/y/i...

Thank you for the information, I appreciate it.
