Blu-ray ripping produces a video file with many "green screens" and out of sync audio

[Kattanders]

Hi,
I am using DVD Fab 13.0.3.0 (Blu-Ray Ripper). Yesterday I came across my first blu-ray (Matrix) which I cannot rip. There are no errors shown, but the result has lots of green screens (see screenshot) in between and the audio gets totally out of sync.
Source is "Windows Media Video VC-1", "A52 Audio (aka AC3)"



What I do is to convert directly to H.265 HEVEC (2-pass). It makes no difference whether using MKV or MP4, 8 Bit or 10Bit). Converting to H.264 produces the same faulty video output
Audio I convert to AAC stereo 48khz/160bit. Trying with 1-pass doesn't help either.

Ripping with the 3D.H265 of DVDFab produces a proper video file (but I don't want 3D)


I can do video and audio pass through to get an m2ts file, and then use Vidcoder to convert to H.265 - also with GPU - which works for the video as well as the audio.

I did another test and disabled "all GPU codecs for decoding and encoding Video Decoder". The resulting Video is without the green screens. So it must have to do with the GPU encoding, however, Vidcoder, as already said, using GPU produces a proper video file.


I did then another test which solves the problem (disable Lightning-Shrink and set VC1 to "Software"):

Whenever I've tried to use Software decoding, the time it takes is way too long. I'm talking over 10hrs. for one rip.
What was the time difference for you when comparing VC1 Cuda vs. VC1 Software?

[Kattanders]

Matrix took about 20 mins with GPU decoding VC1 and 30 mins when decoding the source with software (CPU). The big work of encoding still was GPU. If GPU is totaly disabled we are talking almost 4 hours. In my case the faulty result was caused by GPU decoding of the source.
If all is done with GPU I can get as much as 200 f/s (H265) despite having an old PC (i5-8400 @2.8 GHz) with a, Invidia GTX 1050

Thanks for the info.
As for not being to use VC1 and Cuda, that is a DVDFab problem that they can fix, but haven't.
They've made silly mistakes in plenty of updates, like disabling hardware decoding in a recent one.

I guess though.
Still, it must have been about 50 blu-rays whch I have ripped so far - always with cuda enabled. Matrix is the only only one which didn't work. Glad I found that disabeling cuda for just the decoding sorted that for this blu-ray. Maybe it is a helpful hint for the developers that the decoding is one of the root causes.
Another problem I had was a scratch in one of the blue rays. It "overread" the bad parts, but as the decoded output was faulty, the encoding to H265 endet at the first fail (with success message). I encoded then the individual parts (start to end time), and then joined these with avidemux. I tried it first with DVDFab, but that resulted in losing audio sync.

The problem is with the audio format. They could've just missed including that format in their software.

i have the same problem with matrix. and also with matrix 2. i riped them for my nephew, but it cant be watch, because of the green screens and the audio out of sync. i thought it was a disc problem, but it looks like, it is a dvdfab problem and i also made few others. like forrest gump. all other, no problems. only matrix films have this problems, which i ripped yesterday.

Try using MakeMKV.
It'll take some researching to figure out how to use it, but it's free. You need to go on their forum and use the trial key that they post every month.

i have makemkv already, but i am using 99,999% of the time dvdfab. i also hjave dvdfab 12 installed on my computer, but i didnt try it wit dvdfab 12. but i think, this is a bug, and bugs can be normaly bei fixed. because, when it is a problem with vc1, i know, i ripped in the past a lot of older movies without a problem.and the same settings.

Have you tried to just disable the decoding VC1 as in my screen shot? Would be interested if that also fixes it for you, and also how long it then takes. Encoding still goes via Cuda

[gabberhead]

no, didnt test it. will also try it, when i rip them again.

[Kattanders]

no, didnt test it. will also try it, when i rip them again.

Please le'me know if it worked then.

Using the NVIDIA AI Enhancer in 13.0.3.2 is still resulting in audio being out of sync.
