Vc-1

Does VRD support VC-1 in any kind of way? I have 7 videos (main w/ lots of smaller files and decrytped) ripped from Bluray that are VC-1 and complain when opening. I have never worked with VC-1 before. One is complaining that "No Audio stream found" and then "Unable to open file". Smaller files seem to open but all I see is a black window in VRD, no video no thumbnails no audio tracks and VRD just sits there with the cursor circling.

That should work. But we don't support VC-1 natively, so we're depending on ffmpeg to decode the file and feed it into VRD as uncompressed frames. That can be hit or miss with some formats. The audio might also be a problem. Our DTS support is limited and doesn't work that great with DTS-HD.
 
My goal is to convert the VC-1 to MP4 so I can get a smaller size. These ripped videos do not need editing just recoding for archiving/streaming. However I have tested a few that are MP4 with DTS and they play ok.

The smaller files mentioned above, after further analysis, if they are < 1GB they are MPEG-2 containers >1GB they are VC-1. So I was mistaken initially. Even the ones that are 1.5GB tries to load but poops out or just hangs.

But thank you for letting me know, I guess I need to look elsewhere for a VC-1 converter.

PS: I noticed that of the 7 videos I have that are VC-1 they are from the 1980's. Seems like that format did not last long. :confused:

VC-1 is a modern format designed by Microsoft to compete with H.264. It's really only used for BluRay, and only a few.

Careful. VC-1 is a codec while MP4 is a wrapper.

As mentioned, the codec is alive and well. The 31 disc Harry Potter collection has VC-1 discs.

Why not wrap with MKV? IMHO, it is a better wrapper than MP4.
 
It is already mkv with video VC-1. I need to recode smaller and into another format. My PCH does not like VC-1.

After doing research I think I found a solution. Avisynth can not recode VC-1 but avisynth+ can. I downloaded StaxRip 1.4.0 and it recoded all the movies. I just need to watch now. :)

Sorry, I assumed that you were talking about the VC-1 that comes within the M2TS file on a Blu-ray.

Technically AVISynth does not rencode. It is a server/video manipulator/filter between the input video and the encoder, which is normally x264.

I use AVISynth with no trouble at all when dealing with VC-1 videos. In my case, the AVISynth script uses the DGDecodeNV dll program, along with its companion, dgsource, to reduce the VC-1 video to raw video that is then fed to the x264 encoder.

Works great.

Yes it did come from a Bluray disk. It just got re-containerized to mkv.

Yes thank you for the explanation. I remember reading about the description for AviSynth+. I can not keep these fracking definitions straight. :)

Things that I read about VC-1 that not many things can handle it nicely.

Have you tried Handbrake?
I avoid it like the plague.

In my research that are a number of "downloads with gui frontends" that had some kind of trouble either blowing-up or creating pixelated scenes. MeGui and handbrake were mentioned.

StaxRip works similar to MeGui in that it exposes all of the x264 features for tuning and it auto-detected VC-1 nicely.
