muxing VC-1 encodes to m2ts

[02fx4dude]

Hi All,
Not sure if this is the right section or not.

I'm taking MPEG2 files, captured OTA, and using Avisynth/WMNicEnc to encode to VC-1, with the intention of using TSMuxer and TSremuxer to create blu-ray folders to burn to DVD+R. After encoding I end up with a WMV file, which plays fine with windows media player, but TSMuxer doesn't recognize the VC-1 stream. I used Mplayer to strip out the raw video stream but TSMuxer still doesn't recognize the stream.

Is there some simple step I'm missing?

TIA

Brian

This section is only for Blu-ray to blu-ray backups. Moving you to our blu-ray authoring forum instead.

Does tsmuxer support vc1? Does it mention it the readme? Or else would I convert to h264/avc.

TSmuxer 1.4.6 says it supports VC-1 video.
Use ASF2VC1 for getting a compliant elementary stream from an ASF container.

Well Midzuki, ASF2VC1 seems to be the step I was missing. Although for some reason after I extract the stream, TSMuxer thinks the frame rate is 23.97, instead of 29.97. But that's easy to fix with TSMuxer. I'm encoding a 45 minute clip right now so I expect to know sometime tonight how it looks playing in my bluray player.

Much Thanks

Brian

Okay, I have discovered TSremux assumes every 29.97fps video is
"necessarily" a 23.976fps video with pulldown flags --- which is a bad feature
if you happen to be dealing with a progressive 29.97fps source (the resulting
m2ts file will become a macroblock festival when played back )
The safe choice is to run asf2vc1.exe with the option "-nfrm" and then
input the correct framerate in the TSmuxerGUI window. Good-luck!

Hmmm, that's interseting.

Initially I let TSmuxer just let it go with 23.97, even though I specified 29.97 when encoding. After muxing the m2ts I played it in PowerDVD ultra and it played back jerky. Not a random jerking, but almost like a strobe effect. I muxed it again with TSmuxer set to 29.97 and it played fine in PowerDVD.

I'll try the "-nfrm" option.

I did mux a 720p movie last week with TSmuxer, but TSMuxer had correctly identified it as 29.97fps. But when played back it was showing a similar jerking. I was assuming it was to high a bitrate for the DVD+R discs or my Samsuck BD-P1200 player, or both. That was an MPEG2 file.

Again, you're very helpful, thanks
