Properly muxing Magix Vegas rendered raw AVC stream?

[lpmaskman]

How to properly mux a Magix Vegas rendered raw AVC stream?

I rendered an AVC stream from MAGIX Vegas with Magix AVC/AAC - > Blu-ray stream 25fps (plus AC3 stream separately) and I'd like to mux it into a mkv container properly.




I encountered in the following issues:

Trying to mux with ffmpeg:

first try:

Also MPC-HC detects is as an 50fps file. Also I tried to set the following flags in mvktoolnix header editor: "Field order: 1" and "Interlaced: 1".

Also I muxed it Tsmuxer into m2ts which was recognized as a proper interlaced m2ts file, but remuxing it into mkv will give me the mediainfo as above.

How I could produce a fully compatible interlaced mkv file from Vegas render?

[davexnet]

It may be OK, interlaced H.264/AVC usually shows something weird in the mediainfo related to the frame rate.
It's to do with the way the interlacing is stored as separated fields.

Timestamps are unset in a packet for stream 0.

For ffmpeg, use -bsf "setts=pts=DTS" to fix timestamps on elementary stream input

something like this

ffmpeg -f h264 -r 25 -i input.avc -i input.ac3 -bsf "setts=pts=DTS" -c copy output.mkv
