AVC to VC1 - how?

[sucker]

hi guys

i´ve searched and didn´t find anything, if i overlooked it please point me in the right direction

i have a small AVC .m2ts clip that i want to reencode to VC1, is that possible and what do i need if it is?

DGAVCDec to index and demux audio -> Avisynth script on the index -> WMEncoder 9, WMVMuxer, Nic's WMEnc, etc. -> VC-1.
Demuxed audio -> Avisynth script with NicAudio, downmix as necessary -> WMA encoder of your choice if you care about ASF format.
VC-1 video + audio -> mux with MKVMerge if original audio, mux to WMV/ASF with WMVMuxer if ASF audio.

What's the reason for wanting to transcode to VC1?

i have the original .m2ts and the already demuxed files (demuxed with eac3to), do i need to demux again with DGAVCDec?
my goal is to just convert the AVC video to VC1 and then mux it back together with the untouched audio to a .m2ts
the reason i want to do this, is to append a 2nd .m2ts in tsmuxer but that doesn´t play correctly cause of 2 different video codecs (2nd file is VC1) so i want to transcode the 1st and very small clip to VC1 that it plays seemlessly
i installed avisynth and have MS VC1 SDK encoder installed, can i use them together, if yes how, never used avisynth before so i´m pretty much clueless about that tool

Try MediaCoder.
No demuxing, no scripts, no extra tools. Just encode from the original m2ts.

Don't use MediaCoder. It's a broken piece of junk and exists only to trick video newbies into thinking they can get results with no granular control.

No, DGAVCIndex can handle .ts, .m2ts, .h264, and .avc. Either the original or the demuxed will work, though if you're short on disk space you can just delete everything but the original M2TS and work from there.

Look for AVS2ASF which is built on the SDK and modified by Kurtnoise and some others. Make an Avisynth script to your liking in MeGUI or AvsP or some other GUI and then pass that to AVS2ASF at the command line. Alternately, if that's too much work, just use the AVS script in Windows Media Encoder 9 - it uses a slightly outdated VC-1 encoder as far as I know, but should produce compliant streams and at Blu-ray bitrates won't matter IMO.

You should provide evidence before calling it "junk".

VC-1 is less supported by hardware when you're talking about consumer videos (DVDR, BDR etc.).
