VFR in WMV/VC-1?
 
Is it possible to encode Variable Frame Rate video into VC-1/WMV and if so how?

I am taking some softsub MKVs with VFR Video and trying to hardsub them to view on my PS3. Reencoding into either Divx 6.8 or H264 happens to be too slow for my taste so I've tried using VC-1 using a combination of Windows Media Encoder and Microsoft Expression Encoder along with Avisynth.

WMV does support VFR but good luck on finding any tools that lets you mux in timecodes manually. I don't know of any. If you do find any please let us know.

WMV is MANLY VFR.

When using Microsoft's tools to produce VMW files (Windos Media Video in ASF container) you automatically get "inferred VFR", it drops (mostly) duplicate frames and extends the duration of the previous one. If you use 120 fps (ugh) input I think you could get somewhat sensible results.

Wait, DivX and H.264 are slower than VC-1? I think you're doing it wrong, because the Microsoft VC-1 encoder is basically the most inefficient encoder I've seen except for actual reference encoders (e.g. JM). Well, maybe VP7 is worse, but since their standard is proprietary there's no way of knowing how complex the actual format is.

Could you point me in the right direction? I have very little idea what Microsoft Tools you're referring to.
