frame rate change half-way into the video?

Avisynth does not support variable framerate video, and I dont think virtualdubmod does either.

WC Annihilus, yeah, I tried that, and it worked for clips of the same framerate, but not when they were 30 and 60fps... so yeah, I guess Zarxrax pretty much summed it up... it just isn't supported. I'll be re-encoding my video now at 60fps.

While I'm here, does anybody know of more amvs [like above] that have high framerates... I find stuff like that to be real eyecandy

For the record, MP4 supports variable framerate. It's created with the same tools you can make VFR MKV with (eg dedup), I've used it and never had an issue with it. However this was to maximise compression for a very high motion fansubbed trailer.

For AMVs though, it's likely not worth the effort since if you are just doubling up frames for the low framerate section, those will use hardly any space anyway.

Well I already re-encoded it, though it will probably be a while before release...

That's good stuff to know for the future, Zero1, actually I looked into it more, and <a href="http://avisynth.org/VariableFrameRateVideo">this </a> cleared up some things for me; basically pointing me in the same direction>> mp4... I guess I should go learn that now, eh
