Hddvd 24fps?

[oddball]

I read someplace that HDDVD is actually 24FPS progressive and not 23.976FPS which would be 1 dropped frame on current HDDVD encodes ever 80 frames or somesuch. Is this true? I heard that nearly all the tools like Avisynth don't have true 24FPS capability?

Most HD DVDs that have come out so far are true 24.0fps. This part is simple, but the rest is not ;)

If you want to load a decrypted HD DVD into avisynth, the only way currently is to load it via directshowsource(). The only demuxers available for computer playback all currently change an output framerate of 24.0 to 23.976, by selectively dropping and duplicating frames. Since some frames are dropped, this is a destructive process which cannot be reversed at this time.

Avisynth is essentially framerate independant. Because avisynth deals in frames, rather than fps, it doesn't really matter what framerate is fed in. For avisynth the framerate is just another video parameter.

Wrong.

You must be confusing cheap DV cams with Avisynth which can handly 1-1500 (I tried that) and probably even more frames per second ;)
