Using the old prediction method I would get mismatches of a dozen or two frames. Not normally a big deal, but it is for our purposes.



I will try that out once GripFit is released. I don't want...

Note that SelectRangeEvery doesn't seem to be quite accurate. The old prediction method, which used SelectRangeEvery, produced sample strips that had a frame count fairly significantly different from...

The frame rate is only used by Sampler as a default sample length if none is specified -- it's not a part of the formula. I figured that movie-length-in-minutes samples of one second each would be a...

Roughly, though I believe the SVCD filesystem is slightly different, so will have slightly different overhead.



The figure I gave (813,019,155 bytes) is compensated for filesystem overhead and...

They should always be multiples of GOP length. If your frame rate is not 23.976, you should specify the sample length, i.e. Sampler(length=24). If your frame rate is 23.976 you can just use Sampler()...

Then today's your lucky day, because you can indeed get a maximum of 800mb on a VCD. To be exact, 813,019,155 bytes :).

With the new formula one uses minutes-in-movie samples of max-gop-length frames. At the moment that's 24 regardless of frame rate :).
