Telecide/Decimate shortens length of material?

That's very interesting, sync! Thanks for pointing it out. I'm curious to know if you take the encoded AVI (the one that is too short by a second) and load it in VirtualDub, what are the numbers. Did it perhaps drop some frames, or did it set the frame rate wrong?

I goofed when I said Panasonic codec. That's what I used to capture with. If I use either the Pansonic or Canopus codecs in VirtualDub I get the message "cannot start video compression: the source image format is not acceptable. (error code -2)" when I try to save. So I saved uncompressed. I deleted the file and am running it again to get the numbers.

>the source image format is not acceptable That's because the frame size has to be 720x480 for DV (and something else for PAL DV). Take out your BicubicResize(). Anyway I made a test with Panasonic DV just now and it came out exactly correct.

Should I being using the defaults "Video - full stream processing", "Audio - direct stream copy"?

Is it possible to see how many frames are in an MPEG2?
