Pulldown is not necessary for video in the MKV container - it can be 24fps (or 23.976fps) natively.

So, capture produces a DV file at one film frame per DV frame (which isn't 24fps). So... I would edit the movie in DV (at its framerate), do a temporary pulldown like before so I can sync the audio, then do a final encode at 24fps? How would I get the audio correctly into the mkv encoding?

In other words, although the film is meant to be played back at 24fps, the video is stored at 30fps (too fast) because it is captured as a DV .avi file, and the audio is a separate .wav file. I need some way to sync them up, and also to tell the encoder to set the frame rate to 24fps.
