jit.qt.record with reverse playback

May 6, 2011 | 3:09 am

Hi,

Is there a way to record a video with jit.qt.record and play it back backwards? like a frame count but you can tell it to start at a certain frame and decrease the frame count or something like that?

simply doing "rate -1." will play it backwards at normal speed. I’ve found that using tons of "frame $1" messages can play back less smoothly, and I’m not sure how well the audio tracks along. The audio can also be a problem when doing lots of rate changes, especially backwards…the video is always fine, but the re-processing of audio that QT tries to do can slow things down and sound funky.

If you don’t have any audio in the movie, you’ll be totally fine :)

(note that this is different than having an audio track and saying "vol 0.")
