Fast Playback / Rate in Jit.movie
Hey there,
I want to play back Movies really fast. jit.movie's rate parameter starts producing weird inconsistent results at rates greater than 8x.
Following things I tried:
- Codec QT Photojpg
- Codec DXV
- Resizing to tiny resolution -> I guess it's no Bottleneck due to HDDspeed or Footage
- Different CLocks of a Qmetro...
I get consistent 60fps on my jit.fpsgui... Any suggestions? Is it due to QuickTimes playback Restrictions or internal working? I might try dumping the Video to single Frames/Matrices and playing them manually in OpenGL. But before trying I might have skipped something here.
Thanks for any help!
yes, for extreme rate changes, you may be better off disabling playback (@autostart 0), and triggering via the jump or frame messages (use jump_true or frame_true if your movie codec does not have a keyframe for every frame). also, make sure your movie file does not have an audio track, as that can slow down processing.
