"latency" switching from rate 1 to rate -1 (jit.qt.movie)


assuming iam playing my movie at rate 1 (jit.qt.movie)
then with a button press switch to rate -1 the movie stops for about 500ms

i want to get this “latency” down as good as i can…

can you give me any tips how to?

(the same “latency occurs with imovie and movie object too. loadram 1 -> jit.qt.movie does not make a difference)

what movie codec are you using?
should be photo-jpeg, animation, apple intermediate, pro-res…

hey, thanks for your reply

i convert with quick time on win7.. i only have photo-jpeg and animation codec.
i get the same delay with both codes… not a ms difference.

i also tested converting the video with both codes in minimum and maximum quality, still the exact same result.

i have no delay in switching from rate 1 to lets say rate 5, once i play reverse there is also no delay in switching from -1 to -5 or so…

it only occurs while switching from something negativ to something positive…

any other suggestions?
