Hi forumistas,

Does anyone know how to access/play different loop points from the one jit.qt.movie simultaneously? i.e. without having more than one jit.qt.movie object loaded with the same movie.
e.g. I might want to play ’0 to 1000′ and ’1000 to 2000′ and ’2000 to 3000′ etc… altogether
(trying to reduce the number of loaded movies to conserve cpu/maximise vid quality/increase speed/decrease latency)

i think it should be possible to dump a movie into a *very* large matrix, but i cant see that as being advantageous in terms of performance optimization, in fact it would probably be worst!

so i dont think what you are asking for is possible…

however, if u want to optimise your jit.qt.movie patches, u should take a look at vade’s website: http://abstrakt.vade.info/?p=147

hth,

BTW: this should be posted in the jitter forum!

sure, take a look at the multi-head quicktime example.

one step forward / one step back …

seem to have lost the sound on this one – is this an artifact of qball perhaps?

Also I am not understanding why metro is set at 100, except that the combined rate of two inputs to qball would be the usual 50. Does this mean that if I wanted up to nine or ten simultaneous loops that the metro would be set at 450-500? Clearly too slow for each individual loop.

sending the "start" message to the jit.qt.movie seems to make sound work.

this is just an example patch. you have to make it work for your needs. the metro 100 is probably just arbitrary.

post a patch if you need more help.
