efficient qt loading and use in performing live

March 11, 2011 | 1:31 am

hello

i am after the most efficient way of doing the following:

loadbang causes the loading of 40 short clips into RAM
insert the first 10 into 10 jit.qt.movies
when i turn a midi selector 1 to the right, replace the 10 movies with the next 10 in the list
the opposite when i turn it to the left.

i have a midi controller with (say) 10 buttons and (say) 1 knob used to select a set of clips for the buttons used to trigger them, so that when performing, i can access all 40 clips with a quick turn of the dial and bang, straight into the next set.

thinking about this problem i was thinking of inserting the audio/video onto individual tracks of a quicktime movie:

track 0 movie video 0
track 1 movie audio 0
track 2 movie video 1
track 3 movie audio 1
track 4 …

but there’s not much detail on the forum about addtrack and this feels wrong. also, the read message replaces the whole movie in the jit.qt.movie object. and i only really want 10 jit.qt.movie objects in my patch cos sometimes i might load 60 or 80 clips (I have plenty of ram).

any comments on how to do this most efficiently in terms of time loading and then in use RAM< ->GPU would be great. I’m using uyvy for everything already.
