Proper way to handle a channel changing mechanism?

October 30, 2013 | 12:53 pm

I am working on a jitter project where I need to be able to "change channels" between different coll banks of videos. Right now I have each individual channel working, short clips cycle through randomly, but I don’t know the best way to the four channels into the jit.window object.

Each channel will have some distinct processing, so I can’t just change which clips the jit.qt.movie object is reading, the channels are distinct all of the way until the jit.window. Would it be too resource heavy to have different jit.qt.movie objects for each "channel"? I am new to jitter, so I am not really sure how it handles resources (are the jit.qt.movie objects the most resource intensive in this? Or will it be the jit.window?)

Also, is there a simple alternative in jitter to the gate object? So that I could select which jit.qt.movie object is being sent to the jit.window?

Thanks

you can use the gate object with jitter– all that is being sent down jitter patch cables is a text symbol to reference the actual memory space that the current video frame occupies.
i’d try using a different movie object /fx path for each vid ‘signal’ then maybe gate the output at the end; or send stop messages to the movie objects whenever not being used… you can also change the name of a matrix that another matrix references– that would probably be the most efficient method

I have the gate working now, and have it going back into a jitter matrix object. Thank you! I wasn’t quite sure how to go about referencing different matrix names though, I’ll keep looking into that.
