In a patch to delay live and replay recorded video in a dance-show I have a problem of performance. There is video being grabbed from camera (firewire) that is send to a jit.window through a delay module (0 - 200 frames delaytime). This can be mixed with a recording. For speed sake I record into a jit.matrixset (1080 numbers) which would be good for a minute on 18 fps.).

When I hit the record button to start the qmetro for the recording the fps drops gradually from 18 to around 6 (which of cause is a problem).

The output is going into a jit.window that will be shown on a widescreen LCD-display.

Am I doing something wrong, or are there faster soluiton to record and playback?

Just in case of: Here is the patch for the rec/play option

could be many things. will have to see more of the patch to give better advice. if you can just strip out all but the relevant objects which still demonstrate the drop in FPS, that would help us help you.

also system specs would be good to know.


Take care: Initializing will take about a minute, because the jit.matrixset has 1080 numbers in DV-PAL resolution. So don't hit the restart button to soon. (-;

I work on a Macbook pro that is three years old.

Videoinput is while testing the iSight. For further testing there is a Dv-camera through firewire.

Output is on a second monitor now. Eventually it will be on a widescreen LCD from 48 inch.
