Thank you very much for your attention,
now the patch runs smoothly and MIDI controlling is quick. I've tried like this:
- I've converted the videos with the AIC codec; - I've added the -nrt flag; - I've allowed double buffering on the window with a 50-milliseconds swap time; - I've removed the [pix_motionblur], even if I didn't experienced that Pd crash; - I've put [pix_film]--[pix_texture] instead of [pix_movie].
As I was in a hurry I've not changed things one at once, so I'm not sure which was the main trouble, but I'll check and tell you if it's useful.
All the best, Marco.

Hmm, when i create the GEM window, Pd crash. I need to remove [pix_motionblur] in video_movie.pd to create GEM window. ++

If this is on OSX:
Try using the -nrt flag for Pd startup. Also, the Apple Intermediate codec works better than JPEG for multiple clips.

Hi,
I'm performing a patch which uses four pix_movie objects with 720x576 JPEG .mov videos at 25 fps, with pd extended 40.3 on a MacBook Pro.
As I create the Gem window, the MIDI controller I use to set colour and movements starts being really slow, I have a visible latency on the values displayed in the numbox related and on all the video processing. The Cpu usage is never more than 35%, so I've found this quite unusual.
Anyone can help me? Thank you very much. Marco Liuni

i found that single buffer mode is incredibly slow on osx...(but probably i just used it in extreme ways not intended by the devs)
- I've put [pix_film]--[pix_texture] instead of [pix_movie].
blush, i haven't noticed you where using [pix_movie]; anyhow, once the pix is uploaded to the gfx-card as a texture you cannot change it with an effect like [pix_motionblur] (you would have to re-upload it)
the correct way to use these objects is really:
[pix_film] | [pix_motionblur] | [pix_texture]
anyhow, good it works now.
