@ Lazzaro: yes I know, thanks for specifying, but the problem is that the duration of audio and video files I record don't match each other.
@ Cirylle: ok, now maybe I understand. I'm actually already using a similar abstraction of yours to monitor fps :) My patch is completely automatic, it's a sonification/visualization of large amount of data, thus I just press a toggle to start it.
So: if while recording the fps monitor shows 10fps, it means that also pix_write will record only 10 frames per second and _not_ 20 as I stated in gemwin, is that correct?
I was probably wrong assuming that whatever fps is stated in gemwin will be the recorded fps, even though the machine can't reproduce it in real-time.
Ok, so, if I can only record at 10 fps, what do you suggest to finally have a recorded video with a decent framerate? (apart from changing machine...) I guess I could use ffmpeg to double the framerate, but the video might be jittery...

here is a simple abstraction that output the real rendering frequency. it help a lot to track this kind of problem. c

Hi all, it's been a week now I'm struggling to record properly a GEM output, reading archives and forums.
I have fairly complex audiovisual patch with multiple geos, four pix_snaps to create motion blur effect for 1280x320 res, and data exchange through local network. However I can record in a really good quality using both pix_record or pix_write.
The problem is the recorded video is faster than the actual one.
Hi, apologize me if it is a dumb answer, but if you apply very intensive
motion bur and other stuf in your patch the speed of what you see in your gem box will be very slow. The sequence of images that is generated will necessarily faster than what you see when the patch is running.
