Thanks Cyrille,<br>I made different tests and I noticed what you said about the fps, that's a very good tip.<br><br>Besides, I realized that I can gain 5/6 fps moving the gemwin in another workspace (different from the one I actually see).<br>

if you want a 1 min video, use a delay 60000 to start/stop.<br>
then, it will be perfect, even it it take 2 or 3 min to record...<br>

oh, ok.<br>
Thanks Cyrille, you threw some light over my confusion.<br>
<br>
I now understand what you meant.<br>
I'll give it a try waiting longer.<br>

@ Lazzaro: yes I know, thanks for specifying, but the problem is<br>
that<br>
the duration of audio and video files I record don't match each<br>
other.<br>
<br>
@ Cirylle: ok, now maybe I understand.<br>
I'm actually already using a similar abstraction of yours to<br>
monitor fps :)<br>
My patch is completely automatic, it's a<br>
sonification/visualization of<br>
large amount of data, thus I just press a toggle to start it.<br>
<br>
So:<br>
if while recording the fps monitor shows 10fps, it means that also<br>
pix_write will record only 10 frames per second and _not_ 20 as<br>
I stated<br>
in gemwin, is that correct?<br>
<br>
no, it will take 2 min to record 1min of video at 20fps.<br>
<br>
<br>
<br>
I was probably wrong assuming that whatever fps is stated in<br>
gemwin will<br>
be the recorded fps, even though the machine can't reproduce it in<br>
real-time.<br>
<br>
Ok, so, if I can only record at 10 fps, what do you suggest to<br>
finally<br>
have a recorded video with a decent framerate? (apart from changing<br>
machine...)<br>
<br>
waite longer...<br>
<br>
I guess I could use ffmpeg to double the framerate, but the<br>
video might<br>
be jittery...<br>
<br>
no, the video will be perfect, since everything is done with pd time.<br>
pd time is no more real time, but that just a question of cpu/gpu.<br>
everything else should be exactly the same.<br>
<br>

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

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