OpenGL recording problems
For some reason, I always encounter problems when I get to the recording phase.
This time, Im doing a jit.desktop render, and I am having a couple issues.
The main one, that I cant live with, is the timing of the video, it
seems I have this issue regularly. I have tried with and without
Realtime enabled...and I still dont even get close. Without it, my
video is usually under 2 minutes (the original is almost 6). With
Realtime on, It records to about 4 minutes.
This is recording to a 30fps file, with a metro driving the
jit.desktop object at around 66.66 ms.
Is this the right setup? Kinda confused, since the .sit file on the
render options page is busted.
Thanks,
Computo
I think you want 33.33fps for a 30fps movie. 1000/30 = ?
I will look into this jit.qt.record realtime thing and see if I can
find a problem. But it will take a while, so thanks for the info.
We'll be in touch.

I such a doof, I was dividing by 2000.
but Ive tried every different variable, even at 33.33, and such...
Ive tried somewhere around 50 times, just trying to get the right group of
settings...
Basically, Im stuck.
Thanks!

For perfect timing for recording, you will need to do a non-realtime
record. You need to parameterize your patch in such a way that the
controls can be set on a per frame basis. You can make a live
performance recording the parameters to a coll or some text file, and
then read these parameters back stepping one frame at a time for the
non-realtime recording. See list archives for more discussions of
such an idea. I believe that Randy has been working on a good example
of this sort of thing.

Hey Joshua,
Can you suggest a method or patch that is going to lead me in the
right direction?
I get the concept, but I dont know if I have the knowhow to achieve this result.
Any suggestions? perhaps someone has a copy of Randy's patch?
Thanks all!

See this thread: " smooth rendering/writing to disk? "

You might want to have a look at the GestureRecord recipe in the "in
depth" section of the website. I believe it is in Book 2.
This presents 2 ways of recording parameters frame by frame. I would
opt for the pattrstorage method, personally.

You guys rock, I'll try those when I get home from work.
Thanks a million fellows,

Please hold...
