rendering video to audio

I gots me some audio fft aknowledging visualization software to watch my
music progression fft bins and make them explode visually and what not, I
wanted to render them in highresolution non real time but I cant seem to
sync them.. I tried making a matrixset that fills up a 129 lenght list 1
for amp 64 or right chaneel fft and 64 for left channel, I just run the
peakamp~ at 33 ms at fill in the list so 1 minute is 1800 frames for one
matrix 3000 x 129 it all seemsto work well the time code embeeded in the
video is on schedule I must have over looked something cause the video
renders for longer than the audio Im gonna try to shrink the video a little
bit so they are the same lenght but I was wondering if anyone else had
tried, im sure, to do non real time rendering of music, is it a good idea to
make an fft matrix first or should I pull directly from the buffer for each
frame. vauge pursuits our each individual programming experience, I just get
this feeling the the fft data Im pulling from doesn’t have to much to do
with the music cause I replay it through osc bank and its just all primative
vocoding, is there a fft sample rate, or interpolation to get a good
rendering….again vauge questions

First to check is if your dsp settings have checked “Max Scheduler in
Overdrive” AND “Scheduler in Audio Interrupt”. Else wise all scheduler
timing will remain in realtime, which would be wrong.
Don’t know about the video part…
