Dreamer, thanks for your help.
I am already using Pinnacle Studio7.
In clip edit mode, there is a clip trimmer
and loop player. However, there is a lag
time between when the loop ends and restarts
that throws off the musical timing.
I could live with a slightly jumpy video,
but the audio must be smoothly looped with
no delay or it's musically worthless.
I was wondering if there is some software
that could do this properly.
