I added a groove~ in the patch, and it looped the audio in places I wanted but the video rate speeded up, instead of playing the 'corresponding' video frames.  I am guessing I either added the groove~ in the wrong place, or have to put a groove~ for the audio and a getlooppoints for the video that are synced?

This is really a matter of a bit of math. The phasor ramps from 0 to 1, which corresponds to the beginning and end of the sample. If you need it to ramp between different points, you'll have to multiply the output of the phasor with a value (between 0 and 1) and add an offset (between 0 and 1). I don't advise using groove since it has no high quality interpolation mode.

I'm sorry that I don't have time to explain this in more detail, maybe one day I'll make a patch that includes looping, time stretching, beat matching and everything ;) Until then I am afraid you'll need to figure this one out for yourself..

Best,
