I'm using XSI 3.0 for an animation project for my demo reel, and I'm having trouble getting an AVI movie to play in the background of my viewport for quick animation reference. Can anyone tell me how to get the AVI to play when I scroll through my frames?

Thanks

Anybody? Any suggestions would help, I'm probably overlooking something very stupid and simple.

Well, AFAIK XSI doesn't require any special setup for this. If the file you choose in the rotoscope options is an AVI, then it automatically advances it frame by frame when you scrub/play the timeline.

Have you checked if the AVI is alright, ie not corrupted or something. Also it might be encoded in some format that XSI has trouble using. Try with some other file or an uncompressed AVI...

not every codec can be scrubbed and played fbf.
my guess would be that you are using something popular but inadequate like divx, in that case (if you really can't but use divx instead of proper picture sequences :) ) you'll need to encode the avi with a Kframe every frame, or use something that is REALLY streaming for a codec.
Like mpeg1 or 2

I've tried uncompressed AVI and Mpgs so far and the only thing I get is the last frame of the movie in my viewport window. Do I need to precache somehow or how do I add a Kframe every frame like you suggested?

keyframing in time-difference based codecs like DiVX is specified at the encoding time.
if i may ask... why don't you just render a pic sequence out of the movie anyway ?
if you had the space to try with a bulky uncompressed AVI using a sequence of .PIC shouldn't be a problem.

Is there any particular reason ?
