Lisa - thanks for jumping in. I'll tell you what I did and maybe it will make sense to you - something might jump out as something I did wrong? I opened a .avi file in Premiere then exported the timeline as a tiff sequence. I then opened that sequence in Maya Live - I can scrub the timeline and see the sequence. Then I set tracking points, hit start track, and it errored out. Are there any special settings I should be using when exporting a tiff sequence or special importing settings when importing the sequence. Any advice would be greatly appreciated - and BTW - I think you should definitely put together a tutorial
