Anyway, I did a music video that required importing thousands of images (one video frame for each frame). I wrote my own script to generate the moho file (yay for text based files!) and it loaded fine, but I found that the program was slow to use (not really a surprise!!!) and also crashed quite often.
I noticed that when moving around the timeline the program would get slower and slower until freezing. I know that it was an unreasonably high load to place on the program, but I thought you might like to know...
Also, an "import multiple images" option would be good too

Good luck,
Luke
