I think that if you set a frame rate higher than your hardware can display, it will skip frames to attempt to make a 10 second clip only run for 10 seconds. I currently have the best results running about 12 frames/sec, but I don't have my machine decked out yet. The store still owes me 64meg (total 128meg) but until my radiator died last night I was gonna pay a wee bit extra to go directly to 256meg. After I get that, I will do a few more clips to see if I get better results. What hardware do you have? I have an 800mhz Athlon with 64meg (my board will handle 1gig, but I don't gots that much moey now...)
