imagine: i import an pal dv avi (captured with pinnacle dv500 in premiere), 25 fps, into aftereffets. duration is 4:30:22 (premiere and afterfx say so). i put the thing into the timeline and render it out again. than the final avi is 3 sec shorter than the original. and the funfactor: any time i try this the video gets shorter different- sometimes 2 sec, sometimes 4,...

the video was captured from vhs was black and white and is now in a color palette. i set all the controlls i know in aftereffects to 25 frames so it should not think it is ntsc.

is there anyhelp out there?
