Sudenly my audio is not running at the smane speed as the film.
Can it be so that material used is in one frame rate (fps = frames per second) and Your movie project in another ?
• NTSC = 29.97fps (standard in USA (and more) and on many Cameras)
• PAL = 25fps (standard in EU (and more))
Same goes for 50i and 50p and 60i and 60p.
iMovie doesn't handle 50p or 60p as standard (as far as I know) but material need to be converted to 50i or 60i first.
Then I use JES_Deinterlacer to convert from 25fps to 29.97fps - when I need to do a NTSC-project.
fps in Your project You see here (in Project window)
first ona at 24 bildrutor = 24fps (frames per second) (why it became this I wonder )
next 30fps (NTSC)
last 25fps (PAL)
Mixing material with different fps - can in MY CASES result in Audio (out of sync./drift)
