Motion JPEG codec

I have several videos that are made with the motion jpeg codec .avi that I need to edit. When I import them into FCP the timing is altered and the videos is freeze framed in parts of the clip. Any suggestions on what I can do?

g5, Mac OS X (10.5.5)

Transcode them to pro res using mpegstreamclip.

Here's a tutorial on how to accomplish this.

I tried exporting almost every way in mpeg streamclip and still it distorts my video. i'm getting desperate, i've been working on this all week and am running out of time, any other suggestions would be very appreciated!

Open a MJPEG file in QuickTime
type Cmnd-I to open the Inspector window
in the Format area note the image dimensions and whether or not there is a different dimension inside of parenthesis

When you export your file from MPEG-streamclip make sure you match these dimensions (numbers inside parenthesis over ride those outside the parenthesis), change to Custom if necessary.

You should also make a note of the frame rate (FPS) and let us know if it's not a broadcast frame rate.

Thank you so much for your help

What I have ended up doing was using compressor to export as an mov and then putting the video into fcp to edit. i noticed that when the mjpeg video is played on a pc the total time is 2 min but as soon as I put the video on my mac it speeds up by 66% so now the video is only 1 min 20 seconds long. i have over 100 of these clips to edit and the only thing i can think to do is to change the speed by 66 % before i edit. mpeg stream clip distorts the video so badly so i can't use that to edit and quicktime won't open them. has anyone else ever seen this or have a solution?

thanks again
