Recently I recieved a short DV stream from a friend. It's NTSC, I believe, but I'm not sure.
When I play it on this system, which is PAL, the ratio looks wrong and the video has lines on the edges of objects. Fine. Out of ratio, whatever.
When I play it, the ENTIRE SYSTEM lags extremely badly until it stops.
I *need* this video to work on a movie. Does anyone know what the deal is?
Seems like a QuickTime problem... I might "downgrade" to QT4 Pro... but nonetheless...
I've had this problem before. I erased my system, installed QT4, reinstalled FCP1 and recaptured all the media. That fixed the problem but I didn't have time to isolate the cause...

Ya I've noticed FCP converts PAL->NTSC and vice versa without maintaining aspect ratio. Never had a problem with lag though. Maybe the data rate is too high for your system?
So. Does anybody have a solution ?

The data rate isn't too high... I sorta wish that was it.
After I originally had the problem, I reinstalled OS9.1, QuickTime, deleted FCP2 and went back to 1.25 and recaptured all my media... and the problems vanished. I then went up to FCP2 and it worked like a charm the entire time.
Now this... blah. I'm gonna do the same again, I suppose, but I'm still worried; I'll be recieving video from different sources so I have little control over it. It's gonna be tricky...
Thanks for the reply

Well the aspect ratio will be out. If you're dropping the NTSC clip into a PAL time line you'll need to render it before you can play it back correctly. I think you're biggest problem will be the conversion of the frame rates from 29.97 NTSC down to 25fps for PAL. I've never had to do this before - although often times we'll drop in a quicktime clip with slightly different frame rates and i've never had any problem. So i guess that shouldn't be the problem.
What are you trying to do with the footage when the system is lagging? Is it simply trying to play in the preview window ?
You mention the video has lines on the edges of objects - Can you explain this ? If you've dropped the footage into the timeline and have the image+wireframe prefernce selected your clips will have lines around them so you can composite (I assume you already knew this but .....)
And as always post this on 2-pop
Sorry to be of little help.

This happens when capturing video too, with all settings right for the camera. So it isn't just NTSC clips.

Simply playing... even in QuickTime Player it does it. It isn't an FCP problem seemingly, but a QuickTime one.

Hmm. The objects bleed into each other ("object" meaning a shape with a certain, or similar colours) with horizontal lines... like bad MPEG1 compression.

Will do... and thanks for the help
I'm gonna mess around with QuickTime to try and fix it...
