Quick Quicktime (mov) question - Urgent.

Hi all,

I just got a contract this afternoon and the guy supplied me with a mov file from quicktime. He claims that it's uncompressed (I always thought that AVI wass always uncompressed, anyways). So I open up vegas back at the office (V7.0d) and open up the quicktime file...okay I am missing teh quicktime plug-in so I install quicktime V7.0.4 full.

Now it opens and I can play it in the trimmer but it's too jittery...it just chuckles along and it doesn't play smooth (it jumps frames and the frame count in the preview viewer always shows the dots, i.e. FRAME: 183.... ). If I do a pre-render on a section it plays extremely nice...

Properties on the file show Video 720*480 29.970 fps interlaced, DV/DVCPRO - NTSC, 16-bit Endian.

How can I get this thing to play smooth while I edit?

My preview window is set to Preview auto. Draft also had the same problem.

Thanks..I did a quick search but didn't find anything and I need to get this done today.

It is not uncompressed. It is a DV codec. I always have jittery video when playing from QT files. The best you can do is render it to a DV AVI. The quality hit will be minimal, but it will then play smooth.

You could also render it to HUFFYUV and not lose any quality.

thanks..I didn't think about that...sounds like an alternative...but what a headache because it means I need to render out 4 hours of footage..ouch.

AVI is just a wrapper. Ditto for QuickTime.

In my experience, when people say, "It's uncompressed," they often mean, "It hasn't been recompressed."
