Hi

Isn't it just when you look at it on a computer monitor that you notice this shakiness? Computer monitors normally updates at 60hz and that doesn't really mix with 29.97fps that you have or not at all with 25fps like we use here in Europe. 
If i want to check motion i always use a videomonitor connected to a SDI videoutput.

That's good to know. I'll definitely try that out.

In this case, I just answered my own question by taking it into FCP7 and running it through my Matrox MXO2 LE. Rock solid and looks great. All of the shakiness I see in QT player (and to a lesser extent in AE) went away.

Not sure why this is so since FCP is based on QT as well.

Thanks,

James
