I just updated my video drivers, nuendo to 5.5 and quicktime.
This did not resolve my problem.
Problem is that I drag a short (2-3 sec) AVI or MOV file into Nuendo and press play - the video output doesn’t animate and is frozen on the first frame.
If I scrub, I see the image move, but if I press play, nothing happens.
The odd thing is that we’ve tested the same video file on another machine with Nuendo 5 and it works fine.
As said, please state your Os info, graphics card etc.
One tip: If you are on WinXP, there is a problem in XP with OpenGL on other than the primary monitor. If you have the video on the second monitor in Xp, try moving it to the primary, test again.
