Pixilation

I put this on a seperate thread in case it got lost in the other post.

I am doing a long render, for the second time, and I noticed when I rendered it previously, there was some pixilation on some of the shots where the camera was moving. I put that down to the fact that I decreased the frame size so it fitted into the safe area, using pan crop. Hence the rerender.

If this wasn't it, does anyone have any ideas? The footage looks fine on the tape, and on previous renders where I put some basic footage originally, there's no pixilation evident.

Any hints would be appreciated.

Andy

Andy,
Can you put up a still or a couple shots? Based on your description, it sounds like motion blur gone awry. If you have it on the timeline/preview/render, then it's in the original media from the camera. The only way Vegas can pixelate anything is if you are changing media properties with a filter, trackmotion, pan/crop, and since you've done that...the other thing I wonder about is if you are off by a field due to your pan/crop, and this could cause interlace issues resulting in what looks to be pixelated.

Updating.

After tweaking the project, including fixing the pan-crop mistake mentioned in another post, the render dropped from 40hrs to about 15hrs, on my 2.6 celeron machine.

The pixilation mentioned was gone, so obviously the pan from full screen to half screen over the space of an hour was causing the pixelation.

Thanks for the advice SPOT, your help and my persistance paid off! Another part of the learning curve!
