I've noticed that when I import an uncompressed .avi file, and then render it with no effects at all, again as an uncompressed .avi file, there is a small loss in quality. Some of the sharpness and brightness is lost from the image.

Surely rendering a clip without any effects and any compression should create a carbon copy of the original clip?

The reason I ask is that I noticed a clip with some garbage matting seemed to not quite match up (in terms of quality) to the original footage. I want to make sure the footage I am chromanating (is that a word?!) is as good a quality as the source file - I hope to project this on a big screen in a couple of months!!

Any thoughts??

Cheers,

I'm not sure, but you might want to check that you've got the project and render settings all correct.

You set up the project settings when you start the project - and to check that you're rendering in high quality, go to Render > Render Settings > and check that the format box says "Uncompressed AVI", and that "High Quality Render" is selected for the Render Engine.

I've not personally experienced this problem - so that's the only thing that I can think of, off the top of my head.

If I think of anything else, I'll post again.

Hope this helps,
Arktic.

The quality of your footage should not degrade (i.e. it shouldn't get blurry). But malone has done some tests and noticed you are correct that colour values are shifting very slightly using the high quality render. We'll get on making a fix for this ASAP.

Thanks guys,
The Render Settings were set to uncompressed and high.
Perhaps the slight colour shift is, to my untrained eye, what I'm calling blurry. A fix would be great - thanks schwar!!
