video quality going down...

hi guys.
Been working on a music video for this band. We captured the video off the camcorder, and then started doing things to it in after effects. Every time we did some editing or added something, we exported the video and then imported the new vid to do more things on top of it.
Thing is that at some point we realised that through the exports (as .mov, best quality, losless) the last vids have lost much of the quality they had when they had been captured. And I can't understand why. I haven't compressed them or anything. Should I export as something else apart from quicktime movies?
Thanks.

If you're working on an uncompressed system, for best quality, I've always exported frames. Of coursem, I'm an animator, so 30,000 frames don't scare me none. since you don't have sound to sync up w/ presumably, you'll be ok with this tech.
Maybe I'm a goober though.

you must be compressing it along the line somewhere.
do you really need to keep exporting and reimporting it?

I don't think I'm compressing it. The default ('losless'), is not really compressing, is it?
Maybe I don't REALLY need to keep exporting, it's just that the machine is working faster with footage than 'pre-compositions'.
Tommy, when you export images, do you export as BMPs?

I actually use Targa because it can retain alpha info if needed. An NTSC frame is about 1.35 mg, so plan accordingly. Fast HD is needed in AE SATA works better than most..

even with lossless there's some form of enconding goin on, and hence compression. Over time the reduction in quality will become more marked.
Figure out a better workflow.

use pre-composing and nesting rather than exporting and reimporting.

yeah, you are probably right. Thanks for that!
