I realize that when one takes a compressed video format, like AVI, and re-renders it as another AVI, there will undoubtedly be some quality loss.
However, I'm wondering what settings might be ideal for preserving as much as possible a level of compression and quality that is equal to the original.
To be more specific, I have some AVI files from a digital video camera of some live performances. All I intend to do is combine them into one video, maybe with a fade in and out of black between them. The goal is just to archive the performances into one video clip.
The videos are 640x480, NTSC format.
In my initial experiments, the output video is noticeably more compressed than the original. Lots of JPEG-like artifacts and blocks.
Is there a way to get the output to closely approximate the input?
Thanks for any advice.
