Uncompressed AVI files are large, and difficult for video editing programs. The solution is simple import de exported avi file into your video program and export that file as AVI, you will see the file is 1/10 of the original and once imported into your video program again, it will run smouthly, every program can handle now this kind of AVI file. Good Luck!

BluffTitler can create compressed video files. To do that select the COMPRESSED AVI radio button in the FILE / EXPORT AS MOVIE dialog.

I've did some testing with various codecs. I've used a short video with lots of whitespace so that it can be compressed very well. Here are the results:

-Uncompressed: 66 MB (100%)
-DivX: 197 KB (0.3%)
-Microsoft MPEG-4 Video Codec V2: 268KB (0.4%)
-Huffyuv V2.1.1 (lossless): 17 MB ( 25%)
-Cinepak Codec by Radius: 930 KB (1.4%)
-Microsoft Video 1 (very old codec): 969 KB (1.5%)

As you can see the compression rate is very different, but so are the image qualities. Except for the Huffyuv codec which looks as good as the uncompressed file because it's a lossless codec. Lossy video compression is always a compromise between file size and image quality.

I'd like to stress the fact that if a video doesn't play smooth in your NLE it does NOT mean that it won't play smooth on the DVD it will create.

This totally depends on the DVD export options of your NLE and the quality of your DVD player and never on the original video file.

For maximum quality in the end-product (DVD, streaming video or video file) it's best to postpone compression until the very end. For this reason I do all my editing with uncompressed files.

Here's another tip:

Since video files take up a lot of diskspace, heavy video editing can dramatically reduce the lifespan of your harddisk.

I advise you to place your vides files on a secondary harddisk and not on your boot drive (normally this is your c: drive). If a secondary harddisk crashes you can easily replace it with a new one. A crashed c: drive is a totally different story.
