Ok, I re-edited an avi from my dvcam. Then I threw in transitions, slowed it down, and did a b/w filter. Rendered the sequence fine. Now, when I export it to a movie file (using the same pref's in setting's I've always used) it get's to about 530-550mb (movie file size) and just acts as if it has finished rendering and exporting the file. It doesn't freeze, or give me an error, just finishes, leaving me with an incomplete .avi movie file. I've done bigger movies, with more effects in them, and never have I had this problem. I've done a repair on it, checked high and low on websites for answers, even cleared all effects and tried again to render/export... all to no avail. My comp is ok, xp2000 procc., 512 ram, good vidcard... I just don't get why it's doing this, when I've done plenty other stuff with no problems... HELP ME PLEEEEEEEEASE!!!
