Sequence Render Problem

I rendered an animation as a series of Jpeg photos, then compiled them into a movie (avi-Jpeg format). They played with windows media player just fine for awhile, then abruptly went black. They still take up hard drive space, and they still play, there’s just nothing there. However, not all my videos did that. Only the ones I rendered in widescreen. It makes no sense to me.

Any idea what might be the problem? I’m literally pulling out my hair!

Have you tried playing them through another player? VLC perhaps?

I imported the files into a movie making software. Same story. I don’t have another player.
