Why is Vegas rendering just drizzled videos?

[Clever Sleazoid]

I am editing a big number of parts of videos in one single project. All the files are encoded as the same exact mjpeg. Today I could render it properly, but I found a little mistake at one part. So I fixed it (it wasn't anything complex), but I didn't have time to render it, so I postponed and rendered it just now.

Now I tried to render the video a lot of times, but the image just looks like an old broken TV: https://forum.videohelp.com/images/imgfiles/WSuDROW.jpg

What could be happening?

Is the whole video like that?

Does it look like that in the preview before exporting?

What format did you export, and what settings? Did you try something else ?

How are you playing back the export? Did you try another player? (is it a playback problem)?

Did you try disabling GPU acceleration?
