I need some help! Im creating projects with .avi files from my Canon Powershot digital camera...apparently the files are saved in mjpeg format, and i needed an mjpeg codec to load them into Vegas. I downloaded one and the files loaded into vegas fine, but now when I goto render them to wmv or rm to publish on the web, they are the correct brightness for about 3 seconds, then they become significantly darker for the rest of the video. I cant figure out what setting will fix this, either in the rendering options of vegas or of the codec...does anyone have an idea as to what type of setting could fix this??? thank you!!

you *might* be seeing an effect of your video card. some video cards don't handle directX overlays right, and they'll play a video bright and sharp for a few seconds, then screw it all up. most of the time it gets darker, and a sometimes becomes blurry.

I've seen this happen countless times in Windows Media Player, but it doesn't happen on any of my current PC's (all have NVidia cards). I had an ATI card in here for a while (Radeon 8500) and it was the worst. videos played perfectly for a second, then snapped into super blurry mode, but *ONLY WITH CERTAIN SIZED VIDEOS*.

if you can, try the videos on another PC to see if this still happens. or try turning off your display accelleration and play the videos. depending on your OS you'll find a 'Troubleshooting' slider somewhere and if you turn it down 3 notches I think? it will turn off DirectX.

soplame311:

I have a Canon PowerShot S110, and have no problem reading the videos it creates in Vegas Video. I think it's my computer, a Sony VAIO tower, that is decoding the M-JPEG frames, because Vegas identifies the clips as "Sony MJPG software CODEC." I don't think I even installed much of the Canon software.

When you play the video in Vegas, does it have the same problems? If so, it's a problem with the source clips, or with the codec.

If it only happens on render, there's something else going on. Try different render formats / templates and let us know if it's the same or different.

P.S. Vegas saved the day when I realized (after the fact) that it's a bad idea to shoot video with the camera rotated, like you get used to doing for stills. When I first watched the clips by hooking the camera to the TV, everyone had to turn their heads to see the cool waterfall in the Jeep area of the Chicago auto show. With Vegas, I used pan/crop to rotate that section, pillarboxed it, and now I even have "increased resolution" for the area of interest (the waterfall was taller than wide).
