Pixelation....please help!

Randy Brown wrote on 5/13/2005, 8:13 AM
I searched here and the Vegas forum but can't determine why I keep getting (approximately) one-frame pixelation about every one or two minutes. It shows up on my TV and in the preview for DVDA 2 but not in the AVI.
It's gotta be in the rendering process doesn't it?
I believe I have rendered all of the suggested ways. My last was using the (batch render) Main Concept MPEG2 customized to DVDA vieo stream 2 pass, 8 max, 7 avg, and 6 minimum but it renders random (different spots every time) pixelation. Please, if you have any ideas send them my way as I'm supposed to dupe 250 copies of this by Monday for a client.
TIA,
Randy

Are you saying that the entire frame is pixelated, or are you seeing what might be described as pixel "dropouts", where there are pixel-sized holes or pixels with random colors in a frame?

I had a problem with these occasional "missing pixels" a month or so ago. Fortunately, it started right away when I added a new hard drive & USB enclosure to my system. It turned out to be a problem with the USB enclosure. The hard drive functioned perfectly in a different, identical enclosure, and disappeared entirely when I sent the bad enclosure back for replacement.

This may or may not be related to your problem, but maybe you could try rendering to a different drive and see if it clears up.

Yes, this, but haven't noticed color just white and just a few (perhaps 5-15 tiny squares)
Should I try to render to another hard drive? I don't have a USB drive.
Thanks very much,
Randy

Honestly, my problem was so short-lived that I can't swear that the dropouts weren't white, but it seemed that there were colors.

Put it this way -- even though you don't have a USB drive, why not try an abbreviated render of the troublesome project to a different drive, anyway? You're facing a deadline, and you need to try SOMETHING while you're waiting for other suggestions to roll in.

Good luck!

Have you tried the avi into architect and render from there ? No techno reasoning involved ,just thought might be worth a try.

Well a different drive didn't help.

No but I'm willing to try anything at this point!!! Everybody says that's what you DON'T want to do but ...

Yep, but ya never know, also Randy maybe try some other avi videos and render to mpeg see if the same thing is going on, if not ,recapture the footage.

Good luck , and hope you make that deadline

That's just it Winrock there's nothing wrong with the footage (avi plays fine) and the pixelation happens randomly in different spots of different rendered AVIs.
I gotta go but I'll render the AVI in DVDA2 tomorrow morning.
Thanks,
Randy

DVDA 2's render was much better but there was still at least one frame that pixelated.
Here is one of the frames. At least on this one there is indeed color in there (notice the green on the cowboy's shirt on the left).
Thanks again,
Randy
