Very Bad Renders - Please Help...

Please help me with this little drama;
I've rendered a small anim in Lightwave 8 as a series of TGAs. Take those onto the timeline in Vegas 5.
Looking at them in the Preview Window, all is well. Render it out and many bad things happen - in particular with the curtains. Please view my web little web site (an homage to this frustration) if you are curious about my woes and, more importantly, if you believe you know what I'm doing incorrectly - or what I can do to help this situation to .... not be a situation.

Man... Just when I think I'm nearing the end of a project, some little thing rears up and bites me on the head.

Hey buddy,

Unless my eyes are going...I don't really see a problem here. Looks fantastic to me. I may be either real easy to please or you're too hard on yourself. Let's see what the next guy says....

Could it be the DV compression you're noticing ? Try rendering it out as an uncompressed AVI and see where that takes ya.

But it still looks great to me.

Ditto Stan.

It looks truly marvellous. I've got some Moiré effects [ I think thta's what it is called - or is that edge-stepping with Pixels . . ] as the waving Curtain falls and if I wanted to do something there . . well maybe a very very tiny Gaussian blur . . .But I'm not convinced it isn't something to do with my LCD monitor - yeah? Do you see this on a CRT monitor too or TV?

I think you've done wonderfully well. How on Earth did you get that superb 3-D on the material and the falling curtains? Superb! TAKE A BOW! NOW!

Best regards,

Grazie

First, thanks very much for the kind words on the anim. That took this novice HOURS - no, days of experimenting in Lightwave 8's Cloth Dynamics. Someone else could have done it in less than half an hour, and now that I know my settings and went through all that trial and error, I could repeat it in about an hour. Both the marquee and the curtains are just medium density mesh with some specific motion attached to each. The results are fun.
If you're curious, I have the final MTO (Main Title Opener) up for my buddie's approval at www.matthewroddy.com/Erase/MTOAnims_OddnaughtBeat.wmv
I tried to cut to the beat, but in order to keep the little anims (segments) aproximately the same length, I had to occasionall cut on the mid-beat (for lack of a better word, since I'm no musician). The beat was written by the client in this project - the performer of the Flea Circus. This is obviously for a product we'll be selling in a few months on how to make your own flea circus (can be seen at flea-circus.com).
Now, as to the pixelation, I should have put up the DV render, I suppose (or at least a small segment of it). The pixelation is most evident when the curtains are in motion. But you're right, on my monitor here at work, the pixelation isn't nearly as evident as it was at home in the still. I didn't know it wouldn't show when I posted it last night. That's frustrating (that it didn't show up well). I have noticed a few things however; when I render the curtains alone, they don't get blocky. As soon as I composite them over the brickwall and marquee, they take a dive in quality. This also happens when I render in Boris Red, strangely. Now, when I render it with a substancial amount of Film Grain and efx, the problem is hidden to my satisfaction (as seen in the WMV mentioned above).
So, I apologize for posting a web site that didn't clearly define the problem and thank you once again for checking it out and the vote of confidence.
AZEdit, I will definately make sure I try your suggestions. I've never rendered in Square pixels before and will try that next. Thanks very much.

If your final output is dv. The banding will not go away. It is a limitation in color space.
