Rendering problems

Hi guys

I'm with problems to render my video. The result is good, if I don't have moviment in my videos... not extreme moviments like a F-1 racing, just people waving. When I watch the .avi directly from my camcorder (GS200PAL) to my TV set, or even in my PC, the scenes are perfect. After the rendering process from avi to mpeg I can notice a "pixel" efect in my PC. In my TV set this efect is worse. I've tried some rendering options and the NTSC seems to be the best to minimize the efects in the moviments. I've heard that could be a field order problem and I've tried to change from bottom field to upper field first but the result in PAL is always bad. It seems that when I convert to NTSC something is going to be fixed. Unhappily I don't have any clue that it could be. I'd like to keep the PAL. I'm rendering with Vegas 5. Just in case I've tried to render with TMPGEnc but the result is pretty much the same. I put some sample files at http://geocities.yahoo.com.br/jubistraus/ If a good soul could help me I'll be gratefull forever.

Wrong field order will give what I would describe as jerky motion with movement, rather than pixelated.

What the field order is isn't particularly important, what is important is that it is labelled correctly at all stages so that your software doesn't do the wrong thing with it.

DV capture from camcorder should be lower field first.
Analogue capture will be dependent on the capture device.

If it was captured as lower field first, you need to ensure that this is what the editing software is seeing it labelled as & what the MPEG encoder is informed it is as source when it comes to encoding.

Hi again,

If I check the properties file Vega informs lower field. I've captured from my camcorder with Vega. Could my camcorder be an upper field and Vega misunderstand this information? I didn't find any specific information about my cam (NV-GS200) just that DV should be lower field. If I understand its doesn't matter if you keep the same information in capture and edition. Just in case, I've captured the file with the WMM2 but I didn't see any difference. Unhappilly WMM2 doesn't bring any information about field order. Anyway, as I said, I've tried to render with lower and upperfield options and both of them are really noise (jerky, pixelated, the files are at http://geocities.yahoo.com.br/jubistraus/index.html for impressions) in PAL. In NTSC the result is better but far from good. Is there any other thing that could I check? I'd like to thank you very much for all help.

Try taking a small sample of your .avi file , change how it is labelled in properties to opposite field order (ie upper field if it's currently labelled as lower). Then render it to MPEG & look at the results, does it make any difference ?

I've already tried this. I think the result is worse than before. I put the file in http://br.geocities.com/jubistraus/sample_pal_upper.mpg

Very good link. I think that I have a very unusual problem. I've passed all the steps at "Classification High Resolution Video" in the page http://neuron2.net/LVG/classifyhighres.html and I've tried all filters with VirtualDub and none of them seems to correct my video. I think it's better start a thread in a more specific forum.
