VirtualVCR: Best Color Format for capture?

[kisk]

I'm a laymen when it comes to color formats. I'm capturing ntsc television with the HuffYUV 0.2.2 codec @ 640x480. The Huffy settings are set to: Field threshold = 240; YUY2 Compression meth = Predict median(best); RGB Compression meth = Predict grandient(best);

Now I plan on converting my vids to deinterlaced divx and play them back on a tv thru a standalone divx player.

My question is, does virtualvcr's color format video setting make any kind of difference in the quality I will end up with based on the info I gave above? Under what circumstances would I want to change the color formats? The choices I have are RGB24, RGB555, YUY2, and YVU9. I'm currently using RBG24. I'm trying to get top quality captures and anything I can do to increase the final product would be nice

Thx,

If I'm not mistaken the DivX/Xvid formats use YUV or aka YUY2 color space. So you want to capture YUV/YUY2 as opposed to RGB.

Also I think it depends on the video capture card you are using BUT I've heard that capturing 704x480 and then resizing to 640x480 will both look better and give you a more proper aspect ratio than a direct capture to 640x480

Yes I was told that most cards natively capture in YUY2 so me capturing in RBG was doing unnessissary conversions and taking up much more disk space. I switched to capture in YUY2 -- I can't tell a difference in color/quality, but it uses ~42% less disk space than the RGB.

I also tried that 704x480 capture but when I resized (bicubic) back to 640x480 the color was way off. Any idea why?

Try LanczosResize method instead of BiCubic

Example:

LanczosResize(640,480)

Actually I figured out what the problem was. The video was interlaced and I was resizing and deinterlacing at the same time. I tried again later while keeping it interlaced and it resized just fine. Not sure why it did that but oh well. Thanks again for all your help
