Cleanup DV footage with color bleeding

[LSchafroth]

I have a lot of High School football footage for a college.

The lighting for their field is axcellent and the only real problem I have with the footage is the color bleeding in white areas. They have black uniforms and white numbers on their jerseys.

The white shows up as a green or pruple color most of the time and appears to flicker on occasion. Is there a filter I can use to remove this?

I use VirtualDub and AviSynth.

Colormill is a great color correction tool for virtualdub (and can be called via avisynth). Pretty easy to set up, and very flexible.

I am already using colormill. The colors for the whole video are perfect now, except where the white lines are on the field and the lettering of their clothes. The lines on the field look like a flowing rainbow.

PS I applied the TV filter with avg temperal soften and it reduced it some.

Here is the source without any filters. I cropped out the center of the image.

How are you capturing from your DV camcorder?
That looks like an NTSC problem.

The only thing you probably can do is reduce the saturation for software or hardware solution Color Corrector ...you can tweet it yourself but you need a good one like vidicraft etc

This is footage taken directly off teh DV camera to the PC via Firewire and WinDV.

Someone else did it for me, so maybe his camera is junk.

I have it cleaned up oretty well now using the TV filter. Now I just need to get the colors a little better.

Thanks!

I spoke with someone else on the football team and found out they are using a 8mm camera and transferring it via capture card.

Thats a little different then a DV hugh?

Anyone know how to create a split screen with the left showing the original and the right the filtered output? They wand to see the side by side comparison.

FFt3dfilter in avisynth will do it.

fft3dfilter(plane=1,sigma=20)
fft3dfilter(plane=2,sigma=20)


and to do a comparison

a=avisource("yourfile.avi")
b=avisource("yourfile.avi").fft3dfilter(plane=1,si gma=20).fft3dfilter(plane=2,sigma=20)

stackhorizontal(a,b)

-or-

a=avisource("your_unfiltered_source.avi")
b=avisource("whatever_you_created_with_Vdub.avi")

stackhorizontal(a,b)

Yes. I was going to say it looked like 8mm. It also might be a second generation dub of a Video8.

The colors come from NTSC decoding. Luminance noise is being detected as 3.58MHz subcarrier. If the original is Video8, recapture from a Hi8 camcorder (S-Video) or Digital8 direct playback to DV format will eliminate the false color.

As it is, it appears it can be detected when Y is high and Cb or Cr are also high. This is unnatural and thus can be filtered out.

Thanks everyone. I was able to filter it out quite well.

I created a split screen with AVIsynth and they are reviewing it.

Thanks!

If it was 8mm, what capture card was used. Furthermore, did they use s-video or composite because the rainbow colors on the white looks like composite quality.
You said at first they used a firewire imput. This obviously cannot be for an analog camera. Unless they hooked up the 8mm to a miniDV and then transferred that through firewire to the computer. Could you clarify that with them?
One other thing, are you just using this video to send to colleges so that they might take a look at one of the players? Or do you want to use the footage for a team video that you want to save? Because if it's only to send away, the colleges won't care if the video quality is top notch.
