Remove green color from 49 frames

[mlong30]

Hi All,

I just noticed that I have 49 frames of this shade of green in the video I'm trying to cleanup. Are there any solutions to clean this up? The fact that the crowd is jumping up and down and there is some zooming in/out going on makes this very difficult to come up with easy solution. There is also 74 good frames of the crowd jumping up and down.

I'd appreciate any solutions you can give.




Also whats the best way to copy a frame to another frame, or replace a bad frame with a good frame?

Thanks!

It appears to be all green.

There are small amounts of red and blue but that may only be random noise.

I can't believe the high school I purchased this from is charging $40.00 for this type of work! This is my cousins state basketball game, and I like to cleanup it up, to were it looks like its worth $40.00. They used DVDR recorder, and recorded directly off TV, with some cheap editing.

Hi-

You could greyscale it easily enough (or even tint it a different color), making the green section black and white. You could replace the 49 frames with 49 similar nearby frames easily enough, although I guess there would be slight (or maybe not-so-slight) jerks at the join points. You could replace the whole scene with another similar one of crowd reaction. Because there's so much movement, I don't think you can grab the colors from nearby frames, although that's easy when nothing is going on. To do these things, I'd use AviSynth, although it would mean removing the chapter this corruption is in and reencoding it, followed by replacing it in the DVD.

Maybe you can just cut out the 49 bad frames? It's less than 2 seconds of material. Of course, any audio will be interrupted. To do that, put the DVD on the hard drive, open the DVD in VobBlanker, and highlight the video in the upper screen to make it appear in the lower screen. Highlight it in the lower screen, hit the Cells button to the right, in the new screen find the cell the green part is in, and use the Prev/Cut button to remove it. OK back to the main screen and Process.

AviSynth's FreezeFrame command, although, again, it would mean reencoding:

The Trim command can be used to cut out the 49 frames, to be replaced with 49 good frames from somewhere else:

Greyscaling combined with Trim can turn the 49 green frames to grey:

We don't know what software you are using but with 72 good frames you have several options.

1. Loop (repeat) the good video frames.

2. Change the speed for the good frames 74/(74+49) = 60% or slower.

3. Old trick to fake multi-camera look:
Select 49 frames from the good 74, reverse them left to right. It will look like a different camera position.

4: Similar to #3, zoom in on 49 of the good 74 frames to fill the 49 frame hole.

Or any combination of the above.
