Possible to use avisynth to eliminate dead pixels on video?

Hi there,

I have a digital video camera, and unfortunately it now has ONE dead pixel on the CCD. This results in an always white pixel on any video I have recorded. Depending on the scene, it can be very distracting.

It would in fact be easy to fix this. All I need is software where you can specify the location of the dead pixel, and it will then change its colour to that of the average of the surrounding pixels. I am sure that this would completely eliminate the problem in almost all (if not completely all) situations.

Question 1:

Would avisynth be able to do this? I have not used avisynth before but someone on usenet suggested it might be able to.

Question 2:

If so, would someone who is familiar with avisynth be able to write the appropriate script or whatever is required (assuming it is a two-minute job once you are familiar with the program)?

I think that such a program would be useful for quite a few people - when I posted this question on usenet a couple of other people said they had the same problem, and it would be better to find a software solution rather than throwing away a camera that cost thousands of dollars.


Thanks,

Mark
