Unfortunately, I don't. I'm interested in a related problem, though. My camcorder has developed a bad pixel, where the red channel either has hypergain or is stuck on. I would like to remove that pixel from my video. One way to do that would be to characterize the pixel by using a white and dark background, making a mask, and subtracting that mask image from each frame. This would leave a dark spot, but those typically blend in better. Is there an easy way to subtract a reference frame from all other frames in the video? A better way would be to fill in the pixel with a value derived from its nearest neighbors based on the mask. Does something like this already exist, or would I need to figure out how to write a filter? Any ideas are appreciated. _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
