The problem is this will not remove scratches and burn marks as they will be the same on every capture, theoretically a mean filter would be the best for removing analogue noise as it is a completely random effect, however the median filter would be advantageous in removing dot crawl, and the effects of laser rot which may not be the same on every capture.

I realize it wouldn't do anything at all to scratches and burn marks, but those are really separate problems anyway. Laser rot and analog noise are certainly the main focus.

My intention here was to test how effective these Photoshop filters might be when used to combine multiple captures. My samples above were just a quick and easy method to demonstrate what might be possible.

In reality, well, the results aren't as impressive. Tonight I took my trusty LD-V8000 and made 11 captures of the binary sunset shot (from the Faces LD), cropped, IVTC'd, etc. etc., and exported the same frame from each capture into Photoshop. Here is a sample screencap of the raw capture:

...and here is the output of all 11 aligned and median stacked:

Not much difference, unfortunately. If I can figure out an easier way than importing the frames into Photoshop, applying the filter, then saving as a new file, I may try to do a few seconds of video to see if there's a more noticeable difference in motion.
