Filter or utility for removing Hi8 dropouts?
I've just bought a DVD-burner and one of the projects I have is copying many, many Hi8 tapes onto DVD. Over the years in this forum I've lamented several times the problem of dropouts in Hi8 footage. (Please don't confuse this with dropped frames.) Dropouts in Hi8 footage appear as blips which shoot across the screen covering one or two scanlines in a frame or two of video. They happen quickly, but in certain situations they can be very distracting, especially when you've been made aware of them!
Thanks to Prospero (who's hosting these images), I'm able to post images here which show what a dropout can look like. I've added two white lines to the images and the dropout appears half-way between them stretching across the entire width of the images.
This first image is full frame.
This is the same frame cropped closer.
My question - Is there a filter, utility, or process available that can automatically remove these dropouts? I'm not too familiar with VirtualDub, but I believe there are filters it uses which can correct certain imperfections when it senses illogical differences between adjacent frames of video. "Illogical differences" may not be the best phrase, but I'm hoping some utility exists which could repair these corrupted video scanlines, possibly by replacing them with the appropriate pixels from the previous (or following) frame of video. Ideas anyone?
