Feature request to patch dropped (black) frames

I already submitted this as a feature request, but I wanted to see what you all think

A filter that can be applied to the video as a 'dropped frames interpolator'. I often have mpeg-2 source that have dropped frames which show up as black frames.

If there was a way to select a time range and apply this filter to it, then vv could scan through, look for frames that are 100% black (or cross some threshold), and then interpolate the missing frames by gradually blending the frame prior to the drop outs with the frame after the drop outs.

So if:

f regular frame
A frame pre drop outs
d dropped frame
B frame after drop outs

source: ffffAdddBfff
filtered: fffA123Bfff

where

1 = 75%A 25%B
2 = 50%A 50%B
3 = 25%A 75%B

ANyone else have any use for this?

I would LOVE such a thing. I find quite a lot of these black areas, which appear to be ONE field out of a frame, usually, but only AFTER I have edited and render. They seldom show up while editing.

I use Quantizise to Frame, to help eliminate them, but the still show up, maybe 5 percent of my clips show them. One lousy black field can ruin a render.

Should a filter not be in the offing, how about a way to press a single button and have the cursor jump to the first field of every clip. That would find all of them manually. It would also be a fantastic way to navigate. Perhaps a backward jump, also.

Ctrl-Alt-Left/Right-Arrow will jump backwards & forwards to each "edit point": first frame & last frame of an event, beginning & end of fades/crossfades, etc.

Chien, I have LOOKED for those shortcuts, but missed them. Thanks.
