Restoring old source footage. . .
Hey.
So a week or so back I posted this question . . .
“What’s the best way to treat damaged and pixelated footage?”
Some of you may remember it? I just wanted to re-post it because it went a little off topic, or at least I did, this happens whenever the word “Copyright” gets mentioned on one of my threads lol.
So my question this time is, whats the best way to clean up grainy footage? is it a case that it has to be treated frame by frame? is there anyway to capture a “noise template” in the same way that you can remove noise from an audio recording? or whats going on. .
Secondly, There is a lot of pixeled footage around, lot’s of people who would like to convert SD in to HD, why hasn’t anyone invented a plugin that can increase resolution? Surely it should be fairly straight forward no?, When you time stretch a section of footage your creating new pixels that wern’t there in the first plaice, this is also used in morphing, So . why can’t someone make a plugin that “Samples” each pixel, calculates and inserts new pixels using adjacent pixels as a reference?
Anyway, some tips one cleaning up grainy footage would be really helpfull, if anyone one know’s the “Propper” way to do this, I’d be very glad to hear from you.
Regards Richie.

There are 3rd party AE plugins that uprez SD to HD. CHeckout Red Giant’s site. Sorry but I can’t recall the name but it’s obvious once you see the name.
As for de-noising, I don’t have a recipe but AE does have a plugin to reduce grains.

As Roland mentioned there are plugins out there to do just that. Here is a partial list.
And I believe the tool to remove grain in AE is called remove grain. But I’m not sure. It takes a sample and removes the grain. It’s very powerful (which is code for BEWARE IT HAS LOTS OF SETTINGS).

When using Remove Grain, it does a pretty good job at the default settings. However:
– try enabling temporal filtering
– by default, the effect samples noise from the first frame of the clip, then removes that noise from the rest of the clip. If you don’t want to sample that frame, change the frame under the sampling tab. Tp see the frame, select “noise samples” in the viewing mode.
– for most situations, the Noise Reduction setting is the only other thing I change.
– to quickly see the effect on/off, take a snapshot without it, then toggle viewing the snapshot as you mess with the effect settings.It’s not a magic bullet, though. If the footage is too far gone, you may get softening.

Guy’s, that was most helpfull 😉
Awsome tips, thanks.

If you have posterization(where you see hard transitions of color saturation), smart blur set at (radius 100, threshold 15), works really well and doesn’t visually soften the image.
