AviSynth - RemoveDirtMC/DepanStabilize

[Dr.Who]

They chose to release a damaged-poor quality VHS (restored by an unknown company that did a horrible job) despite having 35mm films in the archive.

They probably don't have film of that concert

35mm would be uncommon for concert footage. I heard that some of the concerts (Wembly ?) might have been shot on 35mm , but most from those years (?90's) would have been betacam footage

Youtube doesn't do much justice and doesn't necessarily indicate much . For example, that 2nd link looks like upscaled HD. You can see deinterlacing artifacts .

Second is upscaled HD. It's done by amateurs fans that try to restore the footage. I've been in `this` for quite some time and most of them don't know how and what to do. Now I'm trying to be more serious regarding this matter.

So is there anything you can tell me regarding the footage that I showed you earlier apart from the gradulation curves? Or should I leave it this way? I have a friend that improves the audio in a studio, so we want to make a perfect combo for this.

RE: color - a lot of it is subjective. You make it the way you want it to look, keeping in mind some of the lighting is colored, and might change by scene. (Things aren't supposed to be netural or balanced under colored stage lighting) . For example, in "2.vob", at the end is a cut to a crowd shot , notice the lighting is much different there. You can't expect to apply the same filters there. It's more difficult to do in something like vdub/avisynth, easier to do in other programs where you can dynamically change adjustments with keyframes . (Yes you have limited control with curve editor in vdub, but the amount of control is a lot less)

Some things everybody will agree on, for example it definitely doesn't look right that MJ is glowing blue in some shots - that's from the blue channel imbalance with overbrights . You can affect certain hue ranges with selective color correction , or "secondary color correction". For example , you might want to only affect those "blue glows", bring them down a tad , but leave everything else. It's also possible in avisynth with Tweak using starthue, endhue, but the control isn't as good as in other programs. (The mask generated in avisynth isn't as refined or accurate)

Other things are more subjective e.g. skin tones - some adjustments might make his skin too "green", or too "blue". It's difficult to satisfy everyone. For complex fixing, you actually need masks, roto, motion tracking as well to make things "perfect" (e.g. davinci resolve, after effects, nuke) . Resolve is really the "gold standard" for professional color work. There is a free version of Resolve, but it's limited to 2 nodes

But if you have something to go by (a guide comparison or "benchmark" e.g. some shots or even concert photos from a released higher quality version) , then it's easier to do . A lot of the adjustments are non linear (you can't use only levels type adjustments) , hence the suggestion to go with curves for at least for part of the workflow



RE: ghosts/halos - the only way that you can do a good job is the way I mentioned earlier (rotoscoping/motion tracking/ masks/compositing) . There is no concievable way you can do that in avisynth/vdub only with this footage, and expect to do a good job of it.


It boils down to how much time and effort you want to spend on this
