Hi Logik pros!
I’m looking for a way to fix subtle shifts in color across long shots for old films. Across a minute long clip the color gradually shifts to a yellowish hue and then back. It’s subtle and hard to see unless you A/B against frames from the beginning of the clip compared to the middle of the shift. Hoping someone can point me to the best tool for something like this, and or a “how to” video of how to tackle.
Thank you much, Cheers,
-Chris
I have no clue if there is a tool for this, but here’s where I’d start:
Use the Logik Matchbox “Y_Sample” and have it output a consistent color. Stabilize the image so that it’s always sampling an area that’s the right color.
Subtract that sampled color from the plate, then add back a static frame of it when it’s the right color.
Sapphire’s flicker match may address this too, but I haven’t used it in a while. Possibly also worth looking at Ivar’s “crok_newbalance” which auto-white balances stuff.
If the content stays relatively the same across the the length of the shot, Match Grade in NukeX might work. I haven’t tried it but somebody created an OFX that I think does the same thing in Flame. Search the forum for Match Grade and you should find it
Is it a flickering change in colour or just a gradual shift?
have you explored any of the dedicated tools for issues like this? PFClean, DRS Nova & Phoenix are three that come to mind. Having done a bit of film restoration I have to say that the tools designed for the job do make life easier, but you do need to factor in the time to learn them.
Diamanté is another.
Thank you much Andy! Ivar’s crok_newbalance ended up doing the trick - thank you!
Interesting Angus, thank you I’ll give it a whirl!
Thank you Greg, they’ve promised they have a nukex license but haven’t gotten it up and working yet. I look forward to trying this out when I get a chance.
Thank you Adam, I know they have Nova & Phoenix in a nearby bay, I’ll see if I can sneak in to play with those sometime.
