I made a fully automatic white balance after effects project. it uses part of rebel cc then finds the color cast and automatically removes it. it also fixes cameras with auto white balance on changing too much in a shot.
if you’d like to see how well it works, apply rebel cc to test_wb comp and apply wiggle(1,.2) to set grey. The white balance will go absolutely bananas, but the final comp will still work perfect. Which makes you wonder, why didn’t adobe make this plugin 10 years ago?
I continue to be impressed with the clever solutions you come up with to solve what seems like the very problem I am currently working with.
This one works amazingly well. I have to admit, I am having a bit of difficulty understanding exactly HOW it works. I am guessing there is some expression that refers to the ‘gg’ comp, but I haven’t found it yet.
In any case thanks for another great solution.
Any chance you could add a tool to even out the exposure variations as the camera’s auto exposure tries to track changing light levels?
it simply imagesamples the whole image, averages all the pixels and returns a 15% grey that gets put into a log lin function in the grey point. I’m currently working on an auto exposure. In the meantime, ae’s color stabilizer in the past worked great for me.
also, I wrote a mouse program that moves farther the faster you twitch your wrist. It saves me from carpel tunnel.
I added an auto exposure in midtones brightness. It’s beta, but seems to work good. I am going to add frame smoothing to it after I figure out easing. until then, perhaps convert to keyframes and easy ease.
Definitely would benefit from some frame-smoothing. I tried it on some old VHS footage (shot in low light with an old camcorder, so the footage was …uhm, well, …junk!)
I would sometimes see frames that flashed or had significant color difference from the rest. My guess is this is due to noise in the video. You might want to try blurring the layer that is used for the ‘averaging.’
It is certainly going to save me a lot of time/effort. I’ll have a bit more time this weekend to really try this out and let you know what else I discover.
