Fixing Constantly Changing White Balance

[Jaeson Jrakman]

Oops, just saw your pre-comp instructions.

[Jaeson Jrakman]

I’m’ going through this now, and I’m not understanding “the shadow/highlight code upgraded to include b/w you’d paste into Shadow Amount under effect ‘Shadow/Highlight’ under layer ‘8mm ships.mov 2’ in comp ‘Final output’.” Does this mean that I add something to the Shadow/Highlight layer to accommodate black and white? If so, how? I don’t see R, G or B where I would paste the formulas into.

When you say, “the new hue precomp uses an adjustment layer set to hue for effect-hue. you can also add curves set to color, and curves set to luma for flat images.” Does that mean that I add an adjustment layer to this comp, and then add the hue/saturation effect, the curves effect? If so, what settings do I put in them? How do I set hue for effect? How do I set curves to color? How do I set to luma for flat images? I’m not seeing controls in these effects for these settings.

I copied and pasted the formula into the Shadow/Highlight layer, and this error message popped up:

alt+click stopwatch. paste in code.
you could add an effect curves, set the adjustment layers to color or hue or luma will make the curves only affect one thing at a time.
i don’t think it matter if you put it in a hue precomp or the final output comp as an adjustment layer.

I did come up with a large upgrade. This version will find the black white balance and white output white balance so you don’t have as much grading to do in premiere. It fixed all the skin too. paste these in the rebel cc levels.

duplicate the 8mm ship and put the copy above the original. set the mode to ‘color’

red input black

effect(“Step 1: Set Black”)(“ADBE Color Control-0001”)[0]/50-effect(“Shadow Brightness”)(“ADBE Slider Control-0001”)

green input black

effect(“Step 1: Set Black”)(“ADBE Color Control-0001”)[1]/50-effect(“Shadow Brightness”)(“ADBE Slider Control-0001”)

blue input black
effect(“Step 1: Set Black”)(“ADBE Color Control-0001”)[2]/50-effect(“Shadow Brightness”)(“ADBE Slider Control-0001”)

Thanks again for your response, I’m just getting back to this tonight.

So I alt+clicked the stopwatch on Shadow Amount under Shadow/Highlight in the 8mm footage, pasted in the code you wrote above, and I get this error message:

“you could add an effect curves, set the adjustment layers to color or hue or luma will make the curves only affect one thing at a time.”

So the problem when I create the hue comp, and then add the adjustment layer, I add the Hue/Saturation and Curves effects, but don’t really know what to do with those effects. Just adding them doesn’t seem to do much of anything. And I don’t see how to set the adjustment layer to color, or hue, or luma. Do you mean set the mode of the adjustment layer to color, hue, stencil luma, or silhouette luma?

I’m still not sure what this means, “an adjustment layer set to hue for effect-hue.” Do you mean set the mode of the adjustment layer with the curves effect to hue so that the curves effect only affects the hue? How do I set the curve effect?

Here’s what I have so far:

Does that look correct?

I appreciate the AE CC 2017 upgrade file. But unfortunately, I can’t do anything with it because I’m running CS6, and CS6 won’t open AE CC 2017 files.

I have decided its easier to just export as an older version than piecemeal the updated code. To that end, I saved all my latest updates as an older CS6 version which should be compatible with your CS6.

AE -CS6 remove flicker and fix auto white balance in 3d points.

I honestly can’t thank you enough. I’ll give that a shot tomorrow. Thanks again!

So I’m rendering this out now. I’ve got about a 2 hour render time, so I probably won’t post on this again tonight.

There was only one small glitch. For some reason, when I replaced the footage the width seemed scrunched, so that there were black bars on either side of the screen. This was easy enough to fix by stretching the width scale to 110. I checked the aspect ration of the project, and it was set to 1920 x 1080. I checked the details in the properties of the footage, and it too was set at 1920 x 1080. So not sure what happened, but it looks right when I stretch it out like that. I was able to deal with that but thought I’d put that in here for future reference for others.

But mainly I wanted to make a point of thanking you again. Thanks!

[Chris Wright]

pixel aspect ratio was 0.91 from old NTSC SD and lower fields were on. glad you find it useful. i’m working on prototyping an autograder that sets the black point, white point, gamma, saturation. this code here I will use for the 3d white pointing.

[Jaeson Jrakman]

So it just got done rendering out. There’s still a slight variation in color in the white background, it fluctuates between a cool white and a warm yellowish white.

But overall, holy smokes what an improvement! Obviously, it’s good advice to use the correct camera settings and create good footage from the start. But those who say bad footage can’t be improved haven’t seen this work. Incredible!

Thanks!

[Jaeson Jrakman]

I wonder what would happen if I ran my rendered footage through this again?
