Add keyframes to hue/lightness/saturation filter

[ejmillan]

Here is a new use for what is explained at this link

LUTs Specific

The creator of the LUT or a LUT editor can adjust the intensity, but a LUT captures the state of all color and level changes. They are not inherently adjustable. If other tools do allow you to adjust the intensity, they are modifying the LUT in a simplistic manner. You can reduce the intensity of a LUT or any other filter using filters in this order Mask: Simple Shape with Width and Height = 100% Opacity (here is where you adjust intensity including keframes) LUT (or other filters) Mask: Apply …

Then @Austin recommended a solution based on the above to apply to the white balance filter.

White balance and LUT3D

Here’s the template for an idea: …except instead of having LUT as the third filter, put in White Balance. Force the white balance to be an extreme value. If your video generally needs to shift towards yellow, then go extreme yellow. Same if in the blue direction. Then, keyframe the Opacity filter to dial in the amount of white balance that’s needed. The extreme white balance setting gives you some buffer to work in. I haven’t tested this to work. I’m mobile and making a guess.

We can then use some filters that do not incorporate keyframes and control them by keyframes through opacity.
In your particular case, you replace point 3 in the following list (LUT) with hue/lightness/saturation and it works like this.

1. Mask: Simple Shape with Width and Height = 100%
2. Opacity (here is where you adjust intensity including keframes)
3. LUT (or other filters)
4. Mask: Apply

I adjusted the filter with the following values:
hue (200%) lightness (200%) saturation (0%)
The mask is set to the simple shape, add, width, and height 100%.
