LUT filter keyframes

[Ric_Developer]

Hello everyone, as far I know LUT filter has no keyframe editing.
I would like change LUT effects intensity during playback.
Is there an alternative/workaround to do that ?
Thanks in advance.

A LUT is a static LookUp Table. In essence it is a mapping of the color of each pixel in your clip to another color via this table. There is no keyframing because there is nothing to keyframe. You can’t keyframe “turn colour #ABC into colour #XYZ” (although you can in HTML/CSS, but it probably isn’t what you want). You’ll have to apply a different (keyframeable) filter after applying the LUT instead (e.g. brightness).

There is a way. It involves adding 3 filters. The instructions are here:

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 …

You keyframe the Opacity filter.
