LUT intensity (or opacity/strength)

The possibility to apply 3D LUT is really great, but 3D LUT files are often too strong. If it’s possible to add an intensity (or strength / opacity) cursor for LUT, the 3D lut function would be amazing and more usable.

Thanks a lot for your work !

This will not possible because the change really belongs in the LUT itself, and also the core filter logic comes from a FFmpeg library. You can put a clip with LUT on a track above another clip with the same clip and then use opacity to blend the filtered clip with the original.

A LUT merely lists the output RGB triplet for a given input triplet.

You would need a new LUT for less saturation change and some method of storing an alpha for opacity.

One method for controlling the intensity of a LUT is to apply 4 filters:

1 Mask Simple shape (change the size and shape to the max)
2.An opacity filter
3 The LUT filter
4 Mask Apply filter

Change the opacity slider of filter #2 to change the intensity of your LUT

I don’t know if it is possible to save this combination as a preset but it would my life a lot simpler having to not add 4 filters in each time (i,e, having multiple filters in a preset)

Shotcut - New Version 23.05 added Filter Sets. Have you tried it?

Yes of course how silly of me… I went from 22.12 to 23.07 without reading the changelog.
Great work.
