LUT Mixer for FCP X, Premiere Pro and After Effects

LUT Mixer is a colour grading plug-in for FCPX, Premiere Pro & AE that lets users combine and apply multiple LUTs with automatic skin tone protection and no loss in quality.
Working with LUTs (Look Up Tables) is popular and many apps and plug-ins support them. In most apps LUTs can only be applied one after the other. Since most LUTs are optimised to be applied to unmodified footage, it commonly happens that any LUT applied after the first one will not deliver the desired results since it is not applied to the original image but to one already altered by the first LUT.

With LUT Mixer, all LUTs can be increased up to a maximum intensity of 150%. In addition, 2 of the 5 possible LUTs can be applied negatively. Therefore, a LUT which warms up the image can also be used to cool down the look or an individual saturation LUT can also be used to desaturate the image. Skin tones have an important role in colour grading and there is a dedicated section to the skin tones to protect them from the tint of the LUTs and to adjust them separately if necessary.

Parallel Summing or Calculating the Average

For every loaded LUT, a selection switch can be used to determine whether it will be summed or applied as an average. All LUTs with their selection switch set to the sum icon will be added up. Colour shifts towards the same direction will add up while differing LUTs shifting the same colour in opposite directions will mutually weaken that colour.

Averaging-option Protects Against Overreaching

If several similar LUTs are loaded, summing them can result in colours that are too intense. The option “averaging” makes sure that users don’t have to adjust all LUTs if adjusting the intensity of one single LUT. When in averaging-mode, the intensity of all LUTs is not adjusted in absolutes. Their ratio is being calculated and then normalized to 100%. Therefore, the cumulative intensity within the averaging group plays no role anymore.

Since this mode also normalises very low values to 100% the averaging-group has a separate master control.

Features include:

  • Protection of skin tones from the influence of LUTs
  • Subsequently restoring and adjusting skin tones
  • Increase LUTs up to a maximum level of 150%
  • Applying LUTs negatively instead of only positively
  • Intuitive mixing of LUTs
  • Simple adjustment of professional looks
  • Standardised average calculation automatically adjusts the total intensity
  • Suitable for LUT-systems (separate LUTs for colourings and contrasts)
