Check your look before you trust it. The Lab in the cinemaOS Grade room shows a LUT as a three-dimensional cube, so you can see irregularities that a picture alone would hide. This tutorial inspects a look, repairs it and exports it.

Steps

  1. Load the look. Open Grade, then Lab, and load the look you want to inspect.
  2. Orbit the cube. Orbit the three-dimensional view to examine the colour mapping from different angles. Look for abrupt changes or irregular structure.
  3. Repair artifacts. Use Repair artifacts on the selected look. Compare the repaired version against the starting point and against the picture itself.
  4. Export a .cube file. Export the result as a .cube file when it is ready. Keep the original and the repaired version clearly named.
  5. Judge it on the image. Inspect the transform, then decide on the footage.

Notes

  • In the recording the repair strength is 55 percent. Both the original and the repaired exports contain 2,197 colour nodes; only the values differ.
