Rectangle Crop Screws Up LUT Colors

Bug
1

Any time I use a LUT (on track or individual clip, doesn’t make a difference) using a Crop: Rectangle of any sort distorts the colors that the LUT put in place. If I tweak the coloring so that the LUT looks correct again, removing the crop reverts it back to another (now wrong) color. I cannot figure out why a crop would screw up a LUT’s colors. I have tried both with black padding and transparent padding and it does not make a difference. Tried with multiple LUTs from different sources to no avail.

Try changing the order of the filters.

I did not reproduce it.

I have run them in varying orders, including making sure the crop loads absolutely last.

There might be something else going on that I did not get from your description. Try to reproduce the problem in a new project and write the steps clearly. For example, what I did for the screenshots above:

  1. Start Shotcut
  2. Double-click a video from Recent to open it
  3. Press A to add the video to the Timeline
  4. Select the timeline clip
  5. Add the LUT filter and choose my LUT
  6. Add the Crop: Rectangle filter and make the rectangle smaller than full size.
