Color Grading filter: "Add a keyframe" button doesn't work

Bug
1

What is your operating system? Windows 10

What is your Shotcut version? 24.06.26

Steps

  • Add a Color Grading filter to a clip.
  • Enable Keyframes.
  • Move the playhead forward.
  • Click the Add a keyframe at play head button:
    • Doesn’t work. Keyframe is not added.
  • Manually change the parameter:
    • Keyframe is added.

I also noticed this:

  • Add a Color Grading filter to a clip.
  • Move the playhead forward.
  • Enable Keyframes.

Shotcut adds 2 keyframes. One at the first frame of the clip and one at the position of the Playhead. In other filters (SP&R in my example), only one keyframe is added at the position of the Playhead.

This is fixed for the next version. Basically, it did not work for any non-color and non-rectangle parameter that does not have a curve.
