I’ve been playing around with using Shotcut to do personal videos for socials and so on, coming from a background of professional editing and colour grading. One thing that I’ve found is that the colour wheels in the “Colour Grading” filter are waaayy too sensitive - moving them a pixel or two in any direction immediately sends you off into 2000s music video territory! Really they need about 10% of the sensitivity that they currently have to be useable for general colour correction duties.
I think an easy win would be to make the response non-linear from the centre of the wheel outward - perhaps something an exponential or ^2 response curve. That way you get nice fine control in the centre, while still being able to push it into “effect” territory toward the edges.
As always, thanks for all your work on FOSS!
