Description Jonathan 2021-09-20 07:33:18 UTC

SUMMARY
I have several clips where I want to apply an RGB effect.
I group them and then add an Effect to the group.
Apparently effect is copied to all clips, but I dont see a way to control the parameters of all group clips effects in a single instance. I need to change one by one manually.

STEPS TO REPRODUCE
1. have several clips
2. group them
3. add RGB effect to the group
4. change the parameters

OBSERVED RESULT
only clip where the effect was assigned has the customised values

EXPECTED RESULT
all clips in that group have the effect with the values customised
