I tried to follow the tutorial on https://www.videostudiopro.com/en/pages ... e-objects/:
I made a copy of the video on the Layer 1 track, selected that, opened the mask editor and drew a line over the microphone cable, then feathered and reversed the mask.
However, the options to start creating a movement mask (Detect movement and adjust mask to end of clip) are greyed out and stay that way even if I press the Play button like someone suggested in another thread. I can not select them. Same applies to the keyframe buttons.
What is wrong with this clip? See the screenshot below (Dutch language version)
