Hello, I have been trying to use the Opacity-->Mask-->Free Draw Bezier tool for the past hour and nothing has been working, I have uploaded a video to show you what is not working. Basically, i click but no mask is created, someone please help, thank you very much!
(forgive my writing, English is not my first language)
I watched your video, tried the same thing you did (3 masks, plus adding a new mask with the pen tool) and it worked. I'm using CC2017. Anytime Premiere doesn't behave like you think it should, restart your computer and restart Premiere.
