Hello I am a super new beginner to After Effects and I seem to be having a rotobrush problem. It could be just me.
I have been trying to remove a character from a background to put them in a new one and so far I'm doing everything OK. I select the character with the rotobrush tool ect. but when I go to the next frame I cant add or subtract from the propagated frames which poses an issue seeing as how there are some small adjustments to be made in what the rotobrush has selected. I have looked at multiple tutorials and surfed some forums but I haven't found a solution. Is it just me or am I overlooking something?
The Roto Brush tools are not a good place for a beginner to start. This is a rather advanced part of the program.
