I have been doing a bit of rotobrushing some video and I have a couple of questions about this process.
I double click my layer and begin using the brush around my figure. If I skip forward frame by frame I noticed after 19 frames the video is no longer rotobrushed. Is this normal? I must redo the brush every 19 frames or so?
You ended up outside the propagation span which defaults to 20 frames. This will create a new base keyframe and requires to define the areas fresh. if you move inside the propagation spans, the automatic detection will work and you can extend that step by step....
Where is this propogation span and how do I stay inside it? How do I extend step by step? Ive searched for some good tuts on this but most are lacking details.
