Here is a reel of roto-focused shots I have done.
I would take a variety of different stock videos and challenge myself to adapt and think about how to roto effectively to different shots.
I also used a mix of tools that I FOUND TO TEST AND CREATE A MORE EFFECTIVE WAY TO ROTOSCOPE. iNCLUDING cATTERY IN nUKE AND SECTIONING AND USING LESS KEY FRAMES TO DECREASE THE TIME TO RENDER AND TWEEN BETWEEN FRAMES.
