These frames are a before and after study in rotoscope, learning from Magno's Borgo CmiVFX training. Mocha's ability to provide good mattes for coloring and finishing to different 3rd party softwares is just the tip of the iceberg.
One may think "you could easily color correct it with power masks and hsl keyers", and in fact I could, but hey, what's the point in solving problems always in the same way? Doing what I already know will only put/lead me to the same skills level I already have/am.
The goal is to be always learning and improving.
