You are right, there are 10 colors. I rechecked it in aseprite. Thanks for pointing that out. 

BTW, by saying 5 hours I didn't mean it took me long:) I meant it was very quick - 5 minutes per 1 Arnold is quite fast;)

PS. I'm not sure why it is not parenting my replies to your posts.

Hi,

Thanks for your comment! To clear some things up - this work is actually quite far from automatic;) I did it to test new software (and it actually is my 3rd rotoscopy). The way I did it was to get the footage from YouTube into VPlayer. Then I randomly selected frames at 1-5 frame intervals (without the possibility of going back). Then I painted on base color and shadow.

Pixels and some shapes, as you rightly pointed out, are sometimes erratic due to the fact that this was not a very precise work (4 hours per 45 frames) and the fact that I only went forward with frames. So every time the footage went too far I had to improvise the shapes rather quickly. 

When all frames were ready, the irregular framerate I described above required me to set different frame durations for each frame in Aseprite to avoid unnatural motion (without it the animation would speed up and slow down randomly). The background (not rotoscoped) and tuning took me another hour so the final work was 5 hours.

Best regards

Paul
