What made you cut 2 frames from that arc. The animation does look better afterwards but how did you know that it would look good.Is it something that comes with years of practice or is it something that you just know?
Hey Abhi,
That comes from training your eye (experience). It doesn't take years but probably a few months of consistent training. But the more experience you gain, the quicker you will see and notice what the solutions are.
For example - when I was in my first year of animation school I would have figured out that subtracting 2 frames would make it better....but it probably would have taken me an hour or 2 or trying to figure out what was wrong.
It only takes a few seconds now.
Hope that makes sense.
