Q.1. What Got You Into Motion Design?
One of my favorite motion design examples are the opening titles to the 2005 movie, Kiss Kiss Bang Bang (https://vimeo.com/12312117). Its a pulpy murder mystery set in Hollywood and the opening credits setup the mood of the movie really well. You get the sense that's its a bit dangerous (characters actually die) but its still riddled with moments of comedy and levity.
The design of the piece is fairly graphic and quite reminiscent of a graphic novel and well-matched to the audio.
The timing of the animation is largely audio-driven where scene cuts and transitions match the beats of the music. One good example are the transitions near the end of the clip where the pages of the novel get splattered with blood droplets and move in time with the music. Really cool.
All the elements of the piece fit really well together from concept to final execution. No surprise since the guy who made it is the same guy who made the Ironman 3 end titles and also the Sherlock Holmes and RocknRolla title sequences.
Q.2. Compare the Animations
The animated example on the left is definitely superior to the one on the right.
The mechanics are responding correctly on the right, where as on the left, the timing of the actions seem off and unrealistic if we're to believe the little magenta ball has any weight. Here are a few differences
1. Ball rolls around in the half-pipe looking arc and gets flipped out of it --
Left side -- ball rolls down the arc and slows near the top right edge correctly before rolling back the other way. When the ball rolls back, the arm of the arc flips it out at the right time so we believe the ball has weight and has been launched into the air
Right side -- ball rolls down the arc and kind of abruptly stops/reverses direction (no ease) and starts back the other way. The ball in this case gets launched into the air before it reaches the right spot in the arm of the arc...so it doesn't look believable that its responding from being catapulted by the arch.
2. The ball sails in the air and lands on the left side of the flip-gate (or teeter-totter/seesaw).
Left side -- ball eases in the air at top of its arc before falling on the gate, which flips down correctly in response to the weight of the ball.
Right side -- doesn't look like the ball eases during the arch of its travel in the air before landing on the flip gate. It also doesn't seem to rest on the flip-gate long enough (just a split second anyway) before falling unto the table.
3. Ball lands on platform, left-piston wind-ups and smacks it to the right end of the platform.
Left side -- the left piston winds-up believably...it pulls back quickly, slows towards the end of its wind-up and shoots out quickly and smacks the ball away to the right. Then it eases back (kind of a slow recoil) abit. The ball shoots right with a velocity matching the speed of the piston.
Right side -- the wind-up and firing of the left piston, is too linear in its motion. The speed is too constant so that when it makes contact with the ball and it flies to the right, it looks like the ball is launching itself rather than receiving a transferrance of the kinetic energy from the piston.
4. Lastly, ball falls on surface of right piston and gets launched vertically into the air and out of top of the scene. This portion of the animation probably has the least noticeable difference. The piston seems to ease back and bounce and spring forward correctly except:
Left side -- The weight of the ball seems to be depressing the last piston. Also the ball bounces off the right wall slightly as it falls down unto the piston's head.
Right side -- the ball doesn't seem to bounce back much...kinda sticks to the right wall a bit, before it moves down as the piston winds up.
That's all I noticed. All in all the left side animation felt much more believable.
