Dick Huemer on Timing - Feb. 20th, 1936
Discussed are the then just-released Mickey's Polo Game (beginning with Huemer's own scene 32) and the 9-months old Water Babies [mentioning Huemer's own toreador and bullfight sequence], but examples are also found in Alpine Climbers which would not see daylight until five months later, as well as The Band Concert, On Ice and The Tortoise and the Hare, all released the previous year.
Among the people asking questions are Al Eugster and the feared but not very respected George "Flop-ears" Drake who headed the inbetween department.
Note especially the interesting snippets of information on animation to music, the use of "twos" and extremes vs. straight-ahead animation on pages 5 and 6. Later on we get Huemer's take on Speed Lines. This was a period of learning by doing, the pioneering spirit still permeated the studio, and you feel the openness to exchange ideas and the eagerness to get to the bottom of the craft.
That said, I feel I need to point out that the things discussed here still hold true today, also in computer animation. A principle is a principle, whatever the medium. If we do not learn about the successes and failures of yesterday, how can we be sure we make the right decisions today? Don't mistake these documents for "funny old stuff." If you are employed in the animation business, know that they are part of the groundwork of what pays your salary today!
