Wwas it this one -- 'Fujitsu fi-5530C scanner for animation drawings' ? I believe that was Toonboom Animate Pro (before it was renamed Harmony).

The normal work week at Disney was a 40 hour work week (8 hours a day , 5 days a week) . However, often near the end of production on a film we had what was called "crunch time" for a period of weeks or even months in some cases, where we would work overtime hours. On some of the films the amount of overtime was quite extreme, with artists sometimes working 12 - 14 hour days , 6 days a week, amounting to 60 - 80 hours a week . It varied by production. Some productions had many major story changes made during production which meant that sequences had to go back into animation to be redone and that was sometimes near the end of production (but the release date for the film did not change!) hence the "crunch time". Other times the work moved along in an orderly manner and just a normal work week of 40 hours was sufficient to get everything finished on time. --- Salaries varied. It's not easy to answer that question. There was a base pay rate for each job category set by the Animation Guild (union), but many artists worked at "above scale" (higher than the base pay rate) based on their experience and skill level.

Well, animators have always what we call "Layout" its the background in a simplest uncolored version and you animate on it. for the second question thats right you animate in that order, you animate the water reacting to the caracter's movement, and when you have a moving camera, you just have a bigger background. This is how it works in a simple way.

If I were to take a guess, It would be the Fleischer Bros. leaving the studio, Plus the ever-dwindling budgets of the 50's & 60's.
