I remember analyzing an anime film doing a frame by frame snapshot of a 24fps anime and it’s timed using all 1s, 2s, 3s, and 4s in one scene. It was overwhelming to analyze. Heck I'd say they just placed drawings to see if it looks right without thinking whether to use 1s, 2s, 3s, and 4s.
Then again where JKR argument of animation that is strictly working with 4s is going to get unpleasant choppy results is understandable and a lot of people do criticized the look of an animation that is working strictly in 4s. Personally I wouldn’t work strictly on 4s myself.
By observation on specific well done scenes, it uses mostly 1s, 2s, and uses of 3s, 4s is used minimal. I find these break away of making the scenes looking systematical. Point is they use ALL frame types.
Another thought just came up to me is how to judge an animation. It’s the idea of judging the overall film as a whole or just one specific scene.
I know that in Studio Ghibli calls for a specific animator to do keyscene to bring out a specific emotion. There can be another scene where the studio called another specific animator to bring a different emotion. With great direction, the film can be amazing while working with a lot of different type of animators. This bring variety to the film.
Would it hurt if it is done in one specific way?
What happens if the studio uses an animator that provides a great visual scene but just simply doesnt work for the direction of the film but that same scene worked great in another film where it is directed differently.
Should we blame the direction? the animator?
Because of this, it is hard for me on how to judge an animation as it can vary.
Again this is just my opinion I admit I may have a bias toward anime so it may retract some people.
This is a place to share ideas and if someone has an opinion, I cant deny him/her to having an opinion. Its great to gather information.
So if I rate on what frame types to use in ONE scene, it would be:
Using all 1s-4s= awesome
Using just 1s=awesome
Using just 2s=awesome
Using just 3s=okay
Using just 4s=meh
