Frame interpolation is so incredibly awful looking in my opinion. Especially when it comes to animation. I can not comprehend all of the people on Youtube that take a beautiful drawn animation that is intentionally 24 frames per second and increase it to 60 thus ruining the hand crafted perfection of the drawn key frames.

Very little hand drawn animation is done a 24 fps. Which make interpolating the actual movements even crappier.

  I think the phrase they use is "drawing on 2s" for every second frame (12 fps) being drawn and "drawing on 3s" and so on depending on how many native frames there are between drawn ones. Usually, different things onscreen will be animated differently for effect/budget.

    Question: Does this mean that animators draw every 2nd or 3rd frame and then some technology interpolates the missing frames? It sounds to me like that is not fundamentally different from interpolating 24 fps to 60 fps. I suppose there are two differences: 1. The artist retains control of the interpolation between drawn frames. 2. The computational resources available to the artist far exceed those available in the TV. Apologies if this is an uninformed question, I watch animation but don't know how it is produced.

      The amount of keyframes in animation is not even close to 24 and everything inbetween are called "tweens" for obvious reasons. From my understanding the tweens are actually drawn as well, but can be delegated to non-lead artists thus don't require as much artistic decision making. You get the key frames and then draw what you believe would be the transition. I suspect with modern digital animation you could do a lot of the tweening automatically on the computer, but even then you would be carefully selecting them and fine tuning it to match your vision. Then at the end you would actually have 24 frames per second to turn into your final video. You shouldn't have any frames where something is mid-movement and blurred between the two positions.

        Thanks for clarifying that. Sounds like a training ground for the artists (until they are fully replaced by digital tweening.)

A lot of good animators will also vary how many frames they animate per second. Trying to smear all of it into 60fps doesn't improve anything. A good example is FUNKe[0], He's got a style with very pronounced changes in framerate. One movement will be 3fps and the next 30, never mind that the lipsync tends to be at a high framerate no matter what the rest of the animation is doing. Imagine trying to convert that to 60fps and still have it look good. [0] e.g. https://www.youtube.com/watch?v=maqIaT_ZUxs https://www.youtube.com/watch?v=maqIaT_ZUxs
