I made 60fps Flipbooks using A.I.

The AI interpolation was definitely never made for animation, at least not yet. The purpose of AI interpolation was for real life movements from humans, animals and so on. For that purpose, it amazingly works well. Let's hope that in the future AI can properly smooth out the animations without making it look weird.

The green goopy monster was pretty good too I think, it just overall matched the characteristics of the green goop so like the fluid motion of the AI made it seem natural.

The first thing we learned at the Hollywood animator's union is that with inbetweens, it's not line to line, it's drawing to drawing, meaning every frame has to be a solid drawing. Inbetweening is actually hard. It's the guts of an animated scene. Walt Disney himself admitted he wouldn't be able to hold a job as an inbetweener in his own studio.

I agree, the balloon is the best, because balloons are floaty and squishy by nature. You were spot on when you said it messes up the timing of the movement, too, it makes some things start WAY earlier and makes everything very wobbly looking

I liked watching them like a stereoscopic image, "cross eyed" style. The merge of the two at the same time was trippy.

The only thing I've ever liked about the 60fps is dust or watery effects since it makes those particular random effects more realistic seeming without looking to weird or overly wobbley. I bet this tech could be used for some really cool effects to add onto an animation that's 12 or 24 fps with more duplicate frames to keep the snappiness.

The problem with animations being interpolated is how often it ruins very intentional timing and movement. There's often a "buildup and release" that ai smooths out too much and motions feel less weighty. Noodle has a great video going into more detail. This was an interesting experiment Andy! I agree with you, the original is so much more alive and snappy

One of the more jarring aspects of the smoothing is how it doesn’t know what to do with the differences in the textures between frames. That’s especially noticeable on the graveyard scene where the whole page is shaded and there is subtle changes in that evenness. I also thought the cloud really benefited from the extra smoothness. Clouds are amorphous anyway and wobbling makes sense there, and the smoothing really helps like it flows like a cloud.

Definitely looks a lot weirder when slowed down, but it's pretty impressive how much it blends in with full speed. I think it depends on a per-animation basis as to whether it looks better or not. Shouldn't be used for everything, but I absolutely get the appeal, especially for live action

7:11 It's also interesting the "logic" behind the added frames. For instance, it makes somewhat sense for the umbrella to make some motion in preparation for its opening.

idk, I liked both 12fps and 60fps. they both showed qualities that presented their own characters. i like how the ai tried to create tweens for the textures. it adds a new flow of movement to the peice, making things feel more organic. i find that it could be a useful but controlled tool in the animation industry. im not saying it will replace animators, im saying that features like this could be directly added to softwares like toon boom or even tvPaint to give animators the option to work on difficult animation projects as big as 60 fps. I assume the ai simply identifies the difference between frames presented. Then it creates an "in between frame" that displays an assumed position of the animated object. obviously its not perfect rn but its similar to how humans animate. Actually this is not much different to creating tween movents in TvPaint. you define the start position and frame of an object... then you define the end position and frame of the same object. then you hit create tween and like that, it has created in bewteen frames that mark the position of an object during a movement. you could have got a nicer animation if you increased the ai generated fps in intervals instead of generating str8 to 60. (eg. 12 -24, -24-36, 36-48, 48-60). going straight to 60fps probably made the ai reference frames it hasnt created yet, as it has to invent 4 frames between given frames, leaving you with out of place frames. Expanding the frame rate gradually however, lets the ai generate 1 in between frame based off clearer frames. this allows the ai to refence the difference between existing material, instead of it referencing material it has yet to create. the 12 fps mainly has that crisp feeling because its easier for us to identify the difference between each frame due to the frames being presented for longer. also theirs no in between motions for the textures and blemishes, therefore creating a rugged visual.

i think while the 60 fps version is interesting to look at, i find the originals to have far more emotion to them

Noodle has an awesome video about this that explains specifically why some animation isn't meant to be interpolated, and why we still generally prefer the original in cases like this.

1:49 the best rickroll ever😂😂 Edit: tysm for the 50 lik

That rick Roll was personal 1:45

I am a bit of stereoscopic 3D (cross eye) fan, and I noticed that when optically overlapping the side by side images, the AI generated side would provide alternate versions of the original flip book, rendering a 3D version of your animation! Very cool.😊

I feel parts are improved and others aren't. I think that the fps increasing ai should only be used on things 30fps or higher. Great video, Andy.

I think in general it definitely made things feel a little too smooth, like there was no real weight to a lot of it. The hits bounced more in the AI one which made everything seem kind of rubbery. I will admit though, the smoke at the end of the kamehameha from the girl felt very smooth in the AI one.

there is a significant amount of difference the title looks more cartoony and the fps seems more glued together, only when you slowed it down it looked weird

I Crossed my eyes to watch the side by side in "3D"...it was glorious
