I just saw something! I think TVPaint can use something like but more than just Nvidia cards. But if it can usefor all video cards. My dream slowly coming true to have anime 60 FPS! I've said 60 FPS anime in TVPaint forum a long time ago too. You can actually fit the budget, talking to SlowTiger. I want to disney render of FPS.
Something like the Dain AApp that can convert and 24 FPS Video in 60 FPS or a partifular FPS.





Here the site of the software. I think this is priority for TVPaint implement something like that.

Definitely not.

60fps is for gamers only, not for watching cartoons. Anybody who wants it uses special hardware anyway. It makes no sense to blow up file size and loading times in production of animation - "ain't nobody got time for this!" Do you really want to inbetween for 60 fps?

While I not agree with every aspect in this video he got some interesting points against converting animation from 24 to 60 fps

Yes, I'm not a fan of this "rant" style of presentation , but he does demonstrate the problem of "converting" (interpolating) animation at 24 fps to 60 fps. To my way of thinking , if someone really thinks it's important to have animation at 48 fps or 60 fps , then just do it honestly and intentionally by animating at the higher frame rate with the understanding that it takes a lot more work (why anyone would want to do 2x or 2.5x the number of drawings is beyond me , but whatever turns you on ... )


-------

I remember several years ago reading about Glen Keane animating his Google Spotlight Stories piece , "Duet", at 60fps and thinking "Well, ok, if Google is paying him for the extra time it takes to generate those extra drawings , fine. Why not ?" Now, I've never seen "Duet" in the VR format at 60 fps , only the conventional short film version presented at regular 24 fps . I'll admit I'm still mildly curious to see it at 60 fps, but I don't notice that the animation is lacking anything when viewed at conventional 24 fps.

On Google Spotlight Stories YouTube channel , the short film version of "Duet" plays at 1080p resolution at 24 fps . https://www.youtube.com/watch?v=x0Y35XLBY8A

Stepping through it frame by frame it appears to be a combination of animation "ON 1's" and "ON 2's" , in conventional terms. So I don't really understand if the VR presentation had interpolated frames to make it run at 60 fps or if the conventional short film presentation of "Duet" has had some frames removed so it runs at regular 24 fps ? However, if they had a 60 fps version I would have expected an option on YouTube to view the film at 1080p, 60 fps , but that doesn't appear to be the case.

Does anyone really feel like this animation lacks "smoothness" at 24 fps ?



But the main point being , if the animator intentionally animates at 60 fps , adapting his timing and spacing to that frame rate , it's ok , as long as the animator is comfortable doing 2.5x the number of usual drawings. What I find objectionable is the idea that someone who had nothing to do with creating the animation comes along later and decides to alter the animation that was originally animated at 24 fps (and looked fine at 24 fps) interpolating it by a computer program to 60 fps.

Interesting, too , that having experienced animating a project at 60 fps , Glen Keane's subsequent short films "Nephtali" and "Dear Basketball" are animated at conventional 24 fps. Apparently 60 fps was not that much of an improvement to persuade him to continue working at that higher frame rate ... or was it just the lack of Google's deep pockets to finance animating at 60 fps ? (I think it's probably the former , not the latter reason)

There's also the well-known phenomenon of converted animation being too soft, missing dynamic. This was observed in many a DVD of old shorts, you can easily spot them by taking screenshots which show a blurry blend of 2 or even more frames. It destroys all the animator's intentions. My decision about inbetweening, to draw 1 or 2 or more or no inbetween, is a conscious decision, I don't want any software mingle in and spoil what I've created.
