Question Sprite animation interpolation solutions

Hello,


Characters in my game use sprite animations.
Each state (idle, attack, hit, etc) has 10-20 frames of animation.

At some point I got wondering - is it possibile to artificially increase number of frames so that the animations would look smoother?
Is it a good idea at all? What are the options?

Why I got interested.
Some time ago I got shown several videos in which frame rate was artificially increased to 60.
It looked silky smooth though felt slightly uncanny.
Anyway result was really impressive.
Now I got interested if it's possible to do something similar with sprite animations.
The style is semi-realistic. "Grime" is probably the closest example.


Kind regards,
nTu4Ka.

 

This might be interesting.
You can do a lot with the animator, although this might not properly answer your question.
