All kinds of animation use 25 fps and filmed movies.
Kasperg if your TV or computer show movies with slight lag thats because it shows less then 24 fps or it justs stops alot of times.
You can perfectly see a video with higher framerates if your input device
No you can't, you can't watch video with higher framerates then 24/25. Thats because phsically impossible, there aren't any more frames on the film or in the camera's memory to fill the gaps that will be created.
If you want to ask my brother, he studies animation, and already made a few short films, he makes only 25 fps for his films, and so all other animators, 3D, classic and stop motion. How will the TV/computer add more frames? Add blank frames? Copy a few frames?
And besides many cartoons use each frame twice, one after another, so basicly cartoons only have 12.5 fps.
And they still look smooth.
Conclusion, it's impossible to have in a TV more frames, basicly because they don't exist, the computer can create more frames because it creates them on the spot.
