In motion pictures, television, and in computer video displays, the frame rate is the number of frames or images that are projected or displayed per second. Frame rates are used in synchronizing pictures, film, television, video etc.
What is 24 frames ?
- In video technology, 24 frames refers to a video format that operates at 24 frames per second frame rate. Originally, 24p was used in the editing of a film. Today, 24p formats are being increasingly used in delivering film-like motion characteristics.
- The human eye is capable of differentiating between 10 and 12 still images per second before it starts just seeing it as motion.If a frame rate is too slow, motion looks jagged, but if it's too fast it seems to be realistic.
- We generally hear 24 fps is used in making a movie. In earlier days when you add sound to a movie with low fps the lip sync was missing and it didn’t feel real. Adding a sound at 16 fps and 18 fps film was also expensive.
- So they decided what is the lowest amount of frame rate we can get away with sound and 24fps was about possible the lowest number they could get away with. They even tried at 22 and they had some editing difficulties.
- When u increase the fps for a movie (More then 24 fps ) it actually looks like a play where costumes looks like costumes makeup looks likes makeup and fantasy decors looks like CGI.
- In short, higher frame rates look more real, but it makes things that are not real look less real. So at 24 fps motion blur which soften our movies.
Why we use more then 24 fps in video games ?
- A single frame from an action shot in a movie is somewhat blurred due to the movement. However, each frame of a video game is clear - no motion blurring.
- Therefore, it takes a higher frame rate for a game to look good than it does for a movie.
24 fps : Standard for movies
30 fps : It is mostly used in capturing images (phones, cameras etc)
60 fps : Smooth motion (mostly used in video games )
120/240 fps : Slow motion (It captures at 120/240 fps and plays at 30 fps)
Time lapse / Fast motion : It captures 1 min / 10 min per frame (it depends on requirement) and plays at 30 fps.
Ex : sunrise videos, traffic videos etc.
