What is the Frame Rate in the Video?

what is frame rate in video

A movie of 24 frames per second, for example, presents 24 independent still images every second. The motion of a video varies depending on the number of frames per second selected during shooting and playback, including regular speed, slow motion, time-lapse, and more.

Different Common Frame Rates for Video

The majority of silent films were shot at 16 to 18 frames per second and projected at 20 to 24 frames per second. Early filmmakers and animators developed techniques to produce a motion perception between 12 and 16 frames per second through trial and error. Anything below this threshold gave the brain the impression of a sequence of separate pictures. This motion is what makes comedies like Charlie Chaplin's so funny.

With the introduction of sound in films, filmmakers felt the necessity for a consistent frame rate, and 24 frames per second became the preferred option.

24fps

The typical minimum frame rate for capturing video with convincing motion is 24 frames per second. This is the typical cinematic video frame rate for movies and television shows. It looks the most cinematic and is the most like how we experience the world. Motion blur is standard in complicated situations taken at 24 frames per second.

30fps

Even though 24 frames per second are the conventional movie frame rate, 30 frames per second have been the standard for television for many years. Thirty frames per second provide a somewhat smoother visual presentation and detailing at a fast speed. However, the video will appear artificial in slow motion and may have a soap opera feel.

60fps

Anything with a frame rate of 60 frames per second or higher frame rate video offers a very smooth and clean image. When there is a lot of movement or motion on the screen, we employ higher frame rates. Many video games and action movies use 60 frames per second to show slow motion with great detail and smoothness. Greater frames show more detail. Sports are usually filmed at a higher frame rate to show replays clearly.

120fps

Photographs taken at 120 or even 240 frames per second of a fantastic football kick, game automobile spinning, or a baseball batter swinging his bat are incredibly smooth and crisp. Gaming with 120 fps or above is considered realistic and fast-paced. The game will run quicker if the hardware system has more processing power. Ang Lee also filmed Gemini Man at 120 fps.

Relationship Between Frame Rate Video and Resolution

When capturing video with a Smartphone, you have numerous options to change video frame rate and resolution. The greater the resolution, the more pixels there are. For example, 720p HD at 30 frames per second, 1080p at 30 frames per second, 1080p at 60 frames per second, or 4K at 30 frames per second. Let's look at how video resolution influences frame rate and vice versa.

The pixels of a 16 MP resolution is 4928 x 3264. Thirty frames per second, 16 million pixels each frame, takes 1/30 of a second to generate. The rendering time cannot be longer than the frame rate. Remember that the GPU is in charge of the frame rate while the CPU controls the resolution. The resolution suffers when the GPU has to work harder to produce a picture. Anything exceeding 30 frames per second attracts the attention of gamers and graphic aficionados. The difference between 720p and 1080p resolutions may go unnoticed by the typical observer. However, the difference is discernible with higher resolutions such as 4K and 8K.

Does Frame Rate Affect File Size?

If you increase the frame rate of the video, the animation becomes smoother. More photos per second of video equal more information and larger files, which takes longer to export. While high-quality video is always desirable, greater frames per second (fps) mean larger files and more bandwidth use. Reduce the bit rates or frame rates to reduce file size. Loss of bit rate while maintaining frame rate reduces visual quality. Combining a high resolution, a fast frame rate, and an appropriate bitrate value affects the video quality.

Best Cinematic & Standard Video Frame Rate for 4K 

Previously, videos with a native frame rate of 24 FPS had to go through a pull-down procedure when viewed on devices that supported 60Hz. This converts the video's 24 fps to the device's 60 fps. 

The newer standard frame rate for video offers 30, 60, 120, 240, or 300 frames per second due to similar unequal frame doubling. These specifications are appropriate for both theatrical films and 4K monitors. It's important to remember that 4K refers to device resolution and has nothing to do with video frame rates.

Best FPS or Video Frame Rate for YouTube Videos

YouTube supports 24 to 60 frames per second and up to 8K resolution. For YouTube videos, given below are some of the most popular video frame rates.

  • Talk shows and video podcasts - 30 frames per second
  • 60 FPS Gaming Highlights, Montages, and Makeup Tutorials
  • Academic and learning films, as well as Fitness and Health Channels — 24-30 frames per second
  • Sports Highlights – 40-60 frames per second

Slow-motion and Time-Lapse Video Frame Rate

Slow-motion occurs when the shooting video frame rate is higher than the playback frame rate. As a result, the higher your video frame rate during shooting, the slower things look on playback.

When we film a movie at  120 frames per second  and play it back at 30 frames per second, it seems four times slower. 

  • 60 FPS  – Things appear to be moving slowly (blowing candles on a cake, people walking)
  • 120 FPS  – Things appear to be moving a little quicker (pets running, slower sports)
  • 240 – 480 FPS  – Motions that are too rapid for the eyes to see (fast sports, water splashing, skiing, golf swings)
  • 960 FPS  – Great for popping balloons, destroying items, and explosions.

Time-Lapse Video Frame Rate

A succession of still images is captured and played at a higher frame rate in time-lapse filmmaking. This gives the appearance of fast movement, as though the subject is moving extremely quickly. The movement of stars at night, dawn and sunset, and plant development are time-lapse photography examples. The suggested standard shutter speed for time-lapse photography is double the frame rate. A photograph was taken at 25 frames per second; for example, it should have a shutter speed of 1/50.

Use this easy math to determine how many shots you'll need for your time-lapse: Total frames required = (desired frame rate)*(clip length in seconds). For instance, if the film is 30 seconds in length and filmed at a frame rate of 30 frames per second, 900 photographs are necessary.

Best Video Frame Rate for Gaming

In general, games might be of the 'thinking kind,' with slow-paced gameplay, or the 'twitch reaction,' with fast-paced gaming. A game's frame rate is typically 30 frames per second. Despite this, most gamers consider 60 frames per second to be the best frame rate for video gaming due to its quick response, smoothness, clarity, and viewing experience.

A low frame rate may be acceptable in slow-paced games like Civilization, where graphic changes occur infrequently. On the other hand, games like Counter-Strike demand a high frame rate since the player must turn in many directions within seconds. As a result , although playing Civilization at 30 frames per second is fine, playing Counter-Strike at a low frame rate is exasperating.

Triple-digit frame rates such as 120 frames per second (fps), 144 frames per second (fps), and 240 frames per second (fps) are for very competitive players. Still, many people love playing single-player games with exceptional responsiveness , low input latency, and no tearing. Sony has previously said that their next-generation systems would be capable of 120 frames per second. At 120 frames per second, titles like Ghost Runner, Call of Duty: Black Ops Cold War, and Borderlands 3 are accessible.

  • 30 FPS  – Minimum frame rate at which the game may be played. Anything below this causes a lot of shuttering. 
  • 60 FPS  – Frame rate is ideal. PS5 and Xbox Series, as well as most gaming PCs, use this.
  • 120 FPS  – Ultra-smooth, Extra adaptability. High-end gaming PCs use it.
  • 240 FPS  – This setting is just for the fastest 240 Hz displays. Sports games provide the best experience.

Instagram, Pinterest, and Twitter Video Frame Rates

  • Facebook  feed video, video advertisements, and IGTV - minimum 30 frames per second
  • Pinterest video advertising with a minimum frame rate of 25 frames per second
  • 30-60 fps Twitter Ads & Native Videos

After you've finished editing, it's time to export the video. It's now time to adjust the Frame Rate. YouTube supports up to 60 frames per second; thus, that choice will be available in the dropdown menu. Now you may save your work by pressing the Save button.

It's critical to note that putting the highest frame rate video higher than the actual rate will not magically raise the FPS. On the other hand, you may set it to lower, and it will reduce the frames following your selection.

Additionally, you can adjust the video resolution. If you set it higher than the actual video resolution, you can get a pixel stretch, resulting in a loss of video quality.

Conclusion

Frame rates are used differently depending on what you're recording or what program you're using. For video, 24 frames per second are optimal for a cinematic aesthetic. Higher frame rates are required to capture more motion for better slow motion and smoother footage . Higher frame rates at larger resolutions provide the best performance in games but at a higher expense. High frame rates on traditional gaming consoles result in decreased resolution; however, this is not evident in HD. When playing games at 4K or greater resolutions at high frame rate video, the resolution becomes obvious; hence a higher refresh rate is recommended.
