Body price is the variety of particular person video frames that your digital camera captures, per second. In video manufacturing, a video’s body price is expressed as frames per second (fps).
If in case you have a body price of 24fps, meaning the digital camera is capturing 24 particular person frames each second, and when performed again, it shows as one steady video.
The most effective body price for video is — any of them! That’s as a result of every body price has a selected use case.
Right here’s a breakdown of among the most typical body charges:
24fps: Cinematic Standard
For cinematic movie and tv (and a few on-line video) 24fps is the usual. That’s as a result of this body price feels probably the most cinematic, and appears probably the most pure to the human eye.
- It’s the usual for any function movie.
- It’s the usual for many TV.
- It’s probably the most cinematic body price out of all.
Why does 24fps really feel “cinematic”? Traditionally, 24fps grew to become the usual body price for motion pictures and tv as a result of it used the bottom quantity of movie whereas attaining pure movement to the human eye. Now, it’s extra of a creative option to emulate the look of “movie” and keep a disconnect from the hyper-realism you can obtain with greater body charges like 60fps and 120fps.
30fps: Video Standard
For dwell TV, sports activities, or cleaning soap operas, 30fps is frequent. 30fps has six extra frames per second than 24fps, giving it a smoother really feel that works properly for dwell TV.
- It’s normal for Reside TV and sports activities
- It’s normal for cleaning soap operas
- It’s normal for video recording apps on smartphones
What does “fps” stand for? It’s fairly easy! The acronym “fps” stands for “frames per second” and is how we measure body charges.
60fps: Slow Motion Standard
Some movies and digital movies are shot at 60fps, which when performed at regular pace creates hyper-real-looking footage. 120fps, 240fps, and better body charges are used for recording video to be performed again in gradual movement.
- 60fps is usually used to seize hyper-realistic footage or to file computer-generated graphics like video video games that match the refresh charges of our monitor screens
- 60fps, 120fps, and 240fps are all excessive body charges used for slo-mo.
- Usually, video is recorded at the next body price after which slowed right down to 24fps or 30fps in post-production to create that clean slow-motion impact.
- If you happen to tried to do the identical factor with a video shot in 24fps, it could appear like uneven gradual movement as a result of there aren’t any additional frames like there are in a body price like 120fps.
24fps vs. 30fps vs. 60fps vs. 120fps
The distinction between completely different body charges has to do with how the picture seems. 24fps, 30fps, and 60fps all have completely different seems, with the primary distinction between every being the variety of frames captured per second.
When selecting your body price, you’ll need to needless to say the upper the body price, the slower the gradual movement can be. For instance, movies recorded in 60fps or 120fps will then be slowed right down to a 24ps body price, which creates that clean slow-motion impact. If you happen to ever play again a 60fps or 120fps how it’s recorded, you then’ll undoubtedly discover a strange-looking impact.
Which fps are considered high speed?
Any body price at 60fps or above is taken into account a high-speed body price. For instance, 60fps, 120fps, and 240fps would all be thought-about excessive pace and are usually used for slow-motion video. Some cameras may even go as quick as 1,000 frames per second. You’ve most likely seen some examples of this body price in movies of a bullet in slo-mo, or a balloon popping.
Can the eye see more than 60fps?
Sure! The human eye can react to visible alerts in lower than one millisecond, or translate that to a body price of 1,000 fps. However, relating to the screens that we use to view video, most LCD screens solely have a refresh price of 60 hertz (hz). This implies, even when we had been viewing one thing at 1,000fps, it could basically solely ship 60fps to our eyes.
Does higher fps mean higher quality?
A better fps does not imply the next high quality video nor does it enhance the video resolution of your footage (e.g., 1080p / 4K). It does, nevertheless, seize extra frames, which lets you seize motion footage with ultra-realism and video that can look clean when performed again in slow-motion.
Relating to video body charges, “drop body” and “non-drop body” refers to 2 completely different strategies for specifying the speed at which frames are displayed.
Non-drop frame
Within the non-drop body technique, the body price is specified as a complete quantity, reminiscent of 30fps or 60fps. Which means every second of video is made up of precisely that many frames, and the frames are displayed at a constant price.
Drop-frame
Within the drop body technique, the body price is specified as a fraction, reminiscent of 29.97fps or 59.94fps. Which means the precise price at which frames are displayed is barely decrease than the required price, and a few frames are “dropped” to be able to keep a constant price. This technique is often used when the video can be broadcast over tv, the place the body price should be synchronized with the printed sign.
Typically, the drop body technique is used to take care of a constant body price in conditions the place the precise body price might fluctuate barely. This may be necessary for guaranteeing that the video seems clean and pure to viewers.
On most DSLR cameras, the body price could be present in one of many first couple of menu pages. When you find the menu web page, you’ll see two choices for every body price, IPB, and ALL-I. IPB means extra compression and smaller total file measurement, and ALL-I means much less compression and the next file measurement.
By default, your iPhone’s video recordings are set to 30fps. You possibly can regulate your iPhone frame rate within the File Video subsection of the digital camera settings menu.
- Go to the Settings app
- Scroll right down to Digicam
- Go to File Video
- Modify the body price of your iPhone movies

What’s the distinction between body price and shutter speed? In video recording, the body price is a recording format and accounts for the variety of particular person video frames your digital camera captures. The shutter pace impacts how shortly your shutter opens and closes, affecting the publicity of your shot; you should utilize shutter pace to brighten or darken your picture.
There you might have it: body charges, defined!
