What Is Frame Rate and How to Choose the Best Frame Rate [MiniTool Wiki]
What Is Frame Rate?
What is frame rate? It is the number of single video frames captured by the camera per second. There are several different standards for frame rates (expressed as frames per second or FPS): 24FPS, 25FPS, 30FPS, 60FPS, and 120FPS. To learn more information about the videoes, you can go to the MiniTool website.
Frame rate comes from the movie and the original silent movie. The film will be placed on a reel and then manually shaken by the camera operator, and the projector will then playback the film at the same frame rate as when recording.
You can regard the frame rate as a flip book: every new drawing on a piece of paper is a frame. When you flip through it, you will see that all the frames merge into a continuous moving image. So if you capture and play a video at 24FPS, every second of the video will show 24 different still images.
Why Is Frame Rate Important?
Frame rate greatly affects the style and viewing experience of the video. Different frame rates produce different viewing experiences. For example, movies are usually displayed at 24FPS because the frame rate is similar to the way we see the world and has a very cinematic look.
Live broadcast videos or more sports videos (such as sports events or video game recordings) often have higher frame rates. On the other hand, people who create animated GIFs usually sacrifice details to reduce file size and choose lower frame rates.
How to choose the Best Frame Rate for Video?
Then you may wonder how to choose the best frame rate for video. You should choose it based on your actual demands.
The difference between different frame rates is related to the appearance of the image. 24FPS, 30FPS, and 60FPS all have different looks. The main difference between each is the number of frames captured per second. The details of some of the most common frame rates are as follows:
For video recorded on the network, the maximum frame rate you may see is 24FPS. It’s the standard for any feature film and most TV. Besides, it’s the most cinematic frame rate out of all.
It is a close-second standard for video around the web. It’s the standard for Live TV and sports, soap operas, and many video recording apps for smartphones, like Instagram, use 30FPS. This post - The Best Instagram Video Format and Specification in 2020 maybe is what you need.
60FPS, 120FPS, and 240FPS are used to record video that will be edited in slow motion. Typically, videos are recorded at 60FPS and then slowed to 24FPS or 30FPS in post-production to create smooth slow-motion effects.
If you try to do the same for a video shot at 24FPS, it looks like intermittent slow motion since there aren’t any extra frames like there are in a frame rate as 60FPS. Besides, when you choose the frame rate, you should consider the motion, delivery as well as file size & export times.
Motion - When choosing a frame rate, the amount of motion needs to be considered in the video. If there is a lot of motion in the video, you may need to capture it at a higher frame rate.
Delivery – How video is transmitted (such as YouTube or broadcast television) and the devices people use to watch the video can greatly influence your choice of frame rate. Not all devices and transfer methods support all frame rates, so it's best to read them carefully before you start shooting.

File size & export times - The last thing to consider when choosing a frame rate is file size and export time. The higher the frame rate, the more packed still images in the video per second. More images mean more information and more information means larger files and longer export times.
