Which Is the Best Frame Rate (FPS) for HD Videos?
What Is Frame Rate?
Frame rate, also called Frames per Second or FPS, refers to the number of displayed images per second. The human eye captures images at a frequency of 24fps. As a result, images over 24fps, such as an image at 50fps or 60fps, appear to be sharper as well as smoother to the human eye.
There are several common frame rates for video recording, namely values from 24 to 120fps (including 24, 30, 50, 60 and 120fps). As long as the value is in that reasonable range, the higher the frame rate, the smoother human's perception for final image.
The Most Common Frame Rates
In most of the cases, there are three different frame rates supported by movie cameras and DSLR (Digital Single Lens Reflex Camera), namely, the standard 24fps for movies, 30fps for videos with TV style, and 60fps for scenes related to sports and fast motion. Other frame rates supported by devices are different from one to another. Take the latest OSMO of DJI for example:
• For 4K Ultra HD 3840 x 2160 (2160p): 24/25/30/48/50/60fps
• For FHD 1920 x 1080 (1080p): 24/25/30/48/50/60/120fps
Indeed, 23.98, 24fps, 25fps, 29.97fps, 30fps, 50fps, 59.94fps, 60fps are all commonly used for HD or FHD videos. Confused by variant fps? Wonder which one should we choose for HD videos? Please read on for specific recommendations.
How to Choose the Optimal Frame Rate for HD Videos?
Actually, there exists no fixed choice when setting frame rate for HD or 4K videos. You have to adjust different fps number in response to diverse scenes or subjects.
• The Standard 24 FPS - Large majority of your recorded footage is captured at 24 fps. Even though the image might not be as smooth as that of a higher frame rate, such as 60fps, it can meet most of your demands by its cinematic performance.
• 24-30 for Time-Lapse Photography - The frame rate of time-lapse photography can be varied in a range around normal frame rate (between 24 and 30 frames per second).
• 60 FPS for 4K Video - Until 4K video resolution presented itself to the world, 60 fps were seldom used in photographing or filming. Nowadays, 4K videos with 60 fps display an extraordinarily vivid and detailed look.
• 120 FPS for slow-motion video - 120 fps is oftentimes applied to produce a slow-motion video. Gamers often use 120fps in their game play recording that include a plenty of fast movement.
However, High Frame Rate Video Are Not Friendly to Many Video Editors
A high frame rate video can help provide more realistic and detailed image in sports scenes or game play recording, but there is a haunting problem when it comes to the post-production of a high frame rate video - Many video editor apps are not compatible with a high frame rate video, especially 4k slow motion or time-lapse videos. In this case, we have to resort to one of the few programs that supports high frame rate videos, among which is VideoProc developed by Digiarty.
Convert and Custom Frame Rate for HD Video in VideoProc
VideoProc, a video processing and editing tool compatible with both Windows and macOS, is one of the optimal options for entry-lever users to deal with high frame rate videos. In this part, we'll share a beginner-level guide on how to process high frame rate video in VideoProc.
Step 1: Free download VideoProc
Go to the homepage of VideoProc or download the software here.
Step 2: Import the Original Video
Open VideoProc > click the first button "Video" to enter into Video Processing panel.
Click on the "+Video" button to add the original video from the local drive.
Step 3: Set the Frame Rate
After importing the video, click Option button to enter into format setting window.
Under Video Codec Options, you can change frame rate directly. You can turn a high frame rate video (120 fps for example) into a slow motion video by turning down the frame rate(to 60 or 30) > Click Done at the bottom.
For HD and 4K videos, 60fps is suggested if possible, since the higher the frame rate is, the smoother the video will look.
Tips: You can also change video quality, aspect ratio, and bit rate, etc. in this page. Back to the operating page, you can cut, merge, crop and convert your video
Step 4: Browse to choose the output path > click RUN to start the procession.
All in all, you have to choose an appropriate frame rate according to your shooting scenes/subjects (sports or game play recording, etc.) and your target video type (normal, time-lapse or slow motion, etc.) Besides, the post-production processing is usually indispensable.
