An MP4 file doesn't have a fixed frame rate; it can support various frame rates depending on the video encoding settings used when creating the file. The most common frame rates for video content, including MP4s, are 24fps, 25fps, 30fps, and 60fps.
Here's a breakdown:
-
What is Frame Rate? Frame rate refers to the number of frames (individual images) displayed per second in a video. It is measured in frames per second (fps). A higher frame rate generally results in smoother motion.
-
Common Frame Rates for MP4s:
- 24fps: Often used for movies and cinematic content, aiming for a film-like aesthetic. This speed accounts for motion blur, an optical effect that makes moving objects look out of focus due to quick movement (as noted by Adobe's article on frame rate).
- 25fps: A standard in PAL television broadcasting (Europe and other regions).
- 30fps: Common in NTSC television broadcasting (North America and Japan).
- 60fps: Increasingly popular for gaming videos and sports content, offering a very smooth and fluid viewing experience. Often used when slow-motion effects are desired.
-
Factors Influencing Frame Rate Choice:
- Intended Use: Consider where the video will be viewed (e.g., online streaming, television, cinema).
- Aesthetic Preference: The desired look and feel of the video.
- Technical Considerations: The capabilities of the recording equipment and editing software.
-
Checking the Frame Rate of an MP4: You can usually find the frame rate in the video's properties on your computer or within video editing software.
In summary, the frame rate of an MP4 video isn't fixed; it's a parameter set during the video encoding process, with 24fps, 25fps, 30fps, and 60fps being the most commonly used.
