Variable Frame Rate vs Constant Frame Rate
Frame rate shows how quickly a number of frames (images) appear within a second. There’re two types of frame rates, variable frame rate (VFR) and constant frame rate (CFR).
Variable frame rate means the frame rate of the video is flexible and it changes over time, while constant frame rate indicates that the frame rate remains constant throughout the video.
In terms of video recording, VFR is an effective way to produce small file size. However, many video editing applications like Adobe Premiere Pro or DaVinci Resolve can’t deal with video that has a variable frame rate. To avoid this problem, you need to convert VFR to CFR.
Convert Variable Frame Rate to Constant Frame Rate
If you want to change variable frame rate to constant, you can use HandBrake, a free and open-source video transcoder that can convert videos from nearly all formats to MP4, MKV, and WebM.
As a popular video converter, HandBrake not only offers a rich variety of presets but also allows you to change video frame rate, video codec, dimensions, and more. Also, this program lets you convert variable frame rate to constant frame rate.
