Author’s Words:

There are many occasions you need to convert VFR to CFR for your video. But to make a perfect conversion, you'll need a reliable video frame rate converter. In the following article, I will introduce such a converter and show you how to convert video to constant frame rate with it. Read on.



Variable Frame Rate vs. Constant Frame Rate

Frame rate means the speed at which still images, called frames, are displayed per second. There are two types of frame rates. One is constant frame rate (CFR) where the frames per second remain the same throughout the video; the other is variable frame rate (VFR) that changes over time for a video.

Compared with CFR, VFR can deliver more efficient media outputs. A video with VFR is usually smaller in size while keeping a decent quality. Hence it is widely used in recordings by smartphones, webcams, gameplay recording software, etc.

However, VFR has a big flaw: many video editors and playback devices cannot work well with video with variable frame rates. You are most likely to encounter an issue where video and audio go out of sync when you edit VFR video in editing software like Premiere Pro.

Fortunately, this problem can be easily fixed by converting VFR to CFR. The next part gives you the best frame rate converter for solving this issue. Read on.

Step 1. Launch HandBrake. Then click File to import the VFR video or Folder to import more VFR files.

Step 2. On the right of the top menu bar, open Presets and select your preferred output profile.

Step 3. Go to Summary and choose one container format (MP4, MKV, or WebM) from the Format drop-down list.

Step 4. Next, switch to the Video tab and change the Framerate (FPS) from Peak Framerate to Constant Framerate. You can modify the frame rate as well.

Step 5. Finally, click the top green Start Encode button to start the frame rate conversion.
