Top 7 Best Frame Rate Converters for PC and Mac

By Cecilia Hwung | Last Update:

Summary: No matter you want to increase FPS - 30/60FPS to 120/240FPS lower it down, or unify mixed frame rate, such as converting 23.97/24/25/29.97 to 30FPS, you will find the frame rate converters here useful for your specific situations.

The frame rate of a video decides how many frames will there be in a second. Frame rate above 12 FPS will be perceived by human eyes as motion, though low FPS will still look choppy. High FPS videos are much smoother and are ideal for creating slow-motion videos.

Besides, there are times when we need to conform mixed frame rates to a certain value. For instance, there may be DVDs ripped and saved at 29.97 FPS, 23.976 FPS, or movies at 24FPS, while modern-day cameras and mobile phones mostly shoot at 30 FPS. Using a frame rate converter to batch convert FPS can enhance productivity and keep everything tidy.

At other times, we simply want to change the video frame rate to perfectly suit social media. Such as using 30FPS or 60FPS for best YouTube upload settings, instead of sticking with those decimals.

VideoProc Converter AI - Change Frame Rate with Best Quality

VideoProc Converter AI offers both an AI tool and a traditional way to change video FPS.

The non-AI tool offers these Frame Rates: 15, 23.976, 24, 25, 29.97, 30, 50, 59.94, and 60FPS. The AI tool (Video Frame Interpolation) allows users to increase the FPS to 2x, 3x, 4x, and 5x of the source video. For instance, converting 30 FPS to 60/90/120/150FPS. You can surely repeat the process, and boost FPS up to 480FPS or higher.

The traditional tool in VideoProc Converter AI already delivers high-quality output, and the AI Frame Interpolation tool will bring the quality to the next level. It uses deep convoluted neural networks to generate realistic new frames in between, allowing you to create ultra-smooth slow-motion videos later.

Frame Rate Converter in HandBrake - It Only Converts from High FPS to Low FPS

HandBrake is listed on many blogs as one of the best frame rate converters. But many authors didn't mention that HandBrake only supports converting high FPS to low FPS.

This may sound contradictory, but you may see there are 100 and 120 FPS in the Frame Rate options. What happens if the source video is 30 FPS, and you choose 120 FPS? Isn't this option designed to increase the frame rate? Based on our test, no, it won't.

The frame rate options here in HandBrake only serve as a way to limit (decrease) the FPS of your source video. If your source video is 240FPS, and you choose 120FPS, then HandBrake will convert 240 to 120. If your source video is 60 FPS, and you select any FPS higher, the output video will stay at 60.

FPS Converter in HandBrake

In a word, if you need free open-source software to decrease FPS, HandBrake is a nice choice.

Step 1. Install the latest version of HandBrake, and launch it.

For some users, you may be prompted with the error saying .NET framework is missing. Just follow the instructions in the software to download and install the corresponding .NET for HandBrake.

Step 2. Drag and drop the video into HandBrake, or click the File button to import the video.

Step 3. Check the frame rate of the source video.

It is displayed next to the file name in the Source section.

Step 4. Go to the Video Tab, and click the drop-down menu of FPS to select the desired value.

It only works for the frame rate that's lower than the FPS of the source video you checked in step 3.

Step 5. Select an output directory, and click the green button "Start Encode".

Frame Rate Converter in VLC - Set Custom Frame Rate

VLC can be temporarily repurposed as the frame rate converter, if you don't have one at hand. It is free and lightweight to use, though the output quality can be compromised. VLC supports both increasing and decreasing the frame rate, though the maximum value you can enter is 99FPS. If you want to convert video to 100 FPS, 120 FPS, 240FPS, 480FPS and so on, resort to method 1 above.

Before you get started, check the frame rate of the source video in VLC: go to Tools > Codec Information. Under the codec tab, you shall see its frame rate.

Convert and Save Option in VLC

Step 1. Launch VLC and go to the Convert/Save option.

Step 2. Add the +Add icon to import the video and click the Convert/Save button at the bottom.

Step 3. In the convert window, click the spanner icon to open up the Profile Edition window.

MPEG Streamclip - Free Frame Rate Converter for Mac

MPEG Streamclip is one of the best free video converters for Mac. The frame rate converter inside this tool is easy to use.
