Increase or decrease video speed without distorting the footage

The frame rate of a video is how many frames-per-second (FPS) a video has. The more FPS, the smoother the motion in the video. A video with a lower frame rate, especially below 20 FPS, will look choppy. You can adjust the frame rate in either direction to get the desired effect and file size you need. This article will teach you how to change the frame rate of a video using free software on your PC or Mac.

Changing a Video Frame Rate

You can use free video encoder programs like Handbrake or VLC to lower the video frame rate of a video. Increasing the video frame rate will generally not produce better quality video. However, programs like Flowframes and SVP Pro have the ability to interpolate video using AI and increase the frame rate.

Method 1
Method 1 of 4:

Using Handbrake

  1. Handbrake is a free video encoder that has the ability to edit the frame rate of your video. Use the following steps to download and install Handbrake:
    • Go to handbrake.fr/downloads.php in a web browser,
    • Click Download below your computer operating system (i.e., Windows, Mac, Linux), as well as your proper CPU (i.e., Intel/AMD, or ARM64).
    • Open the installer in your web browser or Downloads folder.
    • Follow the installation instructions.
  2. When you first open Handbrake, it asks you to drag and drop a video file into the box on the right. Use File Explorer or Finder to navigate to the location of the video file you want to change the frame rate for. Drag and drop it into the box.
    • Alternatively, you can click File on the panel on the left. Then navigate to the video file you want to open and click it to select it. Click Open.

  3. The tabs are below the drop-down menus at the top of Handbrake. Click the Video tab for options to change the video output.
  4. A good average frame rate is between 24 and 30 frames per second. Anything lower than 20 frames per second will result in choppy video motion.[1]
    • Increasing the frame rate beyond the original frame rate will not make the motion look any smoother. This will only result in duplicate frames and a larger file size. Handbrake can't add more frames to a video than what the original has. However, Flowframes for Windows and SVP Pro have the ability to interpolate video and add frames to increase the frame rate.
  5. Use the text box next to "Save as" to edit the file name of the video. This will allow you to keep a copy of the original video when you encode the new video.
    • To change the location the video saves to, click Browse to the right of this bar.
  6. 6
    Preview the video (optional). If you want to preview a small sample of the video before encoding it. Use the following steps to do so:
    • Click Preview at the top of the page.
    • Click Encode Preview.
    • Click Play.
    • Click Close.
  7. It has an icon that resembles a green "play" button. This starts encoding the video at the frame rate you selected.

Method 2 of 4:

Using VLC

  1. VLC is a free media player that has a built-in video converter, which can be used to change the frame rate of a video. Use the following steps to download and install VLC:
    • Go to www.videolan.org/vlc/index.html in a web browser.
    • Click Download VLC.
    • Double-click the installer file in your web browser or Downloads folder.
    • Follow the instructions in the installer to complete the installation.
  2. It's in the menu bar at the top of VLC.
  3. It's in the media menu. This opens the VLC converter.
  4. It's the button to the right of the box below "File Selection".
  5. Use File Explorer or Finder to navigate to a video file you want to change the frame rate for. Click it to select it and click Open. This adds the video to the file selection.
  6. It's the button at the bottom of the "Open Media" file.
  7. It's next to the drop-down menu across from "Profile". This opens the Profile Edition menu.
  8. It's the second tab at the top of the "Video Edition" menu.
  9. A good frame rate is between 24 and 30 frames per second. Anything less than 20 frames-per-second will result in choppy motion in the video.
    • Increasing the frame rate beyond the original frame rate will not produce smoother video quality. It will just result in duplicate frames and produce a larger video file. However, Flowframes for Windows and SVP Prohave the ability to interpolate video and add frames to a video.
  10. It's to the right of the box that says "Destination file". This allows you to select a file name for the converted video and a save location.
  11. Use the space next to "File name" to type a new file name for the converted video.
    • You can also navigate to a location where you want to save the video.
  12. It's at the bottom of the File Explorer or Finder menu.
  13. This starts converting the video to a new file at the frame rate you selected.

    Expert Answer
    30 fps is the standard visual experience—it’s what you typically see with regular TV shows and movies. While 60 fps takes things up a bit by creating smoother and more fluid motion. This stands out in fast-paced content, like action games or sports. With 60 fps, the frame transitions are smoother, making everything look more lifelike and “live.” This higher frame rate makes actions and camera movements feel crisper and more responsive, which is why gamers and video enthusiasts love it for a more immersive experience. With that being said, whether 60 fps is worth it depends on what you're watching. For regular videos or casual viewing, 30 fps is perfectly fine and doesn’t feel choppy. But if you’re into gaming, sports, or anything with lots of fast movement, 60 fps can make a big difference and feel easier on your eyes.

    Community Answer
    To change the frame rate in any video editor: Look for "Settings" or "Project Properties." Choose the desired frame rate (e.g., 24fps, 30fps, 60fps). Save settings and adjust the timeline if needed. Be sure the frame rate matches your preference when exporting.
  • Question
    When a program like a video editor changes the frame rate, how does it do it? If we had an infinite frame rate, you could just choose the frames for the desired frame rate. No characters left.

    Community Answer
    Video editors change frame rates by dropping frames (e.g., 60fps to 30fps skips every other frame) or by adding frames via duplication or interpolation (estimating motion to create new frames). This adjusts playback speed without needing infinite frames.
