How to Rotate a Video with FFmpeg?

On Windows, navigate to the directory path of the video you want to rotate and type cmd in the address bar. Then, press the Enter key to open the command prompt window.

On Mac or Linux, open Terminal and press the Return key to run the command you input.

Now, input a command to let FFmpeg rotate your video. As mentioned above, you can use three different FFmpeg filters to rotate the input video. Here is how to use them in the command:

–– Via the transpose filter

transpose can help you rotate a video 90 degrees clockwise or anti-clockwise and flip a video horizontally or vertically. This filter accepts values from 0 to 3. What do the values present?

0 = 90° counterclockwise and vertical flip
1 = 90° clockwise
2 = 90° counterclockwise
3 = 90° clockwise and vertical flip

For instance, you can run this command to rotate a video 90 degrees clockwise ↻:
ffmpeg -i input.mp4 -vf "transpose=1" output.mp4

• Replace "input.mp4" and "output.mp4" based on your actual circumstance.

You can also combine multiple transpose filters to change the orientation of the video, such as flipping by rotating 90° twice:
ffmpeg -i input.mp4 -vf " transpose=1, transpose=1" output.mp4

–– Via the rotate filter

rotate offers more flexibility and allows you to rotate a video to any precise angles expressed in radians.

For example, rotate a video 180° (by π/1 radians) with this command:
ffmpeg -i input.mp4 -vf "rotate=PI:bilinear=0" output.mp4

• "PI" refers to π, and "bilinear=0" can make the video not blurry.

Alternatively, you can use degrees instead of radians. E.g. Rotate a video 45°:
ffmpeg -i input.mp4 -vf "rotate=45*(PI/180)" output.mp4

–– Via the hflip and vflip filters

hflip flips a video horizontally while vflip flips the video vertically.

This command will flip your video horizontally:
ffmpeg -i input.mp4 -vf "hflip" output.mp4

Of course, you can combine the two filters to rotate it horizontally and vertically:
ffmpeg -i input.mp4 -vf "hflip, vflip" output.mp4

Install and launch Free HD Video Converter Factory on your desktop. Then, click Converter > + Add Files to import the video you want to rotate. Drag-and-drop is also supported.

Click the rotate ⟲ icon below the source video to bring a new window. You can click the play button to preview/pause the video.

Next, select a rotating method (90° clockwise, 90° anti-clockwise, horizontal flip, or vertical flip) and adjust the video orientation as desired.

Once done, press OK to save your change.

Tap the format image on the upper right side of the interface and choose an output format (e.g., MP4) from the Video tab. Then, click the ▼ button at the bottom to select a destination file path.

Finally, click Run to export the final video files.
