About Rotate Video
Rotate Video turns a video 90 degrees clockwise, 90 degrees counter-clockwise or 180 degrees, or flips it horizontally or vertically, then saves it as an H.264 MP4. The rotation is applied to the actual pixels, so the video plays the right way up everywhere.
When it helps
- Fixing a phone video that plays sideways because the phone was held in the wrong orientation.
- Turning upside-down footage from a mounted action or dash camera.
- Mirroring a selfie-camera recording so that text and gestures read correctly.
- Rotating a portrait clip into landscape for a presentation or editing timeline.
Tips
- Use 90 degrees clockwise if the top of the picture currently points left, and counter-clockwise if it points right.
- Flip horizontal is a mirror image, not a rotation. It is useful for front-camera footage where writing appears backwards.
- A 90-degree rotation swaps width and height, so a 1920x1080 video becomes 1080x1920.
