Video Rotator FAQ
Why does my video play sideways on some devices?
Phones often record in one orientation and add a tag telling players how to rotate. Some players and websites ignore the tag. Rotating the pixels here removes the ambiguity.
Which direction should I choose?
Look at the preview: choose the option that makes the picture upright. If the top of the scene is on the left side of the screen, choose 90° clockwise.
Does rotating reduce quality?
The video is re-encoded to apply the rotation, which uses normal compression. At the default setting the difference is very small.
Can I rotate by a small angle to straighten the horizon?
This tool rotates in 90° steps. Straightening by a few degrees requires cropping the edges, which is a job for a full video editor.
Will the video’s resolution change?
A 90° rotation swaps width and height: a 1920 × 1080 video becomes 1080 × 1920. A 180° rotation keeps the same size.
Rotation tags versus rotated pixels
Phones contain sensors that know how they are held, but their cameras always record in the sensor’s native orientation. To avoid extra processing, the phone writes the video as recorded and adds a display-rotation tag to the file. Players that understand the tag turn the picture on playback; players that do not, show it sideways.
That explains the common experience of a video looking fine on the phone that recorded it and sideways after being emailed, uploaded or opened on a computer. Changing only the tag is instant but leaves the problem for the next player that ignores it. This tool rotates the actual pixels with FFmpeg’s transpose filter and clears the tag, so there is only one way to display the result.
Rotating by 90° changes the frame from landscape to portrait or vice versa. If the video needs to fit a particular screen afterwards, for example a 16:9 TV, combine rotation with the Video Resizer, which can add bars or a blurred background to fill the frame.
Upside-down footage is common with action cameras, dashcams and drones mounted under a surface. A 180° rotation fixes it and also corrects left-right orientation, so text in the scene reads normally.
