To fix a sideways video, rotate it 90 degrees in the right direction and save it. The catch is that many apps only save a rotation note in the file, which some players and websites ignore, so the video still shows sideways somewhere else. To fix it permanently, export it from the MobileStudio Rotate & Flip Video tool, which rotates the actual picture.
The short answer
| Where it looks sideways | Fix |
|---|---|
| On your own phone | Rotate it in Photos or Google Photos |
| On a Windows PC or website, but fine on your phone | Bake the rotation in with the browser tool |
| Upside down | Rotate 180° (two 90° turns) |
| Mirrored and sideways | Rotate, then flip horizontally |
Why do videos end up sideways?
Phone cameras always capture the sensor the same way and add a note to the file saying how it should be displayed. The note is set when recording starts. If the phone was flat, tilted, or had rotation lock on at that moment, the note is wrong. And even a correct note gets ignored by some older players, Windows apps, editors, and upload forms, which then show the raw, sideways picture.
How do I fix a sideways video permanently?
- Open Rotate & Flip Video on your phone or computer.
- Drop in the sideways video.
- Click Left 90° or Right 90° until the preview is upright.
- Click Export MP4.
The exported video has the rotation applied to every frame, with no orientation note left to be misread. It plays upright in every app, browser, and editor. The sound is kept.

The upload service processed the raw picture without the orientation note, or the note was lost when the file was copied or converted. Bake the rotation in with the browser tool and upload the new MP4.
How do I stop videos recording sideways?

Is a sideways video the same as a vertical one?
No. A sideways video has people lying on their side. A vertical video is upright but tall. To turn a normal landscape video into a vertical one, crop it instead; see how to make a video vertical.
