A video can appear in the wrong orientation after recording or transferring it between devices.
Rotation lets you correct the viewing direction before sharing or publishing the file.
Choose the correct angle
Common corrections use 90, 180 or 270-degree rotation.
Check aspect ratio
Rotating a landscape video into portrait swaps the effective width and height.
Inspect text and overlays
Make sure captions and visual elements are also oriented correctly.
Test the final file
Play the result on the device or platform where it will be used.
Why can video orientation be wrong?
Some phones store orientation information as metadata instead of permanently rotating every frame. One application may interpret that information correctly while another application may ignore it.
This explains why a video can look normal in the phone gallery but appear sideways when uploaded to another service.
Choose the correct rotation angle
A sideways video normally needs a 90-degree rotation, while an upside-down recording usually requires 180 degrees. Use visible clues such as faces, signs and captions to determine the correct direction.
Preview the result before exporting instead of rotating the file several times unnecessarily.
Rotation versus changing the video shape
If the content itself is sideways, rotation is the correct operation. If the video is already upright but you want to convert a landscape composition into a portrait frame, that is a different task and may require cropping or resizing.
Understanding the difference prevents unnecessary editing.
Check dimensions after rotation
Rotating a landscape video to portrait changes the effective width and height. This can matter when the destination platform requires a specific aspect ratio.
Inspect important text, faces and graphics near the edges before deciding whether additional cropping is necessary.
Test the exported file
Play the finished file outside the editing tool as well. Check that the orientation remains correct and that the audio is still synchronized.
Keep the source video until the exported copy has been tested successfully.
A practical orientation example
Imagine a phone recording that appears sideways when opened on a computer. Rotate it 90 degrees and check whether faces, signs and captions now appear naturally upright. If they do, no additional rotation is needed.
After export, open the file in another player as well. The important result is not only that the preview looks correct, but that the saved video keeps the correct orientation wherever it will be used.
Correct orientation before other major edits
When possible, fix a video's orientation before adding text, overlays or precise crops. Editing a sideways video first can make later positioning harder and may require additional adjustments after rotation.
Working in the correct orientation from the beginning makes the rest of the editing process more predictable.

Choose settings based on where the file will actually be used rather than simply aiming for the smallest size or the highest possible dimensions. Keep your original file, review the processed result and choose a format that suits your final destination.
