TEMPORARY MEDIA WORKSPACE / VIDEO ROTATOR

Video Rotator

Rotate every frame clockwise by 90, 180, or 270 degrees and download a newly encoded H.264 MP4.

Request-scoped temporary processingAdd one supported file up to 50 MB. Long or unusually large-frame media may be rejected before processing.No account required

Local API readinessMedia service ready

The processor required by this tool is available, and this worker can accept a temporary job.

One bounded job runs per API worker by default.

Temporary server workspace

The selected bytes are sent only to the Nirmion media API for this request. Processing uses a private temporary workspace rather than permanent catalogue storage.

Request-scoped cleanup

Server-side source and result files are removed when the response stream closes. Re-downloads use the result Blob retained only in this browser tab.

Original stays unchanged

Nirmion writes a separately named result containing nirmion_tools and never overwrites the selected source file.

Know the product contract

What goes in, what changes, what comes back

Every media page documents the accepted source, the selected FFmpeg transformation, the output container, and the limits that can affect the job.

Prepare the source

Check how the source appears in more than one player because some files contain orientation metadata interpreted inconsistently.

Apply one operation

FFmpeg transposes or flips the decoded frames to the selected clockwise angle, then writes the rotated pixels into a new H.264 MP4.

OUT

Receive a separate file

Confirm orientation, width and height, captions, and audio sync in the result.

Plain-language method

How physical video rotation works

Physical rotation improves compatibility but requires re-encoding. It is not a lossless metadata-only edit.

01
Choose valid source media
Check how the source appears in more than one player because some files contain orientation metadata interpreted inconsistently.
02
Review the operation settings
Use 90 for a quarter-turn clockwise, 180 for upside-down footage, or 270 for a quarter-turn counter-clockwise equivalent.
03
Inspect and download the result
Confirm orientation, width and height, captions, and audio sync in the result.

Useful when

Practical jobs this tool handles

Correct a phone clip saved sideways.
Turn an upside-down camera recording.
Normalize orientation before merging several clips.

Before processing

Check the source and output choices first

Verify whether the needed direction is clockwise.
Check captions and logos after rotation.
Expect width and height to swap for quarter turns.
Keep the source until orientation is verified in the download.

Container and codec

Understand the output format

The result is an H.264 MP4 with available AAC audio. Rotation metadata is replaced by physically transformed frames.

Know the boundary

Rotation is applied to the entire timeline

The tool cannot rotate only part of a clip or correct a gradually tilted horizon. It applies one fixed angle to every frame.

Quick answers

Questions before you process media

These answers describe the actual upload, FFmpeg processing, download, and temporary-retention contract.

Is 270 degrees the same as turning left?

Yes. A 270 degree clockwise turn is equivalent to a 90 degree counter-clockwise turn.

Will the frame dimensions change?

A 90 or 270 degree rotation swaps width and height; 180 keeps the same dimensions.

Is this only a metadata change?

No. Frames are physically transformed for consistent playback.
