GhostVideoStudio

Rotate video, privately.

Turn a sideways or upside-down clip the right way up — baked into the file, on your device.

Rotate a video in your browser — turn a sideways phone clip upright, spin a 90° or 270°, or flip an upside-down recording to 180°. GhostVideo re-encodes the clip with ffmpeg compiled to WebAssembly, baking the rotation into the video stream and outputting a web-standard MP4 (H.264 + AAC) that displays the right way up in every player and editor — not just the ones that happen to honor rotation metadata. The file never leaves your device, so a private recording rotates without touching a server. No upload, no watermark, no signup, and no length cap beyond your device's memory.

How it works

  1. 1

    Drop your video

    Drag an MP4, MOV, or WebM onto the page or click to browse. It opens in the GhostVideo studio with Rotate pre-selected — nothing is uploaded.

  2. 2

    Pick the rotation

    Choose 90° (quarter turn right), 180° (upside down), or 270° (quarter turn left) to get the clip the right way up.

  3. 3

    Download the rotated video

    ffmpeg bakes the turn into the video on your device and the corrected MP4 downloads from your browser — playing upright everywhere.

Frequently asked questions

  • How do I fix a video that plays sideways?

    Drop it here, choose 90° or 270° until it's upright, and download. GhostVideo bakes the rotation into the video stream, so it displays correctly in every player — not just apps that read rotation metadata.

  • Is my video uploaded to rotate it?

    No. ffmpeg runs inside your browser via WebAssembly, so the clip is never sent to a server. Nothing but the engine download touches the network.

  • Does rotating re-encode the video?

    Yes — the frames are physically turned and the clip is re-encoded to H.264 MP4 at near-source quality. That's what makes the rotation permanent and universally visible, rather than a metadata flag some players ignore.

  • Can I turn a video completely upside down?

    Yes — pick 180° to flip a clip that was recorded upside down back to normal.

  • Why do my phone videos come out sideways in the first place?

    Phones record in one orientation and store a rotation flag telling players how to display the footage. Some editors and platforms ignore that flag, so the clip looks sideways — baking the rotation in with this tool removes the ambiguity.

Every GhostVideo tool runs entirely in your browser. Your file is never uploaded — there's no upload endpoint to send it to.
