Rotate & Flip Video Online: Fix Orientation Instantly

Video Rotator — Fix Sideways, Upside-Down, and Mirror-Flipped Footage

Orientation errors in video are more common than in any other media type because phones record video with physical orientation sensors that do not always agree with the recording application's orientation lock. A phone held vertically records portrait video; held at 90 degrees records landscape. A video recorded by someone holding the phone upside down records at 180 degrees. Files exported from some cameras embed a rotation flag in the metadata rather than rotating the actual pixel data — these files display correctly on devices that respect the flag but sideways on players that ignore it. Rotation re-encodes the video with corrected pixel orientation that plays correctly everywhere regardless of player metadata support.

Horizontal and vertical flip operations serve distinct use cases from rotation. A selfie camera video shows a mirrored version of what the subject actually looks like — text and logos in the frame appear reversed. Flipping the video horizontally corrects the mirror artifact without changing the orientation. A teleprompter recording shows text in the correct reading direction on the teleprompter but mirrored in the video feed behind the talent. Vertical flip corrects footage that was mounted upside-down on a ceiling rig or in an underwater housing. The video rotator provides 90, 180, and 270 degree rotation alongside horizontal and vertical flip as independent operations.

Rotation combined with cropping addresses the black bar problem. Rotating a 16:9 landscape video 90 degrees produces a 9:16 portrait video with black triangular bars in the corners where the original frame corners now fall outside the rotated frame boundary. Filling these areas with black letterbox bars is the simplest approach. Cropping to remove the black areas produces a portrait video without bars but with reduced field of view — the original frame corners are sacrificed. The advanced rotator provides both fill and crop modes so the output matches the intended display context.
