When a video shot on your phone plays in the wrong orientation, this tool quickly fixes the screen direction. It uses underlying FFmpeg calls to perform frame-level affine transformations in the YUV color space, supporting 90°, 180°, and 270° clockwise rotations as well as mirror flipping. It strictly maintains the original GOP structure and B-frame dependencies to avoid secondary compression distortion.
Q: Why can't my AVI file be rotated?
A: Some older AVI formats use non-standard codecs. We recommend converting them to H.264 encoded MP4 files first.
Will the video quality drop after rotation?
No. This tool uses lossless rotation technology, strictly preserving the original frame rate and keyframe structure.
Please do not upload copyrighted videos. Large files over 500MB may cause processing failures. Some special encoding formats may not be supported.
For professional users who need precise control over rotation angles, we recommend checking the video metadata before rotating. Typical example: When a 1080×1920 portrait video is incorrectly tagged as landscape, selecting a 90° clockwise rotation will output the correct 1920×1080 resolution.
