浏览器内运行这个工具能做什么
Apply a visible pixel rotation and re-encode the video, rather than only changing a player-dependent rotation metadata flag.
Processing starts only after you choose files and press the action button. The media engine is not preloaded on the homepage or ordinary tool pages.
这个工具可以完成什么
Rotate pixels clockwise so players that ignore orientation metadata still display correctly.
依赖结果前需要检查什么
- Re-encoding is lossy and can change color or compression characteristics.
- Existing rotation metadata may already affect displayed dimensions; inspect with Media Info first.
如何使用
- 1
Choose the video file from your device.
- 2
Review the detected media facts and task-specific controls.
- 3
Start the local job, watch progress, or cancel to terminate the worker.
- 4
Play or inspect the downloaded result before replacing the source.
使用场景
Rotate pixels clockwise so players that ignore orientation metadata still display correctly.
Inspect current rotation, choose the pixel transform, encode, and test in more than one player.
使用技巧
Confirm codec and browser support before committing device time to a long source.
Every output is a new file. Retain the original until you have completed a full playback check.
常见问题
Is my media uploaded to TOOLGRID?
No. The selected files are written into an in-browser worker file system. The self-hosted encoder assets are downloaded separately, but TOOLGRID does not receive the selected media for processing.
Why can a local media job be slow?
The compatibility encoder runs single-threaded in WebAssembly and is limited by device CPU, available memory, source duration, resolution, codecs, and browser behavior.
What should I verify in the result?
Check playback, duration, seeking, video and audio synchronization, expected tracks, visual quality, and actual file size in the browser or player used by your audience.
