Frequently Asked Questions (FAQ)
Q: Can this tool fix backwards text from a selfie camera?
A: **Yes, absolutely!** If your front-facing camera mirrored your video and the text is unreadable, simply use the "Horizontal Flip (Mirror)" option to reflect it back to normal.
Q: Will my personal videos be uploaded to your server?
A: **No uploads whatsoever.** We utilize local client-side processing. The entire rotation process happens inside your computer's browser, meaning your private videos are 100% safe.
Q: Will I lose audio or video quality when rotating?
A: Our tool is designed to **copy your original audio track** seamlessly while re-encoding the video frames at a balanced bitrate. This ensures your final clip retains excellent visual quality without losing any sound.
Q: Why did my browser crash when rotating a large file?
A: Since the tool uses your device's RAM to process the video, files larger than 250MB might exceed your browser's memory limit (Out of Memory error). **Quick Fix:** We recommend using our Video Compressor tool to reduce the file size before rotating.
