Q: Does rotating video reduce the original video quality?

No. VidDow provides two specialized modes: Fast Metadata Rotation which adjusts orientation tags losslessly in under 0.2 seconds without touching pixel data, and Full Video Transposition which permanently rearranges video frames with pristine quality preservation.

Q: Are my video files uploaded to VidDow servers?

Q: How do I fix a video recorded sideways or upside down on my smartphone?

Simply drag and drop your smartphone video file into the drop zone. Click Rotate 90° CW or Rotate 180° to set the correct upright orientation, verify the result in the live preview window, and click Start to export the corrected video immediately.
