Questions, answered
How do I know if my video is mirrored?
Find any text in the frame — a logo, a sign, a screen. If it reads backwards, the video is mirrored horizontally. Faces alone will not tell you, because a mirrored face still looks natural.
Why is my selfie video reversed?
Front-facing cameras preview a mirrored image so it feels like a mirror while you record, and some apps save that mirrored version rather than the true one. A horizontal flip restores it.
What’s the difference between flipping and rotating?
Flipping mirrors the image across an axis, producing a reversed picture. Rotating turns the whole frame without reversing it. Mirrored text needs a flip; a sideways video needs a rotation.
Does flipping reduce quality?
Mirroring rearranges existing pixels exactly, so the operation itself is lossless. Only the re-encode of the output file introduces any loss, and at high quality that is not visible.
Can I flip only part of a video?
No — the flip applies to the whole clip. To flip only a section, split the video, flip the part you need, and merge the pieces back together.
