How to Flip a Video for TikTok

The fastest way to flip a video for TikTok is to mirror it horizontally before you upload, then add any on-screen text afterwards so the words don't come out reversed too. Here's how to spot a mirrored clip, and where the flip actually has to happen.

Flip a video for TikTok before it gets to the app

Apple documents a flip control in the Photos crop tools that flips photos and videos horizontally, alongside crop, rotate and straighten. That's a dependable place to correct the image on a phone.

Inside TikTok, the documented frame controls in its editing tools are rotating and zooming individual clips. Useful, but a different operation. Rotating turns the frame; flipping mirrors it. Coming into the app with the image already the right way round avoids finding out which one you have.

The front-camera clip where every word reads backwards

The preview on a front camera is deliberately mirrored, because a preview that moved the "correct" way would feel wrong to look at. What most people never think about is that the mirror can survive into the saved file, and the moment there's writing in shot, it shows. A hoodie logo, a book cover, a whiteboard, the label on the thing you're reviewing: all reversed, all instantly noticeable to a viewer who can't say why the shot feels off.

That's the whole test. No text in frame, no visible problem. Text in frame, flip it.

The clip that never leaves your device

Selfie footage is the most personal thing most people edit, and a mirrored front-camera take is almost always exactly that. Montaj doesn't flip clips, that step happens before it. What it does guarantee is that the footage it works on never leaves your device: transcription, subtitles and audio cleanup all run locally, and the only network call the app makes is a one-time download of its models. If you've flipped a video for TikTok because your face is in it, that's a reasonable thing to care about next.
