How to Flip a Video for Instagram

The fastest way to flip a video for Instagram is to mirror it before you import it. Instagram's clip-editing tools don't include a flip. Here's how to tell whether you need one, and what to check on the way out.

Flip a video for Instagram: where the in-app tools stop

Instagram documents its reel clip-editing tools as Scale, Crop, Rotate, Undo and Redo. It's a short, sensible list that covers framing and orientation.

Mirroring isn't framing or orientation, and it isn't on the list. This trips people up because Rotate looks like it should be adjacent, but rotation turns an image around its centre and a mirrored clip stays mirrored no matter how many quarter-turns it takes. Left and right have been swapped, and only flipping swaps them back.

So the operation happens before Instagram sees the file.

The front-camera clip where every word reads backwards

The reason anyone needs this is almost always the front camera. Its preview is mirrored on purpose. It behaves like a looking glass, so raising your right hand raises the hand on the right of the screen, which is what makes framing yourself possible at all.

The consequence shows up in text. A logo on your shirt, a sign behind you, writing on a whiteboard: all reversed relative to what you saw while filming. That's the diagnostic. If there's readable text in shot and it reads backwards, the clip is mirrored. If there's no text in shot, the mirroring is genuinely invisible to everyone except you.

Check the frame after the flip

One detail worth knowing: Meta's design specifications allow an aspect ratio tolerance of just 1%. A flip shouldn't change dimensions at all, but some tools re-encode and re-frame in the same pass, and a clip that comes out fractionally off-ratio is exactly the sort of thing that gets quietly cropped on upload.

Quick check of the exported dimensions, and you're done.

Flip, look, flip back

The awkward thing about mirroring is that it's hard to judge in the abstract. You look at a flipped version of a face you know and something feels wrong without you being able to say what.

Montaj gives you 100 levels of undo, which sounds like a housekeeping feature and is really permission to experiment. Try it, watch it, change your mind, change it back, and the source media is untouched throughout. Editing happens vertically in 9:16 with the preview at the same proportions as the export, so what you're judging is the real frame rather than a small approximation of it, and the export is 1080×1920 with no watermark, on your device, nothing uploaded. When you flip a video for Instagram, being able to undo the decision fifty times is worth more than getting it right first.
