Example
Example: a selfie clip with a “Thank you, Miss Khan!” card that reads backwards
Parents are collecting clips for a teacher’s leaving video. One, filmed on the front camera, shows a mum holding a card that says “Thank you, Miss Khan!”, and in the saved video the words are back to front. thanks.mp4: portrait, 1080 × 1920, 20 seconds with sound. Settings as the page opens: Keep the shape, Mirror left to right.
- Every frame is mirrored left to right: the card reads normally again, and the hand holding it moves to the other side, as other people see her.
- The picture is encoded again as H.264 at 1080 × 1920 and 30 frames a second, at about 10 Mbit/s: roughly 25 MB for 20 seconds, plus the sound, which is copied unchanged.
- A portrait clip stays portrait: the turn the phone records in the file is drawn into the picture.
- A 4K clip (2160 × 3840) comes out at 1080 × 1920, since the long side is capped at 1920; a 60 fps clip keeps 60 fps, at about 20 Mbit/s.
| Clip | Settings | Comes out as |
|---|---|---|
| Portrait 1080 × 1920, 30 fps | Keep the shape, Mirror left to right | thanks-flipped.mp4, 1080 × 1920, about 10 Mbit/s |
| Portrait 4K, 2160 × 3840 | Keep the shape, Mirror left to right | …-flipped.mp4, 1080 × 1920 |
| Portrait 1080 × 1920, 60 fps | Keep the shape, Mirror left to right | …-flipped.mp4, 60 fps, about 20 Mbit/s |
| Landscape 1920 × 1080 | Vertical 9:16, The middle, Mirror left to right | …-cropped.mp4, 608 × 1080 |
thanks-flipped.mp4: still portrait, the card readable, the sound as it was. On a typical computer it takes about as long as the clip lasts, 20 seconds here, and the free plan takes 3 clips in one run.
How it works
- Drop an MP4 or MOV onto the box.
- Keep "Mirror left to right" to undo a front-camera mirror, or choose upside down.
- Select Flip video and download the MP4.
Frequently asked questions
- Why is my video mirrored?
- Front cameras show you as in a mirror, and some apps save the clip that way, so text and logos read backwards. Mirroring it again puts them the right way round.
- Is flipping the same as rotating?
- No. Rotating turns the picture a quarter or half turn; flipping mirrors it. For a video on its side, use Rotate video, which is instant and needs no re-encoding.
- How long does it take?
- The picture is decoded and encoded again as H.264 at a high bit rate (up to 1920 pixels on the long side), which takes about as long as the video lasts on a typical computer and needs Chrome, Edge or Safari 16.4 or newer. The sound is copied as it is. That holds for AAC sound, which phones record; another kind (PCM in a camera MOV) is left out, and the result says so.
- Mirror or upside down: which one do I need?
- Mirror left to right when writing reads backwards. Upside down flips the picture top to bottom, like a reflection in water, and leaves writing mirrored too. A clip that is simply the wrong way up was turned rather than flipped: Rotate video at 180° puts it right without re-encoding.
- Will the flipped video be bigger than the original?
- It can be. The picture is encoded fresh at about 10 Mbit/s for 1080 × 1920 at 30 fps, roughly 75 MB a minute, whatever the original’s bit rate, so a clip the phone saved at a lower rate grows. Put it through Compress video afterwards if it has to be small.
- Is the video uploaded, and what are the free limits?
- Nothing is uploaded. The free plan allows 3 videos of up to 150 MB per run and 5 runs a day. Pro removes these limits.
