About the
The Video Transformer flips, rotates and reverses video in your browser. Horizontal and vertical mirroring fixes footage shot through a mirror or upside-down action cams; 90/180/270-degree rotation saves videos recorded in portrait; reverse plays the clip backwards with audio reversed to match.
All transforms are combined into a single ffmpeg filter chain and encoded once, so applying several effects does not degrade the video repeatedly. Processing is fully local.
This is the tool for fixing orientation before posting, creating a mirror effect for a dance or transition edit, or producing the classic reverse-footage look.
Where people use the
- Fixing portrait or upside-down footage before posting.
- Creating a mirror effect for choreography and transitions.
- Producing reverse-motion clips for comedy or drama.
How to use the
- 1
Add a video
Drop in a clip and preview it in the player.
- 2
Stack transforms
Toggle flip H, flip V, rotate (each click adds 90 degrees) and reverse. Combine as many as you need.
- 3
Apply and export
One encode applies the whole chain. Watch the progress bar.
- 4
Download
Preview and download the transformed MP4.
Tips and best practices
- Fix orientation first when combining transforms; the chain handles it in one encode either way.
- Reverse needs audio re-encoded, so it takes slightly longer than visual-only transforms.
Frequently asked questions
Can I combine several transforms?
Yes. Flip plus rotate plus reverse all apply in one pass, with a single encode.
Does reverse work with audio?
Yes, the audio track is reversed too, so speech and effects play backwards in sync.
Why does rotate change the dimensions?
A 90 or 270-degree rotation swaps width and height; that is expected. 180 keeps the frame size.
Is quality lost?
Only the single re-encode to H.264 at a high-quality preset. No repeated generation loss.
