Compare videos side by side or with a wipe

Open two videos and see both at the same time, in sync: side by side or with a wipe you drag to reveal one over the other. It serves to compare an original and an edited version, or two compressions. All in the browser, without sending the files.

Video 2 (right)

How to do it, step by step

Choose video 1 (left) and video 2 (right).

Tips for a good result

Only video 1 produces sound, so the audio does not mix.
The wipe is only available once both videos are chosen.

What this tool does not do

This page only compares on screen: it does not generate a new file.
It only accepts videos.
Everything happens in the browser: performance depends on the device.

Frequently asked questions

Do the two videos play in sync?: Yes. The app repositions video 2 when it drifts from video 1 by more than a fraction of a second.
Can I export the comparison?: No. To join the two into one file, use the join videos page.
