Questions
Is my video uploaded anywhere?
No. The video is processed by your own browser, on your own device. It is never sent to a server, so it stays private.
Does it reduce video quality?
No. The picture is copied as is and only the sound is changed, so it finishes quickly with no quality loss.
What if my audio is longer or shorter than the video?
Longer audio is cut at the end of the video. Shorter audio is followed by silence, or repeated if you turn on Repeat.
How big can the video be?
Up to 500 MB. Everything runs in your browser’s memory, so very large files can be slow or fail on older phones. Shorter clips work best.
Why is the first run slow?
The first time, your browser downloads the video engine (about 10 MB). After that it is cached and starts quickly. Processing speed depends on your device.
