Frequently asked questions
Is my video or audio uploaded?
No. Speech recognition and every edit run in your browser on your own device. Nothing is sent to a server.
Can the subtitles be turned off later?
No, burned-in captions are part of the picture. Keep the SRT file if you also need switchable captions.
Which languages are supported?
Around 99 languages, including English, Spanish, Hindi, French, German, Portuguese, Japanese, Chinese and Arabic. The language is detected automatically, or you can choose it. You can also translate the speech into English captions.
What if a word is wrong?
Click the word and type the fix. Its timing stays the same, so word-by-word caption styles still line up. Find & replace fixes a name everywhere at once.
