AVI is Microsoft's long-standing video container, common in older camcorder footage, archives and Windows screen recorders. Upload a .avi file and Scriptivox turns the speech in it into timed WebVTT captions, the subtitle format HTML5 video players and most course platforms use.
AVI files come from older cameras, Windows video tools and screen capture software. Copy the .avi file from the camera's card or your PC, then upload it.
Leave it on auto-detect or pick one of more than 100 languages. Turn on speaker recognition when more than one person talks.
Read every line in the editor, fix any word, then download the .vtt file, ready for YouTube, your video editor or your player.
