M4V is Apple's MP4-based video format, used for iPhone and Mac exports and Apple video apps. Upload a .m4v file and Scriptivox turns the speech in it into an accurate transcript with timestamps and speaker labels, which you can edit and download as TXT, DOCX, PDF, CSV, SRT or VTT.
M4V files come from Apple TV and iTunes exports, HandBrake conversions and some Apple apps. Find the .m4v file in Finder or your Movies folder, 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 the transcript with timestamps, correct any word in the editor, then download it as TXT, DOCX, PDF, CSV, SRT or VTT.
