Made for real work
A clear path from recording to finished work.
BriefVox reads the audio track from your MP4 and converts it into a transcript — there is no need to extract the audio yourself. Review the result in the editor, rename speakers, fix the text and export it as a document or a subtitle file.
From MP4 video to editable transcript
Upload the MP4 and BriefVox processes its audio into a transcript with timestamps and speaker labels. Everything happens in the browser: correct the wording, click a line to jump to that moment in the video, and keep the text clean before export.
Built for video creators and teams
Use MP4 to text when you need subtitles, a video summary, a meeting record, training notes or a searchable version of your footage — YouTube videos, recorded meetings, online courses, webinars, product demos and interviews.
Export subtitles from MP4
If you publish video, export SRT or VTT subtitle files and drop them straight into YouTube, an editor or an online player. Timestamps are kept accurate so the captions line up with the picture.

Yes. You can export SRT and VTT subtitle files after the transcript is ready.
Does MP4 transcription include timestamps?+
Yes. Transcript segments include timestamps, which also make subtitle export possible.
Can I edit the transcript before exporting?+
Yes. Correct the transcript in the online editor before downloading TXT, DOCX, SRT or VTT.
