About MP4 videos
SonaFact transcribes the sound of the video; the picture is not analysed. You do not need to extract the audio yourself — upload the MP4 as it is.
Three steps from recording to finished work
- Upload anything recorded. Audio or video — up to 30 minutes per file on Free, 3 hours on Starter, 6 on Pro and 10 on Studio. The language and the number of speakers are detected for you, or you set them yourself when you already know. You can also record straight in the browser.
- Review in the editor. Play it back with the line highlighted, fix a word, rename a speaker everywhere, move a line to the right person.
- Turn it into finished work. Export DOCX or PDF, generate minutes, action items, subtitles, chapters or a call report.
