Screen recordings, exported meetings, camera footage and course videos are nearly all MP4. Upload one exactly as it is, with no need to pull the audio out first, and download a genuine .docx. Free for your first transcript, in full at any length · packs start at $8 for 1,000 minutes and the credit keeps.
How it works
Only the audio track matters, so resolution changes nothing.
Drop the MP4 into the box above. Larger recordings continue on the upload page, which handles files up to the 5 GB ceiling.
The video sits beside the transcript, so any line can be checked against the moment it came from. Speaker labels show here, on the page.
Choose DOCX, with timestamps or without. Captions in SRT or VTT come from the same transcript and spend no further minutes.
About MP4
MP4 is where the 5 GB ceiling bites, and the way round it takes a minute.
Meeting apps export MP4, and so do screen recorders, phones, cameras and course platforms. It is the standard container for H.264 video with AAC audio.
A 1080p recording runs 1 to 2 GB an hour and 4K several times that. Three hours of 4K passes the ceiling, though the speech inside is a few dozen megabytes.
Export an audio-only version, or use the free extract audio from video tool. The timeline is untouched, so timestamps still match the video.
Spoken words only. Slides and shared screens are not read, so anything shown but never said aloud is not in the document.
| MP4 recording | One hour | Three hours | Inside 5 GB? |
|---|---|---|---|
| 720p screen recording | ~0.5 GB | ~1.5 GB | Yes |
| 1080p meeting export | ~1.5 GB | ~4.5 GB | Only just |
| 4K camera footage | ~10 GB | ~30 GB | No, extract the audio |
Rough figures; encoder settings move them. Audio pulled from any of these is typically 30 to 60 MB an hour.
Common uses
Footage nobody has two spare hours for.
Written minutes from the export: keep the decisions, delete the five minutes of people joining.
Hand attendees something built from what was actually said, not from the slide deck.
A written lesson is searchable and quotable, and a workbook starts from real sentences.
Pull quotes into a research write-up with the timestamp beside each, so a colleague can check it.
Pricing
Cost is counted from how long the recording runs, never from the size of the file, so a 4K video costs what the same conversation would as a voice memo. Your free first transcript covers at any length, read in full.
A 52-minute webinar is $0.42 of the $8 pack, or $0.25 on the $24 pack. Ten of those still fit the smallest pack. See the pricing page.
FAQ
Upload the MP4 here, let the transcript finish, then export DOCX. Preview without signing up; $0.99 opens your first transcript in full.
No, upload the video as it is. Extracting the audio is only worth it when the file is near the 5 GB ceiling or the upload would be painful.
No, only the spoken audio is transcribed. A slide heading that nobody read aloud will not appear in the Word file.
No. The transcript view on this page shows speaker labels beside the lines; the DOCX export contains the words, so any names you need are added in Word afterwards.
Ten hours or 5 GB, whichever arrives first. The box here accepts up to 500 MB and the upload page takes the rest.
Yes. SRT and VTT export from the transcript you already have, so captioning the video costs no extra minutes.
Yes, a standard Word document. Restyle it, add headings, track changes and share it as you would any other file.
Usually not. A recording where one microphone reached a single channel still transcribes; a silent channel means whoever was on it never got recorded.
Instant preview, no signup. Up to ten hours of video per file.
