How to transcribe an MP4 to text
To transcribe an MP4, load the video into a transcription tool that accepts video files (Word's Transcribe, YouTube's automatic captions, an online service, or a desktop app like Hark), and it will turn the audio track into text. You don't need to convert the MP4 to an audio file first.
What "MP4 to text" really means
An MP4 is a container that holds a video track and an audio track. Transcription only uses the audio: the tool listens to the speech and writes it down. So the same things that make audio easy or hard to transcribe apply here: a clear microphone, little background music, and people taking turns.
Common MP4s people want transcribed: recorded Zoom, Teams or Meet calls, webinars, screen recordings, lectures, phone videos and interviews.
Video files are also big. An hour of meeting video can be hundreds of megabytes, while the same hour of audio is a fraction of that. That matters for online tools, where uploading is often the slowest step and file-size limits are common. Tools that run on your own computer read the file where it is, so size only affects how long the import takes, not whether it's allowed.
Option 1: Hark (free, on your computer)
Hark is a free desktop app for Windows, Mac and Linux. It imports video files (MP4, MOV, WebM and others), takes the sound from them, and transcribes it locally. It's a transcription tool, not a video editor: you get the transcript, speakers and audio player, not video playback.
- Download Hark and sign in with a free account (an emailed code; no card).
- Drag the MP4 onto Hark, or choose File > Import.
- On first use, Hark downloads its speech models (about 730 MB). After that it works offline.
- Hark transcribes the audio and separates the speakers.
- Name each voice once. Hark recognizes those people in future recordings and imports.
- Fix any lines, then export the transcript or write your own notes next to it.
Good to know: Hark is English only, has no limits on file length or number of files, and never uploads your video or audio for transcription.

Import an MP4 or MOV and Hark transcribes its audio on your computer, with each speaker named. Free and unlimited.
Option 2: Word's Transcribe
Word for the web and Word for Microsoft 365 on Windows accept MP4 uploads in the Transcribe pane.
- Choose Home > Dictate > Transcribe.
- Select Upload audio and pick the MP4.
- Wait with the pane open; it can take about the length of the video.
- Rename the speakers and add the transcript to your document.
It needs a Microsoft 365 subscription, and as of October 2026 there's a monthly allowance of 300 minutes of uploads. Large videos take a while to upload.
Option 3: YouTube's automatic captions
If you don't mind uploading to Google, YouTube creates automatic captions for many videos in supported languages.
- Upload the MP4 to YouTube as Private or Unlisted.
- Wait for processing, then open the video in YouTube Studio and go to Subtitles.
- Open the automatic captions and copy the text, or edit them first.
It's free and handles many languages, but it's slow for long videos, doesn't label speakers, and the video lives on Google's servers. Not ideal for internal meetings.
Option 4: Online services and video editors
Online transcription services and video editors with auto-captions are the best choice when you need subtitles (SRT or VTT files), many languages, or human-checked accuracy. They're strong products; the trade-offs are cost after the free tier, upload time for big videos, and privacy, since your recording goes to their servers.
Should you extract the audio first?
Only if a tool won't accept video, or a video is too big to upload. A free media player such as VLC can convert an MP4 to an audio-only file. Audio files are much smaller, so they upload faster. Then follow our MP3 to text guide. Tools that read video directly, like Hark, skip this step.
Transcribing recorded meetings
Meeting recordings are the trickiest MP4s: several people, laptop microphones, interruptions and the occasional dog. A few things help:
- Use the meeting app's own transcript if it made one. Zoom and Teams can transcribe during the meeting when that's turned on. See how to transcribe a Zoom meeting.
- Name speakers right away. It's easiest while you still remember who said what.
- Next time, record the audio directly. On Windows and Linux, Hark records your mic and your computer's audio as separate tracks while the meeting happens, with no bot in the call. That gives cleaner audio than a recorded video, and a live transcript as you go. On a Mac, Hark records the microphone only.
Recording laws vary by place and some require everyone's consent, so let people know before you record a meeting.
Which option fits your video?
| Your video | Good choice |
|---|---|
| Internal meeting or interview, in English | Hark: local, speaker names, no limits |
| Short clip, you already use Microsoft 365 | Word's Transcribe |
| Public video that needs captions | YouTube captions or a subtitle tool |
| Not in English | An online service that supports the language |
| Legal or broadcast use | A human transcription service |
Accuracy tips for video transcripts
- Background music hurts. If you can, transcribe the version of the video before music was added.
- Check proper nouns. Product names, places and people are the most common mistakes.
- Watch speaker changes. Short replies like "yes" or "right" are often given to the wrong person; here's why.
- Proofread quotes against the audio before you publish them.

Frequently asked questions
How do I transcribe an MP4 video to text? +
Open the MP4 in a transcription tool that accepts video files. Word's Transcribe accepts MP4 uploads with Microsoft 365, many online services do too, and Hark imports MP4 and MOV files and transcribes their audio on your computer for free (English only). There is no need to extract the audio yourself first.
Can I transcribe an MP4 for free? +
Yes. Hark is free with no limits and transcribes on your own computer. YouTube also generates automatic captions for uploaded videos, which you can view and copy from YouTube Studio, though that means uploading the video to Google. Online services usually have small free allowances.
Do I need to convert MP4 to MP3 before transcribing? +
Usually not. Most transcription tools read the audio track from an MP4 directly. Converting only helps if a tool accepts audio files alone, or if the video is too large to upload; then a free player like VLC can save just the audio.
How do I transcribe a recorded Zoom or Teams meeting video? +
Zoom and Teams can make their own transcripts if transcription was turned on during the meeting. If you only have the MP4, import it into a transcription tool. Hark splits the transcript by speaker and lets you name each voice.
Can I get subtitles (SRT) from an MP4? +
Many online services and video editors export SRT or VTT subtitle files with timing. Hark exports transcripts and notes, not subtitle files, so pick a subtitle-focused tool if captions are your goal.
