MP4 to text without extracting the audio
MP4 to text means turning what is said in a video straight into a transcript and subtitles. Most transcription tools accept audio only, which turns the job into: export audio, upload, transcribe. That first step wastes time and re-encoding loses a little audio quality, which can work against recognition accuracy.
Here the video goes in directly. MP4, MOV, MKV and WebM all work; the audio track is handled for you.
What comes back
One upload, three outputs:
- A transcript — 90+ languages detected automatically, no language to select
- Word-level timestamps — start and end times per word, to 0.01s
- Speaker labels — up to 32, on by default
Tested on an English ad read, unedited response:
Vlog narration is the bread and butter of MP4 to text: fast, full of filler words, switching topics mid-sentence:

The script ends "Ships free, today." and came back as "Ships free today" — the comma and full stop were dropped. Punctuation is the least stable part of any transcript because it is inferred from pauses, and pauses vary by speaker. It makes no difference to subtitles; it needs a pass for a formal document.
When the file is too big
The per-upload limit is 200MB. An hour of 1080p footage will blow past that.
The easy fix: export an audio-only file and upload that. Transcription never touches the picture, and an hour of MP3 is typically 60–120MB.
So the default for MP4 to text is to upload the video as it is; exporting audio is only worth the extra step when the file is over the limit.
There is one ordering trap: lock the edit, then transcribe. Transcribing and then re-cutting the video leaves the SRT misaligned against the new picture, and there is no fixing it except to run it again.
What people use MP4 to text for
| Goal | How it works |
|---|---|
| Subtitling a finished cut | Export the SRT, drop it into CapCut or Premiere, already aligned |
| Turning video into an article | Use the transcript as a first draft for a blog or newsletter |
| Clipping long video | Search the text to find the moment, cut on word boundaries |
| Interview write-ups | Speaker separation gives you a dialogue transcript with no re-listening |
| Studying competitor content | Make a long video searchable instead of scrubbing through it |
The second row is the most underrated. A video's transcript is very nearly the first draft of an article, and search engines cannot read speech — publishing the text opens a second door to the same content.
A worked example: one interview, a video and an article
Say you recorded a two-person conversation as an MP4 and want to publish both the video and a written version:
- Lock the edit, then upload the finished video as it is — no audio export.
- When the transcript is ready, replace speaker_0 and speaker_1 with your guests' names.
- Proofread names, product terms and punctuation — punctuation is inferred from pauses, so a published article needs it fixed.
- Export the SRT for the video's subtitles, then shape the transcript into the article.
One upload gives you the subtitles and the first draft of the article, instead of two separate jobs.
How to convert MP4 to text
- Open the voice studio → transcribe
- Upload the video directly (200MB total; export audio-only if it is larger)
- Wait — an hour of material is typically one to two minutes
- Fix wrong words, replace speaker labels with names, export the transcript or SRT
Audio-only files are covered on MP3 to text; if all you need is captions, see the subtitle generator.
FAQ
Do I have to convert the video to MP3 first? No. Upload MP4, MOV, MKV or WebM directly and the audio track is handled for you. Converting first wastes time and re-encodes the audio, which loses a little quality and can slightly hurt recognition.
Video files are large. Is 200MB enough? If it is not, export an audio-only file and upload that instead. Transcription only uses the audio track — the picture has no effect on the result — and an hour of MP3 is usually 60–120MB where an hour of 1080p video can be several gigabytes.
Will MP4 to text subtitles line up in my editor? Yes. The SRT timings come from the word-level timestamps computed during transcription and share the video's time base, so no alignment pass is needed. One caveat: if you re-edit the video after transcribing, the timings will no longer match. Lock the edit first, then transcribe.
Can it separate multiple speakers in the video? Yes. Speaker separation is on by default for up to 32 people, and every line carries a speaker label and timing, so interview and panel footage comes back already shaped as dialogue.
