Workflow
How to transcribe MP4 to text
Begin with a downloaded recording you have permission to process. This converter accepts an MP4 file, not a web address. Keep your original video available: the transcript records spoken words, while slides, gestures and on-screen labels remain in the source.
- 1
Select the saved MP4.
Choose the file from your computer or phone. The browser inspects its audio before preparing the upload. A filename ending in MP4 describes a container, so the sound inside still needs a supported codec. If inspection fails, try a fresh export from your recording app.
- 2
Wait for audio preparation and transcription.
The browser extracts the primary audio track and sends audio chunks for recognition. Leave the page open during preparation and upload. Automatic language detection is the default; choose a language if you already know what is spoken. Transcription continues on the server after upload finishes.

Review, then download.
Use each timestamp to revisit a passage in the audio editor. Correct names, abbreviations and technical terms before copying the result. Download plain text for notes, or use paid subtitle exports for a separate editing workflow. Your original MP4 is not modified.
MP4 checklist
Check the recording before converting
Use this checklist before preparing a long recording. File compatibility and your account duration allowance both matter.
| Recording | What to check | What to do |
|---|---|---|
| Meeting screen recording | Microphone and system sound are audible | Play a passage where participants speak |
| Silent picture track | An audio track exists and contains speech | Export again with microphone audio enabled |
| Multiple audio tracks | The primary track contains the intended dialogue | Export the desired track separately |
| Large recording | The audio index and codec can be read | Keep the browser open during preparation |
Without signing in, start with 10 minutes and 1 file a day. A free account includes 120 minutes per month, up to 30 minutes per file and 3 files a day. See pricing and file allowances for longer recordings.
Audio extraction
Your MP4 picture stays on your device
An MP4 can hold images, sound and other tracks together. Voxcribe reads the sound used for transcription in your browser. The picture track is not sent to the transcription service, and the service does not read slide text or describe what the camera sees.
When a meeting recorder stores microphone audio separately from shared computer sound, the primary track may not contain everything you expect. Voxcribe selects the primary audio track automatically. There is no track picker and no automatic merge of separate tracks. Preview the source and export the intended speech track before uploading if necessary.
A silent recording cannot supply spoken words. Check both the player volume and the recording itself: turning up your speakers cannot restore a microphone that was muted during capture. If speech exists only in another track, prepare an export containing that track. A screen recording with captions but no speech is not a transcription source.

Exports
Take reviewed words back to your video editor
MP4 to text conversion gives you a transcript to check, not a finished captioned movie. Keep the recording and its exported subtitles together so you can compare timing in your editing application.

Sample: synthetic meeting recording (MP4), transcribed by Voxcribe.
Use TXT when you need searchable meeting notes or a passage for an article. Timestamps help you locate the original context before quoting somebody. Remove editing mistakes and check punctuation while listening, especially when the recording includes interruptions or a change of topic.
Paid plans include SRT, VTT, DOCX. Export SRT for timed captions, then import it beside the original MP4 in your video editor. Review the caption timing after trimming or rearranging clips: edits to the movie can move speech away from the timestamps in the original transcript.
Subtitle files are separate downloads. Voxcribe does not burn captions into the MP4 or return a newly rendered movie. If your destination needs text embedded in the image, complete that step in your editor.
Video scenarios
MP4 recordings worth making searchable
The useful output depends on why you recorded the video. A transcript can help you locate an answer or build notes, but it does not replace the visual context or your review of the recording.
Meeting screen recordings
Find the discussion around a decision without replaying every screen share. Check the surrounding conversation before assigning an action to a colleague. Speaker names are not added automatically; identify participants yourself when preparing notes.
Online classes
Search for a term explained in a lesson, then return to the video for the diagram or demonstration. Correct specialist vocabulary in the transcript and keep slide references in your own study notes.
Recorded interviews
Locate an answer by its timestamp and listen to the complete exchange before choosing a quotation. Camera cuts and facial expressions are not captured in the transcript. Add speaker labels manually when needed.
Phone videos
Turn a saved explanation or field recording into a written draft. Wind, traffic and distance from the microphone can obscure words. Choose the clearest original recording and verify uncertain phrases against the sound.
Long recordings
Prepare long MP4 recordings without uploading the picture
The browser reads the source in chunks, which avoids uploading the full video. That helps with large recordings, but it is not a guarantee that every large MP4 will work on every device.
A damaged file, unsupported audio codec or missing audio index can prevent preparation. Very large files that cannot be inspected quickly may be rejected. Try exporting a standard MP4 with an audible track from your recorder, or save the intended audio separately.
Your plan limits the duration that can be transcribed, independently of the video dimensions. Check the available minutes before starting a long session. Uploaded audio is removed after 7 days; transcript retention is 7 days for anonymous use and 30 days for free accounts. Save the text you need. Read the privacy policy for storage details.

FAQ
Questions about MP4 transcription
Check sound tracks, file limits and subtitle downloads before you begin.
Can I convert MP4 to text for free?
Yes. Try a recording up to 10 minutes without an account, with 1 file a day. A free account provides 120 minutes per month and 3 files a day. TXT export is free; subtitle formats require paid access.
What is the MP4 duration limit?
Without an account the per-file allowance is 10 minutes. With a free account it is 30 minutes, subject to the remaining 120-minute monthly allowance. Paid plans have larger allowances. The duration of the speech recording matters, not its picture resolution.
Can I upload a large MP4?
The browser reads the recording in chunks and uploads extracted audio instead of the full picture track. Large MP4 files can work, but unsupported audio codecs, damaged containers or missing indexes can cause preparation to fail. Keep the tab open until upload finishes; device resources and plan duration limits still apply.
Why does my MP4 have no speech in the result?
An MP4 may contain pictures without an audio track, or its microphone track may be silent. Play the source to confirm that speech was recorded. Voxcribe does not read on-screen text. If the microphone was muted during recording, transcription cannot recover the missing speech.
Does Voxcribe transcribe every audio track in an MP4?
No. The browser selects the primary audio track. Voxcribe does not combine all tracks or offer a track selector. If your recording stores participants or languages in separate tracks, export the intended speech track before uploading. Listen to that export to check it contains the conversation you need.
Can I export SRT subtitles from my MP4?
Yes, with paid access. Paid export formats include SRT, VTT, DOCX; TXT is free. Review the transcript, download SRT and import it into your video editor beside the original MP4. The subtitles are a separate file and are not burned into the video.
