Do I have to extract the audio first?

No. Upload the MP4 as is; doing it manually only adds time and can reduce quality.

What if the MP4 has no audio track?

We'll let you know: there's nothing to transcribe.

Does the video resolution matter?

No. We only process the audio, regardless of whether the video is 4K or 480p.

Can I get an SRT file?

Yes, from the same transcript, with the timings already synchronised with the video.

Do I have to convert the MP4 first?

No. Upload the file as is; we process the internal audio track automatically. Converting first only makes sense if your connection is slow and you'd rather upload less data.

What if the video has no audio?

We'll let you know as soon as we check, with no minutes deducted from your quota. This usually happens with screen recordings where the microphone was disabled.

About this tool

An MP4 file contains a video track and an audio track. Transcribing it consists of processing the second one, which happens automatically when you upload the file.

It's the format generated by mobile phones, screen-recording apps and video calls, which makes it the most common format among those who need to transcribe content. We support any internal audio codec: AAC, MP3, or whatever your device uses.

Features

Compatible with any internal audio codec: AAC, MP3, ALAC and PCM.
Timestamps are synchronised with the video.
Voice identification, key to making a recorded call legible.
No prior conversions or software to install.

How it works

DOCX or PDF for reading; SRT or VTT for subtitles, with the timings already calculated.

Use cases

Zoom and Teams recordings

Both platforms export as MP4. Upload directly to get the minutes.

Video recorded on a phone

A talk, class or interview filmed on your phone, ready to transcribe.

Screen recordings

Turn a demo or tutorial into a written, editable script.

In detail

The MP4 files from Zoom, Meet and Teams

Recording a video call on any of these three platforms produces an MP4 file, which tends to give good results: each participant speaks through their own microphone, there's little ambient noise, and voices overlap less than in an in-person meeting. If the recording keeps separate tracks, speaker identification is especially accurate.

The only notable factor is size: an hour of high-definition meeting can take up two to three gigabytes, weight that corresponds entirely to the picture. You can upload the full file within the 50 GB limit, or extract the audio first and reduce it to about 50 MB.

Video recorded with a phone

Works just as well, and is more common than it might seem: interviews recorded on a phone, statements, entire lectures. Orientation or resolution don't affect the result, since the picture isn't part of the process; what matters is microphone placement.

One piece of advice matters more than any setting here: when recording a conversation with your phone, place it near whoever is speaking rather than in the centre of the table. That difference affects the final result more than any configuration available.
