Is a WebM file hard to read?
No. WebM is a container: the sound inside it is usually Opus or Vorbis, and that sound is what the engine turns into text.

How to transcribe a WebM file
- 1
Send the file as it is
There is nothing to convert: the container is opened and the audio track inside it is what gets transcribed. The picture never reaches the transcript.
- 2
Name the language and the voices
Rthe recording language is detected automatically. When two people share the recording, switch the speaker split on so every line keeps its name.
- 3
Read the opening minute
Names are what you check first in a transcript. Read the first minute, fix what is off in the app, and save the result to your account.
- 4
Take the text in the shape you need
TXT, Markdown, SRT, VTT and CSV on every plan, DOCX for the editors on Pro. Every exported line keeps the time it starts and ends.

What a WebM file is, and what the transcript holds
| What | Value |
|---|---|
| The container | a profile of Matroska, released in 2010 as a royalty-free alternative for HTML5 video and audio |
| The sound inside | usually Opus or Vorbis; VP8, VP9 and AV1 carry the picture |
| The file | audio and video are both accepted: mp3, wav, m4a, mp4, webm, ogg, flac, aac, wma, mov |
| One upload | up to 30 minutes on the free plan, no minute limit on Pro |
The case
Why the open container is easy to send
WebM came out of the web: it is the container that lets a page play sound and picture without a licence fee. The container is a profile of Matroska, and the sound track inside usually carries Opus or Vorbis. For a transcript the picture is beside the point: what counts is the sound in the box, and that is what the service reads.
Tips
A screen recording of a meeting is usually a WebM.
Check the first minute for names before the export.
Turn the split on when the call has two voices.
Export SRT when the file goes back into a video.
Questions this page answers
What happens to the video part?
It stays in the file and is left alone. Nothing is written back into your WebM, and the picture never becomes part of the transcript.
Where does a WebM file come from?
From a screen recorder, a downloader or a camera that writes the open format. WebM was made for the web, so a page can play it without a licence fee.
How much does the transcription cost?
The free plan is $0 and allows 3 files a day of up to 30 minutes each, without a card. Pro is $10 a month paid yearly, or $20 a month paid monthly.
