Understanding WEBM files

What is a WEBM file?

Open web video format for HTML5 and streaming

WEBM is an open, high-quality video standard that is usually used for delivering online videos using the HTML tag. WEBM is a container file format: the video stream is usually compressed with the VP8 codec and the audio stream is compressed with the Ogg Vorbis codec. The WEBM container format itself is based off of the popular Matroska container (MKV files). Since WEBM is an alternative to the patented H.264 and MPEG4 formats and widely supported by most major web browsers, it is used in both commercial and non-commercial applications.
The WEBM file format was created by Google to store video content and implement compression standards optimized for video streaming over broadband and mobile internet connections. Thus, royalty-free video compression technologies were used (VP8/VP9 and Ogg Vorbis). In addition, WebVTT subtitle tracks can we included within a WEBM file. WEBM files are also widely supported by Chrome, Safari, Firefox, and Internet Explorer.

Common Questions

Everything about WEBM to text

Can Sonix transcribe WebM video files?

Yes! Sonix fully supports WebM transcription. Whether your files are YouTube downloads, HTML5 video captures, OBS recordings, or web scrapes, we extract the Vorbis or Opus audio and deliver accurate transcripts.

How well do YouTube downloads in WebM transcribe?

WebM files downloaded from YouTube transcribe excellently. YouTube uses high-quality Opus audio encoding optimized for voice clarity. This makes WebM downloads ideal for transcribing lectures, interviews, and spoken content.

What's the difference between Vorbis and Opus audio in WebM?

Older WebM files use Vorbis audio; newer ones often use Opus. Both transcribe well. Opus is particularly efficient for speech content - it was designed for voice communication and provides excellent clarity even at lower bitrates.

Can I transcribe OBS screen recordings in WebM?

Absolutely! OBS (Open Broadcaster Software) can record in WebM format with excellent quality. Narrated tutorials, game commentary, and screen captures all transcribe well when recorded with clear audio.

How do I create subtitles for WebM videos?

After transcribing your WebM file, export as WebVTT (.vtt) format - the native subtitle format for HTML5 video. You can also export SRT for broader compatibility. Both formats sync perfectly with your video timeline.

Should I convert WebM to MP4 before transcribing?

No conversion needed! Sonix accepts WebM files directly. The Vorbis and Opus audio codecs in WebM provide excellent quality for transcription. Converting to MP4 would just add an unnecessary step.

Sonix is so easy to use, and the quality is impressive in almost all languages we have tested so far. Punctuation is especially amazing compared to other platforms, even the tech giants (Google, Microsoft…).
