How do I easily add subtitles to my WEBM files? đź“‹

Easily add subtitles to WEBM files in four simple steps:

  1. Upload your WEBM file to Sonix
    Log into Sonix and upload the WEBM file, make sure to select the language that was spoken and then click the “Transcribe” button. If you do not have an account with Sonix, just create one here.

  2. Polish the transcript of your WEBM file
    We use cutting-edge audio transcription to transcribe your WEBM file. Spend a few minutes cleaning up your transcript in our user-friendly transcript editor. You can also translate your transcript to over 30 different languages for an additional charge.

  3. Split your subtitles in the editor
    Powerful subtitle splitting options await you. Set the number of lines per caption, the max number of characters per line, or the max time duration of each caption, and we'll break down your transcript for you. See each caption in our timeline and over the video.

  4. Export subtitles for your WEBM file
    Download SRT and VTT subtitle files of your WEBM file. Then, incorporate them into your video production workflow. Or, if they look good already, you can burn-in the subtitles directly to your WEBM file within Sonix for an additional charge.

That's it! You can download a new WEBM file with the subtitles burned in, or SRT/VTT subtitle files in a matter of minutes. It's a brand new online workflow that makes your life 10x easier.
