How to transcribe webm
- 1
Upload your WebM file
Drag your .webm file directly into CentClip - no account or credit card needed for your first 5 minutes. CentClip processes WebM natively, so there is no need to convert to MP4 or any other format before you start. The file is processed securely in your browser session and is not stored beyond the duration of your job.

Review your auto-generated captions
CentClip transcribes your WebM audio and presents every caption line with its timestamp in a side-by-side editor. This is the moment to fix anything the recognizer got wrong - product names, technical terms, or words obscured by notification sounds or background audio. Changes are reflected immediately across all export formats before you finalize.

Download your transcript or captioned video
Choose from four output formats: a burned-in video file with hardcoded subtitles, an SRT file, a VTT file, or a plain text transcript. All formats are generated from the same transcription pass, so you only pay once regardless of how many outputs you download. The burned-in video is returned as an MP4, compatible with any platform that accepts standard video.
Why choose CentClip?
WebM files upload directly - no conversion step before you start
Most transcription services reject WebM outright and ask you to re-export as MP4 or MOV first - which is not always possible if the recording came from a browser's built-in capture API or a screen recorder that does not offer format options. CentClip processes WebM natively, so you go from file to transcript without opening a converter. This matters when you have a stack of weekly standups or lecture recordings in .webm format and each extra step multiplies into real lost time. No install, no format juggling - just upload and transcribe.
Browser recordings are often noisy - fix errors before you export
WebM files made with the MediaRecorder API or tools like OBS often have variable audio quality - tab switches, notification sounds, and overlapping voices are common. CentClip gives you a caption-by-caption editor after the transcription pass so you can correct errors before they end up in your SRT file or burned permanently into the video. Three minutes of editing catches the name spellings and technical terms that any recognizer gets wrong on a first pass. You pay for transcription time, not for how long you spend in the editor.
5 cents per minute means three hours of WebM costs $9.00, not a monthly plan
WebM transcription jobs are rarely daily occurrences - it is more likely a semester of lecture recordings, a sprint's worth of user research sessions, or one compliance video that needs subtitles. Paying $20 or $30 a month for a subscription when you have a few hours of footage makes no sense. CentClip charges 5 cents per minute, and credits never expire, so whatever is left after this project will still be there when the next batch of recordings comes in.
