How to auto captions
- 1
Upload your video
Drag any video file into CentClip - MP4, MOV, WebM, MKV, and other common formats are accepted. No account or credit card is needed for your first 5 minutes, so you can test the transcription accuracy on your actual footage before committing to anything. The file is processed and captions appear in the editor shortly after the upload completes.

Review and edit the caption track
CentClip generates a complete time-synced caption track automatically and displays each segment in an editor alongside its start and end times. Scan through the results and correct any misspellings, names, or technical terms the recognizer did not catch - most short videos need only a minute or two of light editing. The transcript you approve is what ends up in the final file.

Download in the format that fits your platform
Export a burned-in MP4 with captions locked into every frame, ready to post on any platform as-is. You can also download an SRT or VTT subtitle file to upload as a separate caption track on YouTube, Vimeo, or any learning management system. A plain text transcript without timecodes is included if you need the words alone for show notes, a blog post, or a searchable document.
Why choose CentClip?
Auto-synced timing cuts captioning from hours to minutes
Typing out words is the easy part of manual captioning - synchronizing each line to the exact second it is spoken is what takes hours. CentClip's speech recognition generates timecoded caption blocks automatically, leaving you with a review pass rather than a full transcription session. On a 15-minute video, the difference is typically 2-3 hours of manual sync work versus a 5-10 minute edit. That gap matters most when you have a backlog of recordings or a same-day publishing deadline.
One workflow for every spoken language in your library
If you produce content in more than one language, managing separate tools for each adds friction and introduces errors - especially when correcting words in a language you don't read fluently. CentClip's auto captions handle speech in 50+ languages using the same upload-review-export flow regardless of which language is spoken. Switch the language setting at upload and the rest of the process is identical. There is no extra cost or separate plan for non-English content.
A plain transcript turns every video into a reusable text asset
Every auto-caption job in CentClip also produces a plain text transcript you can use beyond the video itself. Copy it into a blog post, paste it as podcast show notes, turn it into a LinkedIn article, or feed it into a search index - the spoken words become a text asset at the same time captions are generated. For educators or podcasters with large back-catalogs, that transcript output adds lasting value to each recording well after the initial publish date.
FAQ
How accurate are CentClip's auto captions?
CentClip produces accurate captions from clear speech and performs best with direct-to-camera or voice-over audio with minimal background noise. Every caption segment is editable in the reviewer before export, so you can correct proper nouns, technical terms, or anything the model missed before downloading.
Are the first 5 minutes of auto captions really free?
Yes - your first 5 minutes are completely free with no account and no credit card required. After that, auto captions cost 5 cents per minute with no subscription and no minimum purchase.
What file formats does the auto captions tool accept?
CentClip accepts common video and audio formats including MP4, MOV, MKV, WebM, MP3, and WAV. Output options are a burned-in MP4, an SRT file, a VTT file, or a plain text transcript - all compatible with YouTube, TikTok, Vimeo, and any platform that supports standard subtitle formats.
Do auto caption credits expire if I don't use them right away?
No - CentClip credits never expire. Buy them for one project and use whatever remains on any future video, with no monthly reset or deadline to spend them.
