How to closed caption generator
- 1
Upload your video
Drag your video file into CentClip - no account or credit card required for your first 5 minutes. CentClip accepts the most common video formats including MP4, MOV, MKV, AVI, and M4V. The upload runs in your browser, so your file is not stored longer than it takes to process.

Review and correct your captions
Once your video is transcribed, a time-synced editor displays every caption line alongside its start and end timestamp. Scan through and fix any words the recognizer missed - proper names, brand terms, and technical vocabulary are the most common spots to review. Corrections take effect immediately before you generate the final output.

Export your captioned video or subtitle files
Choose to burn the captions permanently into a new MP4, or download a standalone SRT or VTT file to pair with your original on YouTube, Vimeo, or any compatible platform. A plain text transcript is also available from the same screen if you need the words without timecodes.
Why choose CentClip?
Pay per video, not per month, when your captioning needs are irregular
Most teams that need closed captions do not caption videos every single week - they have a course launch, a compliance deadline, or a product demo batch, and then nothing for two months. Subscribing at $15-30 a month to cover those sporadic bursts means paying for idle time. CentClip charges 5 cents per minute with no subscription, so a 20-minute training video costs exactly $1.00 - and the credits you buy for this project never expire, so leftovers carry forward to the next one.
The caption editor lets you fix what matters before you export
Closed captions that contain errors undermine the accessibility they are supposed to provide - a misheard name or a garbled product term can confuse viewers and fail compliance checks. CentClip's time-synced editor shows every line next to its exact timestamp, making it fast to catch and correct mistakes before the file leaves your browser. You are not locked into the raw AI transcript: the exported MP4, SRT, or VTT reflects your edits, not the first-pass output.
One upload, every output format you might need
Closed captions need to work in different contexts depending on where the video lives: burned into the picture for social platforms, attached as an SRT for YouTube's caption system, uploaded as a VTT file for a video host, or pulled as plain text for a transcript page. CentClip produces all four from the same transcription pass - no re-uploading, no re-processing, and no additional charge to switch formats.
FAQ
How accurate is CentClip's Closed Caption Generator?
Accuracy depends primarily on audio quality - clear speech with minimal background noise gives the best results. A built-in editor lets you review and fix every caption line before you export, so the finished file reflects your corrections rather than the raw transcription.

Yes - CentClip gives you 5 free minutes with no account and no credit card required. After the free tier, captioning costs 5 cents per minute with no subscription and no minimum purchase.
What video formats does the Closed Caption Generator accept, and what can I export?

Do CentClip credits expire if I don't use them right away?
No - CentClip credits never expire. Buy a block for this project and use whatever is left months later with no monthly reset or subscription deadline.
