How to ai caption generator
- 1
Upload your video
Drag your video file into CentClip or click to browse - no account or sign-up required. Most common formats are accepted, including MP4, MOV, WebM, and AVI. Your first 5 minutes of video are captioned free the moment you upload.
- 2
Confirm your language
CentClip supports 50+ languages and detects the spoken language automatically, but you can set it manually if your video contains a less common dialect or accent. The AI then transcribes the audio and time-stamps every word, so captions stay in sync with the speaker throughout.

Download captions or your captioned video
Choose the output that fits your workflow - download an SRT or VTT file to upload to YouTube, Vimeo, or your LMS, grab a plain text transcript for notes or SEO copy, or get an MP4 with captions burned directly into the picture. All outputs come from the same single upload.
Why choose CentClip?
Captions that stay in sync even with fast speech and crosstalk
Auto-captions from social platforms often drift out of sync on fast dialogue or misfire on overlapping speakers. CentClip's AI timestamps at the word level, so captions track the actual pace of speech rather than applying fixed-length blocks. The result is captions that feel edited even when they are generated automatically - a meaningful difference for anything you are publishing rather than archiving.
All three captioning formats delivered from one upload
Most captioning workflows have at least two destinations: a platform that accepts subtitle files and an offline copy or social clip with captions baked in. Running separate tools for each wastes time and introduces sync errors between versions. CentClip produces burned-in MP4, SRT, VTT, and a plain transcript from a single transcription job, so every format is consistent and ready at once.
Pay per project, not per month
A recurring subscription makes sense if you are captioning video every week - but most teams have bursts: a product launch, a course rollout, an event recap. CentClip charges 5 cents per minute with no seat fee and no idle-month billing. Credits never expire, so you can buy a block before a busy period and draw it down at your own pace without the clock running between projects.
FAQ
How accurate is CentClip's AI Caption Generator?
Accuracy depends on audio clarity, mic quality, and the speaker's accent, but CentClip performs well on typical video content - clear speech in a quiet recording regularly exceeds 95% word accuracy across the 50+ supported languages.
Is there a free trial for the AI Caption Generator?
Yes - your first 5 minutes of video are captioned free with no account required. After that, pricing is 5 cents per minute with no subscription or monthly fee.
What video formats does the AI Caption Generator support?
CentClip accepts most common video and audio formats including MP4, MOV, WebM, AVI, MKV, MP3, WAV, and M4A - so you can caption everything from screen recordings to smartphone footage without converting first.
Do credits expire if I only need captions occasionally?
No - credits never expire. Buy them before a launch, a course release, or any other project-heavy period, and use the balance whenever you need it, whether that is next week or next year.
