How to ai subtitle generator
- 1
Upload your video or audio file
Drop your file into CentClip or paste a link - no account or credit card needed for your first 5 minutes. The tool accepts common formats including MP4, MOV, WebM, and MP3. Processing starts immediately after upload, so you are usually looking at a transcript within a minute or two of dropping your file.

Review the AI-generated subtitles
CentClip's AI transcribes the spoken content, splits it into readable subtitle segments, and syncs each line to the correct timestamp automatically. The editor shows every line so you can scan for any words the model got wrong - brand names, acronyms, and proper nouns are the most common places to check. Edits save in real time and carry through to every export format.

Download your subtitled video or subtitle files
Choose burned-in captions to receive an MP4 with subtitles rendered into the picture, or download an SRT or VTT file to attach the subtitles separately on YouTube, Vimeo, or your own player. A plain text transcript is also available if you need the words without timecodes. All export formats are generated from the same transcription run - no reprocessing required.
Why choose CentClip?
AI handles the timing so you never have to place a subtitle cue by hand
The hardest part of generating subtitles manually is not writing the text - it is lining each cue up to the right millisecond. CentClip's AI transcribes the audio and assigns timestamps automatically, producing a properly timed subtitle file from the first pass. For a 20-minute video, that eliminates what could otherwise be an hour or more of frame-stepping and cue-dragging in a dedicated subtitle editor. You arrive at the review step with the timing already done.
No subscription means you are not paying for months you do not subtitle anything
Most AI subtitle tools charge a monthly fee regardless of how often you use them. CentClip charges 5 cents per minute and nothing else - a 10-minute video costs 50 cents, and you only spend money when you actually have a video to subtitle. Your first 5 minutes are free with no account required, so you can check the accuracy on real content before buying credits. Credits never expire, so whatever you load up today is still there the next time a project comes in.
One upload produces every subtitle format the video will need
A finished video often needs to go to multiple destinations - a burned-in MP4 for social, an SRT for YouTube, a VTT for a web player or LMS. Running three separate tools or reprocessing the same file to hit each format adds time and introduces inconsistency. CentClip generates burned-in MP4, SRT, VTT, and plain transcript from a single transcription run, so you choose the format at download time rather than at upload time.
FAQ
How accurate is CentClip's AI subtitle generation?
Accuracy is highest on clear speech with minimal background noise - under those conditions the AI typically requires only light edits for brand names or uncommon proper nouns. The built-in editor lets you review every subtitle line and correct errors before downloading the final file.
Is there a free plan, and what does it cost after that?
Your first 5 minutes are free with no account or credit card required. After that, CentClip charges 5 cents per minute with no subscription, no monthly minimum, and no expiring credits.
What file formats can I upload, and what subtitle formats can I export?
CentClip accepts video and audio files including MP4, MOV, WebM, MP3, and WAV. Exports include a burned-in MP4, SRT, VTT, and plain text transcript - all compatible with YouTube, Vimeo, and most web video players.
Do my CentClip credits expire if I don't use them right away?
No - CentClip credits never expire. Buy them for a current project and use whatever is left whenever your next video comes in, with no time pressure.
