How to auto subtitle generator
- 1
Upload your video
Drag your video file into CentClip - no account or credit card needed for your first 5 minutes. Common formats including MP4, MOV, and MKV are all accepted. Your file is processed in your browser session and is not stored longer than it takes to generate your captions.

Select your language and review captions
Choose from 50-plus supported languages before processing begins, or let CentClip detect the spoken language automatically. Once transcription is complete, a time-synced editor lets you scan every caption line and fix any word the recognizer missed - proper nouns, brand names, and technical terms are the most common corrections. Changes apply in real time before you export.

Download your subtitled video or subtitle files
Export a finished MP4 with captions burned permanently into the picture, or download a standalone SRT or VTT file to pair with your original on YouTube, Vimeo, or any platform that accepts external subtitles. A plain-text transcript is also available from the same screen if you need the words without timecodes.
Why choose CentClip?
Captions that stay locked to the right words - not just close
Auto-generated subtitles are only useful when the timing is accurate enough to follow. CentClip generates word-level timestamps and groups them into readable caption lines that appear and disappear in sync with speech - not drifting ahead or lagging behind by half a second. This matters most on fast-paced social clips, interview edits, and lecture videos where viewers are reading and watching simultaneously. Tight sync is the difference between captions that aid comprehension and captions that cause viewers to give up.
No subscription means you generate subtitles when you have a project, not on a billing cycle
Most auto subtitle tools charge $15 to $30 a month whether you caption one video or twenty. CentClip charges 5 cents per minute - a 10-minute video costs 50 cents, a 30-minute webinar costs $1.50. There is no monthly reset, no tier to upgrade, and no commitment to maintain. Credits never expire, so buying a batch for one project leaves you covered for the next one without any waste.
One upload produces every format your distribution channels require
Platforms have different subtitle requirements. Burning captions into an MP4 is the right move for social feeds that auto-play without sound - captions are visible even when the viewer never touches the volume. SRT files are required for YouTube's closed caption system and searchable transcript indexing. VTT is the standard for HTML5 video players and web-based course platforms. CentClip outputs all three from a single upload so the same video is ready for every channel without re-processing.
