How to add subtitles to lecture
- 1
Upload your lecture recording
Drag your lecture file onto the CentClip upload area - MP4, MOV, and other common formats are accepted with no account required. Your first 5 minutes are processed free, so short lectures or quick accuracy tests cost nothing. Longer recordings are processed in full before you commit any credits.

Review and correct the auto-generated transcript
CentClip generates a time-coded transcript of everything spoken in your lecture. Click any line to correct a technical term, a proper noun, or a piece of subject-specific vocabulary the model mishears. Corrections update subtitle timing automatically, so you do not need to adjust sync separately.

Export your subtitled lecture in the format you need
Download a burned-in MP4 with subtitles baked into the video, an SRT or VTT file for uploading to YouTube, Vimeo, or your LMS, or a plain text transcript for accessibility documents and study guides. All formats are generated from the same corrected transcript, so one review pass covers every output.
Why choose CentClip?
Per-minute pricing that fits a semester's uneven captioning workload
Lecture recording is not a steady weekly content stream - it clusters around term time and varies wildly in volume. At 5 cents per minute, a 50-minute lecture costs $2.50 and a 10-minute recap clip costs 50 cents, with no subscription accumulating between semesters. Credits never expire, so you can buy a block at the start of term and use whatever remains on the final exam review video months later.
Subtitles that handle the technical vocabulary lectures are full of
Generic transcription tools struggle with the subject-specific terminology, proper nouns, and academic jargon that appear throughout lecture recordings. CentClip's speech model handles this kind of content accurately across 50+ languages, and the editable transcript lets you fix any domain-specific terms before exporting. Accurate subtitles also make lecture recordings searchable for students reviewing material before an exam.
One upload produces every format your institution and students need
A burned-in MP4 works for students watching on any device or platform that does not support external subtitle tracks. An SRT or VTT file can be uploaded directly to Canvas, Moodle, Panopto, YouTube, or Vimeo. The plain text transcript doubles as an accessibility document or a study guide. CentClip produces all three from a single upload, so you caption once and distribute everywhere.
FAQ
How accurate are the subtitles for lecture content with technical terminology?
Accuracy is high for clearly recorded speech, and CentClip handles academic and professional vocabulary well. Clean recordings made with a lapel mic or headset will return fewer errors than recordings picked up by a room microphone in a large lecture hall - but the editable transcript lets you fix any errors before exporting.
How much does it cost to add subtitles to a lecture?
Your first 5 minutes are free with no account required. After that, CentClip charges 5 cents per minute - a 60-minute lecture costs $3.00. There is no subscription, and credits never expire.
What video formats and learning platforms does this work with?
CentClip accepts standard video formats including MP4, MOV, and MKV. The exported SRT and VTT files are compatible with YouTube, Vimeo, Canvas, Moodle, Panopto, Blackboard, and any other platform that accepts external subtitle tracks.
Do my credits expire if I only caption lectures a few times a year?
No - CentClip credits never expire. Buy a block when you need it and use the remaining balance on your next lecture recording, whether that is next week or next semester.
