How to add captions to online course
- 1
Upload a course module video
Drag your lesson file onto the CentClip upload area - MP4, MOV, and other common formats are accepted. No account is required, and your first 5 minutes are processed free. You can work through modules one at a time or return whenever your production schedule allows.
- 2
Review the transcript and fix course-specific terms
CentClip generates a time-coded transcript you can scan before exporting. Click any line to correct a product name, instructor name, or subject-specific term your course uses repeatedly. Edits apply to the captions and the export in one step - no separate timing adjustments needed.

Export captions or a captioned video
Download an SRT or VTT file to attach to your video on Teachable, Thinkific, or YouTube, or export a burned-in MP4 for platforms that do not support separate caption tracks. A plain text transcript is also available if you want to include searchable lesson notes alongside the video.
Why choose CentClip?
Per-minute pricing fits how course production actually works
Most course creators record in batches - shooting five modules in a weekend, then nothing for six weeks. A subscription charges you through every quiet period whether you caption anything or not. At 5 cents per minute, a 10-module course with 20-minute lessons costs exactly $10 to caption, and unused credits carry forward indefinitely. There is no deadline pressure to use up a monthly allotment before it resets.
Caption files that drop straight into your course platform
Teachable, Thinkific, Kajabi, and most other course platforms accept SRT or VTT caption files uploaded alongside the video - no special encoding or re-export required. CentClip produces both formats from the same transcript review, so you can meet the technical requirements of whichever platform you use without processing the video a second time. Burned-in MP4 is also available for platforms or players that do not support sidecar caption files.
Caption courses in 50+ languages without a translation step
If you record in Spanish, French, Portuguese, German, or any of 50+ supported languages, CentClip transcribes directly in that language - it does not translate from English. This matters for educators selling to audiences in markets where courses are recorded in the learner's native language. Accurate same-language captions improve comprehension and course completion rates without adding a separate localization step to your workflow.
FAQ
How accurate are captions on a typical online course video?
Accuracy is high for clear recordings made with a headset or lapel mic. The built-in transcript editor lets you catch and fix any errors - especially repeated terms like product names or technical vocabulary - before you export.
Is there a free trial, and how much does captioning cost after that?
Your first 5 minutes are free with no account required. After that, captioning costs 5 cents per minute with no subscription - a 30-minute lesson is $1.50, and you only pay when you actually caption something.
Which course platforms and output formats does CentClip support?
CentClip exports SRT, VTT, burned-in MP4, and plain text transcripts. SRT and VTT files work with Teachable, Thinkific, Kajabi, Udemy, YouTube, and most other platforms that accept caption uploads.
Do my captioning credits expire if I finish a course and don't need them for a while?
Credits never expire. You can buy a block at the start of a production run and use the remainder months later when you record your next course - there is no renewal deadline or minimum usage requirement.
