FAQ
Online course subtitle FAQs
Can I process an entire course at once?
No. The current product processes one uploaded video at a time, so caption each lesson separately.
Does it handle technical/coding content?
Technical terms, code words, and formulas spoken aloud can be transcribed incorrectly in the first draft. Review and correct them in the editor before export.
What LMS platforms are compatible?
The export is an MP4 with the captions burned in. Separate SRT or VTT files are not available from the editor yet; the standalone converters under /tools work on subtitle files you already have. You can upload the captioned MP4 to a course platform like any other video; there is no LMS integration.
Does it meet accessibility requirements?
CapsAI does not certify compliance with accessibility standards. Review and correct the captions, then check them against the requirements your platform or institution follows.
Can I translate my course into other languages?
No. CapsAI generates captions in the spoken language you select; it does not translate captions into another language.
Which files can I upload?
The uploader accepts MP4 or MOV video files. Audio-only files and pasted video URLs are not part of the caption workflow.
Can I download SRT or VTT subtitle files?
The export is an MP4 with the captions burned in. Separate SRT or VTT files are not available from the editor yet; the standalone converters under /tools work on subtitle files you already have.
How accurate are the captions?
Accuracy depends on audio clarity, background noise, accents, and language selection. CapsAI creates a first draft and lets you edit captions before export.
How much can I try for free?
You can start with 3 free minutes. Free video export may include a CapsAI watermark; watermark-free video export is listed as a paid-plan benefit.
