Captions and subtitles are generated directly from the video's audio track on hardware we own — the video itself never has to go anywhere public to get captioned.
The problem with the obvious shortcut
The easiest way to auto-caption a video is usually to upload it somewhere public like YouTube and pull the generated captions back down. For internal training material, onboarding videos, or anything under an NDA, that's not actually an option.
How it works instead
The video's audio track is transcribed and turned into a standard subtitle file, returned alongside the original video, without the footage ever needing to be hosted anywhere public.
Where this breaks down — said plainly
- Caption accuracy depends on audio quality, same as any transcription step — background noise and overlapping speech raise the error rate.
- Burned-in captions (rendered into the video itself) are a separate ask from a standard subtitle file — say which one you need.
