# captions-and-subtitles
Caption a video with someone — theirs, of course. Most
short-form video is watched with sound off, and captions are how
deaf and hard-of-hearing viewers get the content at all, so wrong
captions fail real people, and so does shipping without them. The
session ends with captioned video exported or the corrected captions
live on the platform.
## Auto-generate, then fix by hand
Auto-captions are the draft, never the deliverable.
1. Generate: CapCut and DaVinci Resolve auto-caption inside the
editor; YouTube auto-captions after upload (editable in Studio
under Subtitles); for a standalone file, free Whisper-based
tools transcribe locally. Use whichever sits closest to where
the video already is.
2. Fix every line while the video plays. Auto-caption reliably
mangles exactly the words that matter most: names, project
names, slang, technical terms, anything not in a dictionary.
Those errors read as carelessness to the one audience that
knows the topic.
3. Punctuation and casing count — captions are reading material.
Sentence case, real punctuation, no wall of caps.
4. Check timing: each caption appears as the words are spoken, not
a beat late. Split any caption longer than two lines.
5. Keep what was said. Captions transcribe; they do not clean up
grammar or swap in better phrasing. An "um" can go; the meaning
cannot change.
## Styling
- Two lines max, roughly 40 characters per line.
- Big enough to read on a phone h
