| Rule | Reason |
|---|---|
| Always add captions | Silent viewing is the default on most platforms |
| Large, readable font | Small text is invisible on mobile |
| High contrast | White text with dark outline/background |
| Centered or bottom-third | Standard viewing position |
| Max 2 lines at a time | More text = can't be read fast enough |
| Key words in bold/color | Draws eye to important words |
# Generate captions from audio
# (create SRT file from your script, then burn in)
infsh app run infsh/caption-videos --input '{
"video": "ad-video.mp4",
"caption_file": "ad-captions.srt"
