• Engagement — Videos with subtitles see 40% more views and 80% more watch time according to social media studies.

Subtitle Best Practices

• Keep it readable — Max 2 lines per subtitle, max 42 characters per line
• Timing — Display each subtitle for at least 1.5 seconds, sync with speech
• Font choice — Use sans-serif fonts (Arial, Helvetica) for screen readability
• Contrast — White text with dark background/shadow works on any video
• Position — Bottom-center is standard; move up if it obscures important visuals
• Burn in for social — Since most social videos auto-play muted, burn subtitles into the video file itself
