  "prompt": "vertical video, smooth product reveal, clean wireless charging station on minimalist desk, satisfying organization transformation, bright modern room, social media ad aesthetic",
  "ratio": "9:16",
  "generate_audio": true
}'

# Add voiceover

  "prompt": "[S1] Stop wasting time with this mess. This one product changed my entire setup. Everything charges. Everything is organized. Link in bio."
}'

# Merge video + audio
belt app run infsh/video-audio-merger --input '{
  "video": "solution-reveal.mp4",
  "audio": "voiceover.mp3"
}'

# Add captions (critical for silent autoplay)
belt app run infsh/caption-videos --input '{
  "video": "ad-with-audio.mp4",
  "caption_file": "captions.srt"
}'

  "prompt": "square 1:1 video, professional person at desk discovering a new software tool, laptop screen showing clean dashboard, natural office lighting, corporate commercial style, satisfied expression"
}'

}'

# Keep it tight

  "prompt": "[S1] Your reports. Automated. Try DataFlow free."
}'

Captions Are Mandatory

85% of Facebook and 40%+ of Instagram video is watched on mute.

Caption Best Practices

RuleReason
Always add captionsSilent viewing is the default on most platforms
Large, readable fontSmall text is invisible on mobile
High contrastWhite text with dark outline/background
Centered or bottom-thirdStandard viewing position
Max 2 lines at a timeMore text = can't be read fast enough
Key words in bold/colorDraws eye to important words
# Generate captions from audio
# (create SRT file from your script, then burn in)
belt app run infsh/caption-videos --input '{
  "video": "ad-video.mp4",
  "caption_file": "ad-captions.srt"
}'
