Creating Video Ads
Vertical (TikTok, Reels, Stories, Shorts)
# Hook scene (0-3s)

"prompt": "vertical 9:16 video, close-up of hands struggling with tangled cables and messy desk, frustrated energy, shaky handheld camera, authentic social media style, bright lighting"
}'
# Solution reveal (3-15s)
infsh app run bytedance/seedance-1-5-pro --input '{
"prompt": "vertical video, smooth product reveal, clean wireless charging station on minimalist desk, satisfying organization transformation, bright modern room, social media ad aesthetic"
}'
# Add voiceover
infsh app run falai/dia-tts --input '{
"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
infsh app run infsh/video-audio-merger --input '{
"video": "solution-reveal.mp4",
"audio": "voiceover.mp3"
}'
# Add captions (critical for silent autoplay)
infsh app run infsh/caption-videos --input '{
"video": "ad-with-audio.mp4",
"caption_file": "captions.srt"
}'
Square (Facebook, LinkedIn Feed)
infsh app run google/veo-3-1-fast --input '{
"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"
}'
YouTube Bumper (6 Seconds)
# 6-second bumper: one message, one visual, one CTA
infsh app run google/veo-3-1-fast --input '{
"prompt": "6 second product ad, quick montage of a sleek app being used on phone, fast cuts, modern, energetic, brand logo reveal at end, punchy and dynamic, wide 16:9"
}'
# Keep it tight
infsh app run falai/dia-tts --input '{
"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
| 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"
}'
