|---|---|
| Bold statement | "This tool replaced my entire marketing team" |
| Question | "Why are you still doing this manually?" |

| Social proof | "2 million people switched to this" |
| Pain point | "If you hate [common frustration], watch this" |
Creating Video Ads
Vertical (TikTok, Reels, Stories, Shorts)
# Hook scene (0-3s)
belt app run google/veo-3-1-fast --input '{
"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)
belt app run bytedance/seedance-2-0 --input '{
"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
belt 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
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"
}'
Square (Facebook, LinkedIn Feed)
belt 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
belt 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
belt 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)
belt app run infsh/caption-videos --input '{
"video": "ad-video.mp4",
"caption_file": "ad-captions.srt"
}'
Ad Structure Templates
Testimonial Ad (15-30s)
| Time | Content |
|---|---|
| 0-3s | Customer states the problem they had |
| 3-15s | How they discovered and tried the product |
| 15-25s | The specific result they achieved |
| 25-30s | Product name + CTA |
Demo Ad (15-30s)
| Time | Content |
|---|---|
| 0-3s | The problem (text or visual) |
| 3-20s | Product demo showing the solution |
| 20-25s | Key result/benefit |
| 25-30s | CTA + offer |
Before/After Ad (15s)
| Time | Content |
|---|---|
| 0-3s | "Before" state (messy, slow, frustrating) |
| 3-5s | Transition / product introduction |
| 5-12s | "After" state (clean, fast, satisfying) |
| 12-15s | CTA |
Common Mistakes
| Mistake | Problem | Fix |
|---|---|---|
| No hook in first 1-3s | Viewer scrolls past | Open with pattern interrupt |
| Landscape video on TikTok/Reels | Letterboxed, looks amateur | Use 9:16 for vertical platforms |
| No captions | Most viewers watch silent | Always add captions |
| CTA too late | Viewers already left | Clear CTA within last 5 seconds |
| Too long for platform | Forced skip or dropout | Match platform duration norms |
| Same ad for all platforms | Wrong specs, wrong tone | Create platform-specific versions |
| Logo in first 3s | Feels like a commercial, gets skipped | Save branding for the end |
| Text in unsafe zones | Cut off by platform UI | Check safe zone per platform |
Checklist
- Correct aspect ratio for target platform
- Hook in first 1-3 seconds
- Captions added (readable, high contrast)
- CTA clear and within final 5 seconds
- Duration matches platform norms
- Text outside platform unsafe zones
- Audio designed for both sound-on and sound-off

reddit-automation
flowkit-labs/skills
Find Reddit threads where people are genuinely asking for what you offer, then draft short, genuinely helpful replies — disclosing your affiliation honestly and naming your product only when it truly answers the question. Two moves: discovery — scan the right subreddits for real needs (recommendation asks, expressed pain, competitor mentions) and rank the few threads where you can actually help; drafting — write from real experience, respect each community's self-promo rules, and keep a human in the loop to review and post. This markets on Reddit the honest way: contribute value, disclose who you are, never astroturf. Distilled from the playbook behind doany.ai's Reddit agent. Triggers on "find reddit opportunities", "reddit marketing", "reddit automation", "reply on reddit for my product", "reddit community engagement", "reddit lead gen", or any ask to turn Reddit threads into genuine, disclosed marketing replies.
