Video Creative Specs

| Format | Length | Skip | Best For | |--------|--------|------|----------| | Skippable in-stream | 15s-3min (recommend 30-60s) | After 5s | Lead gen, conversions | | Non-skippable in-stream | Max 15s | No | Brand awareness, key messages | | Bumper | Max 6s | No | Retargeting, frequency |

Video Production Checklist (for AI agent)

The agent does NOT produce video. The agent prepares a creative brief for each variant:

1. Hook (first 5 seconds): This is the ONLY part most viewers see. Must contain the pain point or a surprising stat. Structure: "[Stat or question] — here's what you can do about it."
2. Body (5-25 seconds): Describe the solution approach (NOT your product). Educate. Show credibility.
3. CTA (last 5 seconds): Clear action. "Download the free checklist." "Watch the full breakdown." Never "Sign up for a demo" at problem-aware stage.
4. On-screen text: Repeat the headline and CTA as text overlay for sound-off viewers (53% of YouTube is watched on mobile, many without sound).

Variant Framework for Testing

For each pain point, create 3 video ad variants:

• Stat Hook: "83% of data teams spend 20+ hours a week on pipeline maintenance. Here's why."
• Question Hook: "Is your data team stuck maintaining pipelines instead of building models?"
• Proof Hook: "How [Company] cut data pipeline failures by 90% in 30 days."

Error Handling

• VIDEO_NOT_FOUND: YouTube video ID is invalid or video is Private. Must be Public or Unlisted.
• VIDEO_TOO_LONG: Bumper ads must be <=6s, non-skippable must be <=15s.
• IMAGE_ERROR: Companion banner must be 300x60px PNG or JPG, under 150KB.
• FINAL_URL_DOES_NOT_MATCH_DISPLAY_URL: Ensure final URL domain matches the display URL domain.
