Workflow Tips for Ad Production

1. Start with Concept Testing

Generate 5-10 variations with different prompts. Use Luma for speed, then refine winners with Kling or Seedance.

2. Batch by Aspect Ratio

Group ads by platform: 16:9 for YouTube pre-roll, 9:16 for Stories, 1:1 for feed ads.

3. Use Multi-Shot for Narratives

Tools like Kling 4.0 and Seedance 2.0 let you connect 3-5 clips into one story—perfect for 15-30 second ads.

4. Add Audio Last

Generate video first, then layer music and voiceover. Native audio tools (Kling, Pika, Seedance) save time but limit control.

5. Test Platform-Specific Formats

What works on YouTube may fail on TikTok. Generate platform-specific versions:

  • YouTube: 16:9, 15-30 seconds, slower pacing
  • Instagram Reels: 9:16, 7-15 seconds, fast cuts
  • Facebook Feed: 1:1, 6-10 seconds, text overlays

Common Mistakes to Avoid

Over-prompting: Long prompts confuse AI models. Keep it under 20 words.

Ignoring aspect ratios: Generate in the target format—don't crop 16:9 to 9:16.

Skipping iterations: First output is rarely perfect. Generate 3-5 variations.

Forgetting brand guidelines: AI won't match your brand colors automatically—add them to prompts.
