Short-form video creative for paid ads, social, and campaigns produced at the volume that performance marketing requires, dozens of creative variations for A/B testing without the production cost that makes traditional video A/B testing impractical at scale. Model selection matched to content type: Runway Gen-3 Alpha for cinematic scene generation with consistent visual style; Kling for high-motion product action sequences; Pika for short social formats (6-10 second clips) with text overlays; image-to-video via Runway or Kling for animating static product photography into social-ready short clips. Prompt engineering and style guide encoding: your brand's visual language (colour palette, mood, compositional style, product placement rules) translated into generation prompts that produce consistently on-brand output without per-generation prompt crafting by a creative team. Creative variation pipeline: a single brief generates N variations with different visual approaches, text hooks, and lengths (6s, 15s, 30s) for the same campaign, feeding the creative testing framework your performance team runs. Video editing automation using FFmpeg or AWS Elemental MediaConvert: reformatting existing creative into platform-specific aspect ratios (9:16 for Reels and TikTok, 1:1 for feed, 16:9 for YouTube pre-roll), adding platform-compliant text overlays and logo lockups, and trimming to required durations, converting one master creative into every required placement variant automatically. Digital Asset Management integration for storing generated creative with metadata tags and campaign attribution; publishing API connections for direct upload to Meta, TikTok, and YouTube.
