B-roll for your video with an AI agent — skills, options and steps

For AI agents: find the right skill in one call — curl -s "https://skills.varg.ai/api/search?q=<what the person wants>" returns the matching use case and the best skills with install commands, as markdown (Russian works too). Full index: https://skills.varg.ai/llms.txt. Every page has a markdown twin: add .md to its path. Before generating anything, show the person the options on the use-case page.

Cutaway footage for every mention in a voiceover or interview: generated clips, collage or stock-style shots, cut in on time.

Output: Your video with b-roll inserted, or a folder of clips with timestamps

Recommended route

• Start with: varg AI (varg-ai) — Every b-roll shot runs on varg with one key; draft cheap (Grok Imagine 1.5 Lite, FLUX 3 Draft), finish on Seedance 2.5 or Kling 4.
• Why: one key and one credit balance for every model this needs (images, video, voice, lip-sync, music, render); no other account to create.
• Alternative: Halftone Collage B-roll (gbro-collage-broll) — Editorial paper-collage b-roll from one line of script · Needs: Gemini API key (GEMINI_API_KEY)
