A 30-second action montage from key frames on Kling 4

Kling 4 knows what a tail whip, a head spin or a freeze looks like and can string several of them into one 30-second take with its own cuts, camera moves and sound. What it needs from you is the look and the key poses, as stills. The prompt can be one line. This is how the breakdance, scooter and BMX sequences in fal's Kling 4 Halloween film were made (YouTube, 2026-10-30): "really high level prompt, but extremely guided visually".

Generation runs on varg: REST https://api.varg.ai/v2 (the varg-ai skill) or the MCP server https://mcp.varg.ai/mcp.

1. Ask, then go

• Action: breakdance, BMX, skate, scooter, parkour, a chase, a sport. Name 2–3 moves (tail whip, bar spin, ollie, head spin, freeze).
• Place: a real spot with a look (a park arch, bridge banks, a hill with tram rails).
• Ending: a landing, a crash, a reaction line ("Sick run, want to go again?"), or none (a pure loop of moves).
• Frame: 21:9 for a film, 9:16 for Reels and TikTok. Lens: ultra-wide fisheye is the classic sports-video look.
• Cost: 30 s at 1080p ≈ $7.05 (705 credits); 15 s at 720p ≈ $2.36. Expect to keep 5–12 s from a take.

2. Three or four stills

Make them on gpt_image_2_5 with the character and look references ("Image 1 is the rider to match exactly…", see kling-4-prompting section 4). Pick:
