FLUX 3 Edit is one of 29 video models Hermoso can render a video ad, product sizzle or UGC clip with. Name it, or leave the model out and the router picks a sound default. The same catalog is available from the app, the MCP server and the CLI, on one account and one credit balance; the exact price of every render is shown in the app before it runs.

What people make with it

  • UGC testimonials and talking creators
  • Product sizzles and packshot spins
  • Cinematic brand films
  • Faceless product demos and explainers

  • 1:1 for Feed posts and carousels
  • 4:3 for Presentations and display

Getting the best out of FLUX 3 Edit

  • Describe one continuous camera move and where it ends. The model renders motion, not a shot list.
  • Attach the real product photo as a reference and ask for it matched exactly. Never describe a lookalike.
  • Name colours in words. A hex code turns into text on screen.
  • Keep spoken lines short. Roughly two words per second is what a clip can carry cleanly.
  • Ask for the placement's ratio up front (9:16 for Reels and TikTok) instead of cropping afterwards.
