Prompting Guide for Video Generation

Crafting effective prompts to leverage the full potential of Layer's video generation.

Updated over 2 months ago

Crafting effective prompts for video generation is key for creating high-quality assets you can use in your game. We currently support generations with Hunyuan, Kling 1.5 Pro, Minimax, and Minimax Live - and more models on the way. Below, we outline best practices for writing prompts tailored to these models, ensuring you achieve high-quality, consistent outputs.

General Tips for Writing Prompts

  1. Be Specific: Include clear details about the scene, subject, style, and any desired camera movements.

  2. Structure Your Prompt: Follow a logical sequence to include:

    • Main Subject

    • Background/Environment

    • Style (e.g., cinematic, realistic, cartoon)

    • Shot Type (e.g., close-up, wide-angle)

    • Camera Movement (e.g., pan left, tilt down)

    • Atmosphere or Mood (e.g., tense, cozy)

  3. Use Action Verbs: Describe dynamic scenes using words like “running,” “zooming,” “tilting,” to guide the model.

  4. Incorporate Metadata: When available, use tags like “high-definition” or “360-degree” to add precision.
