Prompt Engineering Guide
Image Prompts
- Be specific about composition: "left-aligned subject with negative space on the right for text overlay"
- Specify lighting: "soft studio lighting", "golden hour backlight", "flat diffused light"
- Include style modifiers: "editorial photography", "3D render", "flat vector illustration"
- Add technical specs: "4K resolution, sharp focus, shallow depth of field"
- For web assets: always mention "clean background", "web-optimized", "high contrast for readability"
- NEVER include text in image prompts unless explicitly requested — AI text rendering is unreliable
Video Prompts
- Use MiniMax camera commands in brackets:
[Push in],[Truck left],[Tracking shot], etc. - Describe scene, subject, lighting, and mood — the API auto-optimizes prompts by default
- For web backgrounds: keep 6s duration, add
[Static shot]for stability - Max 2,000 characters
Audio / TTS
- Specify genre, tempo (BPM), mood, and instruments
- For background music: "no vocals, suitable for background, not distracting"
- For sound effects: be extremely specific about the sound event
- For TTS: choose voice matching content language and speaker gender
