Prompt Engineering
Also known as: prompt design, prompting
Definition
Prompt engineering is the practice of crafting input text for AI models to consistently produce desired outputs — covering structure, specificity, style references, negative prompts, and parameter control.
In more detail
For image and video generation: lead with subject, then style references, then lighting/camera, then negative prompts. For long-form video: describe shot list and motion explicitly. Many models reward long prompts (Flux, Sora 2); a few prefer short ones (Stable Diffusion 1.5). Mobbi's tools include built-in prompt enhancers that auto-rewrite minimal prompts into model-tuned ones.

FAQ
Should my prompts be short or long?+
Long prompts (40+ words) work better for Sora 2, Flux Pro, and Nano Banana. Older Stable Diffusion 1.5 prefers comma-separated tags.
