| ### Quick Start | |
| 1. Provide `Prompt` and `Negative Prompt` for each model. You are encouraged to refer to each model's webpage on CivitAI to learn how to write prompts for them. Below are the DreamBooth models in this demo. Click to visit their homepage. | |
| - [`toonyou_beta3.safetensors`](https://civitai.com/models/30240?modelVersionId=78775) | |
| - [`epiCRealismNatural.safetensors`](https://civitai.com/models/25694/epicrealism) | |
| 2. Select 'Length' to set the length of the generated video. | |
| (When you are working with ComfyUI try all possible length, with different motion_scale) | |
| 3. Click `Generate`, wait for ~2 min, and enjoy. | |
| 4. In order to effectively utilize 'lt_long_mm_16_64_frames' model, it is highly recommended to use the ComfyUI interface, which enables to easily increase 'motion_scale'. | |
