Why settings disappear
Section titled “Why settings disappear”If a control disappears after switching models, the new model does not support that parameter. For example:
- Some models do not support a resolution picker.
- Some models do not support seed or negative prompt.
- Some models support start frames but not end frames.
- Image-to-video-only models require a start frame before rendering.
