Thumbnails and posters

Design for the Size

Thumbnails are tiny: one bold subject, huge contrast, readable at 120 pixels. Posters are large: layered detail rewards a second look. Match --ar to the platform before generating.

Leave Room for Text

Compose with negative space where titles go; add text in an editor, never in the prompt. Test the thumbnail at actual size before publishing.

Series Branding

Same palette, same layout grammar, varying subjects: viewers should recognize your content before reading a word.
