VideoGen API

When you start a workflow with an AI_IMAGE visual style, the aiStyle field controls how the generated section visuals look. Pass a free-form description of the look you want. A standard style is used when omitted.

Write aiStyle as a full, strict paragraph, the same way the app defaults below are written: name the medium, texture, and palette, then lock composition. A short label such as watercolor or flat art is not enough.

Image models tend to pack the frame with extra objects, readable text, charts, diagrams, tables, and labels. Unless the style forbids that, the still comes out crowded and hard to use. Every description must keep the picture simple: one clear uncluttered subject, centered, occupying only the middle half of the frame, generous empty margins on all four sides, no background clutter, and no on-image text, letters, captions, charts, diagrams, tables, or infographic layout unless you explicitly asked for one specific word or number on screen.

Copy a description below in full. Those already include the uncluttered-subject lock. Add the no-text / no-diagram sentence if you write your own.

Custom styles

Any text you pass is used as the style prompt. Write it at the same length and strictness as the defaults above (medium, texture, palette, then the composition lock). A short label produces crowded frames. For example:

vintage 1970s film photography, warm grain. A clear uncluttered subject centered in the frame, occupying only the middle half of the image, with generous empty margins on all four sides, no background clutter. No on-image text, letters, labels, captions, charts, diagrams, tables, legends, or infographic layout.
