Product demo b-roll

The prompt

Slow-motion b-roll of {{product}} in use, macro close-up, soft studio lighting, 120fps, cinematic color grade.

Expected result

Smooth slow-motion macro footage of the product in use, evenly lit, suitable for cutting into a longer edit as B-roll.

Why it works

Specifying frame rate is what actually triggers slow-motion-appropriate footage — without it the model may render at a rate that looks choppy when slowed down later.
