A short commerce video needs one clear promise. Choose the source image and primary SKU, then describe subject motion, camera motion, product detail, environment, and final emphasis.
Quick mode is useful when the direction is already clear. Pro mode lets you edit a shot plan, but the final plan still becomes one request to the video model—there is no hidden timeline edit or stitched set of clips.
Default to 9:16 for social commerce. Keep motion plausible and ask the model to preserve product construction, logos, and color throughout the clip.
