Reference-Image-to-Video Prompt Formula Card: A Visual Guide to Structured Prompting

Set against the backdrop of Vidu Q4 Preview's reference-to-video mode, this piece turns the "structured prompt formula" into a readable motion infographic card. The main subject of the frame is a three-part formula card (subject reference → action and performance → camera and audio), with hand-drawn marks lighting up each formula item one by one, helping developers understand how, under the constraints of up to 15 reference images and 3 reference audio clips, positional references like @Image1 and @Audio1 can be used to write reference assets into a prompt. In terms of composition, this entry uses only a single reference image to carry the card layout and color scheme, while the video portion is genuinely generated by the author's pipeline: following the prompt, the model makes the camera perform a low-amplitude push and local focus around the card, creating the rhythm of "explaining one formula"; 5 seconds long, 720p, 16:9, with native audio enabled for subtle transition sound effects. Use cases: model capability introduction pages, illustrative motion graphics for developer onboarding docs, internal training materials, and short explanatory clips that need to show a team "how reference assets are referenced." As this is a Preview version, actual behavior and availability are subject to the official documentation.
