Liu Dan waves hello: a real six-second test
Grok · reference_to_video
Before you start
Think of it as a tiny film: Liu Dan is the actor and your AI helper gives Grok the directions. This test used Grok CLI's reference_to_video, not the web buttons. We reuse the saved result, with no new generation bought. Check your account and free allowance before trying again. Stop if payment is needed.

The workflow
- Choose Liu Dan. The real input was a grey-background first frame, her full-body anchor and a face-only reference. The picture here shows the full-body reference, not a generated result.
- Tell an AI helper with Grok access: ‘Use these pictures to make one six-second, 9:16, 720p video. No preset voice.’ Our helper called reference_to_video once. Give it the exact English prompt below too.
- Save the original video. Compare the beginning, middle and end with the reference. Check the face, right hand and camera framing; do not judge only the first frame.
- Keep the limitation: the camera crops the lower body despite the prompt. Use it as a greeting sample and add the required SwimInAI credit. Our preview removes the generated sound.
The same petite adult Chinese woman in the references, with her blunt black bob, straight bangs, same beauty mark, dusty pink T-shirt, dark trousers and white shoes, stands against the warm light-grey studio background. Her right hand moves from beside her hip up to shoulder height and gives two friendly waves, with a small natural smile, as the camera gently pushes in; keep her complete adult body and consistent natural proportions visible throughout. Premium animated 3D feature-film character, visibly CG, not photoreal, soft neutral-white front lighting and clean unbranded clothing.
The actual result
Tested on 2026-10-22
Liu Dan raises her right hand and waves in a six-second clip. Her bob, beauty mark and pink shirt stay recognisable. The camera moves to a medium shot after about two seconds, so this is a greeting sample, not a full-body motion reference. The preview is silent.
Check the result
One successful test is not a promise that every tool or every run keeps the same face. Start with one small action. If the face changes, return to the original reference; do not buy more generations just to follow this page.
Results can look different each time. Check the face, hair, hands and outfit before using one.
