Before / After Transformation Video Prompt for HunyuanVideo
This is the HunyuanVideo version of the before / after transformation video prompt: one locked-off shot that carries a subject from its before state to its after state — the change is the whole clip. It is formatted the way HunyuanVideo takes prompts best. Free — copy it, replace the bracketed parts, and paste it in.
The prompt
Push copies this prompt with a reference line naming your image, and downloads the image file — attach it in the model to complete the pair. This page stages the pair for you; it cannot upload into the model itself (sites cannot reach into each other), so the final attach happens there. The image is downscaled to at most 1024px and stored only in this browser, paired with this prompt. If browser storage is full, it is kept for this visit only.
The deliverable — and how to check it
Deliverable: one 10-second clip from a single locked-off camera position: the before state holds for the first 3 seconds, the transformation plays through the middle, the after state holds for the final 3 seconds, angle and framing identical throughout. Acceptance check: overlay the first and last frames — the frame edges must align exactly; any cut, reframing or light-direction change fails the clip.

Using this prompt with HunyuanVideo
HunyuanVideo (Tencent, current 1.5 line) is an open-weights video model that rewards detailed descriptive prose — the longer and more complete the shot description, the better it follows. It does both text-to-video and image-to-video, so a keyframe can anchor the shot. It generates no native audio (Tencent pairs it with a separate sound model) — plan the soundtrack separately. At 8.3B parameters it runs on consumer-grade GPUs locally, unusually light for its quality class.
What this route costs — and how to pay less
Cost structure: open weights — HunyuanVideo runs on your own hardware (consumer-grade GPUs suffice for the 1.5 line), so the marginal cost per generation is zero. The same prompt is pre-configured in this library for every major model, so you can run it on whichever route fits your budget — comparing the structures before you generate is a free way to save money.
Replace the bracketed placeholders — [SUBJECT], [BEFORE DESCRIPTION], [AFTER DESCRIPTION] — with your own details before pasting.
