Use reference images, videos and audio to direct a new scene. The inputs guide different things: images establish appearance, video guides movement, and audio guides voice or sound. Refer to them in upload order as @Image1, @Video1 and @Audio1. You can combine up to fifteen files, within each input type’s limit.

References are numbered by type in the order you upload them. The second picture you add becomes @Image2, the first clip is @Video1 and the first sound file is @Audio1. Writing those names in the prompt tells the model what each file is for, for example: “the adult woman from @Image1 moves like the dancer in @Video1 and speaks in the tone of @Audio1”.
Without names, the model has to guess which file controls appearance and which controls motion or sound. If you remove or reorder uploads, read the prompt again, because the numbers follow the current upload order. One clear job per reference usually works better than several files that all describe the same thing.
Keep original sound is off by default, so the new clip gets freshly generated synchronized audio. When you have uploaded a reference video, you can switch it on to carry that soundtrack into the result; the option needs at least one video. Aspect ratio defaults to auto, or you can fix it at 16:9, 9:16, 1:1 or 21:9. Output is 720p or 1080p and 3 to 30 seconds long.
GenSpicy asks for at least one reference before you can submit. The Peppers quote reflects duration, resolution and any reference videos, so a task that leans on several clips can cost more than one guided by images alone. Check the number after your last upload: that is the amount reserved on submission and released if the task is confirmed as failed or timed out.
