# Between Frames

A Hugging Face Space for generating a video from:

- a required start image;
- an optional end image; and
- a text prompt describing the action, subject motion, and camera movement;
- a selectable duration of 1, 2, or 3 seconds.

The app uses [`Wan-AI/Wan2.1-FLF2V-14B-720P-diffusers`](https://huggingface.co/Wan-AI/Wan2.1-FLF2V-14B-720P-diffusers). When no end image is supplied, the same pipeline runs in regular image-to-video mode.

## Deploy

1. Create a new **Gradio** Space on Hugging Face.
2. Upload the files in this repository.
3. Select **ZeroGPU** in **Settings → Hardware**.
4. Wait for the model weights to download on the first build/request.

The model is large. CPU-only hardware is not supported. The app requests ZeroGPU's 96 GB `xlarge` tier while a generation is running and dynamically scales the reservation with the selected duration, resolution, and step count. Usage remains subject to Hugging Face's daily ZeroGPU quota and queue.
