description="Convert an image into a trajectory-following video. Images are automatically resized down to a max edge of 512. | NOTE: The current runtime for a sample is around 400-700 seconds. Running on a lower number of frames could help! Do be patient as this is on CPU-only, BUT if this space maybe gets a GPU one day, it's already configured to run with GPU-support :) If you have a GPU, feel free to use the author's original repo (linked at the bottom of this path, they have a collab notebook!) You can also run this space/gradio app locally!"
