Dreamix is a video editing tool utilizing text-driven diffusion models to edit and generate videos. It can modify existing videos based on text prompts, create videos from images by instilling motion, and generate subject-driven videos from a collection of images. The model achieves high fidelity by finetuning on the original video and employs mixed objectives for enhanced motion editability. It supports various applications through preprocessing and a text-guided video diffusion model that upscales the video to the final resolution.
