Solution Overview

Problem

Existing methods for generating high-quality transition videos struggle with maintaining semantic consistency, high fidelity, smoothness, and alignment with text prompts, often relying on self-collected datasets and requiring time-consuming training on large-scale motion video datasets.

Innovation Solution

A method using a pre-trained image-to-video diffusion model generates transition frames by creating latent noises based on start and end frames and captions, leveraging latent space representations and de-noising techniques to improve smoothness and reduce randomness without additional training.

Engineering Contradictions & Design Principles
