Make-A-Video is Meta AI's latest innovation that takes text as input and generates high-quality, coherent videos. This solution marks a significant advancement in AI by bridging text-to-image generation and extending it to video creation. Let's delve into what it is, how it works, and why it's groundbreaking.
Make-A-Video is a novel AI model developed by Meta AI that enables the generation of short videos from text input. It utilizes a small number of frames to create a coherent and high-quality video, solving difficulties found in previous models that failed at creating realistic and coherent frames over time.
The underlying magic of Make-A-Video lies in adapting a text-to-image model to work with videos. Specifically, Meta AI takes their existing text-to-image model, Make-A-Scene, and includes a spatiotemporal pipeline to handle the complexities of video generation.
Spatial-Temporal Pipeline:
Guidance with Text Input:
To create high-definition videos, Make-A-Video utilizes frame interpolation to generate new and larger frames based on initial low-resolution frames. The interpolation network fills in gaps both in temporal and spatial dimensions, making the movement and overall video fluid and realistic.
Unlike typical methods requiring extensive text-video pairs, Make-A-Video retrains with unlabeled videos. This simplification makes constructing datasets easier and less costly. The model gets accustomed to videos and frame consistency through this retrained process.
