A new era of AI content creation has begun.
Nvidia just announced its text-to-video model.
Here's how it's going to transform the future of video forever:
1/ Nvidia releases Video Latent Diffusion Models
Let's start with the basics.
A Latent Diffusion Model (LDM) is a way of creating realistic images or videos using AI.
It learns patterns from other images without needing a super-powerful computer.
2/ Text-to-video synthesis with Stable Diffusion
Nvidia leverages Stable Diffusion for text-to-video generation:
β€’ Resolution up to 1280 x 2048
β€’ 4.7-second-long clips at 24 fps
β€’ 4.1B parameters
Nvidia adds a time-related aspect to the model to turn it from image β†’ video.
3/ Pre-training and fine-tuning of Video LDMs
Nvidia's approach involves:
β€’ Pre-training an LDM on images
β€’ Introducing a time (temporal) dimension for video generation
β€’ Fine-tuning image sequences
This enables smoother integration of pre-existing image LDMs into video.
4/ Real-world applications
Nvidia has validated Video LDMs for:
β€’ In-the-wild driving scene video generation
β€’ Creative content creation with text-to-video modelling
One thing is for sureβ€”hyperrealism is getting scarily good.
Imagine the movies and video games that will be created over the next 5 years.
The train is leaving the station.
