Kandinsky Video is a text-to-video generation model, which is based on the FusionFrames architecture and Kandinsky 3.0 text-to-image model, consisting of two main stages: keyframe generation and interpolation. Our approach for temporal conditioning allows us to generate videos with high-quality appearance, smoothness and dynamics.

Pipeline

The encoded text prompt enters the U-Net keyframe generation model with temporal layers or blocks, and then the sampled latent keyframes are sent to the latent interpolation model in such a way as to predict three interpolation frames between two keyframes. A temporal MoVQ-GAN decoder is used to get the final video result.

Architecture details

• Text encoder (Flan-UL2) - 8.6B
• Latent Diffusion U-Net3D - 4.0B
• MoVQ encoder/decoder - 256M

How to use

1. text2video

from video_kandinsky3 import get_T2V_pipeline

t2v_pipe = get_T2V_pipeline('cuda', fp16=True)

pfps = 'medium' # ['low', 'medium', 'high']
video = t2v_pipe(
    'a red car is drifting on the mountain road, close view, fast movement',
    width=640, height=384, fps=fps
)
