<br>
<em>Kandinsky Video is a text-to-video generation model, which is based on the FusionFrames architecture, 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.</em>
</p>



## Pipeline

<p align="center">
<img src="__assets__/pipeline.jpg" width="800px"/>
<br>
<em>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.</em>
</p>


**Architecture details**

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


## How to use

Check our jupyter notebooks with examples in `./examples` folder
### 1. text2video

```python
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
)
```
