| # Make-A-Video Stable Diffusion JAX | |
| We have extended a pretrained LDM inpainting image generation model with temporal convolutions and attention. | |
| By taking advantage of the extra 5 input channels of the inpaint model, we guide the video generation with a hint image. | |
| In this demo the hint image can be given by the user, otherwise it is generated by an generative image model. | |
| The temporal layers are a port of [Make-A-Video PyTorch](https://github.com/lucidrains/make-a-video-pytorch) to FLAX. | |
| The convolution is pseudo 3D and seperately convolves accross the spatial dimension in 2D and over the temporal dimension in 1D. | |
| Temporal attention is purely self attention and also separately attends to time. | |
| Only the new temporal layers have been fine tuned on a dataset of videos themed around dance. | |
| The model has been trained for 80 epochs on a dataset of 18,000 Videos with 120 frames each, randomly selecting a 24 frame range from each sample. | |
| See model and dataset links in the metadata. | |
| Model implementation and training code can be found at <https://github.com/lopho/makeavid-sd-tpu> | |

| **Please be patient. The model might have to compile with current parameters.** | |
| This can take up to 5 minutes on the first run, and 2-3 minutes on later runs. | |
| The compilation will be cached and consecutive runs with the same parameters | |
| will be much faster. | |
| Changes to the following parameters require the model to compile | |
| - Number of frames | |
| - Width & Height | |
| - Inference steps | |
| - Input image vs. no input image | |
| - Noise scheduler type | |
