Stable Video Diffusion Training Code ๐
We have attempted to incorporate layout control on top of img2video, which makes the motion of objects more controllable, similar to what is demonstrated in the image below. The code and weights will be updated soon.
Init Image | Gen Video |
---|---|
size=(512, 320), motion_bucket_id=127, fps=7, noise_aug_strength=0.00
generator=torch.manual_seed(111)
Init Image | Before Fine-tuning | After Fine-tuning |
---|---|---|
Note that BDD100K is a driving video/image dataset, but this is not a necessity for training. Any video can be used to initiate your training. Please refer to the DummyDataset
data reading logic. In short, you only need to modify self.base_folder
. Then arrange your videos in the following file structure:
self.base_folder
โโโ video_name1
โ โโโ video_frame1
โ โโโ video_frame2
โ ...
โโโ video_name2
โ โโโ video_frame1
โโโ ...
This training configuration is for reference only, I set all parameters of unet to be trainable during the training and adopted a learning rate of 1e-5.

While the codebase is functional and provides an enhancement in video generation(maybe? ๐คท), it's important to note that there are still some uncertainties regarding the finer details of its implementation.
- Support text2video (WIP)
- Support more conditional inputs, such as layout
