Video Data Processing

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
    ├── video_name1
    │   ├── video_frame1
    │   ├── video_frame2
    │   ...
    ├── video_name2
    │   ├── video_frame1
        ├── ...

Training Configuration(on the BDD100K dataset)

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.

accelerate launch train_svd.py \
    --pretrained_model_name_or_path=/path/to/weight \
    --per_gpu_batch_size=1 --gradient_accumulation_steps=1 \
    --max_train_steps=50000 \
    --width=512 \
    --height=320 \
    --checkpointing_steps=1000 --checkpoints_total_limit=1 \
    --learning_rate=1e-5 --lr_warmup_steps=0 \
    --seed=123 \
    --mixed_precision="fp16" \
    --validation_steps=200

Disclaimer

While the codebase is functional and provides an enhancement in video generation(maybe? 🤷), it's important to note that there are still some uncertainties regarding the finer details of its implementation.

TODO List

• Support text2video (WIP)
• Support more conditional inputs, such as layout
