MakeLongVideo - Pytorch

Implementation of long video generation based on diffusion model.

Setup

Requirements

python3 -m pip install -r requirements.txt

Training

Prepare Stable Diffusion v1-4 pretrained weights

download from huggingface and put it in directory 'checkpoints' which is configured in configs/makelongvideo.yaml

Download webvid dataset

download webvid dataset into directory 'data/webvid' using https://github.com/m-bain/webvid repo. Then prepare dataset using command

python3 genvideocap.py

Download LAION400M dataset

download laion400m into directory 'data/laion400m'

Train

first train using resolution 128x128

accelerate launch --config_file ./configs/multigpu.yaml train.py --config configs/makelongvideo.yaml

then finetune in resolution 256x256, modify last line of configs/makelongvideo256x256.yaml according to your local epoch checkpoint

accelerate launch --config_file ./configs/multigpu.yaml train.py --config configs/makelongvideo256x256.yaml

Inference

Pretrained weights: https://huggingface.co/xiexiecn/MakeLongVideo

# unwrap checkpoint first
TORCH_DISTRIBUTED_DEBUG=DETAIL accelerate launch train.py --config configs/makelongvideo.yaml --unwrap ./outputs/makelongvideo/checkpoint-5200

inference directly

python3 infer.py  --width 256 --height 256 --prompt "a panda is surfing"

inference using latents initialized by sample video

python3 infer.py  --width 256 --height 256 --prompt "a panda is surfing" --sample_video_path your_sample_video

inference by sample frame rate 6 (actual frame rate is 24/6==4)

python3 infer.py  --width 256 --height 256 --prompt "a panda is surfing" --speed 6

Todo

• generate 24 frames video of 256x256
• add fps control
• release pretrained checkpoint
• remove watermark
• improve resolution to 512x512
• 1~2minutes video generation
• make story video
