VideoCrafter：A Toolkit for Text-to-Video Generation and Editing

🔆 Introduction (Showcases)

🤗🤗🤗 VideoCrafter is an open-source video generation and editing toolbox for crafting video content.
It currently includes the following THREE types of models:

1. Base T2V: Generic Text-to-video Generation

We provide a base text-to-video (T2V) generation model based on the latent video diffusion models (LVDM). It can synthesize realistic videos based on the input text descriptions.

"Campfire at night in a snowy forest with starry sky in the background."	"Cars running on the highway at night."	"close up of a clown fish swimming. 4K"	"astronaut riding a horse"

2. VideoLoRA: Personalized Text-to-Video Generation with LoRA

Based on the pretrained LVDM, we can create our own video generation models by finetuning it on a set of video clips or images describing a certain concept.

We adopt LoRA to implement the finetuning as it is easy to train and requires fewer computational resources.

Below are generation results from our four VideoLoRA models that are trained on four different styles of video clips.

By providing a sentence describing the video content along with a LoRA trigger word (specified during LoRA training), it can generate videos with the desired style(or subject/concept).

Results of inputting A monkey is playing a piano, ${trigger_word} to the four VideoLoRA models:

"Loving Vincent style"	"frozenmovie style"	"MakotoShinkaiYourName style"	"coco style"

The trigger word for each VideoLoRA is annotated below the generation result.

3. VideoControl: Video Generation with More Condition Controls

To enhance the controllable abilities of the T2V model, we developed conditional adapter inspired by T2I-adapter. By pluging a lightweight adapter module to the T2V model, we can obtained generation results with more detailed control signals such as depth.

input text: Ironman is fighting against the enemy, big fire in the background, photorealistic, 4k

🤗🤗🤗 We will keep updating this repo and add more features and models. Please stay tuned!

⚙️ Setup

Choose one of the following three approaches.

1. Install Environment via Anaconda (Recommended)

conda create -n lvdm python=3.8.5
conda activate lvdm
pip install -r requirements.txt

2. Install Environment Manually

CLICK ME to show details

conda create -n lvdm python=3.8.5
conda activate lvdm
pip install torch==1.12.1+cu113 torchvision==0.13.1+cu113 -f https://download.pytorch.org/whl/torch_stable.html
pip install pytorch-lightning==1.8.3 omegaconf==2.1.1 einops==0.3.0 transformers==4.25.1
pip install opencv-python==4.1.2.30 imageio==2.9.0 imageio-ffmpeg==0.4.2
pip install av moviepy
pip install -e .

3. Install Environment with xFormers

Useful for saving GPU memory

conda create -n lvdm python=3.8.5
conda activate lvdm
pip install -r requirements_xformer.txt

CLICK ME to check the cost of GPU memory and sampling time

We tested the sampling_text2video.sh on RTX 3090 and A100 GPUs in two environments. The minimum requirement for GPU memory is at least 7GB.

GPU Name	CUDA Version	Environment	GPU Memory	Sampling Time (s)
RTX 3090	10.1	no xformer	8073M	30
↑	↑	with xformer	6867M	20
A100	11.3	no xformer	9140M	19
↑	↑	with xformer	8052M	17

↑ indicates the same as the previous row.

💫 Inference

1. Text-to-Video

1. Download pretrained T2V models via Google Drive / Hugging Face, and put the model.ckpt in models/base_t2v/model.ckpt.
2. Input the following commands in terminal, it will start running in the GPU 0.

  PROMPT="astronaut riding a horse" 
  OUTDIR="results/"

  BASE_PATH="models/base_t2v/model.ckpt"
  CONFIG_PATH="models/base_t2v/model_config.yaml"

  python scripts/sample_text2video.py \
      --ckpt_path $BASE_PATH \
      --config_path $CONFIG_PATH \
      --prompt "$PROMPT" \
      --save_dir $OUTDIR \
      --n_samples 1 \
      --batch_size 1 \
      --seed 1000 \
      --show_denoising_progress

CLICK ME for more options

• gpu_id: specify the gpu index you want to use
• ddp: better to enable it if you have multiple GPUs
• We also provide a reference shell script for using multiple GPUs via PyTorch DDP in sample_text2video_multiGPU.sh

2. VideoLoRA

1. Same with 1-1: Download pretrained T2V models via Google Drive / Hugging Face, and put the model.ckpt in models/base_t2v/model.ckpt.

2. Download pretrained VideoLoRA models via this Google Drive / Hugging Face (can select one videolora model), and put it in models/videolora/${model_name}.ckpt.

3. Input the following commands in terminal, it will start running in the GPU 0.

  PROMPT="astronaut riding a horse"

4. If your find the lora effect is either too large or too small, you can adjust the lora_scale argument to control the strength.

   CLICK ME for the visualization of different lora scales

   The effect of LoRA weights can be controlled by the lora_scale. local_scale=0 indicates using the original base model, while local_scale=1 indicates using the full lora weights. It can also be slightly larger than 1 to emphasize more effect from lora.

   scale=0.0	scale=0.25	scale=0.5
   scale=0.75	scale=1.0	scale=1.5
