First of all a note from me. Thank you guys for your support, feedback, and journey through discovering the nascent, innate potential of video Diffusion Models.
@damo-vilab Has released a repository for finetuning all things Video Diffusion Models, and I recommend their implementation over this repository. https://github.com/damo-vilab/i2vgen-xl
62e33a713e863650.mp4
This repository will no longer be updated, but will instead be archived for researchers & builders that wish to bootstrap their projects. I will be leaving the issues, pull requests, and all related things for posterity purposes.
Thanks again!

It is recommended to install Anaconda.
Windows Installation: https://docs.anaconda.com/anaconda/install/windows/
Linux Installation: https://docs.anaconda.com/anaconda/install/linux/
conda create -n text2video-finetune python=3.10
conda activate text2video-finetunepip install -r requirements.txtAll code was tested on Python 3.10.9 & Torch version 1.13.1 & 2.0.
It is highly recommended to install >= Torch 2.0. This way, you don't have to install Xformers or worry about memory performance.
If you don't have Xformers enabled, you can follow the instructions here: https://github.com/facebookresearch/xformers
Recommended to use a RTX 3090, but you should be able to train on GPUs with <= 16GB ram with:
- Validation turned off.
- Xformers or Torch 2.0 Scaled Dot-Product Attention
- Gradient checkpointing enabled.
- Resolution of 256.
- Hybrid LoRA training.
- Training only using LoRA with ranks between 4-16.
You can use caption files when training on images or video. Simply place them into a folder like so:
Images: /images/img.png /images/img.txt
Videos: /videos/vid.mp4 | /videos/vid.txt
Then in your config, make sure to have -folder enabled, along with the root directory containing the files.
You can automatically caption the videos using the Video-BLIP2-Preprocessor Script
The configuration uses a YAML config borrowed from Tune-A-Video reposotories.
All configuration details are placed in configs/v2/train_config.yaml. Each parameter has a definition for what it does.
I highly recommend (I did this myself) going to configs/v2/train_config.yaml. Then make a copy of it and name it whatever you wish my_train.yaml.
Then, follow each line and configure it for your specific use case.
The instructions should be clear enough to get you up and running with your dataset, but feel free to ask any questions in the discussion board.
Please read this section carefully if you are training a LoRA model
You can also train a LoRA that is compatible with the webui extension.
By default it's set to 'cloneofsimo', which was the first LoRA implementation for Stable Diffusion.
This ('cloneofsimo') version you can use in the inference.py file in this repository. It is not compatible with the webui.
To train and use a LoRA with the webui, change the lora_version to "stable_lora" in your config if you already have one made.
This will train an A1111 webui extension compatibile LoRA.
You can get started at configs/v2/stable_lora_config.yaml and everything is set by default in there. During and after training, LoRAs will be saved in your outputs directory with the prefix _webui.
If you do not choose this setting, you will not currently be able to use these in the webui. If you train a Stable LoRA file, you cannot currently use them in inference.py.
To continue training a LoRA, simply set your lora_path in your config to the directory that contains your LoRA file(s), not an individual file.
Each specific LoRA should have _unet or _text_encoder in the file name respectively, or else it will not work.
You should then be able to resume training from a LoRA model, regardless of which method you use (as long as the trained LoRA matches the version in the config).
- Use LoRA files that were made for SD image models in other trainers.
- Use 'cloneofsimo' LoRAs in another project (unless you build it or create a PR)
- Merge LoRA weights together (yet).
python train.py --config ./configs/v2/train_config.yamlWith a lot of data, you can expect training results to show at roughly 2500 steps at a constant learning rate of 5e-6.
When finetuning on a single video, you should see results in half as many steps.
After training, you should see your results in your output directory.
By default, it should be placed at the script root under ./outputs/train_<date>
From my testing, I recommend:
- Keep the number of sample frames between 4-16. Use long frame generation for inference, not training.
- If you have a low VRAM system, you can try single frame training or just use
n_sample_frames: 2. - Using a learning rate of about
5e-6seems to work well in all cases. - The best quality will always come from training the text encoder. If you're limited on VRAM, disabling it can help.
- Leave some memory to avoid OOM when saving models during training.
The inference.py script can be used to render videos with trained checkpoints.
Example usage:
python inference.py \

--prompt "a fast moving fancy sports car" \
--num-frames 60 \

Please feel free to open a pull request if you have a feature implementation or suggesstion! I welcome all contributions.
I've tried to make the code fairly modular so you can hack away, see how the code works, and what the implementations do.
