# Enhance CogVideoX Generated Videos with VEnhancer
This tutorial will guide you through using the VEnhancer tool to enhance videos generated by CogVideoX, including
achieving higher frame rates and higher resolutions.
## Model Introduction
VEnhancer implements spatial super-resolution, temporal super-resolution (frame interpolation), and video refinement in
a unified framework. It can flexibly adapt to different upsampling factors (e.g., 1x~8x) for spatial or temporal
super-resolution. Additionally, it provides flexible control to modify the refinement strength, enabling it to handle
diverse video artifacts.
VEnhancer follows the design of ControlNet, copying the architecture and weights of the multi-frame encoder and middle
block from a pre-trained video diffusion model to build a trainable conditional network. This video ControlNet accepts
low-resolution keyframes and noisy full-frame latents as inputs. In addition to the time step t and prompt, our proposed
video-aware conditioning also includes noise augmentation level σ and downscaling factor s as additional network
conditioning inputs.
## Hardware Requirements
+ Operating System: Linux (requires xformers dependency)
+ Hardware: NVIDIA GPU with at least 60GB of VRAM per card. Machines such as H100, A100 are recommended.
## Quick Start
1. Clone the repository and install dependencies as per the official instructions:
```shell
git clone https://github.com/Vchitect/VEnhancer.git
cd VEnhancer
## Torch and other dependencies can use those from CogVideoX. If you need to create a new environment, use the following commands:
pip install torch==2.0.1 torchvision==0.15.2 torchaudio==2.0.2
## Install required dependencies
pip install -r requirements.txt
```
Where:
- `input_path` is the path to the input video
- `prompt` is the description of the video content. The prompt used by this tool should be shorter, not exceeding 77
words. You may need to simplify the prompt used for generating the CogVideoX video.
- `up_scale` is the upsampling factor, which can be set to 2, 4, or 8
- `target_fps` is the target frame rate for the video. Typically, 16 fps is already smooth, with 24 fps as the default
value.
- `noise_aug` controls the strength of noise augmentation, typically set to 250
- `steps` indicates the number of optimization steps, usually set to 15. If you want faster model generation, you can
reduce this number, but the quality will significantly decrease.
The code will automatically download the required models from Hugging Face during execution.
Typical runtime logs are as follows:

# VEnhancer で CogVideoX によって生成されたビデオを強化する
このチュートリアルでは、VEnhancer ツールを使用して、CogVideoX で生成されたビデオを強化し、より高いフレームレートと高い解像度を実現する方法を説明します。
## モデルの紹介
VEnhancer は、空間超解像、時間超解像（フレーム補間）、およびビデオのリファインメントを統一されたフレームワークで実現します。空間または時間の超解像のために、さまざまなアップサンプリング係数（例：1x〜8x）に柔軟に対応できます。さらに、多様なビデオアーティファクトを処理するために、リファインメント強度を変更する柔軟な制御を提供します。
VEnhancer は ControlNet の設計に従い、事前訓練されたビデオ拡散モデルのマルチフレームエンコーダーとミドルブロックのアーキテクチャとウェイトをコピーして、トレーニング可能な条件ネットワークを構築します。このビデオ ControlNet は、低解像度のキーフレームとノイズを含む完全なフレームを入力として受け取ります。さらに、タイムステップ t とプロンプトに加えて、提案されたビデオ対応条件により、ノイズ増幅レベル σ およびダウンスケーリングファクター s が追加のネットワーク条件として使用されます。
## ハードウェア要件
+ オペレーティングシステム: Linux (xformers 依存関係が必要)
+ ハードウェア: 単一カードあたり少なくとも 60GB の VRAM を持つ NVIDIA GPU。H100、A100 などのマシンを推奨します。
## クイックスタート
1. 公式の指示に従ってリポジトリをクローンし、依存関係をインストールします。
```shell
git clone https://github.com/Vchitect/VEnhancer.git
cd VEnhancer
## Torch などの依存関係は CogVideoX の依存関係を使用できます。新しい環境を作成する必要がある場合は、以下のコマンドを使用してください。
pip install torch==2.0.1 torchvision==0.15.2 torchaudio==2.0.2
## 必須の依存関係をインストールします。
pip install -r requirements.txt
```
2. コードを実行します。
```shell
python enhance_a_video.py --up_scale 4 --target_fps 24 --noise_aug 250 --solver_mode 'fast' --steps 15 --input_path inputs/000000.mp4 --prompt 'Wide-angle aerial shot at dawn, soft morning light casting long shadows, an elderly man walking his dog through a quiet, foggy park, trees and benches in the background, peaceful and serene atmosphere' --save_dir 'results/'
```
次の設定を行います：
- `input_path` は入力ビデオのパスです。
- `prompt` はビデオの内容を説明するプロンプトです。このツールで使用されるプロンプトは短く、77 単語を超えないようにする必要があります。CogVideoX の生成ビデオのプロンプトを適宜簡略化することをお勧めします。
- `up_scale` はアップサンプリング係数で、2、4、8 に設定できます。
- `target_fps` はビデオの目標フレームレートです。通常、16 fps であれば十分にスムーズですが、デフォルト値は 24 fps です。
- `noise_aug` はノイズ増幅の強度を制御し、通常は 250 に設定します。
- `steps` は最適化ステップ数を示します。通常 15 に設定されますが、より速いモデル生成を望む場合はこの値を減らすことができますが、品質が大幅に低下します。
コードの実行中に、必要なモデルは Hugging Face から自動的にダウンロードされます。

# 使用 VEnhancer 对 CogVdieoX 生成视频进行增强
本教程将要使用 VEnhancer 工具 对 CogVdieoX 生成视频进行增强, 包括更高的帧率和更高的分辨率
## 模型介绍
VEnhancer 在一个统一的框架中实现了空间超分辨率、时间超分辨率（帧插值）和视频优化。它可以灵活地适应不同的上采样因子（例如，1x~
8x）用于空间或时间超分辨率。此外，它提供了灵活的控制，以修改优化强度，从而处理多样化的视频伪影。
VEnhancer 遵循 ControlNet 的设计，复制了预训练的视频扩散模型的多帧编码器和中间块的架构和权重，构建了一个可训练的条件网络。这个视频
ControlNet 接受低分辨率关键帧和包含噪声的完整帧作为输入。此外，除了时间步 t 和提示词外，我们提出的视频感知条件还将噪声增强的噪声级别
σ 和降尺度因子 s 作为附加的网络条件输入。
## 硬件需求
+ 操作系统: Linux (需要依赖xformers)
+ 硬件: NVIDIA GPU 并至少保证单卡显存超过60G，推荐使用 H100，A100等机器。
## 快速上手
1. 按照官方指引克隆仓库并安装依赖
```shell
git clone https://github.com/Vchitect/VEnhancer.git
cd VEnhancer
## torch等依赖可以使用CogVideoX的依赖，如果你需要创建一个新的环境，可以使用以下命令
pip install torch==2.0.1 torchvision==0.15.2 torchaudio==2.0.2
## 安装必须的依赖
pip install -r requirements.txt
```
2. 运行代码
```shell
python enhance_a_video.py \
--up_scale 4 --target_fps 24 --noise_aug 250 \
--solver_mode 'fast' --steps 15 \
--input_path inputs/000000.mp4 \
--prompt 'Wide-angle aerial shot at dawn,soft morning light casting long shadows,an elderly man walking his dog through a quiet,foggy park,trees and benches in the background,peaceful and serene atmosphere' \
--save_dir 'results/'
```
其中:
- `input_path` 是输入视频的路径
- `prompt` 是描述视频内容的提示词，本工具使用的提示词更短，不能超过77个单词，您可以适当简化 CogVideoX 生成视频的提示词。
- `up_scale` 是上采样因子，可以设置为 2, 4, 8
- `target_fps` 是目标视频的帧率，通常来说，16帧就已经流畅，24帧是默认值
- `noise_aug` 是噪声增强的强度，通常设置为250
- `step` 是优化步数，通常设置为15，如果你想更快的生成模型，可以调低，但是质量会大幅下降。
代码运行过程中，会自动从Huggingface拉取需要的模型
运行日志通常如下:

/share/home/zyx/.conda/envs/cogvideox/lib/python3.10/site-packages/open_clip/factory.py:88: FutureWarning: You are using `torch.load` with `weights_only=False` (the current default value), which uses the default pickle module implicitly. It is possible to construct malicious pickle data which will execute arbitrary code during unpickling (See https://github.com/pytorch/pytorch/blob/main/SECURITY.md#untrusted-models for more details). In a future release, the default value for `weights_only` will be flipped to `True`. This limits the functions that could be executed during unpickling. Arbitrary objects will no longer be allowed to be loaded via this mode unless they are explicitly allowlisted by the user via `torch.serialization.add_safe_globals`. We recommend you start setting `weights_only=True` for any use case where you don't have full control of the loaded file. Please open an issue on GitHub for any issues related to this experimental feature.
