## Project Introduction
[](https://hub.docker.com/r/eritpchy/video-subtitle-remover)
Video-subtitle-remover (VSR) is an AI-based software that removes hardcoded subtitles from videos.
It mainly implements the following functionalities:
- **Lossless resolution**: Removes hardcoded subtitles from videos and generates files without subtitles
- Fills in the removed subtitle text area using a powerful AI algorithm model (non-adjacent pixel filling and mosaic removal)
- Supports custom subtitle positions by only removing subtitles in the defined location (input position)
- Supports automatic removal of all text throughout the entire video (without inputting a position)
- Supports multi-selection of images for batch removal of watermark text

```shell
sudo apt update && sudo apt install python3.12 python3.12-venv python3.12-dev
```
#### 2. Install Dependencies
It is recommended to use a virtual environment to manage project dependencies to avoid conflicts with the system environment.
(1) Create and activate the virtual environment:
```shell
python -m venv videoEnv

#### 3. Create and Activate Project Directory
Change to the directory where your source code is located:
```shell
cd
```
> For example, if your source code is in the `tools` folder on the D drive and the folder name is `video-subtitle-remover`, use:
> ```shell
> cd D:/tools/video-subtitle-remover-main
> ```
#### 4. Install the Appropriate Runtime Environment
This project supports four running modes: CUDA (NVIDIA GPU acceleration), CPU (no GPU), DirectML (AMD, Intel and other GPU/APU acceleration), and macOS (Apple Silicon).
##### (1) CUDA (For NVIDIA GPU users)
> Make sure your NVIDIA GPU driver supports the selected CUDA version.
- Recommended CUDA 11.8, corresponding to cuDNN 8.6.0.
- Install CUDA:
- Windows: [Download CUDA 11.8](https://developer.download.nvidia.com/compute/cuda/11.8.0/local_installers/cuda_11.8.0_522.06_windows.exe)
- Linux:
```shell
wget https://developer.download.nvidia.com/compute/cuda/11.8.0/local_installers/cuda_11.8.0_520.61.05_linux.run
sudo sh cuda_11.8.0_520.61.05_linux.run
```
- CUDA is not supported on MacOS.
- Install cuDNN (CUDA 11.8 corresponds to cuDNN 8.6.0):
- [Windows cuDNN 8.6.0 Download](https://developer.download.nvidia.cn/compute/redist/cudnn/v8.6.0/local_installers/11.8/cudnn-windows-x86_64-8.6.0.163_cuda11-archive.zip)
- [Linux cuDNN 8.6.0 Download](https://developer.download.nvidia.cn/compute/redist/cudnn/v8.6.0/local_installers/11.8/cudnn-linux-x86_64-8.6.0.163_cuda11-archive.tar.xz)
- Follow the installation guide in the NVIDIA official documentation.
- Install PaddlePaddle GPU version (CUDA 11.8):
```shell
pip install paddlepaddle-gpu==3.0.0 -i https://www.paddlepaddle.org.cn/packages/stable/cu118/
```
- Install Torch GPU version (CUDA 11.8):
```shell
pip install torch==2.7.0 torchvision==0.22.0 --index-url https://download.pytorch.org/whl/cu118
```
- Install other dependencies:
```shell
pip install -r requirements.txt
```
- For Linux systems, you also need to install:
```shell
# for cuda 12.x
pip install onnxruntime-gpu==1.22.0
# for cuda 11.x
pip install onnxruntime-gpu==1.20.1 --index-url https://aiinfra.pkgs.visualstudio.com/PublicPackages/_packaging/onnxruntime-cuda-11/pypi/simple/
```
> For more details, see: [Install ONNX Runtime](https://onnxruntime.ai/docs/install/#install-onnx-runtime-gpu-cuda-12x)
##### (2) DirectML (For AMD, Intel, and other GPU/APU users)
- Suitable for Windows devices with AMD/NVIDIA/Intel GPUs.
- Install ONNX Runtime DirectML version:
```shell
pip install paddlepaddle==3.0.0 -i https://www.paddlepaddle.org.cn/packages/stable/cpu/
pip install -r requirements.txt
pip install torch_directml==0.2.5.dev240914
```
##### (3) CPU Only (For systems without GPU or those not wanting to use GPU acceleration)
- Suitable for systems without GPU or those that do not wish to use GPU.
```shell
pip install paddlepaddle==3.0.0 -i https://www.paddlepaddle.org.cn/packages/stable/cpu/
pip install torch==2.7.0 torchvision==0.22.0
pip install -r requirements.txt
```
##### (4) Running on macOS (Apple Silicon)
- Suitable for macOS (Apple Silicon) devices
- For macOS (Intel), please use the CPU mode. Forcing GPU usage will only be slower.
- On macOS (Apple Silicon), the accuracy of the PP-OCRv4-Server model for subtitle detection seems suboptimal. We recommend using an alternative model.
```shell
pip install paddlepaddle==3.0.0 -i https://www.paddlepaddle.org.cn/packages/stable/cpu/
pip install torch==2.7.0 torchvision==0.22.0
pip install -r requirements.txt
```
> Tested with Python 3.13
#### 4. Run the program
- Run the graphical interface
```shell
python gui.py
```
- Run the command line version (CLI)
```shell
python ./backend/main.py
```
## Common Issues
1. How to deal with slow removal speed
You can greatly increase the removal speed by modifying the parameters in backend/config.py:
```python
MODE = InpaintMode.STTN # Set to STTN algorithm
STTN_SKIP_DETECTION = True # Skip subtitle detection, skipping may cause missed subtitles or damage to frames without subtitles
```
2. What to do if the video removal results are not satisfactory
Modify the values in backend/config.py and try different removal algorithms. Here is an introduction to the algorithms:
> - InpaintMode.STTN algorithm: Good for live-action videos and fast in speed, capable of skipping subtitle detection
> - InpaintMode.LAMA algorithm: Best for images and effective for animated videos, moderate speed, unable to skip subtitle detection
- Using the STTN algorithm
```python
MODE = InpaintMode.STTN # Set to STTN algorithm
# Number of neighboring frames, increasing this will increase memory usage and improve the result
STTN_NEIGHBOR_STRIDE = 10
# Length of reference frames, increasing this will increase memory usage and improve the result
STTN_REFERENCE_LENGTH = 10
# Set the maximum number of frames processed simultaneously by the STTN algorithm, a larger value leads to slower processing but better results
# Ensure that STTN_MAX_LOAD_NUM is greater than STTN_NEIGHBOR_STRIDE and STTN_REFERENCE_LENGTH
STTN_MAX_LOAD_NUM = 30
```
- Using the LAMA algorithm
```python
MODE = InpaintMode.LAMA # Set to LAMA algorithm
LAMA_SUPER_FAST = False # Ensure quality
```
> If you are not satisfied with the subtitle removal results, you can check the training methods in the design folder, use the code in backend/tools/train to train, and then replace the old model with the trained model.
3. 7z file extraction error
Solution: Upgrade the 7-zip extraction program to the latest version.
