  • If you run out of credits, simply cycle through the other platforms.

Method 2: Local Deployment of SoraWatermarkCleaner (Unlimited Use)

Use this open-source GitHub project to process locally on Windows. You will need PowerShell with administrative privileges.

Prerequisites

  • Git: Download from https://git-scm.com
  • A functional Python environment (uv will handle the details).

Installation Steps

  1. Install FFmpeg
    Run this in PowerShell:
winget install Gyan.FFmpeg

Verify:

ffmpeg -version

2. Install uv (Python Package Manager)
Run:

irm https://astral.sh/uv/install.ps1 | iex

Verify:

uv --version

3. Clone the Project and Install Dependencies
Run:

cd C:\Users
git clone https://github.com/linkedlist771/SoraWatermarkCleaner.git
cd SoraWatermarkCleaner
uv sync

4. Activate Virtual Environment
Run:

.venv\Scripts\Activate.ps1
If you encounter an execution policy error, run this first:
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

Running the App

Ensure your virtual environment is active:

.venv\Scripts\Activate.ps1

Launch the application:

streamlit run app.py

Open http://localhost:8501 in your browser (it takes about 2 minutes to load the model on the first run). Upload your video and download the processed output.

Downloading Models (if auto-download fails)

Create the resources directory:

mkdir resources

Download the YOLO weights:

Invoke-WebRequest -Uri "https://github.com/linkedlist771/SoraWatermarkCleaner/releases/download/V0.0.1/best.pt" -OutFile "resources\best.pt"

The Lama model will download automatically from the Torch cache.
