If you frequently work on AI projects or need to edit videos and extract audio, you must know these two incredibly practical tools:

  • 🎬 ffmpeg: The "Swiss Army knife" of audio and video, capable of editing, transcoding, extracting subtitles, and more—it does it all.
  • 🧰 uv: A fantastic tool for managing Python environments, letting you run various AI projects with a single command, no manual configuration needed.

Even better, both can be used directly on Windows. Just download the .exe files, extract them, and they're ready to use—no installation required, no system clutter. Set them up in minutes and instantly turn your computer into an AI experimentation platform!

🧩 Step 1: Install uv (The Python Environment Management Marvel) ​

uv is an ultra-fast, ultra-lightweight Python package manager. Simply put, it automatically downloads, installs, and runs all the libraries your AI project needs— No more manually installing Python, creating virtual environments, then running pip install one by one, potentially encountering a slew of module conflict errors!

✅ Windows Installation Steps ​

  1. Download uv

    👉 Click the link below to download the Windows version zip file:

    https://github.com/astral-sh/uv/releases/download/0.9.8/uv-x86_64-pc-windows-msvc.zip

  2. Extract the Files

    After downloading, extract the zip. You'll see a folder containing uv.exe and two other .exe files.

  3. Open the System's Special Directory

    To let your computer recognize the uv command from anywhere, we need to place these files in a specific path.

    • Open any folder (e.g., "This PC" or "Documents")

    • Click the address bar at the top and type:

      %userprofile%

      Then press Enter. This will automatically navigate to your user home directory.

  4. Copy the uv Files to That Directory

    Copy the extracted uv.exe and the other .exe files from the same folder into this directory.

    Next, open a CMD terminal. If you haven't opened one yet, press the Windows key + R, type cmd, and press Enter. Then paste the command reg add "HKCU\Environment" /v Path /t REG_EXPAND_SZ /d "%PATH%;%USERPROFILE%" /f and press Enter to execute.

    ✅ The benefit of this: You can now directly use uv in any command-line window without typing complex paths!

🍎 macOS User Installation ​

If you're using macOS, installation is even simpler. Just open "Terminal" and enter:

bash
wget -qO- https://astral.sh/uv/install.sh | sh

🎬 Step 2: Install ffmpeg (The Swiss Army Knife for Audio/Video Processing) ​

ffmpeg is an essential tool for all video professionals and AI enthusiasts. It can handle almost any audio/video task: editing, extracting audio tracks, format conversion, merging, adding subtitles... it masters them all!

✅ Windows Installation Steps ​

  1. Download ffmpeg

    Click the link below to get the full Windows build package:

    https://www.gyan.dev/ffmpeg/builds/ffmpeg-release-full.7z

  2. Extract the Files

    After downloading, extract the archive. You'll see a folder named something like ffmpeg-x.x.x-full_build (the version number may vary).

  3. Locate the Key Files

    Open that folder → navigate into the bin subfolder inside. You'll find:

    • ffmpeg.exe
    • ffprobe.exe (for querying audio/video information)
    • ffplay.exe (a simple media player)

    💡 It's recommended to copy all three files together for future convenience.

  4. Place Them in the Same Location as uv

    Copy these three .exe files to the same directory as uv:

    %userprofile%\.local\bin

    Now you can directly use ffmpeg by typing it in any command-line window!

🍎 macOS User Installation ​

macOS users can directly run the following command in Terminal:

bash
brew install ffmpeg

What if %userprofile%.local\bin is not in the PATH environment variable? ​

Open the Start Menu in the bottom-left corner, find "Command Prompt", right-click --> More --> Run as administrator. Paste this command and press Enter to execute.

reg add "HKCU\Environment" /v Path /t REG_EXPAND_SZ /d "%PATH%;%USERPROFILE%.local\bin" /f

🎉 All Done! You've Successfully Configured uv and ffmpeg! ​

👏 Congratulations! At this point, both powerful tools are installed. With this one-time setup, you can use them directly from any directory in the future.

From now on:

  • Need to process a video? Open Command Prompt (CMD) and type:

    bash
    ffmpeg -i input.mp4 -ss 00:00:10 -t 5 output.mp4

    (The example above cuts a 5-second clip starting from the 10-second mark.)

  • Want to run a Python AI project? Simply type:

    bash
    uv run script.py

Isn't it simple? Whether you're a video editing pro or a newbie AI enthusiast, these two tools will help you get twice the results with half the effort.
