🎥 How to Build Your Own Screen Recorder Using CMD and FFmpeg (No Software Needed)

screen-recorder-using-cmd-and-ffmpeg-windows

Want to record your Windows screen without installing bulky apps? This tutorial shows you how to create a screen recorder using Command Prompt (CMD) and FFmpeg — the powerful, open-source video tool used by professionals.

No GUI. No bloatware. Just a clean command-line method to capture your screen and save it as an MP4 file — in just one command.

Let’s get started.


🛠️ What You’ll Need

  • 💻 A Windows PC (any version with CMD)
  • 📦 FFmpeg installed and added to PATH
  • 🗂️ A folder to save your screen recordings

🧰 Step 1: Install FFmpeg (If You Haven’t Already)

  1. Go to the official site:
    🔗 https://ffmpeg.org/download.html

  2. Download the Windows build (e.g., from gyan.dev).

  3. Extract the ZIP file to a folder, like C:\ffmpeg\.

  4. Add FFmpeg to system PATH:

    • Open Start Menu → search for Environment Variables
    • Under "System Variables", select Path → click Edit
    • Add: C:\ffmpeg\bin

✅ Done! You can now run ffmpeg commands directly from CMD.


📁 Step 2: Choose Your Output Folder

Pick a folder where you want your screen recordings saved.

Example:

D:\MyRecordings

Open that folder in File Explorer.


💻 Step 3: Open CMD Inside the Folder

Click on the address bar at the top of the folder window and type:

cmd

Press Enter. This opens Command Prompt in that folder so your output files will save directly there.

🧠 No need to type paths manually — super handy trick!


🎥 Step 4: Run the Screen Recording Command

Paste this into CMD:

ffmpeg -f gdigrab -framerate 30 -i desktop recording.mp4

Here’s what it does:

  • -f gdigrab: Uses Windows desktop capture
  • -framerate 30: Records at 30 frames per second
  • -i desktop: Sets input source to your full desktop
  • recording.mp4: The name of your output file

🔴 Your screen is now being recorded!


🛑 Step 5: Stop the Recording

When you’re ready to stop:

  1. Focus on the CMD window.
  2. Press the q key
  3. Hit Enter

That’s it — the file recording.mp4 is saved in your folder!


📝 Important Notes

  • This method only captures videonot audio.
  • It records your entire desktop, not just a window.
  • File size depends on screen resolution and recording length.

🎯 Final Output Example

If your folder is D:\MyRecordings, you’ll find:

D:\MyRecordings\recording.mp4

Double-click it to preview your screen capture.


⚠️ Common Errors & Fixes

🔄 ‘ffmpeg’ is not recognized as an internal or external command

➡️ This means FFmpeg isn’t added to PATH. Double-check Step 1 or use the full path like:

"C:\ffmpeg\bin\ffmpeg.exe" -f gdigrab -framerate 30 -i desktop recording.mp4
