In your browser, open YouTube and locate the video you want. Copy its URL to the clipboard.
Run YouTube Downloader or Cmd-Tab (Alt+Tab on Windows) to it and paste the URL into the program using the corresponding button on the toolbar:
You can add multiple videos the same way.
Now we need to tell the program that we want to upload those YouTube clips to iTunes. Click the Preferences icon at the bottom of the window and choose Preferences from the menu. Go to the Video output tab.
Set the Add to iTunes options as shown above. Close the Preferences window.
Everything is ready, so just click the Start button on the toolbar to process all videos at once, or click individual buttons next to each video if you want to download only this given clip.
Now, the program will download the videos from YouTube and put them into iTunes library automatically converting all necessary settings along the way. Isn’t that magic?
We have successfully downloaded YouTube videos to iTunes with minimum hassle. If you want to open the local copies of the downloaded files, click the magnifier icon near a video. Good luck!
