As its name implies, this program was created to help you download and convert clips from YouTube. The utility lets you choose from a wide variety of media formats, comes with an integrated YouTube browser, preserves the quality of videos, and much more.
You can work with this application whenever you wish to watch a YouTube video in offline mode (without an Internet connection). The utility downloads clips in resolutions like 1080p or 720p and then converts them to any of the selected output profiles.
Another advantage is that you can import videos from your local directories and convert them to other media formats. You can load as many input files as you need and immediately convert them to the desired output format.
Unfortunately, this program occasionally fails to download YouTube clips. For some reason, it displays "Network error!" message. The developers stated that this issue was solved within this version; sadly, it wasn't.
With that being said, I'd suggest you to try another YouTube downloader for Mac. There are plenty of other programs that don't encounter the aforementioned download error and come with a cheaper price.
