Tubulator is an easy-to-use Mac application that allows you to browse and download your favorite videos and music from Youtube. This program can prove to be a useful tool if you are a Youtube user and you want to store any desired video clip on your system as either an audio (MP3, OGG Vorbis or AAC formats) or a video (MP4 format) file.
A great thing about the Tubulator is the fact that you won't even have to launch your web browser in order to get the desired content from the Youtube website. The built-in Youtube browser will help you find everything you need simply by providing search terms, but you can also paste the links of the videos you want to download in case you have them copied to the clipboard.
Tubulator allows you to open as many tabs as you want in order to download multiple videos at the same time and, after accessing the "Preferences" menu, you can select the desired download format for both video and audio files (this application will automatically convert them after the download is finished) as well as the preferred video size (from small to HD 1080p and Highres).
Other than that, the easy-to-use Tubulator lets you add bookmarks, which can prove to be quite useful if you want to save certain videos to download them at a later time.
Overall, if you are looking for a simple Mac application that can help you download videos from the Youtube website as both video and audio files, then you might want to give the Tubulator a chance.
