iSkysoft iTube Studio is a capable program designed to help you download clips from various video sharing websites, like YouTube, Vimeo, Dailymotion, VEVO, and many others. Besides being a competent download manager, this application also allows you to convert the downloaded videos to formats compatible with various multimedia devices, such as mobile phone, iPad, iPod, Apple TV, etc.
You can work with this utility whenever you wish to play your favorite web videos in offline mode on your Mac or multimedia devices. After you download the clips, you can convert them to various formats and play them using the integrated media player.
A good aspect about this Mac program is that it also allows you to convert media files within your computer to other formats. The app lets you choose from a wide variety of output profiles, but you can also configure their settings according to your needs (select proper video and audio codecs, resolution, bitrate, etc.).
But the thing I like the most about this download manager is that it supports downloading videos with quality from 240p to 2160p. The output quality is excellent and the results are offered in a bit.
Cutting a long story short, this is the app that offered me the largest variety of features, and I definitely recommend you to try it if you intend to download clips from video sharing websites. This program comes with a fair price and offers you the output you require within moments.
