Jaksta is a streaming audio and video downloader for Mac. It is a tool that can monitor your web browsers and determine when a video or an audio file is being played. It can automatically start downloading that video for you. You don't have to paste any video URLs or search for the video in a different way than what you usually do. Additionally, this app should work for any website that streams video or audio.
Jaksta silently runs on the background and it only becomes active when you watch a video on your web browser. When that happens it starts downloading the video. You can set the app to ignore Shockwave videos and videos smaller than a specific number of kilobytes to avoid downloading adds and non-related content. The app also comes with a video converter. At the bottom, left part of the main window, you can choose between one of the available conversion profiles: AppleTV, GoogleTV, iPad, iPhone, iPod, Android Phone, Android Tablet and PS3.
In my testing, I was able to quickly and easily download videos from YouTube. When you open an HD video, the HD version of that video will be downloaded, which is absolutely great. I like the fact that Jaksta requires 0 user input once it is monitoring for new videos. One thing I don't like is that you can't configure it so that it doesn't start downloading videos automatically.
