QT Lite is a lightweight version of QuickTime Player . It contains only the essential components for viewing QuickTime content in your browser. It's very similar to QuickTime Alternative , which means that you won’t notice it working. Nevertheless, if you want to set your own options, you have the possibility of making some adjustments regarding media encoding, synthesizer, audio playback, streaming speed and transport via a small window. Unlike the QuickTime Alternative application, this piece of software does not come with the Media Player Classic included. Other features include downloading HD QuickTime trailers by using the included MOV Download Tool, enabling support for embedded mp4 and m4a files, and the fixed configuration option at the end of the installation. QT Lite installs Apple’s Application Support on your computer if you don’t have it already, as it needs this service in order to install its plugins correctly.
