Compressing Digital Video
Apple's Compressor, from the Final Cut Studio, is a complete video compression software that is intended to give you a whole host of different compression options. This ranges from just compressing to smaller QuickTime files for regular digital viewing, compression for DVD authoring, for iPod distribution, and other formats. If you want to upload your video to a sharing service, such as YouTube or Vimeo, then you are going to have slightly different requirements of your video compression. With that in mind there are some specific avenues and processes for compressing your video for streaming online viewing. Here is a basic tutorial on how to compress your videos for online publication through Apple's Compressor.

Below will be the codec options for compressing your video file, and these will range from optional presets to codecs by name. Open up the Apple folder and then find the Other Formats one. In here you are going to want to go down and find Web, which is at the bottom of the available folders under Podcasting.
Since you are trying to find the best compression rate for streaming video go to Streaming, which is below Download and above Web Videocast. Here you are going to have two options: QuickTime 6 Compatible and QuickTime 7 Compatible. This choice is really going to be up to you. If you are operating a newer QuickTime format then QuickTime 7 Compatible should be fine, otherwise QuickTime 6 Compatible will be good. It is generally a good idea to go with QuickTime 7 Compatible in most cases.
Once you open up your chosen folder you will have five possible compression rates ranging from H.264 100 Kbps Streaming to H.264 LAN Streaming. This essentially ranges from the smallest compression rate among the streaming, which is H.264 100 Kbps Streaming, to the largest, which is LAN Streaming. How you choose among the five is also going to be regulated by how large you can allow your file to be and how much room you will have on your streaming server. If you are using a format like YouTube or Vimeo you should be fine with the LAN Streaming format, but if you need to compress and upload a whole host of files then you may want to go with one of the tighter compression codecs.

Once you do choose a compression codec then just drag it up to where your project was listed above. Set a destination where you want the compressed file to end up and then hit the submit button. You can watch the progress of the compression in the Batch Monitor, and this may take a little while since this is a much more involved compression than some of the others.
