The following instructions are designed to help you compress and save your finished video as a Quicktime file in iMovie. If you are not using iMovie, Please ask your technical support to help create a 320x240 Quicktime movie. When you are finished with this process you will be ready to send the video to post on Educast. We are presently limiting the videos on our site to 50Mb. The settings below yield videos that are 3.3 Mb per minute. If you have something larger just contact us and we will provide you different compression options.
