New Video Format

Students that have been on the site for a long time may have noticed higher video quality in the releases over the last three months. We've been using a new video codec that makes the file size a little bit larger, but is of higher quality. This new codec is also what is needed to make the site viewable by portable media devices (such as an iPod or iPad). All of the past videos are now reincoded and on the site. I suspect you'll find videos now and again that are incorrectly labeled... please let me know if you find any errors. I'll let you know when we're finished making the edits to make the site viewable on your portable devices. Thank you.
