YouTube shows a new option for long videos: a theater view that enlarges the player and fades out the rest of the page. Randall Munroe’s talk at Google and Steve Jobs’ speech at Stanford are two examples of feature length videos that should display the new option.

You can restrict YouTube’s search results to feature length videos by appending &longform=1:

It’s not clear how YouTube filters feature length videos, but most of them are from the Authors@Google series, Standford University, Carnegie Mellon University and Vancouver Film Studios.

If you want a YouTube interface that looks more like Google Video, try the YouTube Googler Greasemonkey script.
