Graywolf teased us a bit in his video entry here, and below about a technique that can set your YouTube thumbnail image. Here’s his video.

So, does it work? I tested it out, after trying the math in my head. I’m probably wrong, but we’ll see.

It worked! See the black video overlay with the message?

This post from Crunchnotes, and the comments, are postulating that it is the center/middle of the video. That’s what I did above. However, YouTube says here that it’s not possible.

How do I change the default thumbnail for my video?
While we may add this feature in the future, there is currently no way to change the screen shot that we capture from your videos for thumbnails.

The other theory is that you can set something called a “poster frame” in your video editing tool. I did not try that, and a quick look around in my Sony Vegas DVD software package tutorial and I can’t find anything about how to do that.

20,000 points to anyone who can solve this mystery?

Got a Digg for me?
