Downloading 4K resolution video from YouTube, only getting 360p and 720p options.

I'm trying to download a 4K video from YouTube, it has worked before with other videos, It is how I found your software.
After I paste the link and it does is parsing, I am only given the option of 360p and 720p options.

This is the link to the video I'm trying to get. http://www.youtube.com/watch?v=bYP4wKD-6J8
