The 720p version of the video should be available but you may have to reload the video to get that option. Click on the gear icon in the bottom right part of the video player to find the 720p setting.
I hope to eventually put together a more extensive video that covers a start-to-finish project, starting with preparing the images in Lightroom, blending in Photoshop, and polishing the image in both Lightroom and Photoshop.
