Sometimes, I use Instagiffer to get a better look at things. It's a gif-making program, but it lets you look at things frame-by-frame. You can put a Youtube link into the text box where you load a video, and you can load a video that you have saved on your computer. If you find a frame you like, you can export the frame to save it. Of course, you should rename the image before exporting another frame, or it'll just get overwritten.

I've actually also discovered a way to go through a video frame-by-frame in Windows Media Player. It's pretty cool.
