gonna just take pictures of video signals on my ancient oscilloscope.

This is what a composite signal looks like on an oscilloscope when you are on the Super Mario Kart title screen. Note that the TV is actually using RGB, the scope is just showing the equivalent composite signal. This contains the color in YUV space, as well as the black and white brightness signal, and the sync.
the sync is the solid green line where it dips way down.
The bit right after that is the color burst, where the color signal is stuffed.
The rest is, I believe, the luminance of the scanline in question. each of those little segments at the base of the stuff above is actually a scanline. each scanline is terminated by hsync, and you are seeing the hsync's in there too.

Next up is an annotated version of this picture, as I understand it. Note that I may be wrong, I have no professional experience in this. if you notice anything glaringly wrong, I know that as anons on 4chan you will be quick to call me a dumbass and you will then be helpful by telling me where I was wrong.
