Raw camera tracking video with markers

I want to try out Blender’s camera tracking but I can’t a single raw video (Preferably 720p or 1080p) with the markers visible in the video. I don’t own a video camera of any kind so I really expected to find videos like this on the internet but I haven’t found anything yet.

Neat clips but perhaps a little too advanced for me. I’ll try it out though. Any other similar sites around?
