I was actually preparing this as one of my first tutorials! I haven’t watched this yet, but figured I’d share it since there’s no point reinventing the wheel. If my technique was drastically different I’ll still do it.
Here’s a tutorial I found for camera motion tracking in Blender and compositing in 3d models. It’s good if you’ve never done it before, but it also covers the upcoming version of Blender so a good update for people who already know the basics.
One quick tip which the host forgot to mention: if you are using beta builds of Blender 2.8, don’t open or save files you’ve worked on in previous versions since you may loose compatibility.
