The effect you're looking for is called Motion Tracking. It's not exactly putting it "in", rather it's selecting a point in the video and having the image, text, etc. attached to it following the same key frames you'll see in the video. There are a number of tutorials on this subject, but I recommend this one: https://www.youtube.com/watch?v=-RzUUOGG7pw
They go into detail without any additional fluff so you can learn exactly what you're looking for. I hope that helps.
