You're not going to get better results by recording it slower. You are not understanding the purpose 3D tracking. 3D tracking is used to put a CGI object in a scene  so that the CGI object sticks to the ground. I'm imagining that you want to put something like a character in this scene. If you want to have the character move through the entire scene then 3D tracking won't keep up in a single track. You may, however, be able to track the scene for one or two seconds. Let's say you have a shot that is moving down a street and around a corner. There is a tree on the right side of street. You can usually track successfully from where the tree enters the scene to where the tree leaves the scene. That's about it. Then you have to cut the shot and start again.
You also need detail for tracking to work. Game backgrounds have tied textures and repeating lines. These confuse the heck out of tracking software. What do you see in this frame from your movie that has enough detail to track? There' not much that can be used for 3D info.
Your only chance is to cut the shot up into short sections, track those, then put the scene back together later. It's not going to be a one click solution.
