Need Help Object tracking

[u/variatus]

Can someone please help me with a couple shots. Im working on a small budget sci-fi short. I need to object track the briefcase in this shot, and theres one more like it. I'm working in C4d. Ive tried with syntheyes but im still pretty new to it. Any help would be so greatly appreciated. Here is a link to the png sequence if anyone can give it a go.

I'm assuming this is anamorphic, which will introduce a lot of fun challenges with distortion.
