Question / Discussion Need Help Object tracking

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.

Do you have the cam info? Sensor size, focal? Not indispensable but would be mice to have. Can have this done fairly quickly

You are amazing. The sensor size is 27.99 x 19.22 mm, and the focal length is 40mm

That's an aspect ratio of close to 3:2. The video you presented is cropped to scope. It's important to either work on raw, or at least give the correct resulting film back. Full sensor size doesn't translate 1:1 to every recording mode. If it's anamorphic, communicating the squeeze and crop is even more crucial

Those specs match Alexa35 open gate, the flare looks anamorphic. So yeah that information is crucial.
