calculations with different point masses - October 5 at 1:59:PM

Hello,

I would like to deduct a vibration from the camera. For this I follow mass A (object) and mass B ("fixed point")
Is there a way to subtract Xb from Xa etc.?

Currently I'm using the measuring tool and attaching it to A and B, but this is very slow for 1000 pictures. The problem here is that when reading the trk file it takes a long time until it opens. It seems like the calculation is being done again ... aren't they saved? Pinning 2 points (500 frames FHD) takes about 5 minutes. Opening this trk file takes about 15 minutes. The entire RAM (32GB) is eaten up until the tracker is finished.

It would be much easier to set the Coordinate System|Reference Frame to Mass B.

I'm not sure why it takes so long to load the TRK when you use the tape measure tool. But with the Reference Frame you don't need a tape measure.  Doug
