We are using After Effects CC2015 version 184.108.40.206. The Program crashes and shuts down while using 2D Tracker. We are having the very same problem on different computers and on different footages. Program crashes on both Win7 and Mac 10.01.2 systems. Our footage formats are variable. Crashed occured either on 16 bit dpx sequence or DNxHD 444 10 bit. Can this be a bug? Anyone having or encountered this same problem?
For the problem file types, are the pixel aspect ratios square? It's alway wise to work in square pixel aspect ratios.
Is this happening when you stop the motion tracking when it's in progress? If so, this is a known issue that we are in the process of fixing.
Yes, program crashes as you mentioned. But yesterday, the problem we had on several computers before, only happened when tracking
