Total number of frames APT could track

[Junes94]

Hi, I wonder the maximum number of frames APT could track. I have a movie of 32000 frames. When I tried to track all of the frames, it failed. (I used 49c43c0 version of APT but the error doesn't seem the matter of version) So, I gradually increased the number of frames to be tracked. 9400 frames succeeded, and 10000 frames failed. you could see the failure screenshot and logs below.

I could track all of my movie by tracking 4700 frames repeatedly. I just wonder the limitation of frames to be tracked and if someone could fix it, it would be my pleasure. Thank you.

Hey June, No there should be no limitation on the number of frames to track. It might be best if I can test directly on your project -- it's possible it's a resource issue on your machine. If that sounds good can you direct message me at allenleetc - at - gmail? Thanks, Allen

Hey June, I pushed a fix for this, let me know if you still encounter any issues! (I am still working on a tangential side issue related to the "All Frames" tracking option.) Thanks, Allen
