Without any more specific info about your project we can't tell you much. The 3D tracker is notoriously difficult and prone to all sorts of errors nad certainly things liek the ongoing AE disk cache issues don't make things easier... You could simply be seeing one of those just as you could run into a footage specific issue with some CoDec that doesn't work that well on PC. We simply can't know based on so little information.
Sorry for this issue. Did you ever find a solution? Please let us know if you have or if you still need help.
I have exactly same problem.
I have test same footage on Windows 7/Windows 10 with AE 2017/AE 2018.
Stuck at Solving Camera
But when I use lower spec Macbook and Hackintosh.
Your problem could be the format of the footage. Compressed MPEG footage is notorious for decompression problems. Try transcoding to a proper production format or an image sequence.
but same footage I can work on Mac version, but its not working on windows.
should I still transcoding?
just hoping there is there some further info on this issue ?
I'm having the same problem, trying to 3D Camera Track some cineform files. They're quite short, 30-40 secs, steadicam shots that I would expect the tracker to easily solve.The exact same files solve without any hassle under OSX but hang forever in "solving camera" phase in Windows 10. It's almost as if the solve has failed but the banner hasn't updated as the analysis server CPU use drops to 0%. Or perhaps its some kind of caching issue as Mylenium suggests, quite often AE will crash not long after this solve hang happens ?
any suggestions on how to proceed greatly appreciated.
cineform alpha files (in an admittedly odd res and aspect) 1440x2496
on a side note: I first encountered this back in 2015 (Camera Tracker duration or data limit ? ), back then I was still mostly using Macs but have recently returned to the land of Windows... and apparently the land of 3D Camera tracking frustration !
so, I've now tried a vast array of codec types, none of which are able to be tracked under Windows !
yet all (well, those able to be decoded by quicktime) worked flawlessly under OSX !!!
what gives ?
