What sort of footage are you using it on?
You can try transcoding it to ProRes, Cineform, or DNxHD and then try using the new footage in there.
Unfortunately, I have tried it on all different types of footage/codecs and it still won't track any of them.
Well that's just odd.
Try an older version (like CC 2014) and see if it behaves. If so, great! You can carry on working in the older version or simply save your project and open it in the new version.
Are you still facing this problem? If not, let us know how you solved it. If so, please let us know so we can assist you further.
No, I have still not been able to figure it out. Any suggestions?
Have you tried it in CC 2014 as I suggested? (Your CC subscription includes older versions including CS6, CC, CC 2014, CC 2015, and CC 2015.3 - all of which can be installed simultaneously alongside each other with no issues.) Here's a page on downloading older versions (the option is not where it looks like it should be).
I have not. While that may work for the short term, it is definitely not a long term solution.
Agreed, but it can be a useful troubleshooting step.
Hey, the adobe support just helped me solve this. Rename the folders of the preferences in Library/Preferences/Adobe to "_old" or move them so after effects has to write them again.
These are the folders in the lib/prefs that tech support renamed:
Same goes for the folder in user/Documents/Adobe/dynamiclinkmediaserver - add an old or whatever you want to that folder name and it resets with the next start of after effects.
