Hi Shake isn’t sold on the PC platform anymore. The last version for PC is Shake 2.5 I believe. That would work fine if you can get your hands on it. Nuke would work too. You could get a 30 trial of Nuke for PC and just do the tracking in Nuke, then bring over the tracker info to AE. It is a bit involved if you aren’t used to it.
I forgot to mention, try tracking just the red or green channel, or just the luminance channel by converting to yuv space, also try degraining the footage first, add a little blur, add contrast and don’t forget to precompose everything.
Let me know if you need some more help.
