Final Cut stabilization

[ladybug]

Hi! So I have a very jittery footage that I want to stabilize in FinalCut. I have currently tried a combination of the built in stabilization which is fantastic and also Lock and Load X, 100 dollar plugin for stabilization(I haven't purchase it yet it's on a 15 day trial don't worry) and combining both helps but there is more work to do. Do you know some particular plugin for Final Cut or even a different program that helps specifically with jitter. The video is stable there is just microstutters which are constantly happening because I am zooming like 400 percent from the original footage(it's shot further away) but in a previous video which also had the same problem the built in stabilization worked perfectly and made it completely stable, However here because it's even more jittery it cannot. How do I fix it? I saw Topaz Labs Video AI 5 and since it includes AI I thought it might be more promising and because it uses AI the auto features might work better, but I don't know what do you think?
