Video stabilization(advanced for very very jittery footage)

[Stefanmz7]

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 and it looks promising but also Avid Media Composer I don't know I mean if the film industry uses it it might be even better although Final Cut is already professional so I don't know just any software or plugin that can help, I would appreciate if you tell me, thank you super super much! Seriously I need this and I cannot find a solution. Or a trick or anything. Just anything that would solve this. I need to remove the jitter completely if possible or at least have it be not noticeable. Thanks again and hope that you can find a solution that I haven't tried yet! I just don't want to waste time downloading other software if it's not gonna work so I am asking here if you have already tried it you can tell me.
