Having camera solving problems (need answer soon!)

HeySiri Posts: 382 Just Starting Out*

Okay my deadline is tomorrow and I still have lots of work to do so I'm done just playing around with Hitfilm I just need someone's help.

So I'm working with this shot:


Now, the ominous figure is chroma keyed in. The camera moves forward in the shot and it's handheld. I'm trying to get the figure to move in parallax with the camera when the camera moves in so that it actually looks like the figure is a part of the shot and not just floating around.

I've tried camera solving in both Mocha and Foundry and I'm still getting significant drift on the figure. I've also tried using tracked 2d points in Hitfilm but it's just not working and I don't know what to do.
