Hi all. First time on the forum, long time Mocha user.
I have an 800 frame, 4k Arri CLog shot I agreed to track/solve for a client. The shot looked so ridiculously simple — a dolly push in on a woman sitting cross legged in a hallway. No camera movement, no pan, no rotation. I agreed immediately. An hour’s work at most…
I’ve uploaded a 1080 mp4 preview to Dropbox here (there’s no blanking in the original I’m trying to track):
It’s a horror/thriller movie. The goal is to be able to fill the two side walls with… whatever… spreading roots, veins, dripping blood… who knows. My brief is to deliver a perfectly tracked, corner-pinned precomp for each wall section, that can be filled with whatever the client chooses.
I’ve done this a thousand times before and saw no hazards. My first, obvious attempts were dreadful. I was surprised. I started applying the Poplin Special approach of tracking offset coplanar detail along the skirting board etc. I tried using small segments of wall texture that persist and adding to the track so Mocha is looking at multiple pieces of the wall.
I’ve tried perspective and even the “new” adjust track.
I’ve even tried a 3D camera solve. Mocha couldn’t do it.
I put it into C4D and it was much better, but still not good enough.
AE’s solve was poor quality, even after moving into rec709 and adjusting contrast/sharpness.
People, nothing is working. I have drift that won’t obey tweaking. I have jitter and swelling of the plane that shouldn’t be there. I’ve keyframed my adjust tracking as sparsely as possible.
I don’t want someone to do this for me. I’m embarrassed that it’s beating me.
What I’d really appreciate is an expert take on how I should be thinking about this track. What am I doing so wrong?
Any help greatly appreciated. Maybe Mary wants to make a YouTube weekly use case out of it? I can supply the original 4k clip as necessary.
Many thanks in advance.
