Your search area is far too big and is overlapping multiple planes. Looking at your frame, I would assume that you will be able to get a track by simply drawing your search shape around the small rectangle to the right of the door. Otherwise the depth from the door itself and the fact that their is no detail on the wall to track will certainly throw this off.
Once this is tracked, than you can than adjust the surface (the blue box) to position the text on to the wall.
I would recommend watching some more mocha tutorials including the mocha Fundamentals:

I do not know Resolve features that well yet, but I would assume you could render many mocha masks as colors and then use color keys from this external source.
The nice thing of Ben’s workflow is it simply channels the RGB into channels without any more setup.

Hi Margus,
You can simply render as many B&W mattes out of mocha as you want and connect them as external mattes in Resolve. mocha can render the mattes with variable feathered edges and motion blur.I think the cool feature that Ben showed in the mentioned video was to get 3 separate matte files out in one file by rendering them full Red, Green, Blue colors and then using each as a separate secondary.
Most users would simply use separate black & white mattes, but this RGB method speeds up the render and reduces the data.

Hi Juan,
The ideal workflow is to be able to paste (or import) the mocha mask data directly into Resolve like we do for After Effects, Premiere, Nuke, Fusion and Flame/Smoke. Resolve currently does not have a mask format that is easily written to. If you’d like to contact the Resolve team and ask for better mocha integration, that might help push the issue’s priority. I assume with Fusion acquisition, that better vfx integration is something they will work on. 😉Imagineer has also thought about an OFX plug-in, so it might be something for the future. 😉
I might also add here, that new Boris FX OFX plug-in for Resolve has an excellent feature available now: import mocha tracking data. This way a Resolve user could import planar tracking data for screen inserts or sky replacements.
I would love to hear from more Resolve users that want to use mocha and Resolve together.
Cheers,

mocha can actually handle out of focus footage if the shape is large enough and you crank up the % of pixels used. However, like the other responses say – at some point you may need to resort to manual tracking.
Best of luck,

That is a bit cynical way to look at it. There are many companies around the world that specialize in roto and are using mocha for this task. In general mocha will be much faster than manual roto. That said, it is best to understand mocha by watching some tutorials before jumping in blind.
For in-depth and complex roto, you will not want to use the rotobrush as there is little ability for artist intervention when it does not work. For most roto jobs, you as the artist need to make the decisions, but there are advanced techniques that include combining keying and masking to save time.
I would highly recommend watching some of the videos at Imagineer Systems and start with this video series: https://www.imagineersystems.com/video/?tagFilter=mocha%20Fundamentals&&dd=dateOld&orderby=date&order=ASC
Good luck.

When I see issues described “1/2 the height” I suspect that you are working with a de-interlaced project.
If possible, check your project setting and to troubleshoot, re-export this source clip as sequential frames and re-import into mocha in a frame based non-interlaced project.
Beyond this, it is best to log a support case:

Are you choosing de-interlace on import?
To troubleshoot this, I would export your footage out of AE as an image sequence and import to mocha without de-interlacing.
I suspect the issue is in the QT file header.

You should download and install:
mocha 3D track importer for AE
https://www.imagineersystems.com/download/current-version-downloads/When you have the camera data exported (pasted to your clipboard) and the plug-in is installed, you will find the paste mocha camera in edit menu in AE.

Have you contacted Imagineer support? This workflow should work fine in CS5. If you view your surface in mocha, is the track data looking correct?
