Ensure that your insert clip fits the tracking footage’s comp size – by this I mean that your insert clip not only has to reside in a comp which is of the same size as the tracking footage BUT the insert clip’s edges has to hug the perimeter of the comp.

You can do this simply/quickly by selecting the footage and hitting the CTRL+ALT+F – of course do this in the precomp.

BTW, I am assuming that you’ve got a good looking track in mocha, ie no more bumps and such?

Hi RoRK,
Do you mean that my asset / insert clip, should be HUGE as is the comp? Say; 1920×1080? I am using Pre-comps, which I pre-sized the asset inside a 1920×1080 pre-comp as mentioned earlier and am not getting anything but a very small import, like a small ball of incoherent, asset. Is that what you mean? Is that why I am getting a Tiny asset or insert clip?

As far as a non bump track. I do not know what I have ended up with yet. Due to the imported track flies off target, as shown in the pics.

The Track is good in Mocha, well OK, as I had to adjust the KF’s as aforementioned in a couple other earlier replies. However, I still have a track that flies off Target.(Not in Mocha but in AE) Is that because of the pre-comp question above? Along with a weird Ripple I asked about, but was not addressed. See (Ripple Pic) I wanted to insert it into AE to get a look at the final result before re tracking over and over in Mocha and maybe that ripple won’t be seen. Take a look at at that pic (Ripple Pic)
Thanks

OK RoRK,

I got it, thanks for your help. The conflict was the fact that I was able to Use Corner Pin Data in my first part of my comp. (Separate footage, albeit same setting) Part 1 I will call it. In Part one I able to export tracking data into two different assets (not in a comp of their own) and with luck they took the tracking data and looked good. When attempting the same steps in Part 2 (the part you have been helping me with) The data would not work in bare assets as they did with luck, as I did NOT place the assets in part 1 into their respective like size comps. (Got real lucky) Hence me not being able to understand why Part 2 was such a challenge. After recreating the assets, in AI at 1920×1080 and then importing them into AE, placing them in the assets in their own comp of 1920×1080. I was left with a HUGE asset that needed to be resized. Using your shortcut shared of ALT + CTRL + “F” it centered and sized my asset to 25% of it’s imported size. I then pasted my Corner Pin Data with Supporting RG Warp into the comp and I had a good track. Thank you for your patience with me and re-assuring my steps on this.

I will say this about Mocha and their training videos, they overlooked that pre-comp step in many tutorials, along with a clear pointing out that your first track is not necessarily going to be your Spline, or asset track.
Where as in my case, I created a Solid Background Track then Linked to it using the Drop Dn menu to then adjusted and re-sized my final Spline that I used both the Planar (blue) tracker and Pink (grid) to get it dead on. Ran through it and then adjusted in (Adjust Track) Tab to further Hand KF the wobbles and hick ups. Also pointing out that a re-track is not needed as Mocha will interpret the first Track that the final spine is linked to and then adjust for Corner Pin if One is using it…

I am still a bit foggy on re-sizing my Pink Grid, once it goes to full screen (cannot find the shortcut) Not the amount of grids under View>Preferences but to shrink it back down as if just opened. Along with the difference between Corner pin with Blur or the Corner Pin with RG Warp?
In any case some one is trying to figure out errors in Mocha this last post on this thread has a bundle of information as does your input.
Best,
Simon
p.s look forward to any response on those last 2 questions?

Hi Simon, I’m glad you’ve got results that suit your needs. As for the question, it’s a requirement that the insert clip share the same size as the tracking footage. Therefore, if your insert clip is of a different size, you should then resize it in a precomp. This isn’t a mocha tracking data requirement but rather a manifestation of how the Corner Pin effect works.

There are actually two parts to the Corner Pin effect – (1) start points and (2) end points – for each of the four points. The end points are where mocha’s tracking data ends up. The start points default to the size of the comp or the size of the tracking footage. Most users fail to see the importance of the start points and this is a great cause for confusion. If you take a look at the CC Power Pin effect, it has separate start and end points that are shown clearly.
This helps to overcome a lot of the confusion as well as allowing a user to resize the insert clip via the start points. This precludes having to precomp/next the insert clip.

I’m not sure about the second question as I’ll have to take a look at all the variables before I can be certain of the issue.

Again thank you Roland, appreciate it. As important as the corner pin data is to have the same size footage or for a sign, (as most are using the tracking for signs) One would think that Imagineer’s training videos would mention that.

Well I learned quite a bit on this one.
Pre Comp for Corner Pin, Tracking not as a final spot but tracking for a solid track with the add a spline for better tracks and then adding another spline for the final tracks, the subtract matte drop down, Key framing for fine adjustments/adjusting a track, linking other assets to an Adjusted Track Spline (after spending time to dial in a spline, reuse it for another asset in the comp, if needed) what to watch for when shooting to then later track, etc…
Glad I learned this on a practice run (a buddies reel) instead of being under dead line….Thanks again for your patience.
Regards,
Simon

I’m glad things have worked out for you. I suggest that you practice more often – 1 to 2 tracks each day; starting with easier tracks and then building on your skills with more difficult tracks.
