In AE, Mocha, how to get mask to track evenly when the corner points don't exist ?

[Letty2019]

Still working this one... hours of frustration.

In Mocha, trying to mask the bus ad so I can replace it.  It moves from left to right.

I'm replacing the bench ad with a new bench ad.

Here is how it starts:

I made an estimate of where the left side would be.

But when I track it,  the left and right side goes out of whack and I get this:

If I manually adjust the splines, they never come out perfectly square, because I have to "guess" where the bench ad will be, because it goes out of frame.

Has to be a perfect mask, because I'm replacing the image, and when the mask goes crooked, the new ad image bends and warps.

I tried the "AdjustTrack"  and it gave me the 4 red points, but how can I install the 4 points, when 2 of my starting points are out of the frame?  I tried, didn't work.

The tutorials all have masks that are entirely in the frame. 

My left side starts out of frame, and the right side later goes out of frame.

I've seen 6 videos on AdjustTrack in Mocha and I can't find one with my problem.

Thanks for your help and time! or a tutorial referral would be great.

Found some simple tutorials to extend the track point when it goes out of frame.

One simple track that goes out of frame:

Going way, way out of frame:

This doesn't help me, because I need 3D motion tracking,  but, if you have a 2D image that goes in and out of frame, this is it.

Thanks for sharing a useful video https://www.youtube.com/watch?v=N1SbVsFktmw. This video solved my problem within 15 minutes.

Isn't that great?  Works great for 2D,  waiting to see what Rick posts for a 3D solution.

this is awesome. But  i am confused is it a 2D or a 3D ? how it will work for a 3D graphics? Any major difference or the same process?

I just sent you a private message. Let me know as soon as you can and I'll post the workflow for your specific shot.

The ball is in your court! 

Thanks!

Here is the pic for the bench.  

It's missing from the left to corner, but that part of the bench never shows in the clip. I had to create this by slicing to sections of a screen shot together. Not perfect, but enough to make it work.

[Letty2019]

Here's the clip for ya! (in case you don't have it)  Looking forward to it.

[Rick Gerard]

Used a screen recording of your shot and came up with this in just a few minutes. I'll add it to a tutorial I'm working on and post it soon.

[Letty2019]

I'm dying over here!  How did ya do that??

[Letty2019]

Did you use AdjustTracking in Mocha, and manually move the corners out of frame?    I couldn't do that, but maybe there is a way to do it in the Effects Controls?  Just a wild guess. 

[Rick Gerard]

Tutorial should be ready later today. It will explain everything.

What's your youtube channel url ?  I couldn't find it.  Thanks!!

[Rick Gerard]

My YouTube Channel - It's a little disorganized but should clean up soon.

The Stabilized Power Pin tutorial is ready. It should help you figure out your shot.

Enjoy
