Hi, you can just delete the y keyframes in After Effects.

Hi, you can but you need 2 files to make it work without writing a complicated script.
1. you need an ffx file saved somewhere to reference in a jsx file
2. you need a jsx file (like the one below) that makes a solid and references your ffx file.

This particular script only works if you have an ffx file on your desktop called myEffectsPreset.ffx (mac os, in my case)
Save this code somewhere as a jsx file.
///////////////////////////////////////////////////////////

// This first bit Makes a black solid within the selected Comp
myComp = app.project.activeItem;
mySolid = myComp.layers.addSolid([0,0,0], "Black", myComp.width, myComp.height,myComp.pixelAspect);
mySolid.startTime = 0

//This part assigns an ffx file that you have stored somewhere to the solid
var myEffectsPreset = File ("~/Desktop/myEffectsPreset.ffx");
mySolid.applyPreset(myEffectsPreset);

Hi, did you use the adjust track tab in Mocha? Also, track the whole plane in Mocha not just the area where the image is.

Hi, an alpha channel is a black and white image, which, when applied to another image, controls the transparency of the image to which it is applied. Areas of the alpha channel that are white remain visible after the alpha channel is applied. Areas that are black become transparent. For example if you have an image of a rose against a sky, and another image which shows a white silhouette of the same rose against a black background, if you apply the silhouette image as an alpha channel (in a program that understands alpha channels, like After Effects) to the colour image of the rose, the result is a rose with transparency all around it behind which you can add a new background.
And that’s it

Hi How did you invert your transform. try pickwipping anchor point to position and position to anchor point between the comp with the stabilization and the comp where you revert the stabilization. Make sure that in the comp in which you revert the stabilization that collapse transformations is turned on.

Hi, for those frames where there is a shadow, keyframe your mask(s) to not include the trouble area before letting mocha make its calculations.

Hi, to make AE masks move with mocha tracker data, export transform data rather than cornerpin data.

If there is just a few pixels of fluctuation from frame to frame, Mocha will track that perfectly well.

Hi, if I understand it correctly, I think what you would need is
Layer 1. Solid with mask
Layer 2. The footage with effect applied (set to Alpha Matte)

Then bring this comp into another comp with a cleanplate of the footage.

As an aside, although it is hard to get used to at first, for more versatility in doing compositing style shots in AE, precompose everything (especially mattes) and keep your project panel very organised.

Hi Jordan, by the way in my first post I said tracking but I meant masking. I guess that’s what I get for responding at 4am 😉
