Once you click ‘OK’, the plugin will generate keyframes to populate the tracking parameters in the plugin. Each point in the Tracking Data section is a point from the layer surface that automatically updates when you modify it inside Mocha.Ĭreate Tracking data. You can then see the output of its surface back in the After Effects interface. To choose a layer to create tracking data from, click the ‘Create Track Data’ button in the Tracking Data section of the plugin.Then choose either the name or the cog of the layer you want to read tracking data from in the dialog that appears. Let’s review the workflow to use our Mocha tracking data:We select the Chosen Layers…to pick which Mocha layer we want to convert to AE. OK, if the data isn’t saved it might not be applying, or if your layer is trimmed to the wrong section the same might be true.
Are any effects applied to the layer before Mocha that may alter the frame length?. Do you have any time stretch on the layer?. Does your frame offset in Mocha match the frame offset in After Effects?. Sometimes the frame rate or frame offset can be misaligned, especially if you’ve cropped down the layer, edited the timing or trimmed the composition. Close and save mocha, and then apply the corner pin to the precomped layer you’ve lined up. This will make the surface the same size as the source footage dimensions Go back into Mocha and on the frame you’ve set your insert position, click “Align Surface”, which is the small blue icon with the arrows projecting out to the edges of the button. Apply the mocha corner pin to the precompĪlternatively, if you’ve already lined up the image in After Effects to match where you want it, you can change the Mocha surface to match:. Precomp the layer so the scaling remains intact. Scale your insert image to be the same size as the composition by using Layer > Transform > Fit to Comp. After Effects applies corner pin effects based on the dimensions of the image, not the comp, so it can become disorted if the layer hasn’t been scaled. 
Is the insert in After Effects the same size and dimensions as the source footage/comp? This is usually the issue.
Hi try the usual culprits first and work from there:
