[Cassidy Cagle] “For this particular project I have done several tracks previously with PNG files
and have successfully transferred the info to AE where I of course pasted the data to a null and parented a text comp to this Null”
You only paste mocha tracking data onto a Null in AE if you are exporting transform tracking data. When exporting Corner Pin tracking data, you will of course paste the tracking data onto either a full-frame Solid (for matting) or a video layer (an insert without a matte).
When you transfer the data to the Null in AE, did you (1) delete all the Anchor Point keyframes (2) reset the Anchor Point value to [0,0]? The second step while not absolutely necessary, ensures that the Null follows your tracking data in absolute terms rather than relative. This makes it much easier to confirm that the tracking data is accurate BEFORE you parent any layer to the Null.
Once you can confirm that the Null is accurate, this will help you to troubleshoot issues with the child layer.
For now, ensure that you’ve applied the two steps above and check that there are no Transform KFs on the Text Comp/Layer – then repost.
