One thing I do is apply the expression to a slider or text layer and comment out everything after the variable I want to track. Not great, but it works.

OK – I see where you’re going. I think your time remap expression is going to end up looking something like this:
revTime = 4; //time for 1 revolution of object (seconds)
v = position – thisComp.layer(“Camera 1”).toWorld([0,0,0]);
a = radiansToDegrees(Math.atan2(v[2], v[0]));
linear(a,0,360,0,revTime)I haven’t tried it, so it may not be exactly right and you may have to change a sign or add an offset to get it all lined up.

Why not just position the camera and object layer, make the object layer the parent of the camera, then rotate the object layer to match the rotation of the object within the footage? Would that work?

With scripting, you would use the setValueAtTime() method to create keyframes for the text layer’s Source Text property – either setting the value to the subtitle text at the start time or to blank at the end time. Something like that.

No, expressions can’t do file I/O. It would need to be in AE’s scripting language, which is based on JavaScript. You need AE 6.5 Pro though.

You should be able to import and parse a text file in one of those formats with a script. It would probably work best if you already had a blank text layer all set up with your font, size, color, positioning and justification choices.
The script wouldn’t be trivial, but it shouldn’t be too tough either.
