Chat Expression Rig Questions

[Kany5CCF]

Hey everyone, I posted a couple of things about this topic before, but at the time I wasn't the most well-versed with what kind of product I wanted. 

I'm wondering if anyone is able to aid me in creating a chat animation expression rig or the likes. I attached a video of my end result : 

Everything in the video I created, however I did it manually, and it ends up always taking me up to two hours to complete a full song. I need to be able to churn out a lot of these videos in a small amount of time, so I've been looking for a way to automate it. Really, any help at all is so greatly appreciated.

You could use an expression to center the text on a shape-layer background using sourcceRectAtTime(). You could also use the layer's in-point and interpolation to move each layer up when a new layer or pair of layers are added to the timeline. 

I don't have time to write the expressions for you. Seems to me that I already answered a similar question on the forum recently and provided the expression basics. If I get sometime later I'll look for that reply.

The code will have to be modified to account for multiple lines and background shape layers. I don't have time to do that for you. Let me know if you need more help.
