Say I want to make an animated lower third, a rectangle. I want the rectangle to expand and the text within the rectangle to appear as the rectangle expands...the text mask is revealed as the rectangle extends.

Is there an easy way to do that? It seems as though, from the hours of Googling I've gone through, it's not easy with our flavor of WPF 3.5.

Please, dear Jesus, let there be a better way for future versions of vMix!

Yes! It's quick and dirty but that's the idea (not the blue box but the white one).

Essentially, trying to make the lower third only as long as it needs to be, and give it a maxwidth so it can't go beyond a certain length.

This seems to be something totally different than your original post . from what i understand here you dont want the TEXT field to be longer . this has been addressed here before by using a viewbox where the text will reduce in size but the total lenght of the textbox will remain the same. There are other means to limit a text lenght too

the q & d effect (Yellow box) is just animating a clipping path

Here's the thought on what I am trying to do. Maybe I've been crap explaining it. (Worth nothing searching Clipping Path only garners two results, me and one other post about a ticker)

The attached shows it. Rather than the white bar being all the way across... I'd like it to max out at the length of the text, with a little padding to the side.

Perhaps the way to do it would be to have the "Blue" box in your example be white, and the textblock to not have a background color at all. But to have that blue box expand and contract with the length of the text within the text block within it.

LOL thank you for letting me know. I just realized I have my two goals confused/combined in this thread.

1: Animation where the text masks in.

2: A box that is only as big as it needs to be.

As far as which... frankly whichever is longer.

resizing your "white " background based on the lenght of your text

have the width of your "white" rectangle or border be binded to the actual length of your textbox
tweak with adding extra rectangles for the extra space needed
double this idea for the other text box so the longer text will make it look like it responds to the longest one

You need to use Clipping path.
Use youtube there a good tutorial about Expression Blend Clipping path.

1. Make a "Canvas"
2. Rectangle and text put inside a "Canvas"
3. Draw by "Pen" recatangle above "Canvas"
4. Select "Canvas" + "Pen draw", right button make clipping path
5. Go to animation then animate canvas rectagle text as you need
