Dynamic text box, fade up word by word

[johnmcmullin]

I have a client that wants an mogrt with an option to fade up text, word by word, with a dynamic box behind that fades up with each word. It's using a particular font that isn't monospaced.

So, using text animators doesn't work for me, because the text source rectangle size doesn't change as each word fades up.

So I thought about animating the text line as an expression. This works ok for the boxes except that there are no dissolves. Text and boxes just cut on.

If there a solution for this? I thought about using the CC Wide time effect but I can't seem to produce a smooth fade between the words.

Many thanks,

John

Perhaps some screenshots would help to understand your issue To me it sounds like you would still use a text animator to jump from word to word, but do the fading using an animated track matte or effect applied on top the text layer on its own separate layer. You know, transferring a buffer using a composite effect and using source opacity on some effects/ the compositing options. It's probably doable, it may just be tricky to get it to work with the timing and inside an MOGRT.

Thanks Mylenium,

I seem to have got it to work now. So I'd got the box to animate with the text but didn't have the fades. So I precomped it and managed to use the cc wide time effect to make it fade. There had been a bug that made it fade up in a jerky way but for some reason putting a tiny animated solid in the subcomp, completely masked out, made it render properly. 

Seems to me that it's about time Adobe made a box something you can add in the character dialogue. Even Premiere has it.
