Revealing/hiding text through video elements
on May 2, 2015 at 10:50:18 am

Hi

I'm trying to do the following effect: like this video for example: (between 8 and 12 seconds)






But I want instead to reveal text when a car passes...then Hide the text when another car passes

I tried to figure out how to do it with masks...I created a sequence in after effects,
-put the video as the bottom layer.
-Added text above
-duplicated my video
-placed on top of the text layer
-masked the area where the action happens

The effect works but the text gets hidden all at once (without a revealing effect)

questions:

any idea how to do it?

should I add single letters and add opacity key-frames to hide/reveal ?

I would be very appreciative for your support

Regards
Anthony

You're very close.

Just think about what is masked on the video, what it will do, and how to trim in and out points on text layers and video layers and you will have it.

Better to think it through so the learning sticks rather than be told... especially when you're so close.

Dave!
Thanks for not helping me :D hehe

I figured it out! I added key-frames for the Mask Path

I really appreciate your advice (Better to think it through so the learning sticks rather than be told... especially when you're so close.)
