After Effects Rainbox Build
I am an After Effect Begginer. I know the very basics and keyframes and the concept of layers. That is abount it.
I have a nice logo with a rainbow. I would love to have the rainbow build. Can anyone point me in the right direction to make that happen? Thanks!

Using the pen tool, draw a mask (onto the rainbow layer) that is arch-shaped. You only need two points for this. Next, apply effect>render>stroke to the rainbow. Adjust the brush size until it’s nice and fat for now. Next change the effect’s paint style to “reveal original image”. Adjust the position of the mask and the brush width until the entire rainbow can be seen.
Now to reveal the rainbow, use keyframes to animate the “end point” value of the stroke from 0 to 100.
If you want to reveal each band of colour separately, you can create six coloured solids, each with a mask and stroke as above, then animate their reveals separately.
Hope that helps,

neat solution…..
i would have been animating masks
great tip and i like the way you think -
Stroke is righteous. 🙂

Or you just use the radial wipe effect – just apply and animate one parameter. It’s tyte for any circular reveals (such as rainbows)
Hope that helps!

Yes. The transition effects have many applications, often overlooked.
