Having lots of trouble trying to add a white solid background layer to my animation.

So I made a paint stroke animation.

This consists of:

1. Adjustment layer

2. Paint stroke shape (which I made and just added motion and stuff here to make it look real)

 

Well, I need the file to be an mp4 but when I did this it automatically added a black background but I really need to the background to be white or transparent. 

 

When I try to add the whiter solid background as a layer in the back, it messes with my animation, it turns my adjustment layer into a dark block on top of the white background. I still see my paint stroke shape moving as it should but without any of the effects it doesn't look like the paint stroke anymore.

 

What did I do wrong???

 

See pictures below (one is with the white background hidden and the othe ris when you can see the white background)

Nevermind! If I select the adjustment layer and the paint stroke (without selecting the background) then I can right click and choose the "pre-compose" option and this will only apply the adjustment layer to the paint-stroke or logo or whatever it is!

Never use paint on an adjustment layer. An adjustment layer has no pixels. Everything you do on an adjustment layer happens to every layer below it. When you paint on a layer, it adds s colored stroke to that layer. If the layer has no pixels (an empty nested comp or an adjustment layer, you get no pixels. 

 

I don't see any need at all for the adjustment layer.

Hi, okay, I just started using After Effects today, is there an easy fix so I can get the background to be white when exporting to an mp4 without having to remove the adjustment layer and redo all the effects (I follow a youtube video to make the initial animation so I'm not very good at After Effects). Or what's the easiest way to get my animation onto a white background in an mp4 from this point?
