here is a short video

Hi Bobby, you had accidentally applied the radial wipe effect to the black solid.
If you do exactly what you did in the video but make sure you have the red solid selected when you add the wipe effect, it should work.

Got it…
So you have the logo that knocks a hole in the black solid as it scales down right now. What I think I’d do now is to simply add a new red solid behind the black solid to ‘fill’ the hole that the logo is making.
On that red solid, you can add the radial wipe effect similar to how I described above and you should be able to have it wipe on to reveal the logo.
You can hide the green layer and that will make it transparent rather than green. To see the transparency, click the transparency toggle switch at the bottom of the comp viewer window — it looks like a rectangle with a checkerboard, between the fast preview switch and the mask path visibility switch.

Looking back you your post, you mentioned green screen… are you planning on keying out the green to make it transparent? If so, if you were able to make it transparent without making it green, would that be preferable — note that it will be hard to key a green color with a soft fade to red.
Basically, if your ultimate plan is to make the green transparent to overlay onto video, or something else, it may be easier to just make it transparent to start with.

I may not be understanding exactly what you are trying to accomplish.
In your illustration with 3 stages (A, B, C), is the green circle representing your green RDA logo, and then its transition to red? And do you just want that logo with the color transition over a black background?
-
I will add, that if you simply want your logo to transition from red to green, your set up may not be quite right… I don’t think you need the black solid or the green background below it. I think you could do this more simply, but I may not be following your full intent.

When you apply radial wipe, I’d first adjust the completion property to be about 80% (based on your illustration). It should cut a wedge shape in your logo. If you drag the completion value you’ll see how the wedge wipes in a radial fashion.
You can drag the start angle to rotate the whole wedge shape to where you need it.
And you can scrub the center property to move the center of the radial wipe to be above your logo. To get the position right, you’ll probably want to set the completion to around 90-95% so you can see the angles better.
Once you have the center positioned, you can just animate the completion from 100% to the value that you need to reveal the whole logo.

There is an effect called Radial Wipe (Effects > Transitions) that should work for the reveal you are looking for.
You’ll animate/keframe the completion property to do the reveal and you can set it to clockwise or counterclockwise.
You’ll want to offset the wipe center to be above your logo to match your illustration.
There is also a feather property.
And as Eric pointed out, the blurry edges are due to enlarging a raster image, and either making a vector version of the logo or, as you suggested, making it higher resolution should help.

For the scale animation , select your logo layer and type an ‘s’ to reveal the scale property.
I think you wanted the logo end in the position/scale that it is on the screen, so go ton6 seconds in the timeline and click the stopwatch icon next to the scale property to enable key frames for scale and it will automatically add a key frame at that point for the current scale value.
Next, move the time cursor to the beginning of the timeline and change the scale value to the size needed. AE will automatically add a new key frame with that value.
If you play the animation the logo should now scale from one dive to the other smoothly at a constant rate
To have it slow down as it nears the final key frame, right-click the last key frame and choose key frame assistant > ease-ease.
The animation should slow as it nears the final key frame.
If you want to change the rate further, right-click the key frame again and choose key frame velocity. In the window that opens, there will be 4 values. 2 on the left should be 0 and 33.3%. Change the 33.3% to effect the rate of slowing. Higher values will be slower, lower will be faster.

Assuming your RDA 5.png has transparency, where the red is opaque and the black is transparent, then for your 1st request, you can make the opaque portion knock out the black solid below it by setting the black solid’s track matte (TrkMat) property from ‘none’ to ‘Alpha Inverted’ in the timeline.
You should then be able to see the greenscrn1.png layer at the bottom of the stack.
For request 2, it sounds like all you would need to do is animate the scale property of RDA 5.png with a few keyframes over 6 seconds… if I’m reading that correctly.
Search/read about easy-ease keyframes to learn how to slow the animation between keyframes.
