Quality issues with logo overlay

I have created a circular logo which I want to overlay on a video. The logo is required to spin every so often which I have achieved in after effects. I have then rendered the footage to AVI (best settings, lossless) and proceeded to overlay footage in Premiere.
The issue that I am having is that the edges of the circle and general quality is a bit rubbish. Looks like quite a low resolution. Anybody got any ideas as to how to increase the quality? The cirle does have red border if that makes any difference.

Is there any reason you didnt import the footage into afx and overlay it all together. Also, is the logo a shape layer or raster image. I am guessing the edges are a bit blocky in Premiere.

Hi Mike, thanks for replying. I think the issue is actually more to do with the red colour. After searching these forums I see that red is quite an awkward colour so I have reduced the R value which seems a lot better.
I am not sure of the best workflow with regards to AE and Premiere. Do you think that I should cut my final footage in Premiere and then load into AE for the logo overlay/transition?

Yes, that is exactly what I think. AFX seems to be much better at fine tuning your video footage. I generally import my footage using premiere, trim it down - much easier with Premiere, then export using Quicktime with animation codec. Import into AFX and do all your post work. That is how I like to work anyway. Depending on the version, you can also use the dynamic link to import premiere sequences into afx as a comp with a series of video on different layers so you can tweak them individually. Pretty handy.

Your best bet is to use black as your BG, even if giving it an alpha channel. And you should be rendering your animation straight - not premultiplied. See this video:
But even so, if you rendered premultiplied (and clearly from your description, you did) try using effect > Channel > Remove color matting and setting the color to the EXACT color you used as a BG (in your case, the red you're using). That may remove much or all of the crud.
