Image logo distorts when rendering in 'progressive-scan'

Good day!

I have encountered a problem when rendering my movie: the logo I put on the top-right gets distorted when I switch to 'Progressive' in the Adobe Media Encoder in either FLV or WMV format.

But the logo is crystal clear when I allow interlaced processing, but that messes up the video instead with those interlaced lines. So that's a no-no also. Is there any solution to this? It would be very much appreciated. I tried experimenting, even to the point of exporting the image to various formats.

Here are the pictures btw:

Is the logo a static graphic keyed in the video or is it video with alpha? The only two possible reasons I can think of are:

1. The logo has some pretty thin lines, which are going to get crunched when you resize and compress. Not much you can do about that other than to blur the logo slightly or try to fatten up those lines a little.

2. If it's video with alpha, does it match the interlacing of the project? If there's a mismatch there (it's interlaced and the video is progressive), you'd see the problem noted.

Other than those two things...I can't think of a reason why it would look that much different.

It would also help to give more the specs of the original video and you're keying the graphic (noted above), what you're compressing to size-wise and codec wise etc.
