Help with a logo (watermark)

[crossover475]

For a few days I've tried to remove a logo, but, I can't take it off, that's why I'm here. I tried to remove the logo with delogo, logoaway... creating the mask of the logo with photoshop , but, after all my attempts I couldn't remove it. In the original video, there are some frames with the logo, but the majority of the capture doesn't have it. I want to keep the consistency of the video without causing any serious kind of visual change. What i want to do is make it so that the logo has very little effect on the quality of the video. I will be so grateful If any of you can help me.

without logo
with logo

here's a video in case anyone wants to take a better look and possibly figure out a way to remove it.
