Help with a logo (watermark)

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.

Thanks everyone.

upload a PNG of your photoshoped logo mask and post some of your scripting attempts. The logo uses an alpha channel so you should be able to retain some details if done correctly. Use of ReplaceFramesSimple should make your script simpler once you have the logo removed.

I'm sorry, you see, the thing is that i was using meGUI to preview the script and since none looked good enough i did not save them. But luckily i saved a couple of masks. Here's one:


The other mask is exactly the same, the only difference is that the red part is in white.
Thank you for your help.


Here's a link to the actual mask, since it's 2.6Mb no image host allows me to upload it. Mask.

Never done logo removal, but I do know that the mask should be black and white. Here is my lame attempt, I recommend using rm_logo(). Upload the mask as Black&White and convert it to PNG, most image hosting sites will take it, because of the reduced file size.

Code:
source = ImageReader("6071.png",0,0, pixel_type="RGB32")
masked = ImageReader("Logomask.bmp",0,0, pixel_type="RGB32").ConvertToRGB32()

ConvertToBW = masked.GrayScale().Levels(0,2.0,96,0,255)

LogoMask = Mask(ConvertToBW,ColorKeyMask(ConvertToBW,$FFFFFF, 50))

source.Subtitle("Before", align=5)
last + Layer(source, LogoMask, "subtract", 75).Subtitle("After", align=5)
Your next step is to make a note of the frame ranges where the logo exists. Once you do that then you can use rm_logo(). here is a logo removal example using rm_logo().
