Hi all:

From what I've seen in the documentation, it looks like this can't be done, but since it isn't stated explicitely, here it goes:

I'm using DeLogo to remove a square logo from a captured video. The result is okay... except that the borders of the "de-logoed" area look too sharp, i.e.: there's the normal image, and then a blurry square patch where the logo used to be, and the limit between these two areas is too sharp (see the attached file). I'd like for that separation to be smoother, more blurry.

I thought that, since the mask used to tell DeLogo where the logo is must be 100% red (255, 0, 0), perhaps one could mark the surrounding area with a less intense red, pretty much like the way masks work in Photoshop, but according to the docs, only (255, 0, 0) is accepted. Does anyone know some other way to achieve this effect?

I'm not sure what latest versions are, but docs I have for delogo say: "You can adjust the amount of blur using Deblend falloff slider"

Thanks. Unfortunately, I've given it a try and either I'm doing something wrong (I followed the instructions to the letter) or it doesn't really make much of a difference. "Don't expect miracles"... indeed. Maybe some other delogo filter gives better results in this regard?

There are a few you can find searching online, & I've tried general FX limited to the logo area with limited success in NLEs like Vegas or Prem. I've also tried feathering the mask picture used in Delogo. And I've personally never had really great success with any method, but I assume that has to do with the source video, and how the logo was originally added. I have to admit the examples I've seen look a whole lot better then anything I've been able to achieve. :confused:

Hopefully someone that's achieved those results will post here how they do it.:) I've gone to either tolerating logos, or cropping them out. :D
