    Hi,

    I have seen videos that had logos and then were removed but I don't know how they did it.
    The videos are on youtube and when someone rips it and put hardcoded subs onto the video, s/he also removed the logo that was present on the upper right of the video without leaving any smudge or blurry marks.
    Check out these screenshots of the original video and the hardsubbed video.

    Can someone please tell me how I can remove logos without leaving any mark? I want to get the results as in the screenshots.
    I can't live without my computer.

  2. There are lots of logo removers that can remove translucent logos very well. There are no logo removers that can remove opaque logos without leaving crap, except in special circumstances (flat backgrounds, static backgrounds, etc.).

    In the case of the image you posted you can just overlay another part of the flat(ish) background over the logo. Or you in inpaint from the area around the logo. Your first image after Dekafka(70, 42, 116, 110, 255), an infiller, in AviSynth:

    But how do I overlay another part of the background over the logo when the video is changing scenes?
    Can you show me the steps?
    I don't know how to use AviSynth.
    And what are the good logo removers that are free?

    You can't -- that's why I said "in special circumstances." Using that white blob in the top right corner of the image you posted as an example:

    Code:
    clean = crop(202,40,24,32) # the area just below the blob, coordinates are x, y, width, height
    Overlay(last, clean, x=202, y=8) # overlaid over the blob

    But if there was more detail there that wouldn't work well.

  5. Does this work moving logos or is it for static logos only?

  6. What you mean by "moving" logos? A logo that changes position on the screen? An animated logo (that otherwise stays in the same location)? And which "this" are you asking about? I mentioned several things.

    The technique in the AviSynth script I gave only works if there is a portion of the frame that can be copied over the logo without creating an obvious discontinuity. In the sample image the background just below the white smudge as about the same color and intensity as the background around the white smudge. So I was able to copy that bit of background over the smudge seamlessly. That's why it's a "special circumstance". That will not work with most video where things are moving around or with more complex backgrounds. For example, it wouldn't work with this:

    There's nothing else in the picture that would seamlessly hide the logo.
