How to remove transparent watermark from a video ?

[aquax]

I read this guy's thread https://forum.videohelp.com/threads/337854-How-to-remove-huge-but-transparent-watermark


Original screenshot: [IMG]i.imgur.com/KSHlwQn.jpg[/IMG]

First I replaced transparent(low opacity) logo part to red [IMG]i.imgur.com/OdRYNR7.png[/IMG]

Outcome : [IMG]i.imgur.com/WrWfiZR.jpg[/IMG]


But still, it doesn't look like it's supposed to look, it should have barely see-able edges of the logo, but this method just blurred the logo.
Recently I discovered another way to remove the logo, I changed 'Sony levels' in Sony Vegas, but after that video looks too dark, so that's not an option..

Can someone recommend any working methods that would work on this kind of watermark ?

I forgot to mention that I used VirtualDub DeLogo plugin

You need to work on only the luma, and you need to use a more advanced blend mode - one that is the inverse of whatever was used to originally create it (screen/multiply/etc). And try with varying amounts of opacity on the matte (which should be grayscale, no red).

Pull a Difference mask then use that to neutralize the watermark. Divide Pie into thurds, then round it off.

Are you talking about Sony Vegas or After Effects ?
I tried this on VirtualDub DeLogo plugin.

Does anybody have any more ideas to remove this watermark ?

Maybe. Can you provide a sample where the watermark is over a black background?

I read this guy's thread https://forum.videohelp.com/threads/337854-How-to-remove-huge-but-transparent-watermark

But not very well, I'd guess. Did you try any of the tips given in that thread, especially AlanHK's?

Do you have to use VirtualDub? Did you read any of the VDub logo removal guides?

Here is the logo on a black background



I read some DeLogo removal guides. I painted the logo (opacity 50%) parts red and removed everything else that didn't had any parts of the logo over it, saved as transparent PNG, but it didn't work.. Also tried to paint logo white with opacity 60% this kinda worked on Sony Vegas with some blending modes and 'Sony Levels' effect on main video, but still wasn't as good as in the tutorials..

Script using only built in AviSynth functions:

logo = ImageSource("logo.png").ConvertToYV12()
src=ImageSource("pic.jpg").ConvertToYV12()

logo=logo.ColorYUV(gain_y=-50, off_y=-20) # adjust logo levels

Overlay(src, logo, mode="subtract") # subtract logo from image, leaves bright areas too dark
bmask=src.ColorYUV(gain_y=2000, off_y=-450).GreyScale() # mask based on brightness
Overlay(last, src, mask=bmask) # blend original with delogo'd video

The script needs to be adjusted for a wider range of the source video.

wow that is perfect.. I have never used AviSynth, I'm gonna try it now..

I replaced src=ImageSource() with AVISource() and the video is green with logo over it..

Just the first few frames? Or the entire video? What's your source container and codecs? Note that AviSource() requires a VFW decoder for the video. ffdshow includes VFW decoders for most common codecs. If you use a 32 bit editor/encoder you need to use 32 bit AviSynth and a 32 bit decoder. If you use a 64 bit editor/encoder you need to use 64 bit AviSynth and a 64 bit decoder.

I also had to convert audio from quicktime's AAC to MP3 otherwise AviSynth shows:

No compatible ACM codec to decode 0x00FF audio stream to PCM.

Finally it's kinda working after converting everything, but on darker backgrounds there are visible parts of the logo, maybe because of the heavy conversion that was done.. Is there any more parameters that I can use for removing the logo completely ?

Original source file has QuickTime container/codec (original video info) which can't be used anywhere,

You can open the mov directly in avisynth with ffms2.dll or qtsource.dll, with aac audio . I wouldn't load audio, you can just remux it from the original that way you don't lose any quality

e.g

ffvideosource("video.mov")

or

qtinput("video.mov")

Thanks, this worked, and other videos are not green anymore..

You can play around with gamma_y in ColorYUV() for the bmask. I don't think that will help much because the problem appears to be more around the logo letters, not within them.

You could try blurring those areas but I think the blurring will be too obvious. Add this to the end of my previous script:

blurry = Blur(1.0).Blur(1.0).Blur(1.0).Blur(1.0)  # a blurry version of the delogo video
edges = logo.mt_edge().mt_expand().Blur(1.0).Blur(1.0) # map of edges in the logo, feathered
Overlay(last, blurry, mask=edges) # overlay the blurry video at the edges in the logo

You'll need masktools2 for AviSynth.

Thanks for this too, a little improvement is noticeable..

@aquax

please what are the first line (1,2,3 ..) of your script

@aquax

please what are the first line (1,2,3 ..) of your script

logo = ImageSource("url to logo.png").ConvertToYV12()
src=FFVideoSource("url to my source video.mp4").ConvertToYV12()

logo=logo.ColorYUV(gain_y=-50, off_y=-20) # adjust logo levels

[jagabo]

You probably don't need the ConvertToYV12() on the output of ffVideoSource. It's most likely putting out YV12 already.

[QUOTE=poisondeathray;2396501]

you can just remux it from the original that way you don't lose any quality

What do you mean by 'remux' ? I can save/render this final video without re-encoding (I previously used MeGUI to re-encode it with avisynth settings)

That was referring to audio, not video. ie. Don't load audio into the script. It doesn't make sense to re-encode the audio.

"remux" means stream copying the original audio into the new container

I wouldn't load audio, you can just remux it from the original that way you don't lose any quality

Seems interesting but I don't know the first thing about using AviSynth, I tried it earlier on with LogoTools and it wouldn't work because I had certain missing dll files. I then tried VirtualDub with both logoaway and MSU logo removal but neither of those solutions worked, they just created a very blurry gif. For reference, ill link what I'm trying to edit the logo out of. Any solutions for my specific issue?

Should be easily removable with InpaintDelogo, I guess on that website you can find various images with same logo, if you'll find same logo on black background then it should go away without a trace.
