I looked at the lgd and it does not look exactly the same as in your video. The video logo looks like it's a bit stretched. Aside from learning how to making a lgd file or trying to resize the video and adjusting the placement of the logo so that the two logos are more or less identical, I suggest just finding a frame were the logo is over something dark and then using InpaintDelogo.

Edit:

So, I got curious and learned how to make an ldg file. Downloaded the English version of aviutl (v1.14), loaded the avs script into it, selected the "logo analysis" tool, set start/end markers for a set of frames that I thought would be good to analyze (~1500 frames). Then drew a rectangle around the logo with a few extra pixels for padding, set the threshold to 128 and started to analyze the logo. Saved the ldg file and loaded it into AviSynth+.



Not bad .... Here's the ldg file: test 1280x720-128.lgd

And script used was:

LSMASHVideoSource("899.mp4")
DelogoHD(logofile="test 1280x720-128.lgd")

thank you but when I run THE SCRIPT I get this error : System exception - Illegal Instruction

Didn't you already try using DelogoHD when you tried upscaling to 1440x1080?

[Flash_Bang]

When I tried it just played video with logo

My cpu does not support sse4.1 so, I used delogo instead of delogo hd and i got same results

I was wondering why it didn't work since you said you had tried it. Did you get the same results as the picture I posted?

You may want to look at different threads here on how to that. There are various options, for example you can use ffmpeg/x264 directly as they accept an avs script. Or you can use VirtualDub2 to export your video. But that is outside of the scope of this thread, if you wish you can open a thread in the newbies section or the AviSynth usage section and we'll help you out

That's nice lgd, bit better than what AvsInpaint produced with 2 frames (dark and white). Do you remember what range you set, because I can't produce an useful lgd? I don't see a way to set multiple ranges there too. It wasn't loading avs file (just hanged taking cpu).

I don't remember the exact range I used but I went by MeteorRain's suggestion: Blue sky and solid color wall are good background for making those samples.

I made another lgd using the range 985-12872 (which I believe was the range on the original ldg but not as long) and got the same results as first lgd. You mentioned that you used aviutl directly, when I tried that I also got bad results. Not sure If I did something wrong or what but when I loaded the avs script onto aviult I got the good results from the lgd.

Second lgd: test2 1280x720-30.lgd

Settings:


I read on a few sites that the threshold at default value (30) is a good value so I left it alone, on the first lgd I set it to 128.

It looks like those bad lgds are not because of loading mp4 directly nor range selection, there is some kind of bug in AviUtl/Logo analysis. It's unclear why it happens, but when it does then you can select different ranges, settings, area - resulting lgds always are not good. After AviUtl restart it usually starts producing good lgds.
Did you installed some filter for avs loading, I don't see anything for avs in the pack?

That threshold I imagine is max value between min-max luminance, or something similar, so you don't need to select the frame ranges manually. I think similar feature could be added to InpaintDelogo.

EDIT:

Found how to produce it: "Y" must be odd, if you set it to even then all good again.
Here how the bug looks (top right corner):

No, everything came in the pack that I linked to in post #21. I believe it uses L-SMASH Works File Reader to open an AviSynth script.

I did install an updated version of LogoScan but that was after I made the first successful lgd.

-----

One thing I wish DelogoHD had would be the ability to output just a black and white mask padded to the width and height of the input clip. DelogoHD seems to affect some areas just below below the logo. With a mask that can be easily fixed and even do some additional denoising just on the logo area. Although, there's already a script (LogoNR) that does denoising on the logo area by cropping, filtering and then overlaying the result onto the clip. Edit: Well scratch that idea, AddlogoHD can be used with the same lgd to add the logo onto a blankclip to create a logo mask. Cool stuff

You know I was actually thinking the same. With the bad lgd I tried moving the mask in DelogoHD +/- 1 pixel and it would always off. I just did not try to find out what caused it. Nice find VoodooFX. Maybe I will write a small tutorial on how to create an lgd file since it's very simple to do and produces very nice results.

What is content of your avs script?

It deblends that whole square area, not only logo.

Here InpaintDelogo for comparison:

InpaintDelogo( mask="d:\mask.bmp",
\ Automask=0, aMix=2, Loc="1124,24,-52,-636",
\ Mode="Deblend", Analyze=3, FrB=12369, FrW=8993, FrS=3,
\ Inflate=2, Deep=0, IntSpd=2, Interp=1, dPP=2)

Just the first frames I found, these are too bright and too dark frames I think, should be better with less bright/dark ones (mind FrS if you'll try other frames).

First run with Automask=1 to generate b/w mask, then set back to 0.
Set Interp and dPP to 0 to see pure deblending.

Just a source filter for FlashBang's video in post #20.

LSMASHVideoSource("899.mp4")

And it worked in aviutl. I did have to comment out the LoadPlugin call in the first line though because the video would not load in aviutl.

I might of been mistaken, with my original lgd I saw that it affected slightly other areas below the logo. But looking at it again with the updated lgd I can't really spot it anymore. I compared against:

src = LSMASHVideoSource("899.mp4")
delogo = DelogoHD(src, logofile="test2 1280x720-30.lgd")
mask = Blankclip(src, color_yuv=$000000).AddlogoHD(logofile="test2 1280x720-30.lgd").mt_binarize(1)
mt_merge(src, delogo, mask, u=3, v=3, luma=true)

But the masked delogo video and the plain delogo video look identical around the logo area.

Oh, that's why.

For your test you've used your second lgd, the first lgd was done with bad threshold, maybe you've seen that effect on the first one.

Btw, those "bad" lgds are actually good in AviUtl, but gets borked in DelogoHD.

Yes the threshold being set to 128 on the first lgd is what caused it.



Threshold parameter in LogoScan: Threshold value to determine if the background is a single color. The higher the value, the more lenient the judgment.

The "bad" lgds are also good in MakKi's original Delogo plugin for AviSynth. I also checked putin's Delogo/Delogomod from 2014 and they're are also good. So DelogoHD is the culprit.

Yes, I linked to it in post #31 ... it includes both ScanLogo and Delogo for aviutl but in English. An older version is already included in the aviutl English package.

A few tips.

1. Pick videos that have clean flat areas around logo positions.

2. Make sure you only include frames that have the logo. Don't include CMs that don't have logo on it.

3. Better use mod4 or at least mod2 (even numbers) for positions and sizes, for better compatibility.

4. Leave about 3 pixels around logo when choosing the boxed area.

5. Threshold, the lower the cleaner but you get fewer samples, the higher the worse but you get more samples. Pick wisely. For animes or clean source, 20 should be a good balanced number. For real life content, 30 is good. If the source has too few samples, increase to 40 or 50.

6. If you scanned a logo and would like to exhibit it on my website you can email to i(at)i.wtf and attach your lgd files.

This might be a long shot, but does anyone have a working .lgd for MeTV sources? I found an .svg (below), but haven't quite figured out how to transform one format to the other. Thank you!
