how to remove logo by avisynth scripts and filters?

[poluhale2]

hey guys.... i'm using megui. i want to remove logo from this video clip. can u pls give me sample script for removing logo?

Because it's opaque, there's no way to make it look 'good' afterwards. You'll frequently have a large and ugly blur. However, this is the script I used and maybe you can improve on it, with work. Be advised, though, just opening this script for an entire movie often takes longer than the length of the movie itself.

Crop(0,74,0,-72)
InpaintFunc(mask="logo2.bmp",loc="72,0,-564,-386",AR=4.0/3.0,mode="Inpaint",speed=10, ppmode=1,pp=70,radius=10.0,preblur=10.0)
AddBorders(0,74,0,72)

But I've never used MeGUI and have no idea how to edit the scripts it makes. Maybe make a lossless AVI in VDub first before then using that in MeGUI.

That really should not be necessary. If the OP is able to use MeGUI at all, I would be absolutely amazed if he could not figure out on his own how to edit a script in it. In my opinion it's a completely unintuitive program and I have never been able to get it to work without the AviSynth script it generates needing substantial changes to even start up. I suppose anything is possible, but I'd be really surprised if the OP hasn't already had to edit scripts in it.

Just one note - if you search on removing logos via AviSynth you may find a Russian website that claims that you can make logos completely disappear with one of their filters. You should understand that the screen shots they have are not honest and while their filter does work, it does NOT work as well as they claim it does. Even the very best attempts I've seen at removing a logo still have some small areas where you can tell that there was a logo at one time.

I had to edit an AviSynth script in MeGui, and nothing changed from the last job I ran it on except the source and destination files. It just refused to run on one line, claiming some error, so I deleted the line and Viola! Luckily it was something innocuous.

The script came from this http://www.spirton.com/convert-videos-to-60fps/ site, and I've been using this interpolation script for a year or two.

I chaulked it up to loose/sloppy code, and it still works, so no biggie.

If it's an opaque logo, I use the method outlined here:

thanks... but i don't want to use virtualdub.

See budwzr's link which shows you how to add functions to the Avisynth scripts MeGUI uses.

Then don't. You asked for a sample script and I gave you one.

All you'll do is make a fugly blob that's more distracting than the original logo.
Just leave it alone.

If it must go, just crop the whole video.

Just ignore Smurf, his religion prohibits using logo filters.

You can't just blindly use that script, unless the mask you're using is exactly the same as mine. If you make your own, then you figure out your own 'loc' settings. Anyway, if I still have the 'Logo2.bmp', I'll upload it for you.

Also, did you get the necessary AvsInpaint.dll (which is a 'C' plugin), the ExInpaint.dll, and the InpaintFunc.avs?

[manono]

now i'm got this error

I get that error when I comment out the AVSInPaint.dll. It probably has to be loaded in the script. I told you it's a 'C' plugin:

LoadCPlugin("C:\Path\To\AVSInPaint.dll")

Also, rather than trying to load the whole movie, I hope you're testing on a small part of it first, until you get a working script, either by using the sample or by trimming off a part of the movie for testing.

[manono]

Either load it as a 'C' plugin as in my example (and as I do it, assuming you have a reasonably up-to-date version of AviSynth installed), or load that AviSynth_C.dll" before you load the AvsInpaint.dll.

[manono]

Don't know. What version of AviSynth are you using? If you don't know, add 'Version' to a script and open it in VDub.

Load everything in the script:

LoadPlugin("D:\AviSynth Stuff\Dlls\DGDecode.dll")
LoadCPlugin("D:\AviSynth Stuff\Dlls\AVSInPaint.dll")
LoadPlugin("D:\AviSynth Stuff\Dlls\ExInpaint.dll")
Import("D:\AviSynth Stuff\plugins\INPaintFunc.avs")
MPEG2Source("E:\Test\Logo\test.d2v")
Crop(0,74,0,-72)
InpaintFunc(mask="logo2.bmp",loc="72,0,-564,-386",AR=4.0/3.0,mode="Inpaint",speed=10, ppmode=1,pp=70,radius=10.0,preblur=10.0)
AddBorders(0,74,0,72)

If by "religion" you mean "not blind as ****"...

... then yes, I guess my religion is to not use de-logo filters.

Sorry you can't work out how to use a fairly simple filter.
