Who has removed TV logos from captured videos?
 
8O I need some simple instructions on removing logos from MPEG2 captures. I am using xlogo, as it runs with Avisynth 2.5x. I have read the instructions on doom, etc, but am still a bit confused. If anyone has had a successful experience with doing this, I would sincerely appreciate some advice.

I have figured out DeLogo for Virtualdub, but I use VirturalDub-MPEG2 and have no avi files. My captures are as MPEG2 and I use d2v files from DVD2AVI trimmed in VirtualDub-MPEG2. I don't know how to save MPEG2 files from VirtualDub without recompressing as AVI.

You can also use virtualdub plugins in Avisynth.
But ... you have to

1. ConverttoRGB32()
2 ..... VirtualdubPlugin Routine
3. ConvertbacktoYUY2() or ConverttoYV12 ... depends upon your capture colorspace and the following filters!

I'm now in my office so I can't give you a sample yet, but tonight Ill post an example line how to implementate for example Logoaway.vdf in Avisynth incl. importing right the determinet seetings via Vdub so u can use them in Avisynth. :wink:

Great! Please be very detailed, as it is pretty confusing to me.

Code:

##################### VirtualDub LogoAway #####################
#
ConvertToRGB32()
#
LoadVirtualdubPlugin("C:\Your Path to the Logoaway Plugin\logoaway.vdf","_VD_logoaway", 1)
_VD_logoaway( 2, 44695556, 2228259, 0, 128, 8, 0, 66051, 0, 1, "")
#
############ Change back to previous colorspace ####################
#
ConvertbackToYUY2()

As you can see you have to download using Google the Logoaway.vdf Plugin and install it into your Vdub Plugins Folder.

Open the Captured AVI in Vdub, choose Logoaway in the Filters and do your settings as mentioned in Logoaways readme doc!
In Vdub "safe processing settings" as .vcf, .... open the vcf using the EDITOR where you can find a filter line like this:
Code:

VirtualDub.video.filters.Clear();
VirtualDub.video.filters.Add("logoaway v3.01");
VirtualDub.video.filters.instance[0].Config( 2, 44695556, 2228259, 0, 128, 8, 0, 66051, 0, 1, "");

Copy the values in the "instance[0].Config" line and paste them into the "_VD_logoaway" line of your Avisynth Script right as shown above ...!

BUT ... You have to put all these lines shown above in the script BEFORE resizing!!!

This is one method to kill the logo by using the easy setup-window of logoaway in virtualdub, but on the other hand its not the best to use Vdubplugins in Avisynth cause of needed color conversation to RGB32() and back to YUY2() !

Hi @ll:
I used Xlogo and gave me good results (a bit slow). I also read about using virtualdub delogo, but never used it. It's true that virtualdub filters require first to convert to RGB, but Xlogo also converts to RGB internally and then back to YV12. I hope they will improve the filter in order to be used without internal colourspace conversions.
Have you tried last Mr Tibbs filter (NoLogo, I think).
But as you need some simple instructions, I will explain you the way Xlogo worked in my script,... as soon as I get home :roll:
Meanwhile, you can make the bitmaps. For a color opaque logo, you need a black and white bitmap (the logo in black), and remember to take note of the x,y coordenates (that must be even numbers), to make the bitmap dimensions even numbers, and to save it as a 24-bit bitmap.
