I just posted my LogoTools plugin. It replaces LogoBlend as well as adds a number of other helper filters.

New Filters:

NoLogo - replaces LogoBlend
NoLogoM - like NoLogo but with better control over the removal - great for problem logos.
AddLogo - add a logo
IfLogo - logo detection
IfNoLogo - logo overcorrection detection (what if I removed the logo when it wasn't there?)
LogoMask - mix two frames based using the logo as a mask.

You can get the filter at:

http://www.geocities.com/mrtibsvideo/Logotools.html

AddLogo ! Great ! A lot of people claimed for taht also.

Congratulation.

I admit that it seems stupid but perhaps someone may need it. I included it because the code was already there and one way to remove a logo is to cover it up with another logo.


Uses for AddLogo include:

1. Add the logo where it is missing to make removal easier.
2. Add a second logo and remove both for situations where multiple logos appear at different times.
3. Create a "inverted" logo and add it to the frame to help with removal.
4. Cover up a Kafka removal with a logo to hide the errors.

Thanks for these logo removal tools Mr Tibs im off to download them now.

One more filter added to the DLL:

NoLogoAuto - same as NoLogo with no fiddling - requires the logo to be on a completely black frame.

Example:

NoLogoAuto(clip,logoclip,framenumber)

What specifically replaces "clip"?
What specifically replaces "logoclip"?

I know these must seem like dumb questions.

I have a sample of 10 frames.
The name of the sample film is "tenframes.avi".
The 5th frame is white logo on black.


LoadPlugin("C:\aa\MPEG2Dec3.dll")
LoadPlugin("C:\aa\old\loadpluginex2.dll")
LoadPlugin("C:\aa\old\LogoTools.dll")
avisource("c:\aa\tenframes.avi")
#NoLogoAuto(clip,logoclip, logo frame number)

NoLogoAuto(clip,"C:\aa\tenframes.avi", 5)

I get TMPGEnc error: 'I don't know what "clip" means'

Clip is the default video clip.

I.E.


Personally, I usually trim my original video capture and make short video sample with the logo on a black frame then save it as a huffy clip like "abc_logo.avi". My logo script would look something like this:

I would then use Vdub to save that file as "abc_logo.avi".

Then to filter out the logo:

I generally, keep video sequences for each logo I encounter.

Given the sample code below, how would NoLogoAuto() fit in? My captures are MPEG2's with d2v from DVD2AVI.

MPEG2Source("C:\My Documents\noisy.d2v")
Trim(33333,44444)
Undot()
Limiter()
converttoYUY2(interlaced=true)
video = SeparateFields().BicubicResize(480, 240)
evenfield = SelectEven(video).TemporalSoften(1,5,8,5,2).peachs moother().Unfilter(60,0)
oddfield = SelectOdd(video).TemporalSoften(1,5,8,5,2).peachsm oother().Unfilter(60,0)
Interleave(evenfield,oddfield)
Weave()
Letterbox(16,16,16,16)
Limiter()

Here is the modifed script:
The line "logoclip=Trim(clip,100,101)" is to create a separate clip from the original source that contains the logo on a black frame (this assumes that the logo is at frame 100). When I call NoLogoAuto, the logo frame number is 1 since the logoclip is only 1 frame long.

You could try this, but I don't know if it will work:

My actual script is below. It does run, but does not remove logo. The logo is on a black frame #20070. I had to put "clip" in several statements [undot(clip), etc] to get it to run. I tried both NoLogoAuto statements and even included frame 20070 within clip itself.

clip=trim(clip,3067,20056)+Trim(clip,25940,49383)+ Trim(clip,20070,20071)

Undot(clip)
Limiter(clip)
#NoLogoAuto(clip,clip,20070)
NoLogoAuto(clip,logoclip,1)

Limiter(clip)

Your script will not only not remove the logo but would also not apply most of your filters. Here is what you script should look like:

Sorry, I go to link but dont see how to get Avisynth 2.5 version. I see it says to use LoadPluginEx.dll, but where is that.

I click on how to and it takes me to a page which says see zip file.

Does that mean the zip file for avisynth 2.0 file?

that means that there is no Avisynth 2.5 version. you have to use the 2.0 version for 2.5 through the plugin "LoadPluginEx.dll", which can be downloaded somewhere else.

Getting TMPGEnc error:

Evaluate: Unrecognized exception!
(H:\testtibb\testtibb16.AVS, line 17)

And a couple questions (please stay patient, I am learning and do appreciate your aid):

Is it possible to process in two steps? In other words, to produce a filtered mpg or m2v as I have been doing, then run again, without affecting compression, etc, and removing the logo in a second process.

I guess what I'm asking is whether you can process a previously encoded mpg and remove the logo without affecting anything else.

Or can you delogo process a capture without affecting the existing encoding, then encode with filters to produce the final mpg?

Well until now I didn't try my filtering routine in combination with MrTips Delogo routine ... so I can't give you a solution immideately.

But ...

Sometimes can be solved if you just restart your PC

I had these Problems too when Avisynth got "too hot" (sound stupid but I don't know how to explain using other words *g*) during much tryings and changings.

What happens when you load this last script in Vdub???
Also same Error?


MOMENT!! STOP now I see!

You only put the mpeg2source within a varaible "clip"... and this variable "clip" will only be called in the delogo routine!
So .... after this threre doesn't exist anymore a self based mpeg2source-line which provide the frames to the following filter routines!

Im thinking right !???
Maybe Im confused but this sounds logical ... I would like to attend, but at work (where I'm now) I'm working on a MAC

Hm...

Once NoLogo is called, it returns the filtered clip back to the default clip. Clearly, Undot and Limiter don't have trouble so I'm not sure why the problem.

Perhaps NoLogo isn't returning the clip properly.
You could try this:

Edit: I tested your script with an MJpeg source in Avisynth 2.0 and it worked quite well. (Nice script by the way.) I'll test in 2.5 later today.

The script is by Incredible. It is the only script I've found that will make a smooth copy of Futurama. There is a scene in the one I use for test that is a takeoff of twilight zone and has a digital clock moving on a black space background. With his script, the motion is perfect, with all others, there are various degrees of small motion jerks.

Also, I have been testing requant with a mpg from this script and same source. Requant is fine up to 82.5% compression, so you might want to experiment with it some. It's fast and simple to use.

Is there any way to delogo an encoded mpg without affecting the size, bitrates, etc? Like things I've encoded in the past and didn't keep the large capture files?

Really appreciate everything - NickSteel

[quote="MrTibs"]Hm...

Perhaps NoLogo isn't returning the clip properly.
You could try this:

Just tried this. Script ran, but logo was unaffected.

OK, now we are getting somewhere.

Change the frame number in NoLogoAuto to a negative. This will put NoLogoAuto into debug mode and show you where it thinks the logo is.

I didn't have the clip=NoLogoAuto(clip,logoclip,1) command in, only the Undot(clip) when I said the script ran without removing logo. When using both clip=NoLogoAuto(clip,logoclip,1) and Undot(clip),
