x-logo in VirtualDub -- multiple in/out points?

[StrobeLightEpileptic]

I'm trying a logo removal filter in virtualdub. The x-logo filter. I'm really amazed at the results, although this is a simple white transparent logo.

The problem is the logo appears over multiple frame sequences. A few seconds a fifth of the way through the film and then a few seconds a third of the way, again at the mid point, etc.

But the x-logo config panel doesn't have an option for multiple in/out points. Just one in point/ one out point.

Is there a way around this?

I'd use avisynth if I could find a tut on a script for it.

[jagabo]

Add more than one instance of the filter?

[StrobeLightEpileptic]

Thanks for the suggestion, but I can't get that one to work. I open multiple instances of the filter and do the settings, but virtualdub won't let me run them.

So, now I'm looking into an avisynth script, but the only examples I've found use the trim function. Like this:

-----------------
clip=AVISource("pb_221.avi",false)

clip.Trim(0,19) ++\
clip.Trim(20,0).xlogo("logo221_x_540_y_300_2.bmp", X=540, Y=300, alpha=0)
-----------------

I, don't know. Maybe I'm reading this wrong. Do I have it right that the first trim segments frames 0-19 without applying a filter? and then the second trim is applying the filter to frames 20 till the end. But it adds the two segments back together? Is that what it's doing?

So, if I had a 90 minute video I'd use something like:

----------------------
clip.Trim(0,12776) ++\
clip.Trim(12777,13798).xlogo("logo221_x_540_y_300_ 2.bmp", X=540, Y=300, alpha=0) ++\
clip.Trim(13799,48419) ++\
clip.Trim(48420,49445).xlogo("logo221_x_540_y_300_ 2.bmp", X=540, Y=300, alpha=0) ++\
.
.
.
---------------------

All the way till the end of the movie?

Yes.

All the way till the end of the movie?

Yes.

[Gavino]

So, if I had a 90 minute video I'd use something like:
----------------------
clip.Trim(0,12776) ++\
clip.Trim(12777,13798).xlogo("logo221_x_540_y_300_ 2.bmp", X=540, Y=300, alpha=0) ++\
clip.Trim(13799,48419) ++\
clip.Trim(48420,49445).xlogo("logo221_x_540_y_300_ 2.bmp", X=540, Y=300, alpha=0) ++\
.
---------------------
All the way till the end of the movie?

Yes, that will work.
If you have a lot of different sections, you might find it easier to use the ReplaceFramesSimple function:

clip.ReplaceFramesSimple(clip.xlogo("logo221_x_540_y_300_2.bmp", X=540, Y=300, alpha=0), \
  mappings = "[12777 13798] [48420 49445] ... ")

The function is part of the RemapFrames plugin which you can get from here.

If not using ReplaceFramesSimple, it would still be better to rewrite as

clip2 = clip.xlogo("logo221_x_540_y_300_2.bmp", X=540, Y=300, alpha=0)
clip.Trim(0,12776) ++\
clip2.Trim(12777,13798) ++\
clip.Trim(13799,48419) ++\
clip2.Trim(48420,49445) ++\
...

[StrobeLightEpileptic]

Okay. Well, I'm using this script:

AVISource=("F:\clipfolder\clip.avi")
Trim(0,12776) +\
Trim(12777,13798).xlogo("C:\bg2_x_489_y-426_0.bmp",X=489,y=426,alpha=20) +\
Trim(13799,48419) +\
Trim(48420,49445).xlogo("C:\bg2_x_489_y-426_0.bmp",X=489,y=426,alpha=20) +\
Trim(49446,74999) +\
Trim(75000,76021).xlogo("C:\bg2_x_489_y-426_0.bmp",X=489,y=426,alpha=20) +\
Trim(76022,103692) +\
Trim(103693,104714).xlogo("C:\bg2_x_489_y-426_0.bmp",X=489,y=426,alpha=20) +\
Trim(104715,128876) +\
Trim(128877,129899).xlogo("C:\bg2_x_489_y-426_0.bmp",X=489,y=426,alpha=20) +\
Trim(129900,154800) +\
Trim(154801,155822).xlogo("C:\bg2_x_489_y-426_0.bmp",X=489,y=426,alpha=20) +\
Trim(155823,165476) +\
Trim(165477,166207).xlogo("C:\bg2_x_489_y-426_0.bmp",X=489,y=426,alpha=20) +\
Trim(166208,0)

But I get an error saying that there is an Invalid Argument to the Trim function in the last line.

Gavino: I already had this script written out before I saw your post. I might give that a try, but I'd like to know what is wrong with my last line.

[manono]

But I get an error saying that there is an Invalid Argument to the Trim function in the last line.

Add another '+\ ' to that last line? I'm just guessing because I do my filtering-different-sections-differently differently. Either try that or try adding the real last frame number, rather than using '0'. Gavino will know.

I should have mentioned that I played with the script multiple times. I had already tried your suggestions. The program gave me an error on the "+\" for the last line.

I also tried giving it the last actual frame number.

Thanks for the suggestions though. I should have mentioned that earlier.

[Gavino]

AVISource=("F:\clipfolder\clip.avi")

That's your error right there. Remove the '='.

[manono]

Good eyes. I completely missed that. I can blame it on the error message which isn't always very helpful and sometimes (as in this case) downright misleading.

[Gavino]

In this case, the error message can easily throw you off the scent, since it seems to point to the wrong place.
But AVISource=("F:\clipfolder\clip.avi") is a valid statement (assigning a string to the variable AVISource) so Avisynth cannot know that you meant something else.

The result is that all the Trim's are seen as invalid because no input clip has been defined. However, it gets reported as being on the last line since the whole series of Trims is just one statement continued over many lines.

Knowing that "Invalid arguments" often comes from an undefined input clip led me to look at the previous line where the real error was.

I don't do "script".

Okay. Well, I'm using this script:

AVISource=("F:\clipfolder\clip.avi")
Trim(0,12776) +

I use ReplaceFramesSimple as well, and it really does simplify, as you only have to write out the filter once, and you only have to specify the ranges it applies to, the rest will be the unfiltered video.

AVISource("F:\clipfolder\clip.avi")
src = last
filtered = xlogo("C:\bg2_x_489_y-426_0.bmp",X=489,y=426,alpha=20)
ReplaceFramesSimple(src, filtered, mappings= \
"[12777	13798]
 [48420	49445]
 [75000	76021]
 [103693	104714]
 [128877	129899]
 [154801	155822]
 [165477	166207]")

NB: You can't use "0" for the last frame in this.

I use AvsP to step through a video, and use its bookmark (control-B) to mark the transitions, then save these to a file, paste them into a template.

I also always put the video, the image file and the script in the same folder, then I don't need to specify full paths.
A different folder for each project, which I can then archive away as a unit.

AVISource=("F:\clipfolder\clip.avi")

That's your error right there. Remove the '='.

Hats off to you. A slap in the head for me.

So, I went back to the code. After I posted last night I decided to try the ReplaceFramesSimple. Of course, when it came to the AVISource line, I just copied and pasted from the other script. So, not surprisingly, I got the same error with ReplaceFramesSimple.

So, when I went back I just decided to use the ReplaceFramesSimple because it is a lot less tedious. But what happens is VirtualDub crashes. Whenever I try to scrub the timeline while the script is loaded it crashes. An access violation. So, I tried to go ahead and save the AVI anyway. And it crashed right at the first frame that needed X-logo.

So, I went back to my other script and fixed it. But, it crashes the exact same way; with an access violation. The error message reads:


"out of bounds memory access (access violation) occurred in VirtualDub... reading address 00000008"

Sometimes the address was 00000010, but the thing is it crashes at the first frame the filter is applied to.

So, this is a pain. I checked to see that the film itself ran okay. No problem there. I can scrub the entire length of the film. Back and forth. No problem.

Last night when the scripts wouldn't work, I tried DeLogo. But the preliminary results didn't look so great.

So, tonight I'll probably look for another logo removal filter, I think there's another one, just can't remember the name.

But, X-logo gives me great results. At least it looks good on the previews I've looked at.

I do have a crash dump from VirtualDub. I don't know if anyone can make sense of it or not. I can't. But, I'll post it just in case someone can. This dump was with the Trim script.

NB: You can't use "0" for the last frame in this.

Thanks for that info. I did use the last frame number in the ReplaceFramesSimple script tonight.

I use AvsP to step through a video, and use its bookmark (control-B) to mark the transitions, then save these to a file, paste them into a template.

I also always put the video, the image file and the script in the same folder, then I don't need to specify full paths.
A different folder for each project, which I can then archive away as a unit.

Good ideas. I'll have to start practicing these. AvsP, I downloaded that once. But I didn't have time to work through it to understand it. Interesting program though.

I don't do "script".

Well. What can I say? You can't argue with success.

I have x-logo working in VD now and it's being applied over multiple instances. From what I can see in VD it's looking pretty good. Just a tiny bit of blur.

I don't know why, but I just didn't take your post seriously. And I only clicked on the YouTube link after about the third time I saw your post. I guess I just thought you were being sarcastic.

Anyway, Thanks for that. I'll have to look at that guy's website.

...although this is a simple white transparent logo.

Something like LogoTools usually works better than XLogo on see-through logos. With luck you can get rid of them entirely with no blur. It kind of depends on the logo.

You're very welcome. I thought you were dead-set on using script or I would have made my point a bit better...SORRY.

Well, now I'm wondering about that. I noticed as the xlogo filter was being applied that there was a slight blur to the picture overall. I think this is probably because I had interpolation set fully.

But, yeah there is also a small smeared area that shows up. It's visibility depends on the colors it overlays.

This logo is just lettering. Almost opaque in some parts and more transparent in other parts.

I'll look into LogoTools and see what that's about.

Thanks.

No need to be sorry. I'm pretty much for whatever works.

That's an interesting feature in VD I would never have known about.

Looking at other YouTube videos, I saw this one:

http://www.youtube.com/watch?v=96Vm78ig8Og

Here, he is using Adobe Premiere and applying a filter called Region Remove Video Filter.

The only filter by that name that I can find is a virtual dub filter.

Is it possible to use a virtual dub filter in Adobe Premiere?
