Script to rip difference between 2 videos

[lindewell]

Hi, i want to rip harsubs from anime videos, most of the time you can find the raw of the video. So I had the idea to subtract the two videos so that it nullifies the background.

Here is the script I used:

# Change the following line to your source file; avoid spaces in file name
v1 = AviSource("[Ch-F]_Terra_e_-_Toward_The_Terra_08_[94911D39].avi",Audio=False)
v1=v1.Greyscale()
#v1=Crop(v1,0,324,0,-10)
v2 = AviSource("[S^M] TOWARD THE TERRA 08 RAW.avi",Audio=False)
v2=v2.Greyscale()
#v2=Crop(v2,0,324,0,-10)

return v1.subtract(v2)

And here is the result:

Input 1:

Input 2:

Output:

The background turns to grey but I still have problems with the subtitles because they are merged with the background.
Any idea how I could keepthe texts without having this problem?

I'm using subtract, I know there is also the Overlay filter but I'm a beginner. Should I use a noise filter?
I need advices thanks.

I forgot to mention this is not a dvdrip but fansubbed anime, most of them do hardsubs.

I take it you haven't read the forum rules (http://forum.doom9.org/forum-rules.htm) yet, especially rule 6? :rolleyes:

Yes, make yourself familiar with our rules and you'll fit in fine here. (The newbies announcement (http://forum.doom9.org/announcement.php?f=6) clarifies rule 6 somewhat. And regardless of your personal feelings about the legality or ethics of fansubs, the admins have heard them all and still find it in the board's interests to disallow them.)
