need help on removing green bar on top of a vhs video

[lansing]

There's a stationary green bar sitting on top of each frame of the video, I tried to remove it using the overlay function with different color adjusting filters, the best I can get is through coloryuv, but it's still visible, is there a better filter to do this?




sample is here:
http://www.mediafire.com/?hed3y7eg7pkeed2

o=AVISource("top green bar.avi")

AVISource("top green bar.avi").crop(0,4,-6,-468)
ovrlay = ColorYUV(gain_u=0, gain_v=53)

Overlay(o, ovrlay, x=0, y=4, opacity=1.0, mode="blend")

You can always crop it! Then resize if necessary. With that terrible video, it wouldn't look much worse. You have head-switching noise that needs to be cropped off the bottom anyway, so why not just do both?

Or maybe you can try something like BorderControl():

i don't want to crop it out because it still has details in it unlike the bottom

Here's a suggestion for a similar issue by jmac698 at digitalfaq.com forums, adjust as needed:

#Fix Sony 9000 Digital8 video
#A Script which fixes a problem where the top 6 lines of video have a green color
#Version 0.1 by jmac698  Dec/10
dir="G:\project001a\vcr comparison\"
imagesource(dir+"sony9000.jpg")#change this to: 
#avisource(dir+"yourvideo.avi")
pal=1#set to 0 for NTSC (obviously would apply to an equivalent NTSC hi8 deck)
goodline=13#increase this until the color is fixed, refers to the cropped coordinates
newwidth=720#The final width of the new video
newheight=(pal==1)?576:480#The final height of the new video
#This script is not completely general, generally only even numbers are supported
left=4#adjust these to closely crop your video
right=9
top=0
bot=7
Crop(left, top, -right , -bot)#Crop your video
addborders((newwidth-last.width)/2,(newheight-last.height)/2,(newwidth-last.width)/2,(newheight-last.height)/2)#Re-Centre your video
converttoyuy2
badcolor=last.vtoy#This is where the green line comes from
fillcolor=badcolor.crop(0,goodline,0,-(newheight-goodline-2)).pointresize(newwidth/2,goodline)
fixcolor=stackvertical(fillcolor,badcolor.crop(0,goodline,0,0))
ytouv(last.utoy,fixcolor,last)

Didée gave you the solution last time
# Move the chroma Up:
crop(0,0,0,-6).pointresize(width,height,0,0,width,height).mergeluma(last)
pointresize(width,height,0,6,width,height).mergeluma(last)

But it's not perfect with that crappy video once it is deinterlaced with nnedi3 i think i know why only U or V is concerned with the chroma misplacement, let's wait for Didée

that one doesn't work, it shifted the entire luma upward, making lots of ringing in all other areas.

thanks for this script, there still exhibit some light green and yellow after, so added camcorder color denoise on the top part and it works out pretty well.

LoadVirtualdubPlugin("VirtualDub-1.10.2\plugins\ccd_sse2.vdf", "CCD", 1)

AVISource("top green bar.avi")
assumetff()

nnedi3(field=-2)

pal=0 #set to 0 for NTSC (obviously would apply to an equivalent NTSC hi8 deck)
goodline=16#increase this until the color is fixed, refers to the cropped coordinates
newwidth=720#The final width of the new video
newheight=(pal==1)?576:480#The final height of the new video

#This script is not completely general, generally only even numbers are supported

converttoyuy2
badcolor=last.vtoy#This is where the green line comes from
fillcolor=badcolor.crop(0,goodline,0,-(newheight-goodline-2)).pointresize(newwidth/2,goodline)
fixcolor=stackvertical(fillcolor,badcolor.crop(0,goodline,0,0))
ytouv(last.utoy,fixcolor,last)

# add ccd on top part
ConvertToRGB32

temp = last
top = temp.CCD(100,1).crop(0,0,0,-(newheight-goodline))
bottom = temp.crop(0,goodline,0,0)
StackVertical(top, bottom)

ConvertToYV12(chromaresample="point") # convert back to yv12

Hmm, my scripts do get around.. glad it worked

Hello,
how can I adapt this to a right vertical green line?

[LemMotlow]

I already did that with chuibbyrain2 in the script in a previous thread. https://forum.doom9.org/showpost.php...58&postcount=2. Here's the part that cleaned it up:

# ------------ chubbyrain2 - interlaced, clean up border stain ----
separatefields()
a=last
 
a
chubbyrain2()
SmoothTweak(Hue2=7)
crop(690,0,0,0,true)
b=last
overlay(a,b,x=690)
weave()

Adding CamcorderColorDenoisie later in the script finished the job:

LoadVirtualDubplugin("drive:\path\VirtualDub\plugins\ccd.vdf","CamcorderColorDenoise",1)
ConvertToRGB32(interlaced=false,matrix="Rec601")
CamCorderColorDenoise(32,1)

Sorry to didn't take notice.

Hello,
Is there any x64 alternative to CCD?

I'm trying to adapt this part to vertical to see the results but
without any success for no.

converttoyuy2
badcolor=last.vtoy#This is where the green line comes from
fillcolor=badcolor.crop(0,goodline,0,-(newheight-goodline-2)).pointresize(newwidth/2,goodline)
fixcolor=stackvertical(fillcolor,badcolor.crop(0,goodline,0,0))
ytouv(last.utoy,fixcolor,last)


Tried to install everything in 32bit but how can I force AVS+ to install 32bit instead of X64?

BTW thanks for helping, I really like the output of your script.

Guess you'll have to wait for 300-plus Avisynth and VirtualDub filters to get re-engineered into 64-bit versions. Sorry to say, it's not likely to happen. I guess that's why so many people still use 32-bit, even with 64-bit OS's.
