VHS Cleanup, What can i do?

[jagabo]

Ive played with alittle now... What do you think now?

That's an improvement but now you have problems at the opposite end. Notice how the details in the dark areas of the woman's hair have become totally black in themaster1's sample images. You're definitely on the right track.

Sanlyn is right that the "ultimate" fix is to get a time base corrector (either in an s-vhs deck or dvd recorder) but there is a lot you can do short of spending money on that. And if this is a third generation recording a TBC may not help much.

I did a little noise filtering and quick color adjustments. It still has a long way to go but this is starting to get in the right ballpark.

[themaster1]

here is the best i came up with so far:
scene1 http://imageupload.org/en/file/210620/scene1.jpg.html
scene2 http://imageupload.org/en/file/210621/scene2.jpg.html

I've used msu color enhancement (settings: 3,2,9,autolevels) and colormill mainly. I'm not a fan of this msu filter but i must admit it does the magic here.

[Asesinato]

The Master.. That look realy alot better... What setting do you change in colormill to get that?

[themaster1]

Download the .rar archive it contain the vcf (file>load processing...)
You must re enter the values for msuce (3;2,6,autolevels) (6 appears to be good enough for me)
install the filter camcorder... if you don't have it

[Asesinato]

Wow that looks awesome...

Is that it ? Are there more that can be done with other filter, are is it as clean as its going to get?

[Asesinato]

I just tried to apply som filters i have try before with a good result, but they made the video look worse Realy weird

[themaster1]

hmm yeah try to add the msu old color filter at the end,default settings

[Asesinato]

Wow yyeah that did alot to... Have tried that on the old rip and didnt think much off it, but here it dos magic....

[Asesinato]

This look already much better then i ever hope for, you guys are magic

Ive added a clip from another part of the vid so you can se that with filters to

[Asesinato]

Ups forgot the file

[themaster1]

there is much work on the table still: deblocking,denoising,removing dropouts, fix the levels by scene also perhaps etc.. but i'll let others contribute a little

[Asesinato]

Ive made a avs file that contains this fucktion ;

function RemoveSpots(clip input, bool "_grey", int "repmode")
{
_grey=default(_grey, false)
repmode=default(repmode, 16)
clmode=17
clensed=Clense(input, grey=_grey, cache=4)
sbegin = ForwardClense(input, grey=_grey, cache=-1)
send = BackwardClense(input, grey=_grey, cache=-1)
alt=Repair(SCSelect(input, sbegin, send, clensed, debug=true), input, mode=repmode, modeU = _grey ? -1 : repmode )
restore=Repair(clensed, input, mode=repmode, modeU = _grey ? -1 : repmode)
corrected=RestoreMotionBlocks(clensed, restore, neighbour=input, alternative=alt, gmthreshold=70, dist=1, dmode=2, debug=false, noise=10, noisy=12, grey=_grey)
return corrected
}

To help with dropout ...
Havent done anything like that before, just read in here from other post about dropouts...

And i virtualdub i added same filtering after master suggestions... ive added my listning for you all to see here under....

Anyone have some ideers?

[Asesinato]

( the avs file i open in virtualdub now has this in it :

LoadPlugin("C:\Program Files (x86)\AviSynth 2.5\plugins\RemoveDirt.dll")
LoadPlugin("C:\Program Files (x86)\AviSynth 2.5\plugins\removegrain.dll")

Import("C:\Program Files (x86)\AviSynth 2.5\plugins\RemoveDirt.avs")
DirectShowSource("C:\Users\Jytte Rødgaard\Desktop\elmebakken.mpg")
ConvertToYV12()
RemoveSpots()


)

[Asesinato]

So please post your ideers.... Im very very new at this so any help you guys can give me is much appressiatet

[Asesinato]

Wooops forgot the filter file

[Asesinato]

You must re enter the values for msuce (3;2,6,autolevels)

[jagabo]

Import RemoveSpots.AVS too.

[Asesinato]

I just copy that script from another thread... How dó i put that into it???

[Asesinato]

Anyone knows how to remove the flicking of the picture if possible???
You. Can see what i mean in the second clip i uploaded

[jagabo]

I'm guessing you mean the frames were sync was lost. You can try using motion interpolated frame replacement (mvtools required):

function RX(clip Source, int N, int X)
{
# N is number of the 1st frame in Source that needs replacing. 
# X is total number of frames to replace
#e.g. RX(101, 5) would replace 101,102,103,104,105 , by using 100 and 106 as reference points for mflowfps interpolation
         
start=Source.trim(N-1,-1) #one good frame before, used for interpolation reference point
end=Source.trim(N+X,-1) #one good frame after, used for interpolation reference point
         
start+end
AssumeFPS(1) #temporarily FPS=1 to use mflowfps
          
super = MSuper()
backward_vec = MAnalyse(super, isb = true)
forward_vec = MAnalyse(super, isb = false)
MFlowFps(super, backward_vec, forward_vec, blend=false, num=X+1, den=1) #num=X+1
AssumeFPS(FrameRate(Source)) #return back to normal source framerate for joining
Trim(1, framecount-1) #trim ends, leaving replacement frames
          
Source.trim(0,-N) ++ last ++ Source.trim(N+X+1,0)
}

Mpeg2Source("Untitled(1).d2v", CPU=2, Info=3) 
Yadif(order=1, mode=1)
Trim(0,450)
RX(13,1)
RX(17,2)
RX(20,1)
RX(51,3)
RX(55,2)
RX(66,1)
RX(176,2)
RX(183,3)
RX(191,3)
RX(195,6)
RX(202,11)
RX(276,4)
RX(399,3)
RX(417,1)
RX(432,1)

This works well for some shots (stills, simple motions, panning), not so well with others. You can see it screws up around frames 204 to 215.

I just copy that script from another thread... How dó i put that into it???

You can include the entire RemoveSpots function in your script, or import the AVS file from wherever you saved it.

function RemoveSpots(clip input, bool "_grey", int "repmode") 
{
 _grey=default(_grey, false)
 repmode=default(repmode, 16)
 clmode=17
 clensed=Clense(input, grey=_grey, cache=4)
 sbegin = ForwardClense(input, grey=_grey, cache=-1)
 send = BackwardClense(input, grey=_grey, cache=-1)
 alt=Repair(SCSelect(input, sbegin, send, clensed, debug=true), input, mode=repmode, modeU = _grey ? -1 : repmode ) 
restore=Repair(clensed, input, mode=repmode, modeU = _grey ? -1 : repmode)
 corrected=RestoreMotionBlocks(clensed, restore, neighbour=input,  alternative=alt, gmthreshold=70, dist=1, dmode=2, debug=false, noise=10,  noisy=12, grey=_grey)
 return corrected
 } 

LoadPlugin("C:\Program Files (x86)\AviSynth 2.5\plugins\RemoveDirt.dll")
LoadPlugin("C:\Program Files (x86)\AviSynth 2.5\plugins\removegrain.dll")
Import("C:\Program Files (x86)\AviSynth 2.5\plugins\RemoveDirt.avs") 

DirectShowSource("C:\Users\Jytte Rødgaard\Desktop\elmebakken.mpg") 
ConvertToYV12()
RemoveSpots()

Or:

LoadPlugin("C:\Program Files (x86)\AviSynth 2.5\plugins\RemoveDirt.dll")
LoadPlugin("C:\Program Files (x86)\AviSynth 2.5\plugins\removegrain.dll")
Import("C:\Program Files (x86)\AviSynth 2.5\plugins\RemoveDirt.avs") 
Import("C:\Program Files (x86)\AviSynth 2.5\plugins\RemoveSpots.avs") 

DirectShowSource("C:\Users\Jytte Rødgaard\Desktop\elmebakken.mpg") 
ConvertToYV12()
RemoveSpots()

By the way, I highly recommend you use DgIndex and Mpeg2Source() instead of DirectShowSource. The latter isn't frame accurate and can screw things up.

[themaster1]

I've got new settings which i believe improve the picture
Picture of previous/current settings respectively

I've worked more with the histogram this time, far from perfection though

You must remove the Auto levels option for msu old color

The sync errors I corrected with RX() may be better corrected by a second capture. You may find that different captures have problems at different frames. Then you can piece together multiple caps. Or you may find a different VCR does better than your current one. And as was mentioned before, a time base corrector may help.

Comets and playback noise can be reduced with multiple caps and a median filter.

The first post in the latter thread has the original video you can compare too.

[mammo1789]

The guys that answer you here are pretty knowledgeable people. I will just suggest as many to start from the root capturing better. You can also use VirtualVCR instead of VirtualDub ( i think it will support you card hauppage pvr 500 this one right ? )and capture in huffyuv ( or other lossless capturing codec like lagarith) that way your are very close to the source and no color conversation ( which can loose some details which are there) I guess you can also lower the sharpens on the picture it looks over sharped or I am tired and sleepy and don't see well .
I like the master try especially the last one.
As long as tbc is concern if you don't have vcr or dvd recorder ( as pass trough ) with tbc and don't want to spend any money, you can try some software version tries at doom9.org the guys there ( jmac is member also here )in recent times had very very good progress, which may help you with yours case.

[jagabo]

Yes, going with raw video capture rather than MPEG will get you better results. You'll be working with very large files though. HuffYUV at standard definition runs about 30 GB/hr.

Just for fun, I fixed up the second shot with RX().

jagabo I like how you never miss to mention that it uses a lot of space But i guess in these times 1-2 tb hdd is not so uncommon for regular PC users let alone video hobbyist and lagarith uses even less ( I always keep around 300 gb free.)

Just for fun, I fixed up the second shot with RX().

Well done I like to see the result when you became serious ( if this is just for fun)

[Asesinato]

Jagabo how dó i use those ohter things instead off directsourceshow???

[Asesinato]

Master that look realy GOOD ... Putting in the charges now

[Asesinato]

Jagabo the rx function looks realy good, how dó i implement it to my avs? What dó i need to change? And dó i need a dll for it?

[themaster1]

I got the perfect script for your source, previously discussed here (post #4): https://forum.videohelp.com/threads/343296-Transfer-of-real-bad-tape-to-pc-and-restore

I'm running it now, the previews frames look very good to me
