Hi

I need some help

I have a VCR tape that was filmed in 1988 using a HITACHI VK-C770 camera attached to Hitachi VT-7000E and Timer VT-TU70E (purchased in 1981) I had to use a external light source as the camera did not capture light well and it had to be hooked up to a TV to see what you were recording. The actual VHS footage is only 1 hour long and captured using PAN NVHS960B>>Svideo>>CAMCORDER>>iee1394>>PC>>WinDV

I have viewed the Raw DV on my Captured PC and its looks dark and there are chequered patterns in the bright areas, Ive posted 2 clips so that you can see what i mean

Ive installed AviSynth and Vdub, but no plugins as i dont know which ones i will need

I'm sure the 2 clips have other problems that im not aware off

Can the clip be restored in any way

Thanks

im assuming this is PAL from the use of the NV-HS960 deck
DV is actually acceptable in PAL land

what cam are you using as a DV converter?

Odd. The first clip was played with a quality Panasonic S-VHS VCR with TBC, using s-video ... yet had dot crawl. I can only remove some of it. And I'm not sure it actually dot crawl, because standard dot crawl noise removal methods have no effect. I tried several. Standard noise reduction (NR) methods were used in my sample clip.

I somewhat wonder if the DV converter caused the "dot crawl" error!

zack82-dotcrawl.jpg

It has dropouts.

And green chroma noise.
And chroma dropouts.
And just general analog grain noise.

Avisynth was first, then VirtualDub.

Code:
ffvideosource("C:\1988 one.avi")
ConvertToYV12
checkmate(thr=12, max=12, tthr2=10)
Deen() # remove edge noise
ConvertToYUY2
DePulse(h=100, l=1, d=15, debug=false)
DePulse(h=10, l=800, d=5, debug=false)
ChromaShift(C=-8, L=4) 
DeGrainMedian(limitY=15,limitUV=7,mode=0, norow=true)
ConvertToYUY2
- Checkmate (the dot crawl filter) had minimal effect, but a small improvement was there, so I left it.
- Deen knocked out some small edge noise.
- The two DePulse filters each attack different dropouts -- one black, one white.
- The chroma was offset. It's back where it belong now.

The degrain filter helped with general noise and some more dot crawl. The side effect is softening -- remove more noise, remove more detail. So it's about as best as can be done. You can, of course, try more tweaks.

VirtualDub is used for the masking, chroma noise removal, and more mild NR.

Code:
VirtualDub.audio.SetSource(1);
VirtualDub.audio.SetMode(0);
VirtualDub.audio.SetInterleave(1,500,1,0,0);
VirtualDub.audio.SetClipMode(1,1);
VirtualDub.audio.SetConversion(0,0,0,0,0);
VirtualDub.audio.SetVolume();
VirtualDub.audio.SetCompression();
VirtualDub.audio.EnableFilterGraph(0);
VirtualDub.video.SetInputFormat(11);
VirtualDub.video.SetOutputFormat(11);
VirtualDub.video.SetMode(3);
VirtualDub.video.SetSmartRendering(0);
VirtualDub.video.SetPreserveEmptyFrames(0);
VirtualDub.video.SetFrameRate2(0,0,1);
VirtualDub.video.SetIVTC(0, 0, 0, 0);
VirtualDub.video.SetCompression();
VirtualDub.video.filters.Clear();
VirtualDub.video.filters.Add("dynamic noise reduction (MMX)");
VirtualDub.video.filters.instance[0].Config (12);
VirtualDub.video.filters.Add("Camcorder color denoise 1.6 MT");
VirtualDub.video.filters.instance[1].Config(100,1);
VirtualDub.video.filters.Add("resize");
VirtualDub.video.filters.instance[2].SetClipping(17,10,10,18);
VirtualDub.video.filters.instance[2].Config(100,100,1,4,3,1,720,576,4,3,1,4,1,0x000000);
VirtualDub.audio.filters.Clear();
It too hard to tell from a small clip if the NR is set too high (default), or should be removed entirely. Keep that in mind. Use judgment and see how it looks. You never wanted to overfilter!

The second clip had chroma noise and mild grain. That could be entirely done in VirtualDub.

I don't usually go into this much detail for Free Members, but like I to show off my dropout removal method.

Wow

Thanks for your Help premiumcapture and lordsmurf

Those uploads are much much better,cleaner looking

is there a script command i can add to 1988two.avi that makes the video a bit brighter
or should i leave it as it is

I'm tempted to add spline36resize(352,576) should i or would that look bad on a 1080p display

After using zack81.avs, Do i then goto File>>Run Script and choose zack82-1.vcf, to use both scripts on this video



thanks again

You can play with HSV in Virtualdub or Gradian Curves in RGB. The funny thing with camcorders is that many try to adjust to light levels on their own, which can create video that requires different amounts of brightness correction, so take it piece by piece.

Video often appears lighter on TV. So if you make it look perfect on a non-calibrated professional monitor, it'll come out looking terrible when viewed on TV. Beware! This is a very common newbie mistake.

For those who use a tv as a monitor, this shouldnt be an issue. Computer screena also offer better color, so what you see may not be what you get in that sense either

Please attach images to the forum. http://www.digitalfaq.com/forum/news...ly-upload.html
All of the tinypic/etc images are broken and/or require unsafe JS for that site.

I'd love to help -- but you have to put the images here!

The jpegs are too big and I think the compression is making the text blurred out, try cropping out all the unnecessary space.

Open the two files with notepad (yes, notepad) and triple-check to see that you have all the filters on your computer. Once you are absolutely sure you have them, most likely its an issue of file location, but I am not good with avisynth so others might have better input.
