Blue Noise with JVC HR-S6600 - VHS upgrade advisable?

Hi,

I have been reading this website (and others) a lot and I think I got a decent workflow, thank you for the great information! :)

However I'm experiencing some (blue) noise and I think it is caused by the JVC HR-S6600.

Will a different/better S-VHS player show less noise (mainly the blue channel) or will it not get much better?

I have attached two examples and a short unedited recording (taken from JVC VHS-C EC30 SPRO with a VHS AD 25 adapter).

Thank you for reading. Other tips/information about my recording are also welcome. :)

Workflow:
1- JVC HR-S6600 (B.E.S.T. turned off, Picture Control on 'Edit')
2- SCART (with S-Video signal)
3- Panasonic DMR-EH55 (AV-NR turned off)
4- S-Video
5*- Hauppauge ImpactVCB-e PCI Express (Chip: CX23885-315Z) (Video levels lowered)
6- VirtualDub (Hauppauge WinTV 885 DirectShow, this is (5)) with Lagarith Lossless Compression

*I'm pretty sure the blue noise is not cause by the ImpactVCB-e because other TV recordings (from Panasonic) don't show this problem.

'Low' Blue noise in daylight scene: see images

'Extreme' blue noise in dark scenes: see images

use a good color denoiser like camcorder color denoise with a low value between 5-15 like this:

Code:

AVISource("schaap.avi")

assumetff()

ConverttoRGB32(matrix="rec601",interlaced=true)

separatefields()

LoadVirtualDubPlugin("C:\Program Files (x86)\virtualdubmod1.5\plugins\Camcorder_Color_Denoise_sse2.vdf", "CCD", 0)

CCD(10,1) #  0 to 100, default 30

weave()

converttoyv12(matrix="Rec601",interlaced=true)

Thank you for your quick reply.

The script you gave me works perfectly! :) So a better VHS is probably not needed.
What is the disadvantage of going above 15? Losing too much color?

Do you perhaps also know a way to remove a green line at the top? I attached a short .avi to show the problem.

Because I'm using the onboard soundcard the sound is slightly too late compared with the video (constant offset I think). Can this be fixed with avisynth?

Check this thread for your green bar: http://forum.videohelp.com/threads/3...ntal-color-bar

Thank you. I got the script in that thread working, however the green bar is not always there or has different thickness, so a static correction will look less appealing than the green bar.
