Hardware based Video Noise filter

[jfebus]

Hi All,

Is there a Hardware Based Video Noise Filter out there?

I got a Vitec DCM MPEG Capture Card and it's awesome, BUT it doesn't have a noise filter built in. I know that the noise filter built in TMPGENC is great, but I want to save all that time capturing directly to MPEG2.

I will like to get some hardware stuff I can connect between my VCR and my Capture Card.

Any ideas?

Regards,

Jose

What you want can be done with just two devices: a parametric EQ (equalkizer) and a dynamic compressor/expander.The para EQ will be used in a feedback path from the compressor, thus giving a dynamic noise reduction.I.e: with loud audio, no noise reduction and with low volumem the noise reduction increases.So the dynamic range will be preserved.I'm using Behringer Tube Ultra Q for para EQ and a Behringer Composer Pro for compressing.

Aaaaaaaaaa, he is talking video noise, not audio noise.

If you're going through coaxial cables, a video/electronics store in your area should have an inline noise filter. They cost about two or three bucks. I don't know how well they work, though.

Also, if you use Virtualdub to capture, there is a setting to filter noise. It will bump the CPU usage up about 10%, but makes a difference in the final result.

HI All,

I am using standard RCA video connections so I can't use the RF inline filters. I am capturing using the DCM software and I can;t use virtualdub to access the DCM card.

Will a SIMA SCC Video Color Corrector help me? Will buying a new vdr help me?

Thanks,

Jose

You are completely right.I should have learned to read a sentence completely.Anyway if someone needs Audio noise reduction....

[BJ_M]

hmm yes there are many .. like the snell and wilcox unit which is one of the best .. only ones i know about though are $5000- $25,000 , i'm sure there are others ..

Hi all!

Thanks for the help!

I just bought a JVC Professional SVHS with noise filter and video calibration! All the noise (snow) it's gone!

Jfebus,
Can you provide info on what type of unit you bought?(ex: model #,price,key features,etc.)
Can you provide a link where I can find out more about it?
I'm in the middle of a project which I have to convert a couple of VHS home movies into DVDs and some of these home movies have noise and might also need some color corrections.

Thanks

As I got a similar JVC VCR, I have a question: where does the noise filter come in?My has only a switchable TBC, no noise filter.

[jfebus]

Hi,

Mine has a Digital TBC/Noise Filter buttom in the front.

Regards,

[Dragonsf]

Is this a combination (switch activates both TBC and noise filter) or are this separate switches?

[jfebus]

It is a combination switch....

[Dragonsf]

Now I understand, in EU (at least in de) JVC doesn't sell VCRs with TBC+video noise filters.Just TBC.

[jfebus]

Hi,

I bought in jandr in us...

Regards,

[Dragonsf]

According to JVCnly sold in US and Jandr doesn't deliver outside US.
If I understand the manual correctly, this is a digital noise reduction.
Does it work for older tapes too? With my VCR, on older tapes, I even have to turn off TBC, because the picture is getting worse.
I'll check if I have this TBC/NR feature on my machine too (haven't noticed that before, but might be).

[jfebus]

Hi,

Maybe it''s just a Noise Reduction..but it works GREAT!!!! I am using it in tapes over 8 years old!

If you are outside US you can use a service like www.yupi.com that they give you an US address and then forward the packages to your final destination.

You can also use a Darim M Filter.

It's a PCI (or ISA) card, with a couple of filters and a TBC.

Glad the noise filter built in to the JVC helps, I have the same model and didn't find it good enough.

The M Filter can do wonders though about 2x$$.

What in the world is an ISA slot ?

System Requirements

* IBM PC/AT compatible computer with Intel Pentium 133 MHz or better CPU
* 24MB of system RAM. 64MB or more is recommended
* One empty 8- or 16-bit ISA slot (no IRQs or DMA are required!)
* Windows 98, NT 4.0 SP3 or later, 2000
* 5 MB of free hard disk space for basic software installation

Does this device use any SW for doing the job?
Because my PC will be occupied capturing the video at that time and cpu intensive SW will effect this.
The standalone version looks more usable anyway:

and is in a (somewhat more) comfortable price range than other filters.

ISA

ISA is an older conector like PCI.

All of the info is provided by the manufacture (the second link), and Visisble Light has a PDF available.

You can choose either ISA, or PCI when you order. The Pro version is PCI only.

It may not be what your looking for, it's intended for realtime mpeg capture cards, not software based ones. But the filtering is all hardware based, the chips on the card take care of this task. It does use a software control panel that allows you to dial in the settings. There is no interferance at all, think of this as an internal TBC.

--------------------------

The standalone does the same as the interal version. You're paying almost $300 more for Component (BNC) connections, as that is the only difference between the two.

[Dragonsf]

About ISA: this was a joke.
(all my current MoBos don't have ISA slots)
But I haven't seen a PCI spec on the given site!
Anyway:
I'm capturing from DV.So if I understood correctly:
You fed the analog video from VCR into the card, the signal will be digitized, filtered and converted back to analog.And the the signal is fed into (let's say) the HDB for second A/D conversion (this time to DV) and then captured into the PC.If the DSP (for Video) will not effect (influenze) the DV capturing process, this should work.
Any way to tap the digitized video in the filter card (just before D/A)?

[Dragonsf]

Just checked my VCR:it has this TBC/NR feature too.But I didn't notice any difference on video noise - using this feature.

[jfebus]

Maybe your VHS doesn't have as many noise as mines..

Are you satisfied with the performance of the VCR? Mine is only 1 week old....

Regards,

[Dragonsf]

Yes, I'm very satisfied.And maybe you're right:depends on the kind of noise, you're dealing with.I got very old tapes (20 years old), which perform quite well.I got some troublesome (with a lot of noise), but the noise was created by the VCR (which had a bad head at that time).This sort of noise can't be filtered good.I'm trying to get rid of these tapes (record the movies once again- with 80 % success now).
I'm very satisfied with my current VCR.I'm recording movies for permant tape store on chrome tapes using S-VHS ET.The one I want only temp. on tape (going to DVD afterwards), are recorded on S-VHS tapes.The dropped framerate on S-VHS tapes is much lower (1 per 5 min) than on regualr tapes (1 per 1 min).And you can adjust a lot of parameters.
BTW: I'm using a video amplifier between VCR and capture device: this straightens out any sync problems and noise in closed areas.Before I had this mosquito noise in dark areas, now I don't have them anymore:Black is still black and dark blue is still dark blue.This amp is from DataVideo and by accident removes MacroVision.
