Is there any way to have s-video out on standard vcr

[dexy]

Here is some technical question. I have standard VCR with RF and composite out. Is there any way to connent wires inside in VCR on certain location to have s-video or component output. As you know, every VCR brings y/c information separatelly, so it is probably possible to do this.

I don't think it's possible.
If you want S-Video-output, get an S-VHS recorder, they usually have one (I never saw a normal VHS recorder with S-Video-out)

I dont know, I have never seen standard VHS recorder with s-video too, but I have seen them with component out (scart). Also I have some cable that connects scart to s-video. This cable dont have any adapter on it; wires directly connects scart and s-video. I dont know how and why, but it is. By the way, picture is trully poor, but this also can be affected by slim wires. My question is, is that cable good or not, couse if it is good that means that component output can be directly connected to s-video? I can only get some VCR with scart, but I dont think that I can find some s-vhs recorder right now.


Sorry for my lateness, my connection is really terrible right now.

Is this cable ok or not? are the wires directly connected (without any adapter) on cable that you are using.

Regular VHS is recored with COLOR under where SVHS is Color over meaning that the color signal is recoreded above the luminece Y.

So if your VHS machine has RGB out thru the scart connector and the YUV hasn't been mixed together, then you could encode out using those signals.

This can be done with several analog or digital encoder ICs. There maybe a box that takes RGB in and s-video out. However the recorder still can not play SVHS tapes.

I do not have s-vhs tapes. I want only to rip standard tapes, but without chroma artifacts! ;-)

Well, then I need some converter to convert RGB to s-video, and the cable is bad. I am wonderring if I can get good picture (without chroma noise) using good composite cable (which is about 1,2 m long)?

The cable is not going to solve the chroma nosie problem. I mention that it would not play S-VHS tape smiply to make a statment.

There is no way that your VCR can output virgon RGB from the tape, thats not the format but the signal may be more pure than the composite out. I have built many RBB to Pal & Ntsc encoders and most of the time the signal quality is better simply because you the builder are not restricted by goverment rules of signal balance and levels.

Building is not that hard, a good Phillips IC data sheet is all that you need. Infact I still have some chips is stock. These are the large pin type and are easy to work with.

With my JVC 9900 in has a three frame color digital filter which does the reduce the noice.

CNR plugin for VDdub is good but leaves chroma mouse tracks when large movement takes place. Don't know about the "Avisynth" CNR.

Think about what you recorded originally, RF or composite were originally mixed luma and color, which means there's no way to just separate them. What you need to be asking is for some filters that can help you instead. Even hardware boxes use these same filters.
I mean avisynth filters.

No.

@rfmmars

Yes, I know that, but I have bought better cable becouse I will use it with my VCR. Buying new VCR today is stupid couse VCRs are obsolate. Also I cannot lend it from my friend (who has VCR with scart) for every tape. So I decided to do this.

@jmac

Yes, now I must find some good filters. CNR is good, but I probably need some more.

@racer

Have you tried to do that, or you just know that?
