S-Video problem

[poutipouticat]

Hello, I am currently recording directly from my Nintendo 64 to my DVD recorder but I'm having some issues. I'm trying to get better quality by using a s-video cable.

Composite :

S-Video :

If you watch these videos in full screen, you'll notice that the second one (svideo.mp4) is far more pixelated. Apparently, this kind of artifacting is known as "dot crawling", and can be solved by using component or s-video instead of composite. The thing is... the problem only occurs when I'm using a s-video cable, everything is fine with composite. I'd like to know what I can do to solve this problem. And no, the s-video cable and video game system aren't defective, the problem is coming from my DVD recorder. Thanks in advance

Your DVD recorder isn't using a 3D comb filter on the s-video input, only on the composite input. Which makes sense since the s-video input shouldn't need it. But some devices create their s-video output from composite with a simple luma/chroma splitter that gives this type of dot crawl artifacts.

It's possible to remove dot crawl artifacts with software filters. VirtualDub's "DotCrawl Comb Filter", for example. You need to use the filter before resizing the frame.

Holy! That blows my mind and fills me with rage.

S-Video is WORSE on the N64? Makes me feel dumb for picking up a couple Monster S-Video Cables for Nintendo system (I haven't hooked them up yet). However, they were only $9.99 a piece

[jagabo]

I'm only going on what the OP said and the samples he posted. I don't now for a fact that the N64 converts composite to s-video with a cheap splitter. You should verify for yourself.

[DeXeSs]

Holy beans I just watched those vids. The S-Vid looks like rear! This is a catastrophe. My confidence is compromised.

Must research...

I guess based on very few facts is this only affects US N64 which sucks because I'm in North America. Heh

Um...All opinions exist here:

I'll just have to try it I guess.

THIS SUCKS!

This needs to be confirmed on another Nintendo 64. Jagabo is probably right. Best way to know is to test.
http://en.wikipedia.org/wiki/Nintendo_64#Video

Keep in mind that at that time (~1996) it was common for native composite Laserdisc players to construct S-Video from composite and the results were worse than composite tied to a premium comb filter (e.g. Sony XBR). Ideally, S-Video would be constructed from an RGB -> YUV -> Y/C transcode.

Thanks edDV. As soon as I'm back in Ontario, I'm head to my local Princess Auto to pick up a set of Monster Nintendo Composite Cables.

More RAGE!

Potential that it has to do with the cable?:

Use cheap cables for test. Monster cables won't help. The critical components are your HDTV comb filter and upscaler.

[vhelp]

I have the same problem with my old Nintendo -- dot crawl hell. I gave up on trying. Some things just weren't ment to be captured. These games were low resolutions to begin with. And, interlace makes it really bad.. it was in my experience. I was testing my Mario game back then.

More speak of the cable being the factor!

[edDV]

Comb filter is more likely for dot crawl, then deinterlacer, then scaler.

Play N64 games on your computer with an emulator like Project64. Much better graphics.

[DeXeSs]

I hope I don't get nailed for saying this but the shuttle PC I have hooked up to my folks 42" Aquos has every single cartridge ROM (except N64) installed onto it. (Connected with DVI) The quality is perfect.

I have an adapter that allows me to use a Playstation 2 Controller connected to USB wtih basicly 0 response time or at least it's unnoticeable.

It's the sweetest thing ever. I guess I could get the GoodN64 pack but I'd like to use the N64 controller. There must be some N64 to USB adapters though so maybe that is worth investing in.

Here's a puzzler:
NES Resolution 320 x 240i - Composite
SNES Resolution 320 x 240i - S-Video
N64 Resolution 320 x 240p - S-Video

Correct?

[jagabo]

Many years ago I bought a USB adapter that lets me hook an N64 or PS2 controller to the computer.

Any video signal that goes through a composite or s-video cable is interlaced. Both fields can be from the same frame though. So a game can generate 320x240 60 fields per second, or 320x240 30 frames per second. In the first case you will see 60 different pictures every second, in the second you will see only 30 different pictures per second (you see each frame twice).

[DeXeSs]

Right I should have been more explicit with what I was trying to convey.

I understand about interlaced/progressive.

I'm just interested in knowing what is the source on the cartridge. I guess cartidge is all progressive but the system is only capable of outputting interlaced whether by composite only or s-video.

I mean the NES had the RCA standard on the side. Why didn't every system just adopt that damnit.

They're no longer made.

[DeXeSs]

Jag, does your device work very well?

Response time is good?

[jagabo]

It's been quite a while since I used it but I don't remember any lag.

[DeXeSs]

Sweet. I'll pick one up. Thanks.

[DeXeSs]

SPAM!

There is nothing on that website about Nintendo 64. I will never buy from your crap site.

EDIT: Some doofus was advertising in the post inbetween my above post and this one but now it is gone.

[Jeroen1000]

Sorry for kicking this one up but...
I've got the netting/pixelation/masking/dot crawl issue using S-video also. Using composite the image is just blurry but without pixelation.

According to my VP the N64 was outputting 720 x 288 . As far as I know the N64 normally does not do that res...
Are there any confirmed cables to work? They sell one on store.nintendo.com for $15,00
