Messing Around with RGB Scart, Component Video (Part 2)

[TheBladeJunker]

Your main Genesis unit is looking good, nice placement of ports. I tried 1080p but I don't think it looked much better than 720p plus my streaming buffer couldn't keep up.

The component looks good to me but its a hard thing to demonstrate in a video. One thing that makes it hard is that analog video output standards sort of gradually climb in clarity but will always be soft. You'll have to invite some subscribers over to see it in person. ^_^

Awesome work as always.:D

One more thing I atched anoher video of a guy showing odfd scart to yuv compnent as you have done, and he indicated that some models of USA SNES do not have rgb output in them, so do your research for the snes you have.

[duhmez]

Hey do u have a normal interlaced CRT that has component inputs? That would get u the absolute best results, would look amazing. And as usual, the bigger the better! I think the biggest that exists is 36 inch, and 36 inch crt with component classic consles would rock. I hope to have that setup one day. In addition, it owuld be excellent to get yourself a scart splitter so you could have everything wired up for scart, with a single component output.

It looks good in 1080p, but for people with a screen size below 32" it doesn't really make a difference. I recommend you post in 720p to save file size and upload time. but interesting video :)

[thomas3120]

@07SHeP Ahh cool, did not know that :) So there's no improvement at all on let's say 21-27" PC monitors? Thanks for the comment and info.

[tom611]

@thomas3120 For something like this, where you might pause it and get closer to look at the difference, 1080P would likely help for 21-27" monitors. Plus, there's no guarantee that people aren't watching on 32"+ monitors (my brother uses one on his PC).

In general though, I don't bother with higher than 720P on my 22", the bump in res doesn't make a huge difference even at a couple of feet away.

[07SHeP]

@thomas3120 Yeah just though id let you know because the file size on 1080p is much higher. and it takes much longer to upload. 720p to me looks the same as 1080p I have a 15" display. But really good quality nonetheless! :)

[duhmez]

I am sad because I have a projector with a slot for scart, but unfortunately it is just a piece of plastic covering the spot for scart. Same mold obviously for canada vs Euro models.

[28steryan]

Nice man.

I love my bog-standard little CRT with a Scart.

[daafies2]

another cool vid. why scart tho?

[thomas3120]

@daafies2 Thanks David :) Something I wish we had here in the US. It's a way to use RGB on televisions, mostly in Europe, originated in France (a type of A/V connection). It also carries audio (stereo), composite and I believe S-video. But yeah, RGB is the way to go. Next best thing I guess would be component (almost like RGB). I've always wondered about HDMI though...hmm, will have to do some reading on it.

@thomas3120 scart rgb is not hd, component goes to 1080p and hdmi is the best at the moment.hdmi-component-rgb scart-composite

[shock25sr]

Can hardly begin to grasp all the stuff you mentioned and what you are aiming for :D!

But it never ceases to amaze me how skilled you are!

Cool vid!

Cheers! :D!

[thomas3120]

@shock25sr Hey Shock! Good to hear from you. Saw your vid earlier :)

And thanks :D

[shock25sr]

@thomas3120 I noticed you thumbed it up mate and it put a smile on my face knowing i wasn`t forgotten :D!

I`ll be posting coments on your older vids but i just wanna say i followed your osciliscope refurbish series and was amazed at how much you devoted yourself to that thing!!I`de do the exact same knowing twas my dads and all!Turned out as good as new mate!And that AC-DC test run at the end... :D!

Cheers thomas!

And thanks for th suport :)!

[atarileaf]

Very interesting Thomas. You know I can't wait to see the Coco 3 results but it looks very promising so far :)

[thomas3120]

@atarileaf I thought you'd like it J :) If you have a chance, try and pick up one of those converters...really amazing. I'll let you know/do a video on the results of the CoCo3 in Component :)

[tom611]

Curious, have you tried this with optical lightgun games on any of the consoles with the CRT TV? I'm wondering if the video conversion messes with the signal timings enough to make an optical gun not work.

As far as the mods, why not put the caps in the adapter box, since you need them for practically all consoles? For Playstation, a Guncon adapter would be easier to hack as it has all 15 pins already installed for the pass-through. Also, C-Sync should work in place of C-Video.

[thomas3120]

@tom611 On the Sony CRT TV that I got? ...yes, I tried the Menacer light gun and works well. It does have some lag, but reading up on it and some reviews, it seems to be normal?

Each one is a bit different, well the caps are just coupling caps and some consoles require 75 ohm resistors. And just in case there's a console or computer that requires different components, it would be easier just to have it in the cable.

I'd love to make something like the Wii-motes, but centering may be a prob.

[tom611]

@thomas3120 Wii-mote like replacement for retro consoles would be pretty impressive. For a white-screen fill type game, you could monitor the RGB lines for when all go white for a screen fill, then use the sync signal to count out the scan position, when it matches the position of the gun based on IR, push down a hit.

The Menacer and guns like it would be a lot harder, as they measure phosphor decay after the scanning beam passes to determine the gun position constantly.

[thomas3120]

@tom611 Ahh, also on the Tandy CoCo3, on the RGB out, it has H. Sync. and V. Sync. both are positive syncs. Before the converter, I had to install a Sync. seperator (LM1881) to get a C. Sync. to make it work. The scart converter just needs comp. video, so it's a matter of hooking just one wire up to the RGB port.

[segajcharrua]

good video thomas, yes for the sync many consoles uses c sync for the rgb, but it isnt necessary because you can get a better sync, like the french consoles they all use true sync

in case of the genesis because you use rgb you get a jailbar efect across the screen because of the C sync and it can be very noticeable on lcds i already mention it on one of your videos on how you can fix it.

[thomas3120]

@segajcharrua Thanks :) Yeah, there's H sync., V sync., C sync., sync. on green, sync. on red, sync on blue (last two are not used much, if at all). However, the scart converter I have uses composite video as a sync (along with R, G, B and GND).

No jailbar, even on the LCD TV I tried :) All the lines you see is unfortunately from the video camera recording the screens (especially the crt). In person it looks fantastic :)

[segajcharrua]

@thomas3120 yeah it varies by lcd to lcd but most of times it has that efect , its just the way it its on the video encoder. but if you don´t see nothing like that, then never mind what i said, but i think on a pc lcd you got that shimmering effect because of the c sync most likely.

[thomas3120]

@segajcharrua Ahh yeah :) that was on the Samsung Syncmaster 204 LCD monitor. Someone told me the monitor was trying to de-interlace the interlaced picture (ugh..can't remember the exact wording). But yeah, that's what was causing the shimmer on the PC LCD monitor. Although, I tried the SNES on it and it was a lot better for some reason.

[Padoca85]

Nice! i use an arcade converter that upscale the image from and RGB/Component input to VGA for my systems, im currently adding an amp circuit to n64 to give me a better picture. oh, and the lines on the crt are scan lines and a suposedy to be there, lots f people try to archive this effect on lcd screen for a more retro look^^

[thomas3120]

@Padoca85 Very cool, since VGA is pretty much RGB.  I was wondering about the N64 since I made the SNES cable...if it would be the same or different.

Yeah, know about the scanlines but the lines there were all from the video camera capturing video from the screen...

[Padoca85]

@thomas3120 Its the same pinout since youre your using the composite video as a sync. But on the N64 it does not have the RGB on the conector, you have to jumper them from the grafx processor, and most of the times build an amp circuit to boost the signal. Unfortunally not all the N64 can be modded to RGB. Just google mmmonkey N64 RGB, and you find the whole guide to it :)

[thomas3120]

@Padoca85 Ahh, excellent! will def. check it out, thanks :)

[Bylga]

Another great video!

[thomas3120]

@Bylga Thanks Bylga, yeah very happy with the results :)

[Polaventris]

That looks really good! Thanks for the demo and the link!

[thomas3120]

@Polaventris Thanks Juho :) & np

[darrenwalshsock]

It looks like it was well worth the effort mate :)

[thomas3120]

@darrenwalshsock Thanks Darren! Yeah definitely over here since we don't have scart :)
