Questions that do not deserve a thread

[Ikaruga11]

Is S-Video part of the RGB or YPbPr color space?

It's YIQ.

Since GB/GBC/GBA games were developed with RGB in mind, wouldn't it be better to use the GameCube's RGB instead of it's native YCbCr for the correct colorspace on GB/GBC/GBA games?

YCbCr is just a mean to represent RGB.

Thanks Extrems.

Never heard of YIQ before. So are RGB and YIQ generated/converted from the internal YCbCr framebuffer?

[Extrems]

Correct.

[Xer Xian]

I know next to nothing about different color spaces, granted, but I really don't think you need to worry about that. Yeah S-video has a channel reserved for luminance as it has YPbPr (and unlike RGB) but it remains inferior to these in terms of color accuracy. Also, if I remember correctly people were having problems getting GBI to work with S-video, don't know if that was sorted out with updates..

Since we're at it about cables, has anyone noticed retrogamingcables.co.uk is now offering GC and PS1/2 cables with built-in sync stripper for clean sync? I have an official SCART RGB cable for PS1 and I've been happy with it for years but now I'm tempted to buy one of these. Should I go for it or I'm good with what I have?

Really? That's awesome. If the official SCART RGB cable for PS1 outputs clean sync, I would just stick with that.

What does the official RGB SCART cable for GameCube output? Composite, Luma or Clean sync?

[Xer Xian]

It has sync on composite - luma is not viable since PAL GCs do not output S-video, and clean sync is out of discussion too I'm afraid. Sync on composite was the standard for pretty much every consumer level product bar maybe something by Sony which were supporters of sync on green.
I'm pretty sure that the RGB cable for PS1/2 has sync on composite too. But unlike GC, PS1/2 are known for having a good quality RGB output - hence why I'm asking if it's worth looking for a custom cable.

That sucks :/

Sync on composite RGB is still better than S-Video on the GameCube though, right?

I've heard that CSync is possible with the analog GCVideo mod and official component cables modded for RGB. Is that correct?

[Xer Xian]

Yeah I would say that RGB is better than S-video no matter what.
Sorry I have no idea about your other question - modding a GC component cable for RGB is something that has never crossed my mind, as it would lose the ability to carry a 480p signal as far as I know.

Yes, it has more bandwidth for the signal.

So not even a custom or modded RGB SCART cable can output CSync through the Analog AV Out?

Will modding the GameCube component cables output CSync on their own, or do I also need the GCVideo Lite (analog version) to output CSync over modded component cables?

I was replying to your question about RGBS compared to S-video, sorry for not making that clearer. I have no clue on the GC component or GCVideo as I have neither.

I'm looking for a HDMI -> USB3 capture card that allows mixing of analogue audio with the HDMI audio. Simply make gameplay videos with added voice over. Does such an item exisit, or do I need to look for capture card and video editing software?

[Lord of Pirates]

I guess it depends on what you want to use the 50pro for. 240p recognition was added at some point, but I can't see you using that feature and I doubt that the JVC fw is based on the earliest DVDO fw, since it was released so much later on.

My guess after looking at the Anchor Bay site on Internet Archive is that it's likely based on 1.03. I have the OSD timeout options from 1.03 but I don't have WUXGA or WSXGA+ from 1.04. A press release from JVC mentions April of '08 as the availability date and FW1.04 released in early April. Possibly something between the two but, only Ken or someone else from DVDO could confirm that.

It's only going to be handling DVDs (HDMI 480i) and BDs (likely just passthrough) so the lack of 240p recognition isn't a big deal but it would've been nice to have the latest FW regardless.

On another note, what sort of fans does the VP50 Pro take? I'm pretty sure the two in this one are dead but it could just be due to the insufficient power supply I've tested with.

most of the modern cards do that. Elgato, Avermedia etc. It's a key selling point for many streamers.

Thanks, do people use the bundled software or is there a good free/low cost alternative compatible with most cards?

[Fudoh]

Elgato's included software is perfectly fine. OBS would be your first choice as an alternative.

[Einzelherz]

I'll probably regret asking, but why can't you just use your component cables?

[Ikaruga11]

Nothing to regret.

I could use my component cables, but weren't GameBoy, GameBoy Color and GameBoy Advance games developed with RGB? If that's the case, then wouldn't YPbPr be the incorrect color space? I was wondering if RGB-modded component cables would be better for GB/GBC/GBA games than unmodded component cables.

[bobrocks95]

Surely the Gameboy Player is shoving the data into the Gamecube's internal YCbCr framebuffer anyway. Colorspace conversions are supposed to be lossless if you do them correctly anyway???

[Extrems]

*facepalm*

There are rounding errors that accumulate, and chroma down/upsampling start acting as a low-pass filter.

[Einzelherz]

The amount of internal "error" you think is happening, GL, is going to be compensated by your display not being 100% perfect anyway.

But what color space is that data encoded for? Or is there none?

*facepalm*

Could you elaborate

Yeah, since analog isn't a lossless format, degradation from conversions is a thing.

The amount of internal "error" you think is happening, GL, is going to be compensated by your display not being 100% perfect anyway.

You mean the "error" being the alledged incorrect colorspace used? You're right. I don't think CRTs can ever be 100% perfect, and there will be some discrepencies between two models calibrated the same.

[Einzelherz]

There are discrepancies in the SAME set. LCD, Plasma, OLED, CRT, it doesn't mattter. There's no such thing as perfect color reproduction.

[Ikaruga11]

Yeah, that's what I meant to say. And of course no display will never have 100% accurate color reproduction. But ideally speaking, I thought RGB (even converted from YCbCr, would be more accurate for GB, GBC,GBA games)

So I'm guessing it's better to just use YPbPr than RGB due to information loss/errors/compression from the color space conversion?

[Einzelherz]

Just to put this in perspective for *you*, you're concerning yourself with color accuracy on a portable system that has four shades of green or grey.

I think there are slightly more important things to get hung up on.

I just want to know what color space was used for the GBC and GBA.

[Extrems]

If you're talking RGB color space, it doesn't correspond to any standard.

The standard version of GBI performs color adaption for a Rec. 709 monitor with 2.2 gamma.

[Unseen]

Why 709? It's only used for HDTV, SDTV (480i) uses Rec. 601 primaries and as far as I can tell the same is true for EDTV (480p).

[Xer Xian]

GeneraLight, relax man

I would bet my GC component cable (bought at retarded ebay prices) that there's no way in hell you could tell apart RGB from Component while playing gameboy games (maybe through side-by-side comparison you could spot incredibly small differences). If you're still looking for answers though, you can have a look here for GBA specs, and here's a user on assembler explaining how to get RGBs from an NTSC GC (and also how to get 480p over RGB - I was wrong in my earlier post).

Of course you don't need to sacrifice an official cable for PAL units as you can take RGB from the analog port and add a sync stripper to the cable.

Doesn't 601 exist inside of 709? And we're talking about a 32k color pallette, at best, which is largely why my eyes have nearly rolled off.
