Ypbpr to vga transcoder suggestions

[TheRetroCarrot]

Anybody have suggestions for a ypbpr to vga transcoder? I got a Behar Garo Lite recently and have issues with image instability. The image with multiple systems flickers up and down by about a half cm with a 480p input signal. I don't have this issue if I use my gbsc for these systems but I'd rather not do any image processing for 480p as it's outputting to an EDTV crt.

Thanks.

I assume you meant to say "component to RGBHV".

This is the unit you want:

I had a bad experience with BeharBros and I noticed others on this forum have also been disappointed. So, rather or not you want to shop at BeharBros is entirely up to you. I'm sure they have other customers that are satisfied. I recommend the Retrotink Comp2RGB, because I know it's well engineered and the creator stands behind the products.

I unfortunately already purchased the Beharbros box, but it simply isn't performing as it should so not much option other than to purchase something else.

Doesn't the retrotink only output RGBs and not RGBHV? I'm honestly clueless about sync signals, being in NA I've always run everything off component and never really had to worry about it, but from what I understand they're not interchangeable.

Does anyone have personal experience with the JS box? That was actually the one I'm primarily looking at right now.

[SavagePencil]

Yeah, not sure why he's recommending a YPbPr to RGBS, when what you're asking for is RGBHV. And going Component -> OSSC/RT5X -> VGA is also a bit of overkill.

[orange808]

Youre right. My apologies, I have an Extron RGB in the chain that handles sync for me. Everything gets converted to RGBHV when I route it through the Extron RGB.

My setup is overkill. However, that's necessary if you want it right.

There are community SCART to RGBHV boxes and cables out there that you can purchase. I never tried one, but that's a viable option. Using Mike Chi's transcoder is worth the effort, because you can buy it brand new, it's actually designed by a real engineer that knows what he's doing, and he stands behind his products.

Alternately, some people can simply use a sync processor to break out horizontal and vertical sync and manually set the display (or a video processor in the chain) to expect ypbpr/yuv color space.

[TheRetroCarrot]

I might actually end up just running it all through the GBS-C. I cannot detect any degradation in image quality of latency, and it's nice it gives me geometry options and presets. The green push these have seems to only occur when outputting higher resolutions.

If anyone is interested here is my beautiful Garo Lite disassembled.

Can't say I'm impressed. Also the image instability is caused by a broken toggle switch between RGBS and RGBHV it seems, I noticed the image would lose sync the moment I touched it at all, then I toggled it and the plastic just disintegrated. I bridged the toggle to RGBHV with solder just to see and it seems to work fine now.

Think I'm going to see if they'll take this thing back. I'm so sick and tired of ordering things for a niche market and finding quality control just doesn't exist. I understand if there are bugs or firmware issues or unexpected issues with a design, but to ship a product covered in dried up solder paste...

This is the best choice imo. I tried a few others and they all had various issues but the 9A65 worked great.

I agree – they're unobtanium though. Literally took me 3+ years of eBay daily alerts to get my 2nd backup 9A65. Sure, might have missed one at some point if I didn't check my phone early enough or whatnot (and/or didn't want to pay like $250+ for one...), but still extremely hard to get and not really a viable option nowadays unfortunately. I would go with one of the modern options at this point.

Beharbros lack of quality is pretty infamous around here. The full version of the Garo was pretty terrible too. Incorrect sync combiner, incorrectly buffered video lines, short-to-ground scanline generator... Had to do an RGB bypass mod pulling sync from luma input and adding a video amp for buffering to get half decent results out of it. And by half decent I mean "working at all".

I thought that was the case, which is why I conditioned the suggestion. I believe it's also the case with the inverse (9A60). It took me a while to find the latter.

My experience with their first DC VGA box was poor, I ignored their products after that. The cable to the system was too rigid and audio eventually cut out. Replaced it with a VGA cable and had no problems since. I can live with s-video for the handful of titles without VGA support.

[TheRetroCarrot]

They refunded the transcoder and said to just keep it. The product QC might be awful, but customer support has been pretty good from my interactions. I'd be skeptical to order another product from them but I'm still appreciative this wasn't a hassle to get a resolution for.

On another note I did some extensive testing of the GBSC with all my systems, and so long as I'm outputting 480p, it seems like a perfect option. Being able to fine tune the image dimensions sure is nice on a widescreen CRT. For anything above 480p I just got the Extron DSC 301 HD which I'm absolutely in love with, so thanks to whomever recommended that on this forum!

Which GBSC model did you get?

The Hanzo? Bad news to me, then, I've just installed a brand new one. Did you plug and unplug it quite often, perhaps? Which is a good quality VGA DC cable you can still get these days (preferably with fake scanlines switch)?

[TheRetroCarrot]

One from aliexpress, bitfunx. I didn't do a ton of research prior, was cheap enough it was worth the chance. Seems fine, wi-fi disconnected once but seems like everyone has those issues. The OLED display on it is busted but I won't ever be using that, I'm sure I can get a partial refund anyways as it's aliexpress.

It does have a huge green push on higher resolutions, same one I've seen in all the video demos of the product. At 480p though this doesn't seem to happen.

The 9A62 is an earlier model that also works great for 480p. Used it to play Skyward Sword on a PC CRT and it was glorious.

Doesn't the retrotink only output RGBs and not RGBHV?

Every PC CRT I've used accepts either RGBS or RGBHV. So you actually could just use a typical transcoder with SCART.

On another note I did some extensive testing of the GBSC with all my systems, and so long as I'm outputting 480p, it seems like a perfect option.

I'd love to do a side-by-side with a analog converter one day. Because I have to imagine there is some horizontal digital sampling artifacts from the GBS-C. And doesn't it add a frame of lag too

It could but I can't detect any artifacts. I'm only using it for 6th gen and up systems on a Loewe 480p/1080i EDTV, I really can't detect a frame of lag in these more "modern" games. If I was using it for platformers and shooters I might be able to tell but for this it's worth it just for the image controls..

I believe it was from the seller mentioned in this thread:

It was years ago and they don't seem to be active anymore.

Seems there's one up on ebay from Belgium .

Wow, had no idea they became that rare. Back when I got mine they were still a few on ebay, but I guess might have been 5+ years ago.

Your go-to YUV to VGA transcoder these days should the linuxbot one: https://www.ebay.com/itm/174151197806

He's cycling through the versions and this particular is out of stock right now, but if you can usually pick one up every few weeks or so....

I've seen a few posts on r/crtgaming where people had chroma issues with his stuff. Like pink and yellow hues on white lettering.

Thought I can't remember if those were YPbPr>RGB or RGB>YPbPr. And those posts also seem to be vastly outnumbered by the people who seem to have a flawless experience. So I'm not sure exactly what's going on there.
