    That shifting of lines when downscaling 480p to 240p is to preserve the 60fps. So you are witnessing how a 240p 60fps video signal works, shifting the odd and even fields for each video frame.

    Hey, this video is incredible and I want to thank you for a couple things: First, now I will be putting extra pineapple on any pizza I see. Second, the Enzo Amore reference was 🤌 callback to the earlier joke about Italians.
    BUT most of all, having all this Corio information in one place is incredibly valuable. I've got a languishing homemade arcade cab project with a consumer Trinitron with component in. And I'm planning to run a PC to it. I'm using a Titan X to try to keep the whole chain analog. I tried to use a GBS-C for the downscaling but it was too flaky. I've got a 750 waiting for me when I get back home to finally try to finish it up, and again, so happy for your coverage here. The other info on these is a little scattered and that shmups thread now has like 69,000 posts and the search isn't great.

      Thanks heaps for the compliment, I say pineapple as much as you want! The shmups post is great and like any forum is hard to navigate and find updated info apart from the first page and whatever hits google will highlight, so happy to pitch in with the collaboration. If a PC is the only video source in the cab then you may have a better time with CRT emudriver as someone else mentioned, but if you have other HD sources then the Corio is excellent.

    Thanks for the video, paisano. Very informative and interesting to watch. Do you plan to, or already have the RetroTINK 5X? I'm wondering if there's any lag there from 720p. I'm also wondering how will the Pixel FX one handle downscaling. Like you, I've become more interested in downscaling when it comes to those devices. And lol at the aspect ratio police, they are tough.

    • @MarcoRetro316
      @MarcoRetro316  Год назад +1

      The aspect ratio and resolution police are on the prowl lol. I don’t plan on getting the Tink 5x but have watched RetroBobarino’s review which he showed only 3ms lag 720p to 240p! However… it’s so fast because it’s purely line dropping, making text and graphics a little jarring unless the game uses 2D pixel art. Whereas the Corio averages 720p lines on the bottom 2/3rds of the screen which preserve some detail but makes 2D art slightly blurry, pick your poison I guess. I’ve got a Dexx addon for the DE-10 on the way which will downscale 720p and 480p to 240p/480i so I’ll see if it behaves like the Tink5x. I’m also curious to know all the ins and outs about the Pixel FX Morph downscaling

    Hey man, I know you're in a PAL country but I'm wondering if you can maybe help me figure out what scaler I should buy for my NTSC set.
    I have a beautiful 4:3 NTSC 32" JVC D-Series AC-32D201 from August 2000 that outputs an astonishing 450 TV Lines using your Mario warp pipe calculation. This TV has component input for up to 480i and can handle excellent 240p via RGB SCART connection to Component adapter. (Sadly, like virtually all NTSC sets this JVC lacks SCART input directly).
    I'd like to get a HDMI to Component downscaler that can go from 1080p to 240p, and ideally 480i and 480p as well though the real important output for me is 240p. I'm not especially bothered by aspect ratio but bonus points if that can be adjusted as well.
    I see the adapter you have as a complex web of connections in this video. Anything a little more basic, that goes from 1080 to 240p simply from HDMI to YPbPr.
    Currently, I am using a cheap HDMI to S-Video adapter for my Switch and that looks surprisinly good. I'm just sure that it's possible to get just that little bit extra goodness from Component downscaling to 240p over S-Video, hopefully.

    • @MarcoRetro316
      @MarcoRetro316  Год назад

      I’d recommend a TVOne Corio in your scenario. In hindsight the multiple connectors I used wasn’t the best option although I’m not compelled enough to change it. You can feed HDMI straight to DVI and the Corio 750 has an audio passthrough option through DVI. I haven’t tried it myself but if audio doesn’t work then you could always fall back on the analogue VGA route. DVDO scalers can apparently downscale 1080p as well but I haven’t tried it out yet. Otherwise to date, these 2 are the only ones to downscale 1080p to 240p, without using some other scaler to drop to 480p to then feed into a GBSC

      @SatoshiMatrix1 Год назад

      @@MarcoRetro316 Oh right, I forgot the Switch can be put into 480p mode. Okay. So assuming that, I would then need to drop HDMI 480p to Component 240p. That. What's the best device? A spcific name would be very useful. Thanks.

    • @MarcoRetro316
      @MarcoRetro316  Год назад

      Unfortunately the HDMI to component scaler I’ve featured in the ‘gaming on a widescreen CRT’ video is old and I haven’t been able to find a link to it but that essentially up and downscales so I used to output 1080p to 480p into a GBS, then if I wanted 480i I would set the HDMI to component to 480i and GBS to pass-through. This Amazon Au listing describes very similar in and out resolutions, up and down scaling to my device but can’t guarantee it’ll work the same or if it’s internally identical. I’m yet to test lag and scaling but it worked fairly well with very rare occasions of screen tear.

    Firstly, thanks for your content. There is no way that I could perform these comparisons, so this is extremely helpful.
    And if I could be so bold as to ask one more question - I have a 27" Sony with very low hours (I purchased new 25 years ago) that's waiting for an RGB mod.
    But I'm also considering a 31" Sanyo with Component Video, which would deliver a 27" horizontal picture - even in 16:9.
    However, based on the Service Manual, the Component-In is in 480i. What will happen if I feed that input a 249 signal? Would it automatically still upscale to 480i ?
    Sorry, I am new to this whole CRT scene, so I am just starting to figure this out. Thanks for your help and patience.

    • @MarcoRetro316
      @MarcoRetro316  Год назад

      Thanks! Unless the TV states 100/120Hz or 'HD' then it's safe to assume the Sanyo is 15KHz, so it should display 240p properly

  • @shodan6401
    @shodan6401 Год назад

    I forgot to mention, and this is pretty important (aside from typing 249 instead of 240p previously), I am in the U.S. on the NTSC standard. AND, I am only outputting from a PC to any CRT.
    I may even be able to create a custom resolution on my graphics card profiles. Any proprietary content would come from emulation (the HORROR!!). So I don't have the hurdles of sending different devices using different resolutions to my TV.
    But I'm still concerned that a Component input that creates a 480i resolution will upscale my 240p signal to 480i on the 31" Sanyo.
    Still watching your series to learn - thanks. But it dawned on me that maybe I can downscale via my graphics card before the frames are generated, since I don't have any consoles. I only have to worry about 480i upscaling on the Sanyo, not the Sony.
    And if I'm playing a modern title, I can switch the Sanyo to 16:9, assuming that the aspect ratio is handled by the tube, not by digital processing.
    If the TV is changing to 16:9 via digital processing, I THINK that there is a setting on the MiSTer FPGA to output in 16:9, so I might be able to sidestep that issue if it exists.
    Does any of this sound reasonable, or do I sound like an illiterate, pretending to read what's on the page?

    • @MarcoRetro316
      @MarcoRetro316  Год назад

      Makes perfect sense. You just need to be sure the Sanyo isn't an HDTV which can be done by using the 240p test suite and using the dropped shadow video test to see if it displays correctly. If you have a lightgun then this is another way to test. I haven't played with pc CRTEmudriver or equivalent but I plan to after I have finished with the downscaling series. Only some Mister FPGA cores can output 16:9 via the core menu. PS1 I know definitely can for 3D games. If the Sanyo is 100% an analog, SD TV then a 16:9 mode won't cause any processing, artefacts or lag

    • @MarcoRetro316
      @MarcoRetro316  3 месяца назад +1

      @Gabriel-xi3sm yes that’s fine because the interlaced option will be set to ‘on’. As for why NTSC is 29.97 and not a perfect 30, the scaler is meant for video timings and modern displays expect 59.94Hz (effectively 60Hz). But you’d be hard pressed to notice a single errant frame stutter every so often if the source ran at a perfect 60Hz, I didn’t see any in my testing. But it shouldn’t be a problem to slightly alter the NTSC vertical refresh to a whole number, though I’d leave it as is.

    Just install CRT Emudriver on a cheap PC. Don't fool with all this blurry, laggy Corio stuff.
    All these pixel art games: TMNT, Bloodstained, Sonic Mania, are available on PC, and you can play them at native resolution, no scaling needed. Which of course means no lag either.
    All you have to do is figure out the native resolution for each game, then make that custom resolution in Emudriver
    Bonus for Sonic Mania is on PC it has a config file tweak that switches to 4:3 output, 320x240. The other games you have to set your CRT's raster to 16:9 (if you don't have a 16:9 CRT)

    • @MarcoRetro316

      GBS is a great 240p downscaler and prior to Rama’s CFW there were no cheap and accessible options. It is a shame 480i is missing and that it won’t accept higher than 480p. If modern consoles catered for 640x480 (4:3) then the downscaled video would fit 4:3 CRT’s nicely. I’ll cover this scaler as well in the coming months

      It’s a great product, you get 3 ‘quick’ presets, 1 for power on, then the other 2 are accessible with the front preset buttons, otherwise the rest are selectable with the OSD. I love me some scanlines when I feel it’s appropriate but 480i looks great for modern games. I can pretty much guarantee it won’t work with lightguns given the lag as they need precise timings with the CRT. The guitar hero lag test is more of a human reflex test than anything. Dialling in aspect is a PITA but once optimised, you shouldn’t need to mess with it again

  • @shodan6401

    Not to sound like a noob, but can't the MiSTer FPGA deliver all of the scenarios that you want, without adding any lag (discounting the lag that's native to your widescreen digital processing)??
    Those are the benefits that interest me the most - retro games in native resolution and modern games downscaled but still in 16:9, with no appreciable lag. Particularly for modern shooters...
    (For example, when you were using the gyro in your controller, I could see the lag, though I've never used that feature, so maybe that's just the controller itself.

      Not a noob question at all. The Mister FPGA plays relatively older consoles. Whereas this is downscaling an HD console to 15KHz.
