    Unfortunately I don't think new CRTs will ever be manufactured again, which is a shame -- I recall seeing articles about new CRT technologies as recently as 2004 or so that surely never reached production and more recently I'd bey quantum dot phosphors could have been integrated into CRTs, so the technology clearly hadn't reached its peak.

    That shader you're using was made to mimic a 240p 15khz monitor, not a high resolution VGA monitor that you have there. Even if it's a CRT it's generates a much more pixelated image than a display those games were intended for. Also, I recommend playing around with Black Frame Insertion in RetroArch because digital displays sucks when it comes to motion resolution compared to a CRT. You need 120hz BFI at least to even come near 60hz on an analogue display.

    The Retroscaler 2X has a problem with the 480p resolution option on a TV, does this too? Or it displays normally and give the option to activate progressive on GameCube games?

  • @pandaengineering
    @pandaengineering4 күн бұрын

    The device is not a scaler so it only converts the signal as-is from Component to HDMI. Doesn't change the output format. I was able to test 480i, 480p and 576i and they all worked fine on the TV supporting these via HDMI. All computer monitors I've tested with didn't support interlaced at all. Note, that some games switch video modes like Super Mario Sunshine at bootup that allows you to pick 480p or 480i (I think it starts on interlaced so it means no picture on a monitor that doesn't support it). 480p works for me with source from PSP, Wii and Wii running GC games (via Nintendont). With mentioned Super Mario Sunshine it allowed me to play in both interlaced and progressive just fine and the TV recognised the HDMI format too correctly in both cases. I have some Wii games patched for widescreen and 480p and these work as well. Sorry, I don't have a proper GC to test with. What I've also recently learned is that some games look better unpatched on 480i (apparently RE4 is nicer on the eyes interlaced), but it's up to personal preferences.

    I still have SD CRT, but I get better picture quality on modern high resolution displays thanks to CRT phosphor emulation (CRT shaders). The thing is, the SD CRT blurs the image way too much, so even 480i/p doesnt look nearly as sharp as it should, while CRT allows me to emulate PVM monitor as well, so I get CRT like image, but with much better sharpness and I have never seen PS2 games looking that good at standard 480i/p. To perfectly emulate CRT phosphor mask, people need 4K OLED with HDR and use CRT PVM HDR shaders in retroarch. The reason is, only HDR allows to have CRT phosphor mask at 100% opacity, so colors and brightness will look absolutely perfect. SDR shaders will always have problems with colors and bloom (which must be used to brighten the image), but it's still possible to get awesome results. I spent a whole week configuring SDR CRT shaders and I'm happy with the results.

    I still have SD CRT, but PVM HDR shaders looks even better in both 240p / 480p. In this video you arent seeing 4K and HDR, so CRT phosphor mask cant be emulated perfectly. With 4K OLED and HDR, it's impossible to tell the difference between the real thing (CRT) and the emulated phosphor mask (at least on the static image, because you would meed 1000Hz OLED to match CRT motion quality), that's how good CRT shaders can look.

The only advantage CRT still has is better motion quality, but on the static image results look stunningly accurate. In fact, I prefer the emulated image because CRTs (and especially PVMs) are very small and do not allow me to change the phosphor masks to my liking.

    The thing is that I could only record in 8K at 30fps, since even with h245 it was basically at quality of very clear 4k footage that I uploaded. At higher fps I also had all kinds of tearing on CRT as it seems it often was actually more around 59 Hz and I don't really have a professional camera that would be able to sync well enough at that level. I went with the 30fps even though I'm well aware that it's showing the ghosting that isn't there IRL, but at motion the recording was looking the closest I could get to what the eye sees without any artifacts of CRT drawing the image. I'm sure it can be done better 😊

    Interesting comparison, thanks for sharing. I personally will stick to my CRT because of how good fast-paced sidescrollers like Sonic, SMW, Super Metroid look on it, it's the main reason I haven't replaced it for an OLED. Retro games running at 60fps on a 60hz CRT will give you such smooth movement because of the way CRT work. The flickering gives you the illusion that the object you're following is at infinite fps because the eye can't perceive the black frames. I've tried OLEDs with black frame insertion and it's just not the same, you still get some blur, AND you lose half the brightness. I was goin to suggest you to do another comparison, now with a sidescroller, but it's honestly a very difficult task to do since you'd have to move the camera laterally and at the same speed the level is scrolling, and record it at 120fps, then slow it down to see the blur difference. Recording it with the camera standing still would be pointless. Anyhow, I'll keep waiting for the day a brand releases an OLED with black frame insertion that actually works well.

  • @Adam_Lyskawa

    It's pretty weird - the OLED screens you've tried were not the best quality. 60Hz refresh rate is not even very high for OLEDs. They are even faster than LCDs, and I have a LCD that has 165Hz refresh rate. This is way, way, way smoother than 60Hz. And yes - I doubted it's even possible to tell all the difference until I just saw how it looks and, what's the most important - how it affects my gaming. It's probably like how the myth of "better analog audio" was born. Early digital audio devices were poorly designed, bad quality, so compared with high quality analog audio they sounded worse. Even today you can buy badly sounding multimedia player. But it's not the tech. It's just specific products.

Si je recharge la caméra avec le câble USB sur l'ordinateur alors le voyant rouge clignote sur la caméra.Il y a un voyant sur la caméra qui indique que la batterie est chargée ? Cette caméra n'est pas à détection automatique de mouvement donc c'est l'utilisateur qui doit l'actionner à distance avec son téléphone mobile, c'est ça ?

    The only way I know for sure that the camera is charged is when the blinking red light turns to steady. It seems that whenever you charge it, it runs very slow and doesn't want to respond to button presses, so I only use it when it runs on battery and charge it when it's off. App shows for me the battery state in the right upper corner of the preview, but it doesn't show how much is charged when connected and if it's done charging, so I look at the red light if it's still blinking or not. There is no motion detection, you need to start/stop recording manually. There is no way to delete the videos with an app. In the app you can only format the whole microSD card to erase all files. I usually just ignored the app and managed the files with USB OTG cable on my phone, because it was faster than the wifi connection. For me the date and time resets every time I turn off the camera and it only synchronises with phone time when I connect the app. I just turned off the timestamp from the videos because it was reset on all recordings.

    In this case turning them on and keeping the button pressed for a longer time (about 10-15seconds) nters them into pairing mode so they can become discoverable on your phone. It's important to keep the button pressed down even after they've turned on. There should be a jingle and the light should change blink red and blue.

    After testing it again with RCA cables, connecting headphone jack disables audio output via HDMI and you can listen only via headphones regardless of the A/D switch. When headphones are disconnected I get sound via HDMI only when the light is off. I only have devices with audio RCA jacks, but I suspect now that this button may be for switching input between RCA jacks (analog) and coaxial audio input (digital), but I don't have hifi or DVD with that kind of output to test this.

    Hello! I've got a Playstation 1 PAL (not PAl M or N, only pAL) and my TV is NTSC. I've already tried the conversor PAL - NTSC from Ali Express, but it didn't work (funny how it only works for the 2 frist screens... but when it enters in the games.. only some colors work, it gets weird). My question is: is this converter PAL (without being M or N)? Thanks!

  • @pandaengineering
    @pandaengineering2 ай бұрын

    Sorry, but I can't confirm which specific version of PAL it outputs (might even be a semi-PAL signal, just converting colors). None of my TV show the signal type they get so there is no way to confirm this for me. I would recommend against using this specific converter as it has poor signal at the output. Best choice for PS1 is SCART cable or S-video and then convert this signal to what you need with an external converter if you run a CRT. If your TV has HDMI you might be better off getting a converter for that since it will be more flexible with input signals (although cheaper ones might cause some more lag than what TV would normally get with analog inputs).

    If you mean on the old joystick side with Game Port, the only good way to well understand how it's connected is to "ring" through (check using the continuity function on the electric meter) and write down what each pin on the connector is connected to what cable on the board. Then you can figure out the function on each pin (you can easily find Game Port pinout on Wikipedia). This should make it easier to understand how they made your controller because in practice Game Port can't be really nothing more than 2 analogue sticks + 4 buttons.

  • @pandaengineering

    The only idea I have is looking into the manual, there should be a table at the end (for Samsung it's "Standard Signal Mode Table"). The thing about this is that you can't say for sure what kind of horizontal or vertical frequency your specific device will use and it may just fall out of range. I also would assume that no monitor without TV capability has any way to display interlaced signals. Reading a little bit about Wii itself it apparently renders 480p internally to 640x480, but outputs that to 720x480 which is rather non-standard, but for whatever reason worked on my old monitor. Depending on the graphics card you might be able to simulate that kind of resolution and test monitor for yourself beforehand (I had better luck with AMD GPU than Intel built-in because Intel would scale internally my custom resolution and output a native HDMI monitor resolution).
