I'd have to see the result of the 2 scans per frame @120Hz in person on a CRT before I would decide that it would need motion interpolation. The old LCDs used to interpolate 24fps / 30 fps video into something that looked like 60fps (or 120 fps), and the interpolation looked like crap to me (soap opera effect), but on many of these sets I never saw an option to turn it off.marqs wrote:Doubling the refresh rate induces both motion incoherency (2 strobes/scans per frame) and latency (half a frame at minimum) so it's not without tradeoffs. You can do motion interpolation to mitigate the former (remember the 100Hz CRT TVs) but that bumps the lag even more. That said, 240p 120+Hz output should be doable on the Pro model.Josh128 wrote:orange808 wrote:In any case, if theres some technical reason as to why this mode would induce blur on a CRT ( I dont believe it does with MISTer or Retroarch), the tradeoff would be worth it to me.
That said, interpolating 30fps video, which is already very easily discernible to the human eye, into 60 or 120 fps is a different ballgame than simply doubling the draw of each 60fps frame on a CRT. I have a feeling I would prefer the raw doubling of each drawn frame as is vs. adding some interpolation to it, so the only added lag would be about 8ms. That would be perfectly acceptable to me.
I'd love to see it in person, I have several VGA monitors in my possession. Ive heard the new Retroarch is capable of the exact same thing with certain video cards that can still output analog video, if anyone is familiar with it please point me in the right direction, as it would be a good indicator of what to expect from this OSSC Pro.
This looks absolutely fantastic to me. https://www.youtube.com/watch?v=C_pYmNG89RQ https://www.youtube.com/watch?v=C_pYmNG89RQ https://www.youtube.com/watch?v=EZNmxTGmZBo
