Andy, One more thing, is this not like what current LCD's do with a 120HZ refresh rate where a film print is 24 frames per second..in that the exact frame is shown 5 times per second, hense no jitters? Not exact because nothing has to be drawn twice as much for each second, but in the idea of taking out anomolies that crop up when you have an uneven divisor. What I do know is this...what I argued over a year ago still holds true to now. MULTIPLE PIXEL representation technology for low resolution. I was made fun of then, what I knew was happening now. This is the future my friends. |

Another correction..sorry posting at work. One more thing, is this not like what current LCD's do with a 120HZ refresh rate where a film print is 24 frames per second..in that the exact (24)frames is shown 5 times per second, hense no jitters? |

Supposedly doing a gotcha on Advance MAME vs MAME and completely ignoring my quote is how you often work. --- End quote --- I'm not sure what you find wrong with his quote. AdvanceMAME won't work correctly without a CGA capable video card. Neither will Soft15khz. The ArcadeVGA also has a low enough pixel clock to produce 15khz signals. ??? --- Quote from: genesim on May 15, 2009, 12:43:34 am ---One more thing, is this not like what current LCD's do with a 120HZ refresh rate where a film print is 24 frames per second..in that the exact (24)frames is shown 5 times per second, hense no jitters? --- End quote --- If you are referring to the artificial 'smoothing' of film on 120hz LCDs (called motion plus, motion flow, etc depending on manufacturer), it's not just showing the same frame 5 times (that would look exactly the same). It's actually inventing (approximating) frames in between and produces artifacts if you look closely. This is besides the fact that it makes your movies look like cheesy soap operas or home video, and IMO ruins much of the artistic properties found in film. Do you actually like how it looks? I have it turned off on my Samsung. |

How are you "inventing" frames when the it is an even divisor? 100hz Samsungs used Motion Plus because of the difference. Don't get confused with the jargon correction for their obvious uneven problem. http://www.cnet.com.au/samsung-responds-to-100hz-motion-plus-issues-339287355.htm Motion blur happens when the response time on old LCD's are to slow. This also has nothing to do with 120hz. Actually if anything was invented, it was when televisions were 60 subfield because of the obvious unscalable issues with film standard being 24frames per second. http://www.lcdtvbuyingguide.com/lcdtv/what-is-120hz.html 120hz does not "create" frames. It only repeats the signal. It cannot "create" what isn't there. As for the the quote, the part that is deceptive is that he is saying only PCB's and CGA cards put out 15khz...aparently this is not so. Arcade VGA does this..."not just PCB's and CGA" cards. That was false from the first post. And I was correct from my first reponse when I talked about the 15khz to 31khz scaling. If Cheffo wasn't aware that I was right, he should have just said so. I am even gave him a link and he still didn't seem to understand. |

Oh and also Motion Flow from Sony is also a corrective measure from non Film sources. It is a way of compensating for poor signal. A higher refresh rate does not make "cheesy", if anything it makes it more accurate because it keeps you from losing information that you might not have got becuase of a "judder". Not pertinent to my point though. In a 1080p/24 Bluray, it is a 1:1 ratio. No motion flow, motion blur..etc. is needed. |
