Does Interlace really suck ?
Back in 96 IFLI was all the hype, nobody really cared about the flickering if the picture was pixeled with a good technique.
Back in 96 Multicolor sized pixels were considered nice and not blocky, hires wasnt so overhyped.
and I think the shifting viewpoint to a great extent boils down to the wide used emulators. Everyone uses emulators today, and yes, interlace looks like shit in them, and multicolor pixels looks like huge square blocks in them.
Everyone should take some time and check the best laced pictures on a real thing with a real TV, and check multicolor / hires difference. I remember back in the time thinking that hires is actually to HIGH resolution, as a normal TV can hardly display such a pixels.
The lesson is: Interlace is only a flickering nightmare if not watched on TV, and multicolor pix has ugly big pixels only if not watched on a TV. |

I really don't think interlacing looks all that bad in an emulator. Sure, not as nice as the real thing, but quite close.
IFLI is a bit overrated, though. MCI looks just as nice in most cases. |

Turning on "Exact PAL emulation" in Vice really improves the appearance of IFLI pictures. |

I think laced stuff looks OK on my 1901 (separate Y/C), and if the artist spent some time minimizing the flicker it looks great. Still, you can't beat the nice, crisp pictures you get with UFLI. And yes, I know it's hell to work with :)

I have never tried IFLI and probably never will because I am sure I will suck at it.
Never did like interlace much but the skills of some working with IFLI are superb and thus excellent pictures do exist.
It is true that it looks a lot better on the real thing.
I´ve noticed that IFLI displayed in Vice has an irregular pause between the screens.
Haven´t checked if that´s also the case on a real C64.
And maybe it´s just me.
I don´t hope for a decrease in interlaced graphics.
But I want to see more UFLI! ;)
It´s not that time-consuming if you only use it for filling up your sketch! |

Jailbird, nopes. I don't use a Y/C cable but i still can see every hires pixel. Using a composite cable produces quite a sharp pictures on some C64s and C128s, others have quite a blurry picture here (especially C128DCR).
Anyway, seeing the flickering is not exactly hard to do. It's 25 Hz and every human can see it very clear. Only old TV sets and bad monitors reduce the flickering because of their long-glowing phosphors, but a good (?) PAL monitor even shows flickering on 50 or 60 Hz. |

Graham, ofcourse you can see every hires pixel, even I can. I said that a TV can hardly display it. Just display a 1 hires pixel wide vertical line, and display a 8 pixel wide vertical line. You will see that the 1 pixel wide line is has light gray color and not white. Because of this I disliked hires wireframe vector stuff when I still watched stuff on TV. Also you did the PAL filter for Vice, so you should know that chessboard style dithering mixes like a dream, and on a real TV at most combinations you cannot even tell apart the original pixels that are intended to displayed. |

If you want white hires pixels, use Y/C cable. If you use composite there is a low-pass filter with a cut-off frequency around 4 MHz (depends on your monitor/TV) on Luminance which will make hires pixels darker. However, they are still hires...
Also, chessboard patterns in hires dont look ugly with an Y/C cable aswell. The colors blend perfectly, but the luma doesn't mix so you will still see the chessboard. |

Graham, we agree on those. However I've used the real thing 90% without Y/C cables, and I've written my previous post based on such experiences.
To let everyone know again: I opened this topic to make some justice for the flickering and non hires gfx's on c64. So if anyone wants to see them in full glory, then just _DONT_ use Vice. You wont get a 100% correct 50hz screen even on a 100hz monitor, and still not counting the blurnyness and afterglow of real TV sets. Pictures will look 10x better even with a monitor with a Y/C cable, but for best results use a composite cable :) |

It would be neat if you could set vice to do a 70/30 blend with the previous frame. It would lead to ghosting artifacts in some cases, but it would make laced graphics look much nicer.

What a great topic. I honestly didn't know any of this in 1996. Really. |
