Adding screenshots for interlaced pictures - the proper way!
1) load picture in vice.
2) set maximum emulation speed to 10%
3) take 2 different screenshots
4) ???
5) profit!
the result is somehting like this:
( sure, it's not perfect, but at least it doesn't fool people because there are 2 blended images )

Jailbird its not emulators fault,its the LCD/CRT monitor displaying at a frame rate other than 50FPS that fucks it up:) the emulated flicker is the same,connect your PC to a PAL TV via TV out on your gfx card and you wont be able to tell the difference. other than that i agree |

It would work A LOT better if todays LCD screens would actually support higher refresh rates, 75 Hz and up. A real pity that almost none do. |

It'd be even better if they all supported 50 Hz, or even 50.12...
A blended shot is much better than trying to emulate C64 interlace with animgifs or flash crap. It'll never look right on a VGA or LCD monitor, as they are physically different from an old 15 kHz monitor, and you don't get a stable 50.12 Hz animation.
If you want to visualize the flicker, the closest you can get is a 60/40 blend of the two frames, but it takes several minutes to create a screenshot like that.
It still doesn't look very close to the real thing, and it never will. So stop bitching about screenshots and look at the releases on a real C64.

For me, the only proper way of adding screenshots of interlaced pictures is to grab the two frames and blend them 50%/50%.
This results in a wonderfully coloured picture that is easy on the eyes.
Interlacing is a method, not a goal.
So when possible, revert to the static blended picture.
And get proper software to do it. |

there's no reason to become rude on this topic.
more than a decade ago I was the first who posted IFLI pictures in 136 colored images on my old site.
(routine ate funpaint2/Gunpaint & RAW picture data)
why?
emulators couldn't even deal with those special modes at that time (time of C64S & Power64 or something), so people who had interest into c64 gfx compo's couldn't see what they wanted when they didn't own a real machine.
the merged one is the best but doesn't really represent how good or bad it flickers on a real one when it isn't dithered to prevent flickering (the source picture that is).
ofcoz it's better to see them on a real machine but not everyone has that option or time to transfer it all.
so I/we just came up with options to bypass those problems.
If people didn't care about such options then there wouldn't be any emulators either which would be a great loss in c64(/and other) interest for sure. |

Or just avoid interlace modes at all costs. they suck.

I think it's irrelevant how well the picture on CSDb resembles the real thing in terms of flickering.
If you want 100% resemblance, you shouldn't even be grabbing shots from an emulator in the first place.
An emulator is the best looking result you can get in terms of playing C64 on a PC/Mac.
A 50/50 blend picture is the best looking result you can get of an interlaced picture.
Both are not 'like the real thing'.

wont take long and vice et al. will have the 2-frames-at-50%-blend option for screemdumps and then shortly after also for running vice.
Then it will be too late.
Its only due to the fact that vice became so "good" so fast that only few releases run in vice than wont run on real thing. I dont like interlace and I dont like it being used and I dont like many things :)
People will always see what they wanna see. Since I cant even decide if knoekis crap-flicker is the appropiate way or a fake picture of blended frames, I think it should be up to the self-determined scener to judge (and history shows how vaulable a sceners judgement is (see e.g. voting system :)
So do whatever you like and I will like or not like what is done. I think no simple rule applies here. As so often. Funnyly the neither black nor white issue applies to interlaced pictures in quite an extreme :) |

Guys, guys, guys...
The topic you're looking for is this one. Re-read it, please. The matter was discussed once (or twice). Yeah, just keep bringing up this issue every second year but here's a better option, you'll like it: use that friggin search function first which was placed on an easily noticeable place for a reason. Dear Mr. Knoeki, does the following picture ring a bell by any chance? :)
Quoting Knoeki
Generally I agree that interlace modes should be avoided if possible but some of them could look very nice on the real thing. If done right, an interlaced picture won't flicker like a stroboscope and your eyes won't pop out like in Total Recall after watching an IFLI for several minutes. Look, I've spent countless days pixelling interlaced shite and my eyesight is still on place. Aesthetically, some might like the flickering and the blur produced by it, others might not. It's a simple matter of taste.
And about the screenshots, I should rephrase the rules (hai, assiduous :).
You do not complain about or praise C64 graphics as long you're watching them on PC (especially as screenshots).
There are multiple examples of graphics that look much better/worse on a vanilla C64. I hate repeating myself, but for fucking's sake, boot up your machines which this scene is based on and try to limit the whining about screenshots to the minimum. Once and for all, they're god damn extras on a production page, and should remain as an induction to the real deal, and not something your opinion, vote and comment is based on. |

I'm embarrassed. I do ensure my innocence in adding non-interlacing, non-blended screendumps not only for myself but several persons in the scene
(for example Sebaloz).
I must be punished for trying to fool people about the standard of the C64 gfx capacities :D.
Oh, and I agree what Jailbird said:
"You do not complain about or praise C64 graphics as long you're watching them on PC (especially as screenshots)."
