Screenshots of Interlace Pics

I’m interested to know what people’s thoughts are on screenshotting interlace pics…

On C64GFX, we do things a bit differently to CSDb. Generally, we care more about the original art than how it’s presented - so we’ll host logos with all the “extras” removed (scrollers, textual information, etc). But of course CSDb screenshots are of how things are actually released.

With interlace pics, it’s more complicated. In theory we should be displaying animations at 50fps (usually) switching between 2 screenshots.. but I’m lead to believe that that could cause battery drain and other problems on devices - plus the FPS probably wouldn’t be 50.

Some sort of blending was suggested.. or simply choosing alternate pixels and merging to create a full-res pic.

The latter is what I’ve tried with some pics .. eg. Some of Leon’s. It looks good and it looks like it’s true to the original creation - I’d hazard a guess that he simply drew these pics at full 320x200px resolution on most of these, actually, rather than drawing on C64 in an interlace editor?

Eg. https://c64gfx.com/image/168046

I toyed with the idea of blending the 1px offset pictures (frame 0 and frame 1).. but I’m not sure that that’s correct either.

Others have suggested some fairly complex blending schemes that presumably show more like it would be on CRT - and I think this is where the 1,000s of colours problem comes in (evident on many CSDb screenshots). This seems unfair since regular MC/HI screenshots don’t get the same treatment.

Anyway, interested to know thoughts… both for CSDb and for C64GFX.com

YEAH! Now we are talking!
Your new version of interlace, plus my version of css blending and we are ready to go!

btw. There are 2 versions of interlace with MC. With, and without 1 pixel horizontal scroll. It is important to keep that if we want the images to be as true to the original as possible.

Thanks to Gordian, we now have interlace pics interlacing on C64GFX :-)

Leon’s page is a great example of them: https://c64gfx.com/artist/1373/leon

Yeah indeed, thanks A LOT to Gordian!

I am not a big fan of interlaced pictures at all, but this result seems very suited!

No at all, it was pleasure for me:)

P.S. We add also JS script which prevents flickering empty/black frame(s) when they are not fully loaded (sometimes one of the frames was loaded faster than the other one).

Somehow on the website it doesnt look nearly as good (interlace stuttering all the time) as in the css anim in the thread :/

Hmm doesn't seem to work in Safari nor Firefox on a Mac (e.g. https://c64gfx.com/image/160940), but Gordian's examples work fine.
Works in Chrome only.

@Groepaz: Yeah, I've been trying various techniques to remedy the stutter but nothing works.

The previous css anim was working perfectly here :)
