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 )

if blending adjacent frames makes a picture look better than it actually is then this makes a picture look horribly bad. i can count 5 fps in your example.

yes, but people can still watch in an emu. people often judge pictures by just checking a screenshot, which is not the way it should be done, as a picture looks fucking awesome, while in reality it flickers like hell.

Several browsers, like Firefox, limit the minimum frame delay, that's why the above animation won't look right for many people.

At least it's better (read: less deceiving) than just blending the two frames together.

In reality (eg on a C64 going into a TV) they don't flicker like hell, that's reserved for viewing them in a web browser as an animated GIF :)

I also tried the same with Flash once, it still looked crap.

I did some testing with that ages ago aswell, Flash came out quite decent but it all depends on the picture ofcoz

the examples of Sorex are much closer to be acceptable

Animated interlaced gif gives really mediocre results. But that Sorex's flash thingy is quite decent.

1. watch it on real shit.
2. blended images are closer than even sorex's stuff, which is nice but still misses the pal artefacts&blur&exact 50fps.

But you could add pal artefacts & blurryness to each separate frame.

I actually like it :) (well, not that i like interlace at all very much..)
