i made a animated Gif (Gimp 2.8) but there is something wrong.

i made an escalator with 2 persons on it, they move up the stairs in 12 steps.
i made 12 different .XCF's for every step one.

Before converting to animated gif i make the XCF's 1 layer each. when i use the option FILTER > ANIMATION > OPTIMIZE (difference) the animated gif leaves black lines when the persons move (see picture attachment) the export file is very small so that's ok

Use Optimize (for GIF), not Optimize (Difference). Optimize (Difference) doesn't take into account that GIF cannot do partial transparency (and neither can Filters-Animation-Playback), so it's not really useful, unless maybe for animated PNGs.

Thanks for replying....your answer did not helped for me, the problem stays. i optimized each picture and i optimized the new (12 pictures) layer. but the lines stays. but i understand now better the difference so thanks for that...

Can you post the full GIF (and possibly the original XCF) somewhere?

I agree we need to see the full file.

I've never used GIMP for animation, so I could be very wrong, but to me this looks like poor selection technique during the process of cutting and copying the figures as they climb the escalator - and not a problem with saving the animation process as such.

How about converting to indexed color mode before you try optimizing it?

When done right, the "Optimize" command (in either flavor) should make no visual difference in the resulting animation.

Plenty of images... except an XCF that would look like the source of an animated GIF?

But I don't see anything technically wrong with "animation optimize difference.gif", in particular I can't see the "shadows" in your screenshot (tries with Firefox and Gwenview, besides Gimp)

i just noticed it did not happens in google chrome but the same gif shows the black lines in windows explorer 10
strange, and ofcourse i always openend the animated gif in explorer hihi, can you try it in explorer 10 if possible ?????

Sorry, I quit Windows-ing several years ago, and it did a lot more good to my health than quitting smoking :)

Now, what kind of additional evidence do you need to start thinking that perhaps this supercalifragilisticexpialidocious Microsoft piece of software of yours could have a bug?

(I do still use Windows and) I agree that it is a bug in IE10. The gif renders fine in IrfanView and all other browsers I have installed.

I haven't seen the modified GIF, but the original had the lines on FF 20 on FreeBSD 9.1

Don't judge the GIF quality with IrfanView, because it's actually quite buggy when displaying animated GIFs.

The animated gif is fine... Windows Explorer is the problem, it does not

allow

to project an animated gif when it is showed resized, rescaled etc. and of course i tested the gif in Windows Exploer, after tips of you i tried the animated gif in Google chrome, and there was no problem....
