I see no artifacts.

[ami_stuff]

There are visible artefacts (or trashed palette) with this build (and my own) at the beginning of the video and also later:

​http://johnvansickle.com/ffmpeg/builds/ffmpeg-git-32bit-static.tar.xz

Do you see the same output from MultiShow/AWC and FFmpeg?

[ami_stuff]

with 64bit build artefacts are visible as well

[ami_stuff]

here is the same anim first splitted into separate frames like this:

buildanim SPLIT amigapark.an5 frames/amigapark

and next re-splitted back to anim:

buildanim ANIM5 frames/amigapark001 ap2.anim5

(​http://aminet.net/package/gfx/conv/BuildAnim20)

[ami_stuff]

see attached files, "anim16-27" decodes correctly, "anim15-27" not (1 frame difference at the beginning)

buildanim ANIM5 amigapark015 anim15-27
buildanim ANIM5 amigapark016 anim16-27

info via MultiShow ("View/Show Info"):

anim15-27: "Palettes: 2"
anim16-27: "Palettes: 1"

[ami_stuff]

here is one more sample:

​https://www.datafilehost.com/d/3cb89a19

plays fine with MultiShow/IFF Manager/AWC

fails with iffanimplay, but it's buggy :)
