On Windows 11 22H2, using XnView MP 1.3.1
If an animated PNG has over 1000 frames, it will fail to play on XnView MP. This does not occur with GIFs or animated WEBP images. These animated PNGs play correctly on other programs that support the format.
A couple of animated PNGs are attached below.

Re: APNGs with >1000 frames do not play
Thanks to your detailed description I can reproduce the problem.Pierre.
Re: APNGs with >1000 frames do not play
This problem is supposed to be fixed in XnView MP 1.4.0. Please check and confirm the bug fix here.

Re: APNGs with >1000 frames do not play
It looks like the limit for APNG files to animate is now 2000 frames, instead of 1000. Other animated image formats with high frame counts still play correctly.

Bumping this -- the bug still occurs on XnView MP 1.8.3 as described in my last post with the 2000 frame limit.woot000 wrote: Fri Mar 03, 2023 12:15 am It looks like the limit for APNG files to animate is now 2000 frames, instead of 1000.
