Hi @flapili. Thanks for reporting the issue. Sharp seems to support animated output but it is not enabled by default. I've to check more but will be solved soon by either addition of new animated modifier or enabling (at least for gif) by default.

Just added experimental support for animated modifier. It forces output to be webp because default build of libvps cannot output animated gif (lovell/sharp#2012) Also as a currently, you cannot resize animated output (lovell/sharp#2275)

Released in 0.6.2

Let's track in #53 for later improvements.
