welcome to the forum. there’s been some previous discussion about videos. see https://forum.inaturalist.org/t/videos-for-observations/5408, https://forum.inaturalist.org/t/upload-videos/5426, etc.
i think the gist of the past conversations is that while there’s interest in accommodating videos, there’s a lack of resources to realistically make that happen, and currently, other things would take precedence over a push to handle video anyway. but if you have connections to some deep pockets or some technical resources, maybe that could get things reprioritized…
