Unfortunately there is currently no way to add videos into Google Posts through any technology platforms (including LocalClarity), as Google's API does not accept the video format for attached media. While you can add a video individually when creating a Post through your Google Business Profile (GBP), there is no way to do so in bulk. This could be something that Google changes in the future, but as of now, videos can only be done manually through GBP.

GIFs is another medium that is not supported through Google's API. Much like video, GIFs have to be included in Posts through GBP and not through any other platform.
