Posting a "movie" of the Tempest App

I noticed at post no. at post no. 47, July 20, Lightning in the app, which was posted to owners and bug reports, that a “movie” gif? was posted showing values in the App changing with time.

Is such a posting allowed/discouraged on this board?

If not, how is done? Thanks

I used my phone’s screen recording to record the app and then used an online mp4 to GIF converter.
