Imgur not accepting an MP4

I was hoping to post a 10 second, 25.5 Mb video, but Imgur won't accept the original iPhone file, nor subsequent shortened and/or converted via iMovie files. The are grayed out in the Upload browsing panel's "suppported files" list. (Latest Macbook Air, Monterey 12.2.1, and all other apps up to date.)

Is there a comprehensible, non-kludge (remember that word? ) workaround? Please keep in mind I flunked out of MIT and Cal Tech. Tinypic's gone, and other hosting sites I'm aware of are too invasive or annoying with ads.

According to the Imgur help topic on this, the maximum size allowed for videos is 200 MB. If you can convert the video into one of the accepted formats, it should work.
