What self-hosting websites provide you links that will work with Amara? I would like to be able to upload my video there and get a link.
So if your file is large and you don't already have your own website, your best bet is probably to upload your video on a video hosting platform like vimeo or YouTube, which both work with Amara. Or on archive.org (Internet Archive), where you can host all kinds of files.
Best subtitling wishes,
