isn’t webm a movie format? The image-format equivalent to it should be WebP, which is superior to jpg and png in every way, so it really should be supported at some point. There is a PR for that, but not yet finished…
@DivyamYadav currently this format is not supported. But you can use Cloudinary. I believe that will work just like @arthurjacquemin showing in the above post.
Hey. Check my repository, it work with the default upload plugin (local storage in public/upload folder) and cloudinary (and I think with other providers but I don’t test) https://github.com/Kazdan1994/strapi-webm-cloudinary
