I can’t seem to find an answer to this, but if there is, please direct me there.
Uploading video is capped at 100mb on the Creator plan. Substack allows videos of many GB, so I’m wondering how one uploads video natively. If the Ghost site is self-hosted, can that upload limit be increased up to, say, 4GB?
The upload limit is effectively determined by the web server that’s serving your Ghost site. If you’re self hosting, you have full control over that, indeed.
Specifically, if you’d use NGINX, the web server that Ghost recommends, you’d adjust the client_max_body_size in the NGINX configuration:
Poor form though, upload to someplace like BunnyCDN Video and then only share the embed so performance is good for everyone and not a drag on a server.
