Uploads over 2 mb

how do I upload videos over 2 mb? 2 mb is too little for a video. In my case I want to put a 6 mb in the header area

Hello there,

WordPress core system allows up to 8MB for video header. It’s been officially mentioned in the Make post. However some hosting provider usually limits it to only 2MB maximum or lower. You should check it with your hosting support. Read this blog post that’ll tell you the steps how to increase it.
