I'd like that too
. However, it's extremely difficult to have direct video uploads at the moment - partly because it's technically difficult and beyond the scope of the forum software to manage that side of things, but also videos are often huge in size, which would mean that we'd need a much bigger server (which is extremely expensive).
I'm hoping that there will be a way to offload video uploading to another site, but from within the forum software. For now, YouTube seems like the best option (and then the link pasted in to automatically appear in a post).
