I’m looking for a marketplace theme that allows people to sign up as vendors and then, once they are approved, upload videos to sell through the website. What would be the best option for this?
You will need and very good web server which will handle large amount of videos. You will need multivendor plugin and template which is support multivendor plugin.
Yeha I was thinking using ReHub’s multivendor theme - http://revendor.wpsoul.net/ and incorporating EDD and some other plugins.
On start be sure that is template compatible with plugins. Sometimes my clients install 123 plugins on site and there is conflict between plugins or theme and plugin some template without any support and non developer friendly and ask that I change s many things that is easier to make new template than change that template.
