Hi,
I work in IP-TV and telecommunication company and i do this kind of work all the time. I can setup web based solution for your video editor. To do this for server side i need php and ffmpeg, this has to be hosted on VPS, not a regular web server. So if you have this then it's ok and we can work or i can maybe buy this for you and setup for extra price. For more info open a chat with me.
Looking forward in working with you,
Reif
