Record HTML Canvas On Server Export To Video

Hi, I need a script that will work on a server (UI): 1. An html5 Canvas that will Display svg, mov, png, jpg, gif, jquery animations - effects, Text (size, color, type), all the elements are resizable and drag and drop, each have default duration, I can change the duration of each element - preview available at low resolution (from canvas) 2. Project based (save,save as, load) - Slide based, the script - ffmpeg will record the slides as video - mp4 hd, each slide have its own items. 3. User accounts (admin, users), Include ffmpeg queue, let user know when video is ready - user will have a list with all his videos (status - rendering/ready), can download, edit, delete. 4. Admin can see a list of all the users, delete, limit their number of videos/slides per day/month Thanks Sample UI Attached
