Rendering Video Online

I've been scouring the interweb looking for a solution but haven't found one yet. Hoping my fellow SO geniuses can help.

How can I have video rendered online? I want to host an application on my server that allows my users to render their videos online. So if you imagine using a web interface much like Adobe Premiere Pro to arrange video clips and pictures, set it to music, I need to then have the final arrangement rendered to mp4 or avi, etc. Kind of like how Google creates its Google Memories, taking your pictures, adding music and rendering a video.

Any help pointing me in the right direction would be greatly appreciated.

Cheers
