We are operating on content on physical portable hardrives from the studio. A webapp would be pointless and inefficient (these videos are hundreds of gbs). Most of the internal software we write for our content team is basically glorified macros. They need to adjust 100's of videos sometimes, and doing it one by one would take months. If they can define what needs to be done, an engineer can usually get it done in a few hours or days instead of weeks.
