This is brilliant - I'm amazed how humble you are in calling it a stupid website. I've always wanted to do "something" with video development, just because it's always been a massive black hole for me. Any tips?
There's lots of work doing less sexy things like building workflows for transforming existing video libraries to something to use in various OTT platforms. Think B&W films or older TV programs. Understanding old video formats and how to prep them for modern platforms is something that not everyone does well. Of course that would require deep dive into the history of Film->Video.
There's also lots of options on developing supporting software to do non-sexy things like storing descriptive metadata and making it available. Transforming closed captions, subtitles and other ancillary file formats that support video.
