As a product it could be an independent video verification service.
On-demand: A client wants to release a video and make sure that it’s trusted. They contact the company first, some process is done to make sure that they represent who they say they represent, and the content is hashed and added to the blockchain prior to release.
Ongoing: when a client uploaded a video to the web, the system would automatically grab it, generate the hash, and add it to the blockchain along with the metadata of where it was found and who the client was.
For large clients, it could even include video cold storage.
For marketing/promotion, the company could automatically process public media from well-established social media feeds.
