Do any studios have any free online training available?

I'm only aware of Hugo's desk, Tony Lyons, FXPHD, Alexander Richter, various youtubers. I was wondering if there were any training/guides/documentation from big studios. It's hard to find tutorials about topics like pipeline, the science-y parts of image creation like linear workflow, footage ingest, creative treatment documents, etc. I realise that for a lot of companies they may want to protect their business IP but thought it would be worth asking to see if anyone is aware of training from the companies themselves.
