Also, you'd be good to at least watch the developer videos that cover HIEF/HIEC & HEVC. This is where I got my information from. Argue with the Apple development team if you disagree. We've covered my mistake regarding the settings options already. Everything else checks out. The information in those videos is far more than what one would gain just searching would.

A lively discussion about these new advancements is something I'm excited about and would like to entertain, and can hopefully offer a more enriching experience related to OP that may even address their concerns more fully, including correcting errors with grace rather than your war hammer. We'll be be doing this our way thank you very much. We're not interested in marching up and down the square today. We've got plans.
