Thanks for letting me know. Handbrake is no stranger to me, but didn´t know that either. But haven´t used it since i realized that it only has the 8-bit pipeline.
Didn´t expect it to have just 12 GB but nice 😃
That’s why I stopped using Handbrake, because it reverts to 8bit during processing. The final filesize can vary wildly with crf since its all about content. So for example, on one 2 hour film 4K crf 20 could result in 20GB and in another film-- half that.
