Developing a macOS app that targets HEVC/HEIF, I was wondering this myself.
Now get this--HEVC encoding is faster on a last-gen iPhone than it is on a top-of-the-line current MBP!
- dmitrygr 9y agoBecause intel does not have HEVC encode hardware and A11 does?
- akaru 9y agoNo, they both do. And I'm talking about the A10 even. Still faster than an i7/Iris Plus 650. Of course, the graphics hw is killer in iPhones, so it's not such a surprise. But it makes you do a double-take.
- brisance 9y agoThat’s interesting; do you have a reference where I can read more about this?
- astrange 9y agoYou can always make an encoder faster than another encoder. What you have to ask is - how good is it for the speed? (This is called rate-distortion optimization.) Better yet, how good is it for the bitrate and speed? (This is the really hard part.)
- jack1243star 9y agoNitpick, but RDO refers to trade-off between bitrate and distortion (quality), IIRC
- astrange 9y agoSometimes you're limited by time more than bits, but they're both rates.
- ulfw 9y agoI have noticed how slow HEVC encoding is on my High-Sierra 2017 MBP too. Would love to offload some of those tasks to iPad Pro. Would you know of any HEVC encoding apps?
