| I've just been experimenting with ProRes, DNxHR, DNxHD, 10-bit, 8-bit, etc in various combinations. (All on a Mac while waiting for the PC). The differences are obvious on a scope, on the eyes not so much. I will say that DNxHR 444 RGB 10-bit is extremely clean though the highlights that hit 100 IRE in ProRes appear to peak at about 98, maybe 99. Robert W.

Wrong. Each developer has set their own preferences for said codec when implementing them.

All those settings people don't like to mess with, well those are there for a reason to control your output. Unfortunately they can be difficult to understand for the layperson so presets are offered by most apps. Guess how well those presets match at the core level. They don't. :) > > So the fantasy of finding that one great codec doesn't technically exist because of those variables, but most ignore this information or refuse to believe it's true. > > Just saying. ;) > > > David Torno > 818.391.6060 > -------------------- > www.sydefxink.com (work history) > https://vimeo.com/davidtorno (work samples & breakdowns) > https://gumroad.com/davidtorno > http://provideocoalition.com/dtorno (tutorials) > > "The most useless day is that in which we do not laugh" > -Charles Field > > > On Dec 11, 2017, at 9:55 AM, Brian Higgins <AE-List@media-motion.tv> wrote: > > > > I don't think there is one, but there isn't a lossless ProRes codec that I'm aware of, either. |
