Problema com cores

[Leandro Viegas]

Prezados, estou tendo um problema no Premiere. Todos os vídeos que importo para qualquer projeto, tem suas cores alteradas. Já tentei de todas as formas corrigir porem não encontrei nada que justificasse essa mudança. Estou tendo que usar outros editores pois o problema não está se resolvendo. A imagem do lado direito é a original, porém ao coloca-la no Premiere ela altera totalmente.

That is a color management issue and all you need to know is here: Color management improvements in Premiere Pro

Averdahl's diagnosis is correct. You simply aren't setting your color management correctly. Please do read through his links!

Color Worskspace Lumetri Panel SETTINGS tab ... the tab NAMED! Settings.

• Set display color management, extended dynamic range when available (if on Mac), auto detect log, auto tonemapping to ON.
• Set Sequence color space to Rec.709.
• Set Viewer gamma to your needs.
• Set scopes to Rec.709 10 bit, do your color/tonal work.
• Export only with presets that do not have HLG or PQ in the preset name.

The above will get you good SDR/Rec.709 color settings.

Viewer Gamma Choices Explained

I don't know if you're on a Mac without reference modes, a Mac with reference modes, or everything else.

Rec.709 standards require the screen/monitor to apply a display transform to the video data of essentially gamma 2.4. All broadcast specced systems, PCs, TVs, streaming, Android, and Macs with Reference modes set to HDTV  ... follow the proper standards.

ONLY Macs without Reference modes show a different display transform!

For some idiotic reason, Apple uses essentially gamma 1.96 on all Retina Macs without Reference modes. Which presents a light image in the shadows of the same file data.

This happens with any app that allows the Mac OS to manage color. Such as QuickTime player, and Chrome and Safari browsers.

VLC player, Potplayer, and Firefox do not allow the Mac OS to do color manglement to Rec.709 media, so they show a more correct image than QuickTime player on Macs without Reference modes set to HDTV.

The image therefore looks more like on all other systems outside the "Macs without Refererence modes" ecosphere.

Premiere 25.x has Viewer Gamma Choices!

Viewer gamma 1.96/Quicktime will show an image within Premiere similar to QuickTime player, Chrome and safari outside of Premiere ... but only on Macs without Reference modes. It's not useful for anything else.

Viewer gamma 2.2/web is what most users should be using, not because "web", but because if you are grading in a normally 'bright' room the standards require grading with gamma 2.2. And most editors don't work in the really dark "proper" colorist's room lighting.

Viewer gamma 2.4/broadcast should be used only if you are in a very dark, near to but not quite, blackened room. That is the required setup for broadcast quality grading with Reference monitors and a 'bias' light on the wall behind the Reference monitor.
