Gamma shift on exports with Prores and H264 with Quicktime

Hey everyone.

Im using the latest Premiere Pro.

Are they gonna fix this problem any time soon? It has been years since we all are having this problem and the only response from Adobe it's "Hey, professional calibrated monitors works well..." but, hey, Adobe, de you know that the vast majority of your clients are not grading on professional monitors, and are probably using iMacs, Macbooks and PC prosumer screens? And most of them are not high end professionals? What happens with educational envionments? Why do we need to have this problem on Premiere when DaVinci Resolve (free software) and FCPX (a $300 lifetime license) are not having this issues?

I just want to make an edit, grade it and export what I'm seeing on Premiere monitors. Is that so hard Adobe? Why insist on not patch this kind of issues, or at least give the option?

It is not a bug!

Unless things have changed DaVinci resolve will have the same problem by defualt.

Does you rendered image look fine if you drop it back into the Premiere Pro timeline?

You video will look different if broadcast and played back on someone's TV. Is that a bug or is there a difference between YUV and RGB? Video frames that look awesome on your computer screen will look washed out when you print them on paper because the RGB will be converter to CMYK.

You can change a few setting in DaVinic Resolve or add a adjustment layer in Premiere Pro. All software will have color space issues. It is normal. It is not a bug.

It IS a bug. Again, this wasn't a problem with Premiere v12 and earlier, and it is NOT an issue in DaVinci Resolve, I've tested it multiple times--it's what made me almost swtich to DaVinci Resolve--the only thing that kept me from switching to Resolve is that their AAC encoding sucks and sounds like a 96kbps mp3, and it can only be adjusted to 192kbps in options instead of 320kbps like every other program can. I have to choose between gamma issues with Premiere or sound issues with Resolve.

In Premiere, doing the adjustment layer makes it look darker than the original. None of the awful workaround answers that people have been giving actually work right--the LUT makes everything darker than the original, and the adjustment layer gamma adjustment also makes everything darker than the original. I just want the output files to look the same as the original files like it did in v12 and earlier and like it does in DaVinci Resolve.

If Adobe didn't artificially block people from installing earlier versions, none of this would be a problem to begin with. Shame on me for upgrading my computer. V14 runs slow as molasses when editing as well (it's like editing on my old computer in v12), and people have complained about that, and the problems all started in v13--the panels not staying where one puts them, crashing issues, slow editing, and the gamma issues. It's why I never upgraded to v13 last year, I tried it for a while, and swtiched back to v12, but in 2020, Adobe took away people's choice, you can only go back one version number now.

Obviously something has changed between v12 and v13 when it comes to gamma. I want v12 behavior (as well as DaVinci Resolve behavior), not this new "adjust your monitor correctly and you won't notice the problem" behavior.

MPEG4, Blu-ray and AVCHD use the H.264 video codec. H.264 is used for broadcasting. A lot of professional cameras use H.264.

Back in 1995 all the video content you seen was on people's TVs whether uncle Bob's VHS tapes or the local news.

In 2006 some people watched 95% of their video content on the TV and 5% on the computer.

As of 2020 some people watch 90% of their video content on the computer and only 10% on the TV. At one point in time all video content was NTSC/PAL broadcast compliant. That is what type of editing Avid, Premiere Pro and FCP were designed to edit.

I can set up DaVinci resolve correclty during export or I can apply and Adjusment layer in Premiere Pro. It is possible Premiere Pro will get more export options.

You don't have to set up anything in DaVinci resolve to get it to export the way that Premiere v12 and earlier exported. I've said numerous times that Premiere didn't have this problem until v13. Vegas doesn't do it, DaVinci Resolve doesn't do it, HitFilm doesn't do it. This is something that ONLY happens in Premiere v13 and up. I've tested this multiple times.

And again, the adjustment layer does not properly correct things. I've already given proof of that. And no, having to do an adjustment layer AND change contrast settings is not acceptable. I shouldn't have to completely destroy a number of color shades in order to have a video with the right gamma. As I've said--with every conversion there is a loss, with every filter there is a loss.

If 90% of video content is viewed on the computer and only 10% is on the TV, why did Adobe purposely change their software in late 2018 to only cater to that 10%? Can you give an explanation for that? Or are you going to keep excusing them?

As I also said, if you can show me a media player for Windows that can "properly" play the exports from Premiere, I'll be glad to take a look. I bet you won't have an answer though.

You're totally right. In version 2018 (v12) and earlier, this was never a problem.

I made a thread about this problem, and I'm so annoyed with someone who basically keeps giving the argument "if you have your monitor properly calibrated to industry standards, you wouldn't notice the problem". I even gave examples of what happens, and the only advice I'm given besides that guy telling me that if I adjust my monitor so 8,8,8 looks the same as 0,0,0, I wouldn't notice the problem, is to use either an LUT or a gamma adjustment layer to cover up the problem.

A helpful thing to be able to see the image in the Premiere interface/monitor the way it will actually render as a finished product, is to go to Preferences, General, and uncheck "Display Color Management". Yeah, it doesn't look as good, but at least you'll know how bad it will look when it actually renders/exports as a finished video.

Attached are images showing what the images are supposed to look like, and the color values of each section, and what Adobe Premiere does to the same images in the render/export.
