Problems with colors while playback a video

Report · Jun 18, 2019

Hello everyone!

I'm struggling with common problem with desaturated colors after render a video. But I have some other question while previous problem is still not solved.

I color graded my footage and everything is fine while I'm watching it. When I stop the video, colors become desaturated and same desaturated color are later in exported video. I don't get it why I have "good colors" while I'm moving the video on timeline and they are different when I stop the vid.

I've never had this problem before until I bought Atomos V. This problem pop up only on footage from EOS R+Atomos V.

Is there any chance you know why is it happening?

That's a weird one... I'd like to know what people have to suggest.

Might as well give some basic info while waiting...

you on pc or mac, what O.S.

what version PPro

If you have video card, what is it

are you using color managed ( the ICC thing )

Stuff like that.

Don't know your camera.

Is it set for limited or full ?

I only have old ninja 2 so, do you have choice of limited and full on yours ?

what codec you putting on SSD from ninja ?

This will be a tricky one maybe... basically have to find someone using the same stuff and compare results...

Luckily I have a SDI out on my computer and I compare a color calibrated primary monitor to that video monitor for my own stuff to get as close as I can to rec 709 gamma 2.4 while working. If I export to web I change the export to rec 709 gamma 2.2

good luck !

PC

Newest Version of PPro
nVidia GTX 1070
color management from graphic card full (0-255)

Camera Canon EOS R + Atomos Ninja V, 8 bit 4.2.2 Rec.709

Monitor NEC Colortuned (calibrated)

info I would give in your case …

windows 10 pro latest update

custom built computer 32 gig ram ddr3

GeForce nVidia 6 gig

nVidia setting " let program manage color " ( nVidia card basically 'off' re: color )

why? My reason is the Eiso primary is color managed with a color calibration software and an optical gizmo that you put on screen...and there is a constant usb connection between monitor and computer to keep track of that.

I don't use any ICC stuff per se … the color software IS the management. Along with the NLE I use ( the color settings I choose in NLE software)

The ninja is DNxHD 220X, 4.2.2 ( I think it's YUV in mediainfo ). So it comes out as a mov with DNxHD .

Eizo is calibrated to rec 709 gamma 2.4

The stuff re: full vs. limited gets kinda complicated... and I ended up putting color bars into the NLE and using THEM to tweak the final luge and color tweaks... on video monitor ( SDI ) and eizo.

In the end what looks right is far better rule of thumb then everyone's 'opinions' , including manufacturers.

P.S.

the only time I notice difference between playing and stopped ( in timeline) is when there's a lot of motion ( motion blur at, say, 24fps )… so when played it looks more clear than when it's stopped on a single frame... but that's not a color difference for me. It's just the blur.

I have to thank you for starting this thread.. cause thinking about stuff made me come up with a possible solution to something that's been bothering me since yesterday. I'm using an NLE UI that shows a certain color ( yellow is the one bugging me ) on thumbnails of clips when doing certain stuff ( setting flags). Mine look slightly less bright than they should be ( drifting toward red … like toward 'orange' ).. and since my video monitor only displays what the program monitor sees ( not the UI ) I think I can maybe take a screenshot of the UI, stick it in timeline, and see what the video monitor does with that …

I seem to be in a constant world of tweaking and perfecting stuff...

Well guys I came back to the bottom of everything and made a new sequence. This time I didn't make a 25fps seq but 50 fps like I recorded the footage and problem seems to dissapear.

So apparently I was hyped too early. In PPro colors are fine but after render colors are still desaturated 😕

How you view the footage matters. The only image you can trust is from a hardware player going to a calibrated display.

One thing I noted, is your comment that your graphics card is set to full rather than limited.

That is never appropriate for a proper Rec.709 workflow. The material is naturally displayed correctly to the monitor with the correct limited range settings. This is a typical thing for us non-colorist types to reason into.

But a fully trained color management person like Steve Shaw of lightillusions.com/Lightspace has tons of white papers on this.

I'm having the same issue on a Macbook pro. Are there any updates?

There is a TON of information explaining the nature of the problem.

Apple created a new and unique color space, starting with the P3 color space, which has been used for two different theatrical release versions both using a gamma of 2.6, slightly "darker" in shadows than the broadcast standards using 2.4.

And in their OS and apps are using apparently a scene-referred gamma around 1.96, rather than the display-referred 2.4 gamma of all other systems.

So your Mac if in native mode uses a wider and slightly skewed color mapping than Premiere and nearly all other professional standards.

As it's bigger color space, when it plops X coordinates on the screen they aren't the same color as an sRGB/Rec.709 screen would show.

And that gamma tends to lift shadows.

The QuickTime player and Safari and Chrome browsers all use that scene-referred gamma also. Firefox apparently stays with attempts to apply the scene-referred standard gamma.

And nothing seems to just look at the media, read the color space tags, and display according to those.

So it's complicated. And there is no easy "fix". I understand you can go into the OS and select an ICC profile more suited for sRGB/Rec.709 production.

Or, within Premiere you can use the preferences option to "Enable Display Color Management" and Premiere will read the ICC profile and attempt to remap the screen to give a proper view according to standards.

It won't look the same after export on your Mac, but will look proper on all other systems running standards. And the vast majority of systems out there.
