Washed off colors when uploading online

Hello!

I have been suffering over a year now from washed off colors when uploading videos to the internet. I'd like to solve this issue for good.

Please find attached some pictures for a review. It has a comparison of Frame io, YouTube and VLC desktop player. I'd like the video to be viewed online like the VLC player. Frame seems to be desaturating the most. Both examples are in Firefox*.

Davinci Resolve settings are as set on to: Davinci YRGB color managed, SDR, SDR Rec. 709. Input Color Space: Fujifilm F-log. Material has been shot with Fujifilm cameras.

Please help me fix this.

*Firefox and Safari does not have difference in saturation. The issue must be in the file or how online servers handle these files.

what are you rendering as?
There will always be a difference between players, UIs, browsers and web players unfortunately. ...and televisions ....and projectors....

Have you tried setting "Color Space Tag" and "Gamma Tag" to Rec.709 under "Advanced Settings" on the Deliver page? Windows or Mac?

I think this applies here.

How it looks anywhere besides the calibrated display is simply beyond your control.

I really would give that a try, Konstantin. Made all the difference for us here.

This is a well documented issue with Mac OS

Video shows the best work around I have seen.

to summarise his "ultimate" settings:
use Davinci YRGB
monitor rec 709 2.4 (on calibrated reference monitor)
on output apply a CST going rec709 G2.4 > rec709 G2.2 (do this on timeline mode)
render prores 422(HQ)
Force tags 1-1-1 (colour rec 709, gamma rec 709A)

Not so much an issue with MacOS, but with players and streaming services not respecting the same flags.

Wow! So much help and love Thank you! I'll look into this information that you provided and come back here with new results.

If you want to go down that rabbit hole, here is a ton of information for you:

How does people seem to live with this issue without going to that rabbit hole and losing one week of time to investigating how to preserve colors?

I'm losing colors when I upload my material to Frame io app. I want my clients to see my videos as vibrant as they are in Davinci or rendered and viewed on VLC. But for some reason, the colors are very washed off no matter which browser I use. Please help me sort this issue.

These screencaptures are from Resolve - VLC - Safari Frame io - Firefox Frame io - OSX preview

I want my clients to see my videos as vibrant as they are in Davinci

Then you need for them to get the video off the computer and onto a properly calibrated display.

You need to take the variables which can (and often do) alter the image out of the signal chain.

This gamma and color shift I see in my own well calibrated imac screen. If the shift is so big here, I must wonder how huge it is when clients view these files on their not-so-good screens.

I did get this answer from Frame.io

If you are creating files in Resolve and are seeing a gamma shift (ie, the video on Frame.io looks brighter or more "lifted"), you may need to adjust their colorspace and gamma tags in the Deliver page. More information about Gamma shift is attached below-

QuickTime videos use metadata called NCLC tags to tell the operating system and the player what colorspace, gamma, and primaries to use to display it correctly. NCLC tags are designated with a series of three numbers, like this: (1-1-1). Each number represents a spec from the NCLC table (the full table is included at the bottom). You can find the NCLC tags of a QuickTime file by pressing cmd+i in QuickTime Player.

On Frame.io, the NCLC tags need to be either (1-1-1) (SDR Rec709) or (9-16-9) (HDR Rec2020).

When using Resolve, by default, it will export Rec709 QuickTime files as (1-2-1). Frame.io will create proxies from the original using (1-1-1), creating a gamma shift. The solution is to have the user export their QuickTime from Resolve with (1-1-1) NCLC tags.

When exporting from Resolve, under Advanced in the Video Settings, change the Color Space Tag and Gamma Tag from Same as Project to Rec709. This ensures that their file is exported with (1-1-1), and Frame.io won't create a gamma shift.

Essentially, since the 2 in (1-2-1) is "unspecified", the operating system and/or player will assume its own gamma (or transfer function). On Mac, that's Gamma 2.2.

I don't see this as a fix as I'm already using advanced render page settings and I have already set REC709 in the tag settings.

The Rec.709-A gamma tag changes the playback of the file from "straight" Rec.709.

Do you have that monitor completely accurate for full broadcast Rec.709 with gamma 2.4?

This whole mess with Apple and b-cast standards being different is a royal pain.

Don’t forget that the viewer’s screen should be calibrated as well for the colors to match, even with perfectly encoded and tagged material.

Congratulations -- I think this the 3,289th time this has been asked on the forum.

A note to @Peter Chamberlain: I'd suggest that maybe a page of the next Resolve manual be devoted to this issue (and granted, it's not a Resolve problem per se), just to explain it.

Standard boilerplate reply to the o.p.:

Read these:

"Grading for Mixed Delivery: Cinema, Home, and Every Screen in Between" by Cullen Kelly

and

"How to Deal with Levels: Full vs. Video"
by Dan Swierenga
https://www.thepostprocess.com/2019/09/ ... l-vs-video

and I think both cover the issues and the solutions very well.

Understanding color management is also helpful:

"Color Management for Video Editors"
https://jonnyelwyn.co.uk/film-and-video ... o-editors/

The above articles will explain why things change on different displays, different playback engines, and the importance of calibration and color-managed outputs.

I generally try to export a second or two of SMPTE Bars at the head of the project, and I import the file back into Resolve to check it on scopes to verify all the levels are correct. Using calibrated displays is a must -- without that, you have no idea what you're looking at. We also accept that the basic picture is going to change a little bit on different devices, because that's life.
