Colors look extremely saturated after export.

Dear FCP Forum Team,

I've shot a short clip on Sony A7III with Atomos Ninja V. (4K 25fps, Slog2 and ProRes422).

I've used the Ninja V clips and edited my video. After I export it I get overly saturated colors. What might be the reason? I've turned on "Legalize" option while shooting with the Ninja V. May that be the reason for this weird issue?

Attached you can see screenshots before and after export.

Would be glad if someone can help me. Thanks a lot beforehand.

Best regards,

Can

Turn on your video scopes, that will tell you if it's oversaturated or not for sure. Vector scope and Luma scope.

As FCPGuru wrote videoscope are the main tools for grading. But, where do you check your videoclips? external monitor? computer display?
I'm currently only using my iMac 27" 5K Retina display calibrated with Datacolor SpyderX . I know that best choice would be an external broadcast auto calibrated monitor but I feel that I can get decent results with an iMac panel
About your clips, What LUT were applied to Slog2 files and when were applied? at moment Ninja recording? in FCPX inspector window clip before to edition? last at grading after balance and levels correction ?

Generally, if the FCPX viewer looks correct and the exported file is oversaturated, this tends to be a gamma issue. As mentioned above, knowing what you are viewing the exported file on is helpful in analyzing the problem. This can happen easily in Divinci Resolve also, but there are more options in Resolve to match output gamma curves of the playback display to the viewer. In your case, using FCPX, I would check the color profiles of the display you are playing back the exported file on. If it is the same Mac screen as FCPX is running on, check your display preferences in the OS preferences. You can remove, modify or repair any color profile that may be set for that display. As another form of test, share a still frame from FCPX and likely that will look oversaturated as well. If so, the color profile is probably damaged or incorrect.

Knowing what you are viewing the output on is critical. If you are viewing it on the same Mac screen you used for editing and it looks over saturated then it is probably a profile issue as stated above. If you are viewing on another device that is not calibrated then all bets are off.

For example, I recently finished a video and watched it via AirPlay to my Samsung TV. The colors were way over saturated. Like you, I wondered what the heck? I then watched it on a Panasonic TV and the colors were more like the colors on my MBP, and when viewed on the MBP the colors were spot on.

I’m having a similar issue where my export looks great on : MBP, dell external monitor, iPad and iPhone all look great, but when I aur-play to my LG TV it looks super high contrast. Doesn’t make sense to me.

I don't really understand what you're saying. "iPad and iPhone hi I received, but when airlines layer to my LG it looks super high contrast."
