Youtube Compression Saturating and Darkening Videos after Upload

[tokun1]

Hello Group,

I'm having an issue with YouTube adding saturation and darkening my videos after uploading the videos to Youtube. Please note: I'm viewing on Firefox web browser and it looks terrible, but, this is the odd part, the video looks fine when viewed on Safari and Chrome. I've uploaded a .h264 from Final Cut Pro 10.4, and an Apple Pro Res 4444, I got the same results after uploading to YouTube. I don't use compressor anymore because FCPX has a Youtube setting. Has anyone else had issue with YouTube compression, or is it just perhaps the Firefox browser? I also tried the file uploaded to Vimeo with the same results, bad on Firefox, looks good on Safari and Chrome.

Any help would be most appreciated!

Thank you!

-Tony

Are you sure you upload your video using video range as opposed to full range?

I'm not sure what that means, what is video range or full range?

That is great information, however I'm still not understanding how to create and export the proper color range, (I always make sure my color profiles in the Luma curve do not go above 100 and do not go below 0 when it comes to level adjustments. So how does it relate to my settings in Final Cut Pro 10.4? The most curious part of the issue is why would the colors look just fine when previewing the video on Safari and Chrome, but NOT on Firefox? I may need to switch the range check in FCP 10.4, *See photo...FCP 10.4 It looks like it is set to Rec 709, it was off, is that the setting you are referring to?
