Jpg with color change at premiere 2020

awh11 has a great answer ... I'll just add that Lightroom tends to work in a modified version of the ProPhoto color space, a bit wider gamut than the video sRGB that Premiere works in to comply with the Rec.709 broadcast standards. So that image directly from Lightroom could be in a wider gamut.

When you select the Jpeg option to export from Lightroom, make sure that in the file settings you specify the sRGB color space, as that is very close to a Rec.709 file. And to get closer, I do think if you take the file to Photoshop from Lightroom, you could specify even Rec.709 for the output color.

But as awh11 noted, color management is not nearly as exact as many users assume. No two devices will show exactly the same color, even side-by-side.

Well one thing to keep in mind is that Premiere works in a Rec 709 environment. Any items you import into Premiere it assumes to be Rec 709, the timeline is Rec 709, and your exports are (usually) Rec 709 (unless you're using a codec that can specify otherwise.)

Starting with variation in luminance, this is probably due to the gamma differences between sRGB (which I'm guessing your photo is) and Rec 709. The following example may not be 1:1 as to what happened, but just to give you a sense of what CAN happen:

• Your still image is originally sRGB (gamma 2.2)
• Premiere has assumed it to be Rec 709 (Gamma 2.4) as this is default behavior
• You export a Rec 709 video
• You watch it in an environment which forces it to be seen in sRGB (for example YouTube), now gamma has shifted up one extra time from 2.4 to 2.2, adjusting the luminance values a bit further than you expected.

This opens up a big ol' topic on color management and the unfortunately somewhat hopelessness of trying to get everything to look the same everywhere which I will not get into now for everyone's sake. That said if you really want to have a photo match Premiere's environment, send your raw image to Photoshop and set the color space of the document to Rec 709.

As for the poorer gradiation, I am guessing this is because your still image has a higher bit-depth compared to your Premiere export (and resulting JPEG capture) which are likely both 8-bit, depending on your export settings. Unavoidable if you are going down to 8-bit at the end of the day, but you can improve it a bit by checking "Render at Maximum Depth" in Premiere's export settings. Your end result will still be 8-bit if encoding an 8bit codec, but it will be rendered out at its full depth before doing so and that should help improve it a bit.

PS. Great shot by the way!
