I’m experiencing a color/gamma issue with proxies in the latest version of Premiere Pro.

I’m working with Fujifilm X-E5 footage recorded in F-Log2.

The original footage is correctly interpreted in Premiere as Fuji F-Log/Rec.2020, and my sequence is set to Direct 709 (SDR). The original footage looks correct.

The problem occurs only when I enable an attached proxy.

What is strange is that the proxy file itself is completely correct when imported into Premiere as a normal, standalone clip. I have tested several types of proxies, including ProRes Proxy, and I have also created a proxy that was actually converted to Rec.709 using a LUT.

In every case:

Original footage without proxy: correct
Proxy file imported separately into Premiere: correct
The exact same proxy file attached to the original: image becomes noticeably brighter/washed out
Disabling the proxy immediately returns the image to normal

I have also tried:

Manually setting the original footage to Fuji F-Log/Rec.2020
Direct 709 (SDR)
No LUT
LUT conversion on the proxy itself
An adjustment layer with the LUT
Creating proxies through Premiere's Ingest/Proxy workflow
ProRes Proxy at half resolution

None of these change the problem.

The fact that the exact same proxy file looks correct when played as a standalone clip, but becomes washed out only when attached as a proxy, makes me believe this is an issue with Premiere's attached-proxy color management/playback pipeline rather than an issue with the source footage or the proxy encoding.

same for me. automatically linked proxies are flatter/lower contrast than the original clips. but when the exact same proxy file is added to the timeline as it’s own clip, the color matches the original footage perfectly.

somehow, the color in the ingested/automatically linked proxy files are being identified and displayed incorrectly. 26.5.2 build 5

Hello @Adobe master 3000

Welcome to the Premiere Forums. We could also use a little more information to help us replicate this issue in house so that we can properly study it for a solution.

Could you tell us a little about your system specs?

Premiere Version: How to find the exact version of Premiere you're using.
Operating System: Specify Windows or macOS, along with the version.
Chip (Mac Only): Specify which M-series Chip or CPU/GPU combo.
GPU and Driver (Windows only): Please let us know your video card and driver version. We recommend updating to the most recent version; for NVIDIA users, we strongly recommend the Studio version of the driver.

I’m also wondering if you would be willing to share just one test file of your original and the proxy version in a private upload link I can DM you.

Thank you,

Amy
