P: Help! Green Shift When Viewing ProRes Files Exported by Premiere, Within Premiere Mac ARM

I recently upgraded to Apple Silicon (on an M1 Mac Studio) thinking that most of the kinks have hopefully been worked out, but here's a new one for me.

I'm testing with a flat (Log C) ProRes MXF from an Alexa. I place that in a timeline based on the source res, and export out a ProRes 4444 at max bit-depth with 16 selected.

I bring it back into Premiere. I overlay it on top of the flat MXF... and there is a significant green tint visible. Lumetri scopes indicate the same.

Thinking it might be the way Premiere is interpreting the MXF, I also tested taking an H264 clip, exporting out a ProRes 4444 of a section, and bringing that back in - lo and behold, a green shift.

Now for the most interesting part - I brought the ProRes 4444 that premiere created, and the flat Alexa clip, into Davinci Resolve. I put them next to each other in a timeline and toggle between the two clips while looking at the scopes - and wouldn't you know it - no green shift.

So, it looks like for some reason, Premiere's importer/viewer is applying a green tint to the ProRes clip that is not visible in the actual ProRes export. What... do I do about this?

Display color management is disabled. Viewing through GUI via HDMI but again, scopes are indicating a difference within Premiere.

PLEASE HELP.

Mac Studio w/ M1 Ultra, 128GB Ram running Mac OS Ventura, Premiere Pro 23.1.0, Resolve 18.1.2

That's clearly in a QuickTime ergo ProRes 'wrapper' ... so yes, it's ProRes.

Not just from the .mov, and "QuickTime" up top of your png. Look down, it says explicitly this is ProRes.

Log media is not a format, it is simply the math used to encode the file. It still has to be encoded into a wrapper/format. Sony often uses H.264, others do whatever they do.

Full RAW media does have typically a specific file type. Such as BRAW ... but log is always in something.

Everyone's mileage always varies ...

Summary

Apple Log footage recorded on iPhone 15 Pro (HEVC 4K 30fps LOG) displays incorrect color during playback in Premiere Pro on Apple Silicon Macs.

When the clip is paused, color appears correct (neutral).

When playing, the image becomes noticeably green-tinted and flatter.

This occurs even without any LUT applied, and regardless of interpretation, color space settings, or display configuration.

Non-Log iPhone footage (standard HDR or SDR) plays back correctly.

The issue is present in both Premiere Pro 25.5 (Release) and Premiere Pro (Beta) 26.0.0, on macOS Sonoma 14.3.

System Information

Hardware:

MacBook Pro M3 (2024)
Internal Apple XDR Display (P3–1600 nits)
External LG UltraFine 5K (same result)

Software:

macOS Sonoma 14.3
Premiere Pro 25.5.0 (Release)
Premiere Pro (Beta) 26.0.0

Renderer: Mercury Playback Engine GPU Acceleration (Metal) — default, unchangable

Footage format: iPhone 15 Pro, 4K 30fps, Apple Log

Steps to Reproduce

1. Import an iPhone 15 Pro Apple Log clip into Premiere Pro.
2. Create a new Rec.709 sequence (or just drag and drop the clip into sequence)
3. Leave the clip as-is (no LUT or color interpretation).
4. Observe the Program Monitor:
• When paused, colors appear correct (neutral).
• When playing back, the image shifts green and loses contrast.

(The same happens even if the clip is interpreted as Apple Log → Rec.709, or graded manually with the official Apple LUT in Lumetri.) -> Using official Apple LUT!!!

Expected Result

Playback and paused frames should look identical, with consistent color rendering.

Actual Result

Paused frame: Correct color (neutral and accurate).
Playback: Distinct green tint and desaturation.
Issue persists with or without LUTs, both on built-in and external displays, and with all color management settings.
Exported files look correct, matching the paused frame — confirming that the issue only affects real-time playback.

Additional Observations

The bug occurs across clean projects, fresh preferences, and cleared media cache.
Both 25.5 and 26.0 Beta
It affects only Apple Log clips — standard iPhone footage plays back normally.
It appears regardless of:
- “Display Color Management” (on/off)
- “Color Space Aware Effects” (on/off)
- “Viewer Gamma” setting (1.96 or 2.4)
- “High Quality Playback” (on/off)
- HDR Graphics White (Nits) -> 100/203/300
- Display preset (P3–600 nits, BT.709–BT.1886, etc.)
- HDR disabled in macOS custom display preset
Changing the sequence preview codec or reinterpreting footage has no impact.
Renderer option cannot be changed on Apple Silicon (Metal-only).

Conclusion

This is a Premiere Pro Metal playback pipeline bug specific to Apple Log footage on Apple Silicon Macs.

The real-time playback renderer does not consistently apply the correct color transform for Apple Log media, resulting in a greenish cast and desaturated image during playback only.

Paused frames, exports, and non-Log media are unaffected.

Given that Apple Log is now a standard iPhone Pro workflow, this bug severely limits accurate monitoring and grading on macOS.

Attachements:

1 screenshot while paused, 1 screenshot while playing -> Green tint!!

As you can see I have been messing around with this for a few hours now and i'm almost going insane. Hope someoen can help. 🙂

Hi @daan_0322 - Are you sure your media clips aren't ProRes? There is an issue with ProRes clips playing back with a green tint. As a workaround please turn on "high quality playback" in the wrench menu

Can you right click on your media file and select Media File Properties... and then post a screenshot.

Hi Jamie,

Thanks for your response. The high quality playback seems to fix the issue for now, thank you so much!

I think ProRes/ Log is the same thing in Apple terms, but I could be wrong. They use different terms in different places. Attached a screenshot.

Cheers.

This solved my problem with the green tint during playback: In the Program Monitor panel, click the wrench icon and select "High Quality Playback".

Hope it helps anyone else experiencing the same issue.

Have you tried the auto detect log and auto tonemapping process instead of the LUT process?

I'm having the same issue with CLog2 footage.

I shot everything in CLog2 and then through the "Interpret Footage" feature in the project panel, I applied canon's technical CLog2-to-CMT709 Lut. Looks great on the timeline until I try to use proxies. After creating proxies, there is a green tint during playback. When it's paused it looks fine, just like the full res footage, but when I hit pay there is a green tint on the proxies being played.

I have tried updating everything (Mac operating system so Sierra, Premier Pro version to most current 25.3) to no avail.

Note: if I shoot footage in in Rec709 and then create proxies, it works fine. The issue is when I shoot in CLog2 and then apply a technical lut through "Interpret Footage", then it casts a green tint during playback.

@Kevin-Monahan Due to the lack of upvotes/responses on here and on Reddit, I had to just let it be for the past year. I have not updated to check, but I do see that this is a known issue on Adobe's page, finally:

ARRI ALEXA 35 LOGC4 footages experiences a green shift in preview post render in M1-based devices.

Are you able to shed light on what y'all have found on your end for this issue? If I'm recalling correctly, the issue originated not with the 35, but with the mini LF. Are you seeing the shift only in Previews? Has this been addressed in the latest updates?

Thanks so much!

Hey there, @b00nm00n,

I appreciate the response. Sorry to hear that the issue has not been addressed yet. I would have to get a product team member to answer this question. Perhaps @Fergus Kousha might have a comment. I hope to find out more info for you. Sorry for the problems this has caused you.

Thanks,
Kevin

Hello!

I have a project in Premiere shot with Alexa Mini, Prores 4444, 3.2k - I have a really weird issue now sending a few plates for vfx: when I export a plate of a clip at 200% speed, the export comes with a slightly green tint that just disappears when I go back to a 100% speed.

Has anyone had the same problem?
