Question

Invisible Lut on my imported clip | Clips aren't flat compared to VLC/Davinci | Bug?

Hello every one!
TL;DR My Video should look like flat but for some reasons it's automatically colorgrades it.
OG Vid without any changes in Premiere: It's not flat, but it should look flat

Proxies On: (Proxie has the same wrong Color)

Same Proxies Imported separately: (Right Flat Footage)

OG Vid in Davinci (same result in Every Media Player) Its Flat! This is how it should look like in Premiere


If I import my original footage into Premiere there is a huge color-shift. Watching it in any kind of programm (VLC Player Quicktime, Davinci) it looks normal and flat.
When I export the OG file with the Media Encoder to MOV 4444, import it into premiere, the new exported file shows right flat colors.
I did a test with the build-in Proxies. I createt some Proxies in Premiere to toggle them with the proxie toggle button. Here the Proxies shows the same wrong colorspace BUT when I imported the proxie file like some normal clip, it again shows the flat normal colors. 
It seems like premiere uses some kind of invisible Lut on to the OG Mov and I realy don't know why.

Like with anything else, there are things about Master Clip that are very nifty ... and other things where I've got requests in for ridding IRRITATING behavior.

 

You can paste "attributes" to a clip in a bin, and it goes into the Master Clip tab for that clip. Which is great for when you are say wanting to spread "neutralization" work around a bunch of clips. And you can copy/paste from a Master Clip tab to clips on a timeline.

 

However ... on a timeline, it will only put the paste into the "regular" clip tab. Naturally, without the MC effects ... even if that is a clip with the same nature such as BM raw.

 

That's the sort of behavior I find annoying.

As Ann pointed out, but many do not know or understand ... there are cameras that produce media typically in log or raw formats, and for some in a proprietary version of those. Their files have extensive metadata entered into the media files at the time of capture with the intent of being able to change the settings for the file in the editing application, rather than in the camera at the time of capture.

 

Including even changing the ISO (for raw files) ... the gamma functions ... color space ... all sorts of things normally "baked into the file" in the camera.

 

For those cameras, the controls for that extensive and advanced metadata are found in the Master Clip tab for media on a Sequence. You find that tab in the Effects Controls panel or the Lumetri panel. There will be a Master Clip tab and a tab with the filename of the media. Most color correction/grading would be done on the 'regular' file-name tab. But the specific controls for say r3d files, Sony log, Arriraw, and others, will appear in the Master Clip tab.

Thank you for the clarification!

Yeah I totaly get that and it does makes sense.
With some kind of notification in Premiere or a note in the Timeline Effect Controll I would have come to such conclusion as well.
But it seemed more like a bug than a feature at the beginning.


Still at the end I personaly would prefere if premiere would not set a LUT if it gets these meta data information or at least give the option to deactivate it.

Thank you Neil and Ann for taking your time helping me in this situation!

Screenshots are too small to read anything (this is a forum issue)

Did you check the masterclip for the footage?

    Yes! Thank you!
    I didn't know that there is an autmatic applied Lut for some files but it makes sense.
    I also didn't know the possibility to apply effects on master clips.
    I learned something today.
    Thank you for you quick help!
