Light Red Background After Using Ultra Key

I am trying to edit a video that was recorded on an Elgato 4K60 S+ in standalone mode using an SD card. After I finish the recording, I import that file into Premiere Pro. I then have to go into Preferences under Edit and, under the General Tab, I check "Display Color Management". Doing so gets rid of the washed-out image I was getting in the video... awesome 🙂 The problem I'm now running into is that whenever I import something into the Project that has a green screen that requires the use of the Ultra Key Effect, a light red background is left behind, as shown in the image I attached. I'm pretty new to Premiere Pro, so I have no idea how to fix this issue. Any help would be greatly appreciated.

Highly recommend you set the Elgato to Rec.709/sRGB ... it's a ton simpler still. Less confusing to be doing "standard" video.

 

With the timeline/sequence selected, you can go to the Sequence main menu, Sequence Settings, and check your working color space. I again recommend staying with Rec.709.

 

For any clips recorded as Rec.709 that will be all you'll need to do.

 

With any clips recorded in an HDR form, you need to right-click on the clips in the Project panel.

 

Select Modify then Interpret Footage.

 

Go to the bottom, and set the Override-To option to Rec.709.

 

And make sure the sequence you have is also set to Rec.709.

    Thank you so much, Mr. Haugen. For everything. I followed your steps and that fixed it for me. I'll just have to record in standard and forgo the HDR beauty, lol. The only workaround I could come up with is to take the images that I create in Canva and put them into Photoshop and eliminate the background and THEN import them into Pr. and sidestep the whole "Ultra Key" issue. But that's an extra step for an already lengthy edit I tend to have, so I don't know if I want HDR in my videos that bad, lol. But, again, thank you for all the help. I appreciate it so much.

      That file is in a form of HDR ... PQ, to be precise. Do you really really need to be working in HDR? That is still the Wild, Wild West of video, unfortunately.

       

      And then what is your sequence working space?

        I'm pretty new to Premiere Pro, so I don't know if I fully understand what a sequence working space is...but All Panels is marked under the workspaces option under Window. Is that what you mean? If not, I'm sorry.

        What is the codec of the file from that Elgato unit? Actually, showing something like this of the file ... the free utility MediaInfo of the file's header, in MediaInfo's "Tree view" ... would be very helpful.

         

        Drag/drop the file onto that applet's desktop icon, when it opens go into Tree view, make a screengrab, drag/drop that screengrab onto the text reply box area here. Like below.

          This is from the recording that I captured with the Elgato 4K60 S+. Hopefully I did this right.

          That is most commonly a GPU driver issue. If you're on an Nvidia GPU, try going to their support page. Look for the older drivers, and do a clean install of the 517.40 STUDIO driver. Do not use the game-ready drivers.

          I had Nvidia support help me rollback to the 517.40 STUDIO driver and got it downloaded and installed, restarted my PC and it's still giving the same issue 😞 When I use the eye dropper and the green background with Ultra Key...instead of it eliminating the background...it just changes it to that light red background.
