When working with raw source files in Adobe Premiere Pro, it's important to know each camera manufacturer's settings to demosaic (debayer) the log format using their respective color science, color space, and gamma.
In this demo, we'll use Blackmagic braw files as an example.
Double-click to select a raw clip on your timeline, then from the Effect Controls panel, click on the Source tab. This is where you'll find the raw source settings:
Next, select Decode Using Clip to enable access to the raw source settings, then select Gen 5 for Color Science:
Set the color space to Blackmagic Design and Gamma to Blackmagic Design Film, then check the Highlight Recovery and Gamut Compression boxes:
To apply these settings to all braw clips on your timeline, click to select the raw settings header, then click copy:
Next, in your bin, select the braw master clips (click + Shift) that are part of your timeline, then click paste:
Adjust the source ISO, color temperature, brightness, and other values for each clip in the timeline as needed to bring them to a base grade. Fine-tuning these values in the camera raw settings is more effective than the Lumetri corrections:
Alternatively, add a camera-specific input LUT in the Lumetri panel to bring your log image to a base grade, then fine-tune the camera raw settings further per each clip as needed:
Use the same process for other raw source types with their own color space and gamma settings as provided by the manufacturer:
