In the latest Beta build, we have updated Canon SDk to version 2.4. With this, we have also added support for files from Canon 1DXMKIII.
Please try out the feature and let us know how it works for you.
THIS IS AMAZING. Though, it defaults WB to 15,000.
The second thing is, the copy/paste of the master metadata isn't a feature yet. (for copying to other clips)
Thanks for your Feedback. We will be working on it.
Thanks for your feedback. This issue regarding color temperature is fixed and will be available in next Premiere beta build#31.
