Can you convert iPhone 15 cinematic footage to Apple Pro Res Log

[LifeBack]

Ok… rookie mistake!!! I did a music video with the iPhone 15 Pro Max using Filmic Pro. However, at the first location, I forgot to shoot through Filmic Pro. The first location was shot in Cinematic Mode, and I DID NOT shoot it in Apple Pro Res. All of my other clips were shot in Apple Pro Res Log through Filmic Pro. I have about 30 video clips, with 5 of the clips being shot in the native camera in Cinematic Mode. So, I have a bunch of Log footage, with a few clips that have “baked in” color. Is there any way to convert the native footage to Apple Pro Res Log? If not, what is the suggested work around to make these clips look similar? I am editing in Premiere Pro, and would like to have complete control over the color correction and grading. I realize that I can make the log footage look like the native footage, but I really don’t want to do that. I have attached screenshots to show the difference in the footage. Someone please save the day! Thank you!!

No, you can't make the linearized clips into log at this point.

Make sure the auto detect log and auto tonemapping options are both 'on' in Premiere's spiffy new color managment panel. Set the sequence to the color space you want to export in ... Rec.709 (SDR) or HLG (HDR).

Premiere will auto-tonemap the log clips to linear monitor space values, and may come decently close in matching the "straight" clips right off. But if you see a consistent difference, like they're all with black point a bit higher, less/more saturation whatever, you can then create a Lumetri setup where you correct that on one clip. 

Then copy/paste that Lumetri instance on the entire selected group of clips in the bin that need that correction. This is appying a Source correction, a great way to get multiple types of clips closer together.
