Axel, that is ridiculously helpful, thank you. I edit with Premiere, which happily* gobbles up the 10-bit files these days, so I can manage to edit them in the end. It's just hard to sort through footage before I import. I was thinking of using Adobe Media Encoder to transcode everything to ProRes LT (which is around the same bitrate as the in-camera codec—perhaps a little bit higher), but now that I understand that the problem is bit depth and not anything else about the codec, that transcoding step might not be my friend. If I have to transcode from 10 bits to 8 bits, I am giving up bit depth, even if I keep overall bitrate constant. The question is whether I will really feel that difference when grading difficult shots or in final picture quality, since realistically my delivery will always be Vimeo or YouTube anyway. I suppose the final answer, barring changes to my workflow, is to wait till Finder supports 10-bit files! (For posterity, here is a link to an Apple support forum confirming the 10-bit limitation.) *As happily as it does anything! It likes to crash, and I am editing on an underpowered machine for this footage for sure. Ultimately proxies FTW, but that's later in the workflow.

Absolutely searched before posting. Did not find that post. Thanks!

Some of the files I shoot on my GH5 can be previewed in Mac OSX Finder, and some cannot. Specifically, if I shoot 2160p24 (4:2:2, 10-bit, Long GOP), Finder is not pleased, and if I shoot 2180p60 (4:2:0, 8-bit, Long GOP), Finder is pleased. Looking at the metadata of the Quicktime files, I they both claim to be H.264, but Finder treats them differently. I can preview the 24p files in VLC, but it's a bit of a workflow bummer. I like to tag files in Finder, but can't for 24fps footage. I'm not looking for a fix here, but does anyone have any insight into why this is so? These are all H.264 Long GOP files, right?
