I have an M1 macbook, and an iphone 13. Thanks for instructions I think you are right I have to do a specific flow so the HDR isnt lost ie in software like CapnCut I suppose. Thanks again for the help m so glad Ive slowly figured this out with ur help.
yep, plenty of software will export in non-HDR and lose the information. some software (i.e. iMovie, Final Cut Pro, DaVinci Resolve) won't lose the information when configured correctly, but HDR workflow is always a bit different than SDR.
