Of course I understand that Apple didn't create AVCHD formatting but in all fairness I wouldn't be on these forums if my issue weren't somehow relevant to Apple. To be perfectly honest the process of capturing video to saving the files is pretty straightforward as it is. I capture the footage, insert the SD card, drag/import the files into iPhoto, and then save them as raw .mov files. That's really it. Down the line I can view them, edit them, delete, or whatever.
However, if there is another method that ultimately gets me raw video files that include the capture date, that would be something I would absolutely try. Especially if it involves a currently supported application. What would be even better is if it recognized 60p in addition to 60i as I alluded to earlier.
Why does this all matter to me? Because I'm trying to stay ahead of the next anticipated software shake-up to avoid issues like I had migrating everything from iPhoto to Photos. Literally Apple to Apple. By having these video files available to me in a universal manner, I don't have to worry about reorganizing them down the line. For instance, if you have a Gmail account, it doesn't matter if your ISP is Verizon or Comcast. You'll still have your email just the way you like it.
