Hi, kc_. I'm on Windows, The I-P:5 is Mpeg4 AVCH 264 or, alternatively, AVC, with the former housed in .MOV. Unfortunately .MOV is not a video format, it's a container which can hold videos in different formats, including Olympus' proprietary format, not all of which can--or could--be handled by Premiere Elements. Vondo, above, cites no problems with PE 13, which made me recheck some of the online complaints again. I noticed most were before 2015, so perhaps the difficulty has since been corrected? I hope so,and will tell yall what I find. Thanks for the help and input!
