I bet that the GH4 material could have issues with unique file naming and timecode conflicts. This will get you every time in workflow problems with H.264 DSLR material. We generally advise clients to immediately transcode to ProRes or DNxHD prior to editing, and give the clips non-conflicting timecode numbers so that there's never going to be overlapping names or numbers in the final conform.
DSLRs that restart file names as "0001," "0002," "0003" and so on every day are a nightmare in post. It helps if there's a DIT or a data manager (or an assistant editor) that steps in and changes the file names immediately after they're shot to give them a unique name, like 090318A0001, 090318A0002, and so on, which immediately sorts by date and camera file name.
