Samsung NX1 H.265 video to iMovie Workflow
        
        Samsung has been pretty inventive in the digital camera world. The NX1 sits in a crowded field of excellent cameras - both DSLR and mirrorless - such as the Nikon D7200, Canon EOS 7D Mark II, Panasonic DMC-GH4 and Fujifilm X-T1. Ironically, the only major complaint we had about the NX1's video was that it was a bit too forward looking: it relied on the advanced H.265 codec, something that many computers and editing systems are just now beginning to handle well.
        
        After   recording some stunning 4K footage by Samsung NX1, chances are you   want to edit these 4K videos in iMovie so as to make them more   stylish, before uploading to YouTube or posting on Facebook. However,   here comes the problem, the recorded MP4 files are compressed using   the H.265 codec, which is final delivery codec and it is not one you   want to use for editing.
