Just got the Sony a7S III and I can't seem to open the 4K MP4 or even successfully transcode the video files into something that can be read on the mac. I downloaded an video transcoding software and it doesn't works. I can't preview the video in Final Cut Pro X. Very frustrated here, any advice? Thanks!
