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!
The A7S III bears a strong resemblance to older a7 series cameras, with one notable exception: a flip-out touchscreen. Users have documented instances of the a7S III overheating and cutting out when recording long 4K videos at higher frame rates in direct sunlight. It wasn’t just the high bitrate 4K codec files that were impressive. The results using the Sony H.265 format were equally impressive, and the HD was stunning too. The Sony a7S III is especially useful for both video and photo shooting.
