I’m considering getting a Sony a7S III but have read that people are having problems importing and editing the video on computers with it. Apparently it’s not just a matter of dumping the video files off the memory card and start using them but they need to be converted to a format the Mac can read first. Is this correct? I’m on a PC running Windows 10 and aim to edit Sony a7S III 4K video using DaVinci Resolve 17

With this guide, you can smoothly import and edit Sony a7S III 4K recordings in DaVinci Resolve 17, 16, 15 on Windows 10/Mac OS X.

Scanning the specs of Sony a7S III, I know the Sony a7S III produces MP4 files encoded with H.265 or H.264, but it seems DaVinci Resolve 16 does not like the way (XAVC HS, XAVC S-I, XAVC S). The file type is a compressed output format, but not ideal for editing in NLE system. To solve those problems, the quick workaround is to transcode Sony a7S III 4K MP4 files to DaVinci Resolve natively supported format (H.264 Codec .mp4 is highly recommended.).

To complete the task, UFUSoft XAVC Converter for Mac or Windows is recommended, which is a powerful high-quality 4K video converter, player and editor. If you are editing with DaVinci Resolve 16, chances are you already installed this great free utility.
