Transcoding camera footage to Apple ProRes codec is necessary if FCP X won’t work with your Sony a7s II 4K video smoothly. Because ProRes codec provides better performance during editing, faster render times, and better color quality for compositing. This guide teaches you the basics of how to convert Sony a7s II 4K video to ProRes codec for FCP X editing.
Why do we need to re-encode/transcode Sony a7s II 4K XAVC S .mp4 files to ProRes before editing in FCP X?
Sony’s a7s II camera is a great option if 4K video is your thing. The a7s II can record 4K 4:2:0 8-bit video in XAVC S format with no pixel binning to a suitably fast memory card. In theory, FCP X has good ability to deal with Sony a7s II 4K video. However, users still have issues one or another in practical cases, such as incompatibility issues, choppy/laggy issues and much more.
This happens paticularly when you use a slow Mac machine, or work with Final Cut Pro X version 10.1.4 or earlier. Keep in mind that 4K XAVC S footage is CPU intensive, you will need to transcode to ProRes first for a smooth workflow if your computer is not as fast as it requires. That’s the main reason why you need to transcode Sony a7s II 4K XAVC S to ProRes before editing in FCP X. More than FCP X, the ProRes codec is also well supported by other Mac based NLEs like iMovie, Adobe Premiere Pro, and DaVinci Resolve.
Transcoding can seem a little daunting at first, but once you install the right tool you’ll be able to re-encode a7s II 4K video files to fit your needs easily. We walk you through how to encode Sony a7s II 4K XAVC S video to ProRes for editing in FCP X fluidly in the guide below:
