If you are looking for a way to import and edit Sony RX100 IV 4K XAVC S video in FCP X smoothly, you may wish to read this thread. It displays a workaround to transcode Sony RX100 IV 4K XAVC S video to ProRes 422 for use in FCP X natively with optimum performance.
Needed a workable Sony 4K XAVC S Converter for Mac
“Hi, there, I use Sony RX100 IV for video, and just look for a helpful converter to transcode its 4K XAVC S media for use in FCP X easily and directly. Does anyone know a good converter to do this in batch? Thanks a lot for any help.”
The Sony Cyber-shot RX100 IV offers a 1-inch, 20-megapixel sensor like the RX100 III, but it uses a different technology dubbed “stacked CMOS sensor” and branded Exmor RS. One of the most impressive features of the RX100 IV is its ability to capture and record 4K video, in camera, using the XAVC S codec. This is accomplished with full pixel readout without the need for binning. Video record time when shooting 4K is limited to 5 minutes, though. The RX100 IV can also record (up to) 40x super slow motion video (not in 4K mind you), at 960fps, 480fps and 240fps.
The 4K (QFHD 3,840×2,160 pixels) footage delivers much clearer image, but may also cause incompatibility issues while editing in FCP X. To be able to work with RX100 IV XAVC S 4K video in FCP X stably and reliably, we would recommend transcoding RX100 IV 4K XAVC S footage to ProRes 422 for use in FCP X smoothly. This requires third party software like HD Video Converter for Mac. Read on to find a step-by-step guide talking about how to transcode RX100 IV 4K footage to ProRes .mov format for working in FCP X natively without extra rendering.
[Guide] How to convert Sony RX100 IV XAVC S 4K video to FCP X’s editable ProRes codec?
Download, install and run HD Video Converter for Mac, then follow these steps:
Step 1: Run HD Video Converter for Mac as a professional RX100 IV XAVC S 4K video to ProRes Converter. When its main interface comes up, click ‘Add File’ to load source video to it.
Step 2: Select ‘Apple ProRes 422 (*.mov)’ as output format for opening with FCP X
From the ‘Profile’ list, move to ‘Final Cut Pro’ catalogue, and select ‘Apple ProRes 422 (*.mov)’ as target format. Apple ProRes is the best suited editing codec for FCP X and its former version FCP 6 and FCP 7. When loading them into FCP X/6/7, you needn’t wait for a long time for rendering.
Important: If you’ve loaded a number of video clips to do batch conversion, please do remember ticking off ‘Apply to All’ option before you start.
Step 3: Adjust video and audio settings (for advanced users)
If necessary, you can click ‘Settings’ button and go to ‘Profiles Settings’ panel to modify video and audio settings like video encoder, resolution, video bit rate, frame rate, aspect ratio, audio encoder, sample rate, audio bit rate, and audio channels. 3D settings are also available.
Step 4: Click ‘Convert’ to start Sony RX100 IV XAVC S 4K video to ProRes MOV conversion.
Step 5: Click ‘Open Folder’ to get generated ProRes 422 QuickTime files for transferring and editing in Final Cut Pro X with optimum performance.
