Came upon incompatibility issues working with Sony RX10 III XAVC S video in Avid Media Composer? If so, you may wish to read this post. It presents a workaround to transcode RX10 III 4K XAVC S files to DNxHD codec for editing in Avid system with optimum performance.
Sony RX10 III is able to capture video recordings in a range of resolutions up to UHD 4K30 as well as high-speed recording in Full HD 1080p at 120 fps. Both 4K and Full HD recording is possible in the 100 Mbps XAVC S format, which is contained within an MP4 wrapper, with 4:2:0 color sampling when recording internally, or 4:2:2 sampling with the use of an optional external recorder via HDMI output.
If you are planning on editing RX10 III XAVC S files in Avid Media Composer, you will find there’s no support for that format in Media Composer. A transcode is required prior to ingest the XAVC S footage into Avid. To process “transcoded editing”, a 3rd party XAVC S Converter app is required. Check a quick guide on how to convert RX10 III XAVC S video to Avid preferred DNxHD.
