Run into issues importing Sony AX33 XAVC-S 4K footage to Avid for further editing? If so, you may wish to read this post. It displays a workaround to transcode Sony AX33 XAVC-S 4K video to DNxHD .mov format for use in Avid Media Composer with optimum performance.
Sony’s FDR-AX33 Handycam Camcorder records 4K and HD movies in the XAVC S format, which uses MPEG-4 AVC/H.264 for video compression and linear PCM for audio compression, while saving files in a MP4 wrapper which allows for extensive record times and easy editing. The FDR-AX33 captures the finest details in 4k (QFHD: 3840 x 2160), 4x Full HD resolution. The XAVC S codec and incredibly high resolution produces vibrant and extremely realistic images. What’s more, the blazingly fast image processor is the same one employed in professional Sony models, making it possible to record 30p movies in 4K and 60p in Full HD 1080 resolution for incredibly smooth and sharp playback, with no loss in realism, even when panning the camera and shooting moving subjects.
XAVC-S codec delivers stunning 4K and HD recordings, but lots of consumers complained that they couldn’t work with Sony AX33 XAVC-S 4K/HD movies in Avid Media Composer smoothly. Is there a possibility to fix the incompatibility issues? Yes, there is. Our suggestion is “convert them” first. That means you convert Sony AX33 (4K/HD) XAVC-S footage to a format (e.g. DNxHD) that is suitable for editing in Avid system first, and then import them to your editing program for post production. This is called “transcoded editing”. HD Video Converter will do the trick.
You can download a demo version (for both, PC and Mac) to have a try. They are not free but it is totally worth it.
