Sony has released an update to Catalyst Browse which now enables full support for XAVC-HS 10-Bit in both 422 and 420 flavours. All that's required is online registration of your camera / serial to make this happen, and it's free of charge.
HEVC is the only way to shoot up to 4K 100fps with audio in-camera [Sony A7SM3] , but unfortunately there's no 100 fps file output in Browse. HEVC is also ideal to preserve quality in Long-Form shoots, but needs good GPU support to make it work, or proxy workflow.
This hasn't really been working for a while now, and it's important to me to see this fixed. Where are we at?
