Atomos has released a new 10.66.1 firmware update for their Ninja V fixing an issue with ProRes RAW recording from some Sony cameras.

And although this firmware update doesn’t add new features or functionality, it is rather important as it fixes a metadata bug with ProRes RAW files in Final Cut Pro. This bug causes RAW footage to appear heavily underexposed. 

Details for AtomOS v10.66.1 Firmware Update

  • Fixed an issue with ProRes RAW files from:
    • Sony alpha 1 
    • Sony A7S III
    • Sony FX3 
  • The ProRes RAW issue is as follows:
    • Some footage appears underexposed by 3 stops in Final Cut Pro and in playback mode on the Ninja V.
    • This is due to a metadata issue; the video data is unaffected and recoverable during post–processing.
