Not only a new option, but an option from Nikon themselves. Okay, not exactly Nikon, but RED (owned by Nikon).
REDCINE-X PRO is an intermediary software product that is tasked with handling RED RAW, and now Nikon N-RAW, files. Up to this point, really only Blackmagic Design's DaVinci Resolve could handle files such as the 8K N-RAW the Z8/Z9 produces. DaVinci Resolve is a bit of a kitchen sink though, in that it has ingest, codec, grading, editing, and a host of other features all thrown into it. It's a big learning sink if you haven't been using it before. When the Z9 came out with 8K N-RAW, those that were using Final Cut Pro or Premiere found themselves without any N-RAW support initially, and eventually ended up using DaVinci Resolve, with all the hassles of trying to understand one of the world's most complex software products.
Ironically, RED had the same issue that Nikon faced: if you created RED RAW files, how did you edit them? REDCINE-X PRO was the answer: it allows you to grade and transcode RED RAW (and now Nikon N-RAW) files before sending them to your video editor of choice in a format they understand. That's why I used the term "intermediary" above: REDCINE-X PRO gets added to the workflow process between your ingest and your editing.
What doesn't still seem to be enabled for N-RAW in REDCINE-X PRO is the ability to offload/transfer files from camera to computer directly (i.e. ingest). However, once you have a clip in REDCINE-X PRO there's a lot you can do with it, including frame rate overrides, pixel masking, syncing of audio, and much more than just basic image grading. Typically you'd export your work in Apple ProRes to your video editor of choice afterwards.
Bottom line, Nikon users now have a second free way of dealing with the N-RAW video that they create. If you're interested in more, go to the REDCINE-X PRO documentation page.
Speaking of .NEV files, I've added a new page on this site listing the file extensions for files you can find on your card after using them in a Z System camera.
