Nikon ZR has harsh noise reduction on some codecs compared to the Z6III !

[Aussie Ash]

Philip Bloom ended up purchasing the Nikon ZR mainly because the large screen makes shooting easier.Here are his tests comparing the ZR and Z6III & what are you up to Nikon they aren't the same !

This has been widely discussed before. It's not clear why the h.265 results are so different. Perhaps Nikon has some difficulty keeping the temperature down during long recordings with higher-quality noise-reduction algorithms in the thin body of the ZR? The large screen could also produce more heat. It's obviously something they need to address. Nikon's blotchy high ISO NR algorithms have been a problem since around the D5 generation (in stills) where it is clear that in-camera high ISO NR needs to be turned off (if shooting JPG, and if you use Nikon raw converter, also in that software) to avoid this blotchiness. The files themselves (without high ISO NR) look much better. To my eye the kind of noise reduction the ZR shows in N-Log h.265 look a bit similar to that Nikon used for very high ISO NR in stills. N-Log just brings it out likely mainly due to the user giving less exposure to those videos by following the nominal ISO (800 base ISO in N-Log), so the shadow NR becomes more apparent. Anyway, it's a bit strange Nikon has been silent about this so far.
