N-Log gets less written about it than Sony's or Canon's, which means people often end up applying a generic log conversion to it and wondering why the result sits oddly.
What you are holding
The first question is not the curve, it is the recording.
| Source | Typical | Room to grade |
|---|---|---|
| Internal 10-bit N-Log | Z6 II, Z8, Z9 and later | Good |
| External recorder, ProRes | Older Z-series via HDMI | Best |
| Internal 8-bit | Some older configurations | Limited |
An 8-bit log file has very little room — banding appears in skies and gradients as soon as the conversion stretches contrast back out. If that is what you have, expose carefully and grade lightly, because the range is not there to recover.
This matters more on Nikon than on some other brands simply because of how the bodies evolved, and it is worth checking before blaming the conversion.
The conversion
Nikon publishes an official N-Log to Rec.709 3D LUT, free, on their support site. Use it before anything creative.
The general rules hold, and they are where most results go wrong:
- Convert first, look second. A creative LUT applied straight to log produces the muddy, wrongly-contrasted image people blame on the camera — what is a LUT covers why.
- The conversion is a fixed transform, not a judgement. It is the same for every clip from the same body in the same profile.
- Exposure after, not before. The LUT expects log input.
One clip, then the card
One clip is a minute in any editor — Premiere,
DaVinci Resolve, Final Cut
Pro all import a .cube and apply it.
A card is the real job, and it is not a bigger version of the same one. The conversion is identical for every clip, so doing it forty times by hand adds nothing but the chance of doing it inconsistently. Adjustment layers work when every clip was exposed identically, which is not how a shoot goes once the light moves.
How BatchTone handles it
Drop the folder in, pick the conversion, and every clip takes it. A frame is pulled from each and previewed with it applied, so you are judging your own footage rather than trusting a preview someone else made.
- Per-clip strength for the shots that need less, without touching the rest.
- Audio copied across untouched rather than re-encoded.
- The Mac's own hardware encoder, so a card is not an overnight job.
- Originals never written to.
- 10-bit files from the Z-series read directly.
Same shape on other bodies: C-Log, V-Log, F-Log, S-Log3, D-Log. There is a seven-day trial.
Common questions
Where do I get the Nikon N-Log LUT? Nikon's own support site publishes an official N-Log to Rec.709 3D LUT free. Use it before any creative look.
Is N-Log 8-bit or 10-bit? It depends on the body and how you recorded. Recent Z bodies do 10-bit internally; older setups needed an external recorder. The bit depth decides how much the conversion can stretch without banding.
Why does my N-Log footage band after converting? Almost always 8-bit capture rather than the LUT. The information is not in the file, and no conversion adds it back.
Can I use a generic log conversion? It will look approximately right and not correct. Each manufacturer's curve differs; use Nikon's own.
Should I convert before editing? For more than a few clips, yes. The conversion is the same every time, so doing it once across the folder is both faster and more consistent.
