Panasonic V-Log color correction: V-Gamut to Rec.709 done right

Lumix shooters get one of the nicest log curves in the prosumer world, and one of the most commonly half-converted. Most washed-out V-Log complaints trace to the same mistake: converting the curve and skipping the gamut. Here is the whole picture.

V-Log is two conversions, not one

Like every log format, V-Log flattens the sensor's dynamic range into a gradable file, so straight off the card it looks low-contrast. But Panasonic also records in V-Gamut, a color space substantially wider than Rec.709. A conversion that handles only the curve leaves colors sitting in the wrong primaries: greens lean dull, saturated content never quite lands, and pushing saturation to compensate breaks skin. The correct transform does both legs: V-Log curve to display gamma and V-Gamut to Rec.709 primaries.

Expose for the shadows you want to keep

V-Log places middle gray low, and Lumix sensors reward generous exposure: a stop over the meter is a common working habit, then bring it down in the grade. Shadows that record near the noise floor stay noisy through any correction; highlights in log usually have room to spare. Check with the waveform, not the flat preview.

The correction order that works

1. White balance first, on a gray reference or the vectorscope, while the image is still flat.

2. Convert properly. In Resolve, a Color Space Transform node set to Panasonic V-Gamut / V-Log in, Rec.709 / Gamma 2.4 out, does both legs. A bare "V-Log to Rec.709" LUT may or may not include the gamut step; check what yours claims before trusting it.

3. Set exposure with scopes. Bring your over-exposed footage down until skin sits around 60 to 70 IRE and nothing clips.

4. Match, then look. Multi-cam shoots (a GH body on the gimbal, an S body on sticks) need matching to one neutral baseline before any creative grade, or one LUT produces two different-looking cameras.

The GH vs S wrinkle

GH-line bodies record V-Log L, a reduced-range variant; the S line records full V-Log. Same curve family, same V-Gamut, same workflow, but full V-Log holds more highlight range. If you cut both in one timeline, treat them as two cameras to match, not one.

Or let the boring half run itself

Everything above is measurement, not taste, which is why Basecut automates it: it detects V-Log per clip, applies the full conversion (curve and V-Gamut both, using Panasonic's published primaries), runs a closed-loop white balance and exposure pass, and hands per-clip grades to DaVinci Resolve, all locally on your machine.
