V-Log to Rec.709

V-Log is Panasonic’s log format across the GH and S series, and it is one of the better-behaved ones: a gentle curve, a clean noise floor, and colour that holds together once it is decoded properly.

What a correct V-Log conversion does

A correct conversion inverts the V-Log curve and applies a V-Gamut to Rec.709 matrix. V-Gamut is wider than Rec.709, so skipping the matrix leaves greens especially over-cooked — the giveaway on foliage-heavy footage graded with a curve-only LUT.

Both halves live inside the .cube you download, so the conversion cannot be forgotten, applied twice, or stacked in the wrong order — the three ways log grades usually go wrong.

The mistake to avoid

Treating V-Log’s flat contrast as “needs more saturation”. The saturation is there; it arrives when the gamut conversion happens, and adding it beforehand doubles up.

Using V-Log with any pack

No pack here is authored specifically against V-Log footage, but every grade in the library can carry its conversion: choose V-Log as the footage type in the LUT Library and the decode is written into whichever .cube you download. If you want a starting point, the free conversions show what a neutral decode should look like.

Common questions

Why does my V-Log footage look grey and washed out?+

Because it has not been decoded yet. V-Log stores far more dynamic range than a normal picture profile by recording a flat, low-contrast signal — that is the point of it. A conversion to Rec.709 maps it back to an image meant to be looked at.

Do I need a separate conversion LUT and then a creative LUT?+

Not here. Pick V-Log as your footage type before you download and the V-Log → Rec.709 conversion is baked into the same .cube as the look, so it is one node in Resolve or one adjustment layer in Premiere.

Which cameras record V-Log?+

Panasonic GH, S series. If your camera records V-Log, these conversions apply to it.

Which LUTs can I use with V-Log?+

All 175 grades in the library can bake a V-Log conversion in — choose V-Log as the footage type before downloading and it is written into the .cube. The free conversions at https://ireelz.com/luts/free are authored for specific cameras, so use those if you shoot one of them.
