Panasonic's log is straightforward once you know which of the two you shot, and the difference is easy to miss because the menu calls both of them V-Log.
V-Log or V-Log L
| V-Log | V-Log L | |
|---|---|---|
| Bodies | Varicam, S-series, box cameras | GH5, GH5S, GH6 and similar |
| Dynamic range | Full | Reduced |
| Shadow noise | Lower | Higher, especially pushed |
| Conversion | Panasonic's V-Log LUT | The V-Log L variant |
V-Log L is the version on the Micro Four Thirds bodies, and it was designed around a smaller sensor with less range to give away. Using the full V-Log conversion on V-Log L footage lifts the shadows too far and makes noise that was manageable look like a problem.
Check the body, not the menu label.
Why it needs converting at all
Log is a container, not a look. It stores a wide brightness range in a flat, desaturated, low-contrast image so highlight and shadow survive to the grade, and viewed directly it looks washed out and slightly milky.
That is the format doing its job — what is a LUT covers why getting back to something viewable is a fixed transform rather than a taste decision.
The conversion
Panasonic publishes official V-Log to Rec.709 LUTs, free, and they are the right starting point. Points worth knowing:
- Convert first, look second. A creative LUT stacked straight onto log gives the muddy result people blame on the camera.
- Expose V-Log a little bright. It is common practice on these bodies because the shadows are the weak part, and it means your conversion may need pulling down slightly rather than up.
- Check your gamut if the body offers V-Gamut versus a smaller space; the conversion assumes one.
One clip, then forty
For one clip any editor does this: apply the conversion LUT, then set exposure — in that order, because the LUT expects log input. Premiere, DaVinci Resolve and Final Cut Pro each have their own route to the same thing.
Forty clips is a different problem. The conversion is identical every time — the same camera, the same profile, the same transform — so repeating it by hand buys nothing and introduces drift. Adjustment layers help when every clip was exposed the same way, which on a real shoot is rarely true.
How BatchTone handles it
Drop the folder in, pick V-Log or V-Log L, and every clip takes the conversion. A frame is pulled from each and previewed with it applied, so the judgement happens on your own footage.
- The clips that need less get a strength slider; the rest stay put.
- Audio is copied across untouched rather than re-encoded.
- The Mac's own hardware encoder does the work, so a card is not an overnight job.
- Originals are never written to.
- 10-bit footage from the GH5 and GH6 is read directly.
Same shape of problem on other bodies: S-Log3 for Sony, C-Log for Canon, D-Log for DJI. There is a seven-day trial.
Common questions
Is V-Log L the same as V-Log? No. V-Log L is the reduced-range version on the GH-series, with its own conversion. Using the full V-Log LUT on it lifts shadows too far.
Where do I get Panasonic's V-Log LUT? Panasonic publishes them free on their support site, per profile. Use theirs before any third-party creative LUT.
Should I expose V-Log to the right? Slightly bright is common practice on these bodies because the shadows are the weak part. It means pulling down after conversion rather than lifting.
Why is my converted footage noisy? Usually a full V-Log conversion on V-Log L footage, or underexposure. Log is unforgiving about the second.
Can I batch this in my editor? With an adjustment layer, when every clip was exposed identically. The moment they were not, you are unpicking it clip by clip.
