Grading GH4 V-Log

Recently Driftwood Productions was kind (or is that cruel) enough to share (rub our noses) in some clips from their production, Swim to Land, shot on the Panasonic GH4 utilizing a beta version of the V-LOG profile.

While it would be foolish to jump to conclusions based on two short clips shot under the same conditions, I’m having a hard time holding back my enthusiasm for what I’m seeing. V-LOG is nothing like the broken “CINE” profiles we’ve all been trying to push.

I did some extremely quick, global adjustments using my go-to tools for extremely quick, global adjustments: FilmConvert and Finisher. Results below. (Click to link to full resolution uncompressed PNG’s.)

EDIT: I almost forgot, here’s what my final grade would look like (from stacking the two above.)

EDIT 2: Can’t resist playing with this. Here’s a very aggressive “day for night” grade:


Part of the reasons these clips hold up so well to grading is that they were recorded @ 4:2:2 10bit on an Atomos Shogun, but I suspect that internally recorded 4:2:0 8-bit clips will hold their own, too.

With every new day, and every new “leak”, it seems more likely that Panasonic will release V-LOG for the GH4.

Soon, please.

    Really nice results Joe! Lets hope it’s not to much longer. Jordan over at “The Camera Store” as been using it for some time now and getting pretty amazing results as well.

      Looking at their videos is interesting because you can see the progression in learning to best work with LOG footage. Expect an onslaught of overly flat, dreary footage when V-LOG first hits. As shooters get more experience with it, you’ll see color and contrast return to their grades.

    Driftwood did release a quick clip that was shot internal I would check his twitter account. Also I cant wait for this either as we shoot tons of shots outside and this would help us tremendously on our shoots. These guys are kinda dragging their feet but they would have to give him permission to release those files so it should be soon… i hope.

    Thanks for the great info you are sharing on the GH4. There is one thing that disturbs me about this camera on certain shots, which is an exaggerated amount of in-built sharpening even though its set to the -5 setting and i.Resolution is set to Off. Aliasing and “jumping lines” are easily seen when filming houses and other objects with straight lines.

    Do you have any tips on further reducing the sharpening?

    Im shooting in 4K but downscale to 1080p in Premiere. I also shoot with the 12-35 f/2.8 OIS which I hear might add digital sharpening as well. (Already spent a 1000 bucks on that one so cant afford to change to Speed Booster and primes….)

      Three thoughts:

      1. The lens can’t add “digital sharpening”. That’s not possible, that happens in electronics *after* the sensor. But modern m43 lenses are typically very sharp, and clinically accurate, which many people do not find pleasing.

      2. Are the artifacts visible when you view the footage 1:1? I’ve shot a lot with this camera, and never seen such artifacts. Makes me question if the artifacts come from Premiere’s scaling.

      3. There are several different filters available that can help soften your image in pleasing ways. The Tiffen satin filters, in particular, come to mind. I bet you’d be pleased with what they do to 4K images. (I have the black pro mist filter, which I use for almost any sort of “beauty” shot.)
