GH4 Optimal Film Setting

There has been some buzz about Michael Medgyesi's experimental GH4 settings that may be worth looking into. Here is the sample video he shot with those settings:


Here is my use of it, this time attached to a Shogun in ProRes HQ 4:2:2 at 30fps.


Downloadable ProRes 422 UHD file available if you want to test out grading.

Maybe asking the wrong person but in Medgyesi's article he mentions a Highlight/Shadow setting of -5/0 but also 0/0.

Is the "zero" setting the norm with the "minus 5" depending on the particular lighting circumstance at the time of shooting?

Re: GH4 Optimal Film Setting

i dunno about taking this seriously...

He goes on bashing flat profiling, but sounds to me like he either went to far with flattening his gh4 and got crap, and/or he just doesn't know a single thing about basic grading. does he know that premade LUTs exist?

And his skintones all appear overexposed, which he mentions is intentional in the article, but i can't recall the last professional that had the opinion of going 80ire+ on skintones unless for a specific style

Yes, I exposed this footage at 60 IRE for skin using the waveform monitor, but I know that Michael prefers using zebras set at 80. I think this stems from an ETTR way of thinking that is all about reducing noise, but possibly at the expense of picture quality. More testing is worthwhile, and it's always interesting to jump out of Cinelike D for a change and try something different.

Of course, if/when Panasonic adds Vlog to the GH4, it's game over for all the other picture styles when it comes to shooting video.

I'm not sure, haven't looking into what his findings were with the 0/0 setting. My video was shot at -5 Highlight, which would make sense giving the shooting scenario of being outside on a sunny (-ish) day.

I wish Highlight/Shadow was connected to the picture profile so I could do a shootout quicker with just changing one setting instead of two. I think the next step is to shoot again with the this and then the typical Cinelike D settings to see a difference.
