HLG vs DLOG Noise and Image Clarity

[rmb]

So as the subject suggests I have been doing some tests. As a pro videographer, I swear by Dlog and Prores. As of recent, I have begun shooting in HLG. To my surprise, HLG seems to provide far more detail as well as some other benefits including being easier to grade.
I am posting here a comparison of a quick 5-second shot where you can see the massive difference in fine detail with HLG vs the same shot in DLOG. My guess is that the standard DLOG is suffering more greatly from the noise issue that has been plaguing prores on the Mavic 3 Cine from the begining.

Anyway, I would love to hear what you other prores folk think.

Thanks,
rb

I will be of no help because the DLOG looks better to me. I do like the way you presented the differences. Well done. Again, no help.

To make a really fair comparison, you have to get the exposure of both exactly the same which will be tough. In your example, the HLG footage is slightly more exposed and this makes the difference you are seeing. I paused your video at four seconds when the wipe (Dlog left - HLG right), was centered over the tree in the foreground. Here you can see that the HLG clip has a higher exposure.

Personally, I like the look of Dlog over HLG as I think it gives a more film-like look but that is a personal preference.

HLG looks good and is definitely easier to grade. I think the look is a personal preference thing but for me, the less time I need to spend in post the better so I prefer HLG.

Moot point anyway when Mini3 has neither

I’m 100% HLG. My post production is always Wide Gamut in FCPX and looks killer on my HDR monitor. And I like the transportability to SDR video displays.

Here’s my unscientific comparison for enhancing detail.

Did you noticed any difference in bitrate? What is the bitrate of dlog and hlg in your files?

Don’t recall. I’ll look it up and get back.

Don’t recall. I’ll look it up and get back.

I noticed that best bitrate is in Dlog and HLG 5.1k over 150. In other settings under 120
