Gopro Log Is Too Dark, Here's How To Fix It

Рет қаралды 11,234

Күн бұрын

You might wonder how to color grade or color correct GP-Log. The problem is that no matter how good you are at color grading, the exposure needs to be right in order to get good results. With the release of Gopro hero 12 Black, Gopro also released GP-Log or Gopro Log to the official firmware. But they implemented it with a secret EV comp of -2. This is why GP-Log is too dark in every shot. This video explains why a -2 EV comp is too low, and how to fix it with gopro labs.

Fantastic informative video. It was interesting to learn that GP-Log was simply LOGB=400 + EV Comp = -2. My take: Setting a lower EV Comp can be an okay-ish compromise if you 1) want to preserve highlights (even though it won't look totally fabulous as you point out), or 2) you want to prioritize faster shutter speed for better stabilization (especially in low-contrast low-light environments, like riding singletrack trails in dense forests). But! The key to making that work is to decrease/disable the built-in noise reduction with NR01 and increase the bitrate with BITR. Without those two extra steps, you will just end up with mush, like demonstrated brutally in this video. On a sidenote -- the most recent official Labs release for GP11 (2.12.70/1.10.70) messed up the NR01 setting somewhat, so GoPro has just released some test builds (2.12.71/1.10.71) that seems to have new/different behaviour when using NR01. I might have to get another GP11 or GP12 to make a proper comparison between the old and new modes :)

Amazing video! subscribed! Thanks for taking the time to put it together. I was wondering if I should get the GoPro 12 based on the GPlog, but it looks like I would be better off just getting the 11 and downloading GoPro labs. Any tips on getting the best out of the image with Davinci Resolve Studio? In the past I have used Protune, flat, low sharp and then add some contract, color, sharpening in Davinci.

Find a good LUT that gives you nice results. That's the easiest way to get good results. Learning color grading can take tens of thousands of hours to learn, and IMO it's not worth it if you're just looking for good quality videos for youtube.

I'm getting a lot of questions that I could answer, but decide not to. They are not stupid questions, but they are simple to answer if you just do some simple tests yourself. Compared to the rest of the pipeline of working with log, if you can't test your way the answer, or cannot find the answers to it online (the answers are really easy to find) then using log is not something you should bother with. Going from a log image to an image that is better than what the tone mapping of gopros provide takes a ton of knowledge, and skill, and quite frankly, I've seen very few people manage to achieve a better image than Gopro provides.

GoPro really messed up the GP-LOG and it's going to leave a bad taste in a lot of folks mouths. Perhaps they'll change this down the road. Yes, I had to at least try GP-LOG for myself to know for sure. But, at this point it looks like I'll be downloading the LABS software.

Do you recommend just turning the sharpness down to low or is there something I have to do in GoPro labs? I use footage straight out of camera and I’m using it to vlog. Weirdly, I’ve especially noticed it when I’m using standard color versus vivid or flat. Details on foliage and other inanimate objects looks really beautiful, but peoples faces just look too sharp unless I set the sharpness all the way to lowest. I’m new to GoPro. Any recommendations?

With big cameras we exposure at around +1.7 when shooting log. Isn’t that the case with gopro? Do you just exposure to 0?

@MarkusFinholt 4 ай бұрын

That's an arbitrary number I have no idea how you landed at. We expose to the right with log curves that require it. It all depends on how the dynamic range is allocated compared to the middle gray value of that curve. ETTR is much more complicated than just shooting +1.7 stops. For gopro it's also hard, because it has more stops below middle gray, so exposing very far to the right is going to heavily limit your usable dynamic range. Usually, setting the ev comp to 0 results in optimal exposure for gopros. For snow you might bump it up to +0.5

@leomatis_ 4 ай бұрын

@@MarkusFinholt thanks for the insight! All I know is whenever you shoot log at least on Sony you have overexposure to +1.7-2.0 stops. Everyone recommends that or else you just lose information in the dark areas. Never seen anyone exposure to normal like in 709

So most likely someone with less knowledge on gamma curves made the decision, higher up in Gopro.
