LUTs for using WIDE with Log 400 (GP-Log), Log 113 (Protune Flat) and Native/Vibrant stock profiles.

The Labs feature WIDE is for a wider color gamut, awesome, until you want to match the look of stock GoPro footage. These LUT help convert the GoPro wide gamut to Rec709 color.

WIDE_Flat_2_709_Flat.cube - Converts WIDE shot with Protune Flat to Flat with Rec709 color (preserves the curve.)
WIDE_Flat_to_Rec709.cube - Converts WIDE shot with Protune Flat to Rec709 transfer function and color.
WIDE_LOG400_to_709_LOG400.cube - Converts WIDE shots with GPLog/LOGB=400 to Rec709 color (preserves the curve.)
WIDE_LOG400_to_Rec709.cube - Converts WIDE shot with GPLog/LOGB=400 to Rec709 transfer function and color.
WIDE_Natural_to_Rec709.cube - Converts WIDE shot Natural/Vibrant to Rec709 color (preserves the curve.)

thank you so much!!! amazing!!! :)

Is there any technical info on what type of tone mapping curve is applied?

[dnewman-gpsw]

No, and I'm sure that is internal IP. GTM and LTM are scene dependent and dynamic, hard/impossible to emulate with just LITs.

[lyricsdude]

is WIDE exactly the same on Gopro 11 and 12? or there might be slight differences in some colors? On which one these LUTs work best?

[dnewman-gpsw]

It is exactly the same sensor. If you select Flat with WIDE=1, they should be effectively identical. The LUTs are each designed to match the in-camera options you select.

[lyricsdude]

thank you. I currently have the Gopro 11. Is there any reason to upgrade to the Gopro 12 when I use Gopro Labs?

Hi, would you mind releasing LUTs that convert to Davinci Intermediate Gamma & Gamut please? Specifically i would need WIDE shot with GPLog/LOGB=400 to Davinci. I would like to heavily grade my footage in Davinci Resolve and i am confused how i should work with these LUTs otherwise. Use the Rec709 LUT at the end of my grade and use incorrect grading controls for given Gamma/Gamut before (since Davinci does not know either logb400 Gamma or Hero11 sensor native gamut) OR use the Rec709 LUT before the color grade which would probably be limiting for the end result.

[dnewman-gpsw]

I'm sure they exist already. Third parties have created IDTs for GP-Log and Labs WIDE LOGB modes.

One example (which I have never used) https://xtremestuff.net/gp-tune-transform-manual/

[LeonardSander]

Well gp tune is the only option i found that supports wide/logb400 to davinci. And i don't necessarily want to pay for it😅

I have a technical question, why in wide=1 the red color is not true i.e. too orange, no Lut changes this, while trying to restore the correct red color spoils the skin color, what is the explanation for this?, I get the impression that "wide" and skin color is a bumpy road.

[Pax709]

This is a demonstration of the superiority of the wide 1 mode with the Natural file, not much can be done to match it on the right. Is the only difference between wide 1 and rec the colors other than gamut sRgb, or is there more to it than that?

[dnewman-gpsw]

No idea how this shows that. WIDE=1 just turns off the color matrix, that is literally it.

[Pax709]

And what is the idea of using WIDE1 mode to profile Natural and then converting to Rec709, what do we gain?

[dnewman-gpsw]

Options. You can do it. And you get to control how a color saturates.

[Pax709]

You're right, that's why with your Lut we get better colors after conversion to REC709, hence the better color contrast, I don't know if I'm calling it right.
