Gopro13 Gopro Labs Firmware (testing underwater)

[Nando Diver]

 New settings for GoPRO LABS FW (its a work in progress only learn by mistakes made 🫣 ) 

 

information :

Gopro labs extensions

Gopro labs Metadata

Gopro labs discussion forum

Gopro Labs QRcode Generator for IOS

 

 

To reset FW LABS use QRCODE !RESET (then press the shutter three times quickly, this erases all Labs extensions.)

At the moment ive created 3 Profiles with Gopro 13, named in easy way to swap profile underwater.

 

AutoWB HLG HDR  (stock) 

HLG 16:9 4K 60 W

 

WBLOCK  

HLG 16:9 4K 60 W

 

GPLOG WB NATIVE (stock) 

Log 16:9 5.3K 60 W

 

From QRcontrol app ive only use the Extras > Feature FourCC 

Create QRcode with BITR=150 (permanent)  and scan the stock profiles 

Create QRcode with BITR=150 + WBLK=1 and scan the remaining profile 

 

To make sure the correct settings Feature FourCC is applied in the correct profile (ex WBLK=1) after the scan reboot the Gopro and record small 5 seconds clips with different profiles.

Export the original file (not cuts or processing) to the computer and use the Gopro Labs Metadata to verify the metadata.

example: 

WBLK 0 (not applied)

WBLk 1 (applied) 

ps: if the box permanent is selected, the Scan will apply to all profiles.

Heres a video create using profile WB lock (left) and profile AutoWB from Gopro labs firmware

There was strong currents in the diving spot, it was very difficult to maintained the stability while filming.

 

I notice theres minor color adjustments using AutoWB that are imperceptible to the naked eye. 

 

The big advantage of locking the White balance is keeping the same color temperature even if we move the camera where theres no light reflect to the sensor. 

The disadvantege is start filming to far away or to close from the subject and lock the wrong color temperature.

 

The big advantage of using the AutoWB is filming the same stationary scene getting lights reflected back to the sensor.

The disadvantage is pointing the camera from a stationary scene to wide (empty) area with no light reflection and the background water turns blue to green.

 

For me personally im getting more fan of using locked WB profile.

Getting more familiarized with DaVinci Resolve Free Version

 

Here im using DaVinci YRGB color management, HDR, Automatic Mode

Theres some excess of red in second clip, its the reflection of the dive light,  because i was using the profile WB Lock

 

Obviously theres a long way for improvement.

New firmware for Gopro Labs V1.30.70 

 

According to the FW release notes, now there a "new WBDV" white balance for diving, a semi-automatic WB has the scenery get more blue, the more the red channel is Gain up.

 

In my opinion In terms of FW the Gopro is years ahead of the competition.

 

1.30.70 - November 21, 2024

• Added WBDV - White Balance DiVe improvements. Rather than WARM for improving diving white balance, which effects WB the same at all depths, WBDV is more automatic – as the scene get more blue, the more the red channel is gain up. Currently $WBDV=1 is uses =2.33,4.0 internally (gaining red 4x after red gain hits 2.33), so you can try tuning this yourself e.g. $WBDV=2.4,5.0
• Added SHEL - Using $SHEL=1 enables a command shell for Labs over a USB serial port. Every experimental, and looking for feedback. Connect to COM at 115200 8N1. All QR code command work, just type them. Used $ commands will report their data back to the shell, e.g. $BITR or $A or $p:T to read variables.
• Added OPNW - Open Network (allows of faster non-secure http:// vs https:// to be used with Open GoPro)
• Fixed supporting numbers in FourCC codes in Presets (e.g. preset named “DIVE 24HZ”)
• Fixed d1 and d10 for 10-bit selection
• Fixed voice control enabling in Labs

The times ive used Flat color Profile trying to match the Natural Color profile , i never manage to get the colors right in Davinci. 

I just came across this article about Gopro Natural Color VS  Flat color, its worth to read it :

 

A note about Flat Color vs Natural Color

LTM/GTM not Present in Flat Color
Flat color profile doesn’t have any of GoPro’s LTM or GTM applied. LTM being Local Tone Mapping, which is a process that enhances the contrast between objects across the whole image (think clarity filter in Lightroom). GTM is Global Tone Mapping, which is a means of boosting shadows and bringing down highlights. The picture in Natural Color has been redesigned from the ground up and actually starts with a very underexposed image so that it can do a very good job retaining highlights once GTM is applied under the hood. If you compare Natural against Flat, you likely won’t be able to get the same amount of highlight saving even after rigorous color correction. This brings me to my second note: 

Dynamic Range With Flat Color Profile
After extensive testing, I haven’t been able to reproduce quite the same amount of dynamic range when shooting Flat Color as I’m able to get with Natural Color. This is due to the GTM process in the image pipeline that happens under the hood as a sort of faux HDR process. This isn’t to say you can’t shoot in Flat Profile, but a watch-out if you want to get the most range out of the box. It’s also a testament to the advanced algorithms found in HERO11. 

Custom Log Curves with Labs
For those interested in digging a little deeper, HERO11 and Mini offer the ability to load custom log curves when shooting Flat Color using GoPro Labs. Flat Color is in-fact a type of log curve, but if you wish to match log curves from other camera sources, you can load those onto the camera. Something to note is that loading a flatter log profile won’t get you more dynamic range out of the camera, it will just change around how the shadows and highlights are displayed. Good news is that 10-Bit color helps quite a bit when shooting in Flat color since the gradations in colors are so similar.
