Gopro 13 VS insta360 Ace Pro 2 VS DJI Osmo Action 5 PRO vs Iphone 16pro Max Part 2 by Matthias Lebo

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. .

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.

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.

Ignore the above comments (can't edit anymore) ive had some help in GitHub forum and looks like ive messed up the QRCODE. Need to try WBLK=1 in the next Dive.

Here's two videos comparing the Profile HLG HDR left VS QRcode Generated right (NO GRADING) Hypersmooth - Autoboost video LEFT seems more stable than ON video RIGHT Generating a QR code with same settings and applying Dive=1 + Wide =1 + BITR= 150 it seems it also affects the other profiles. Dont see any differences in color, and the Bit rate jump for 120Mbit/s (stock FW) to 144Mbit/s (Gopro labs FW in all profiles including the GP-LOG profile The profile GP-LOG is 8-bit, SDR and the color space BT.709

Gopro labs (optional testing) yesterday ive tried this settings WBLK=1 don't really lock the white balance, its noticeable a change from blue to green/blue Warm=x i set red to 60….it was too much Cool=x i set the blue to 20, doesn’t make a big difference from using Auto WB…but could be handy to reduce the excess of blue at red sea for example. WBLK=1 This is an auto lock for balance, it auto white balances until the capture starts. The feature was added for scuba users, as fixed white balance are computed for above water, and while the auto works great in dive scenarios, some prefer a fix white balance per clip. WARM=x - WARM maybe useful with DIVE, so you can improve the red respond for deeper dives. x range -50 to 100. Reducing or increasing red signal only. COOL=x - COOL maybe useful with DIVE, so you can decrease the blue respond for deeper dives. x range -50 to 100. Reducing or increasing blue signal only.

It seems using HLG HDR some Presets don't change, like ISO to 800 (ISO 1600 is mandatory). ive select WIDE=1 because it seems is using a wider gamut according with what the sensor captures, even using AUTO WB. Gopro Labs Settings for the 13 Video Mode preset HDR 4K 60FPS Lens WIDE EIS Autoboost PROTUNE depth 10-bit bit rate high shutter Auto 0EV Auto WB ISO min 100 ISO max 1600 sharpness medium color natural PREFS Auto off never lcd off never QR CODE DIVE=1 - optimizing the Hypersmooth stabilization for underwater. WIDE=1 This offers a color gamut like setting white balance to Native (wider gamut), while enabling auto whitebalance, or user controlled whitebalance. With WIDE off (0 - the default), the camera saturates color to the Rec709 gamut (basically sRGB), so some extreme real-world color saturations are clipped by the gamut. With WIDE=1, the gamut is sensor native, not Rec709, not Rec2020, just what the sensor sees. BITR=150 - set the compression in Mb/s for the Protune High Bitrate setting (HEVC only). Normally this would be around 100Mb/s, however higher (or lower) rates may be achieved with newer SD Cards. No guaranteed capture reliability using this feature. Input range in Mb/s from 2 to 200. Counterintuitively, lower frame rates like 24/25/30fps can use higher bitrates than faster frame rates. e.g. A camera that is reliable doing 180Mb/s at 24fps, will likely need to drop to 150Mb/s for 120fps. Most GP2 cameras can do 150Mb/s for all video modes, but your testing is still required. Use at your own risk.

In my opinion all the 3 actions cameras for underwater are very close to each other, the iPhone runs in different league. OA5 PRO - the temperature sensor and depth sensor dont work inside the underwater case, its the best camera for snorkeling, its the worse for scuba diving due the Vignette in the corners and low bitrate. ACE PRO 2 - Its "almost" the best for Scuba diving, support 8K30 not 8K60, support 8bit not 10bit, largest sensor for better low light conditions, dedicated preset button for specific setting underwater, dedicated underwater mode, and dual AI sensor. GOPRO13 - Support firmware Gopro Labs to squeeze the maximal potencial of the Hardware , support HLG HDR, best with 3rd party acessories for different types of wet lens. iPhone 16pro max - the only one that allow to modify all the settings underwater, supports HDR, but unfortunately it doesn't have SDCARD and to transfers raw file requires more steps , the image stabilisation is the worse overall, its 3x more expensive.

The Gopro13 White Balance makes a good job getting the right colors depending of the information captured by the sensor. In my opinion, If theres light reflected to the sensor, the colors can be accurate, if theres no lights reflected the Algorithm works with what he has.. When theres a change in Temperature/kelvin (light reflected ) the Gopro sensor acts accordingly to his algorithm. See the exemple below with no color grading The water is Blue in the background when im close to some object The water is Green when there no light reflect to the sensor The water is Blue in the background when im close to some object again.
