GoPro Hero 12 Labs

[DemonViewLLC]

The GoPro Labs firmware is something everyone should be using (imho). Can anyone say if the GoPro Labs Firmware will be available on the Hero 12 on the release date or if it will be a few weeks later (which seems to be the standard). I realize there may be an embargo on information until after the official release date, however it would be good to know if I can still recommend installing this firmware to new owners so they can enter the owner information into the camera.

Working for a synchronous release or as near to as possible. Same day or within a few, not two weeks.

When will Hero12 options be available in the QR code creator?

[dnewman-gpsw]

https://gopro.github.io/labs/control/custom/ is open source, anyone can contribute. I do these updates typically, but lots of other Labs work is taking priority.

I have a few question about the Hero 12 readout modes:

1., In 5.3K / 4K60 LTC gave awesome dynamic range on the Hero 11. It was DOL-HDR readout?

2., Now with the Hero 12 in these resolution/framerates it's advertised as dual readout in HDR mode. Does the extended dynamic range available in GP-LOG mode too? I mean: in log it clips highlights sooner in 5.3K 60fps compared to 5.3K 30fps? Or sensor dual readout is not available while shooting log?

3., How does the GP-Log differs from LOGB=400 at Hero 11?

4., Does all resolution and framerates have 10 bit recording now? For example 2.7K 4:3 60 fps?

5., Will the other (4K/5.3K) 4:3 resolution added back in later firmware?

[dnewman-gpsw]

1. HERO11 only used DOL-HDR in photos.

Tech details beyond the published specs still has to wait a few days. I think Monday or Tuesday all the embargos lift.

[Deadcode85]

I played a little with some footage from DC Rainmaker:
2., No, HDR readout is only available in HDR mode, no extended DR sensor readout in GP-LOG. Shame :)
3. you already answered it in another topic, LOGB400 and GP-LOG is the same, but it seems like the NR is on (or not 1) by default.

[dnewman-gpsw]

3. While HERO12 does use the Labs NR01, it does tune the noise reduction to be more Log friendly. Labs on HERO12 will add full NR01 control.
4. 2.7K is still 8-bit.
5. No idea.

but case is important, mL

What if we set LOGB=400 (using QR control) when shooting in HDR mode?

[dnewman-gpsw]

I tried that, doesn't work like you might hope.

[Deadcode85]

what if you turn off tonemapping for HDR, then LOGB400?

[dnewman-gpsw]

I just tried, mixed results. Potentially it is be using one of the exposures with tone-mapping off, but I'm not sure. The image is much brighter, so more shadows, but clipping highlights, explaining my theory.

[Hydrostreamin]

@dnewman-gpsw awesome. I’ll play around with it some more. Thank you sir!

[dnewman-gpsw]

Labs for HERO12 is out.

[DemonViewLLC]

Excellent! Thank you for letting us know!

[ToddKortte]

The firmware is out, but the code generator is not updated for the Hero12. When can we generate codes with HDR and LOG options?

[dnewman-gpsw]

Just type mL - mode Log or mH - mode HDR, into the Addition Command field.

@dnewman-gpsw

Like this?

I will be making an informative video on gopro log and all of its confusions, plus how to grade with a display or a scene referred workflow. I'd love some answers so I don't spew any misinformation.

• Will GP-Log / LOGB / WIDE / NR01 be available with the Hero 12 and the Max Lens Mod 2.0?

• Is GP-Log only a LOGB=400 transform, or does it include a WIDE=1 to rec709 transform as well?

• It says on Gopro's sites that GP-Log is limited to ISO 400. is this the lower limit, or the upper limit?

• Is there any information anywhere on the gamut size of WIDE=1?

• Is the GP-Log to Rec709 LUT the same as the IDT / ODT from this user? https://github.com/xtremestuff/protune-transforms

I kind of need these answers before I purchase the Hero 12. Thanks as always for the great work.

[dnewman-gpsw]

Yes GP-Log now defaults to 0EV, and with the EV control restored.

In more testing timecode QR Code is working on 1.20.

Labs versions will be out today.

Thanks David,

So this is now effectively LOGB=400 at 0EV which is back to SDR range with the same clipping point as Protune Flat. Bit of a shame as Protune Flat offers more unique bits in the encoding.

[dnewman-gpsw]

Dynamic range hasn't changed. EV is just unlocked, set it to -2 is you want more headroom, or 0EV for more shadow detail. Flat (log113) and no more "unique" bits than Log400.

[RikshaDriver]

Understand DR is the same, however the range allocated to highlights is now reduced to peak at ~2.5 stops. The advantage pre-1.20 f/w had was that this -2EV exposure offset was baked in from the onset - what should have been fixed with this was a +1EV bias correction for exposure metering instead. I will still use -1 or -2 EV with Labs, but there is no difference between Flat and the updated GP-Log as far as the stock firmware is concerned.

Some time ago, I had calculated 10-bit linear input (0-1023) to Flat & GP-Log/LOGB400 outputs respectively and hence the assertion that Flat offers more unique code values (I mentioned bits in haste but was referring to the bit code values): https://www.desmos.com/calculator/smt1hcbs11

From my calculations, Flat provides 546 unique code values whereas LOGB400 provides 475 unique code values... unless the OETF is down sampled from 12-bit linear Input to 10-bit Output or some other calculation method is used, in which case I'm completely wrong.

[dnewman-gpsw]

The same math argument says we get more codewords encoding linear light, and from experience I know how bad an idea that is. Curve emphasis helps with compression and noise in the system. There only linear light encoded in uncompressed systems. Yes, you are also assuming the image pipeline is 10bit, when it is deeper than that.

[mariustoicescu]

Hello, can it be used with GoPro 12 + Max Wide Lens Mod 2.0?

[dnewman-gpsw]

What can be used? Labs support all modes on all cameras since HERO7.

[mariustoicescu]

:)) this is your best answer. Thx for all your help!

[NilsVega]

Hello, can anyone tell me whether gopro labs is better suited for gopro 11 than for gopro 12. It seems to me that several functions of Labs do not work correctly on gopro 12

[dnewman-gpsw]

HERO12 is better as it is newer, except for GPS functions for the H11. Labs gets more updates on the newer cameras. Labs for the HERO13 is best yet.

[NilsVega]

I correctly understood that gopro labs is better for H.11 than H,12

[dnewman-gpsw]

The opposite. HERO12 is better as it is newer, and it has significant robustness improvements (script reliability.) If you need GPS, then definitely get the HERO13, better still. Only reason to get HERO11 today is for the reduced price, but H12 and H13 are the better cameras.
