#387631 Color Correction of Panasonic GH5 Underwater Footage

Posted by thetrickster on 16 September 2017 - 05:04 AM

I'm really impressed that most of the shots was with AutoWB and they corrected all okay! Makes using MWB a bit of a non issue - one less thing to fiddle with.

And oh boy are you shark shots tack sharp! (How were you running the camera? Do you know the aperture?) super impressed!!

The biggest thing I found wasn't 10Bit or 8bit or even the 60/30. But the compression. Using the atomos recorders with 880Mbps, when you start pulling the channels around the macro blocking (or rather the lack of compared to the GH4 100Mbps) really makes a difference, so I could see the benefit with the 400Mpbs options Internally on the GH5 without the need for 4kg+ of a atomos housing.

Look forward to see your finished video of your trip - not sure I want to get that close to Bulls sharks!

Looks like they missed the boat on that one - shame...and surprised!

 

Well at least it makes me feel a bit warm inside, sticking with the GH4/5 as I was almost tempted by a AX100 previously

Apart from the 60fps 422 10bit, makes external recorders like my Inferno, completely redundant.

 

Good play Panasonic, impressed.




#386556 Lens question

Posted by thetrickster on 07 August 2017 - 11:24 PM

My first thought would be the Panasonic 7-14mm in the 6" dome, as the sensor in the BMPCC is slightly smaller than a m43's so you want to try and gain back some of the crop lost.

In your below-20 dives, with magic filters on, how does MWB behave in shallow waters (begining or ending the dive) ?
I guess you have the filter fixed on the lense


I remove the filters if my intended dive site is below 20m and use normal lights and get closer.

Which are mounted internally. So it's fixed decision before the dive.

My GH5 will be with me on Weds, (couldn't refuse at the moment with the Euro being strong against the £ and Panasonic UK doing a £100 trade in offer. I got the body for 1495€ delivered ) alas with that and the CYAN Leds. I'm spent. So the NA-GH5 will have to wait a couple of months.

I have to admit the new Atomos screens (in the Flame and Inferno units) are to die for underwater, ultra bright and sharp and using the RGB parade, I can manually adjust the WB using Kelvin instead of using slates while eyeing the Red channel.

 

BUT, and having spent a small fortune on one and all the bits to outfit my GH4, the viewing position is no way as good as the Dive and See and other 5" screens -  I've had to modify (and still need to finish off) the way it fits on the handles to get the handles further back and the screen further forward, as the screen is just way too close to your face in the standard configuration - and I think my eyesight is going!

 

Looking forward to at some point towards the end of this year, upgrading to the GH5 and the better ergo of the NA-GH5 (still on the NA-GH3).




#384601 Panasonic GH-5 lens selection WWL1 or wide-angle

Posted by thetrickster on 01 June 2017 - 01:13 AM

Dont want to open a new thread so i ll post my question here.

I am thinking to make the move from a compact camera to the GH5.

Considering that it will be used 90% for video, mostly for wide angle with the occasional macro stuff and that i already own the WWL 1 and CMC 1 what would be your lens choice?

 

Thanks!

 

If you have the WWL-1 and CMC-1 already I would get the 14-42mm II or 14-42mm PZ and the flat port and go from there.

 

I'm really happy with my current setup with those wet lenses and my GH4and 14-42mm




#383955 Are you shooting 30-50-60 FPS?

Posted by thetrickster on 10 May 2017 - 07:56 AM

Its a really good question, and one which I find intriguing due to the recent onslaught of 4K@60p

 

Most of my cameras I've had, were limited to 25/30p in 1080 - so never really have actually shot much on my GH3 and GH4 at 1080p60 - i think the lure of UHD sort of spoiled the benefits of shooting 1080p60, and even now I'm hard pressed not to like my 30p stuff.

 

As the guys have said above, and from recent videos, underwater footage shot at 60p and played back at 30p - looks lovely. For me, its not that it looks 'slow mo' but that you get to appreciate the coral scenes more, the fish aren't so jumping around, the movement of the soft coral is more smooth and for sharks and the like, they look so much more defined slightly slowed down - yet you feel like the movement is still normal. On the other side, playing 60p back at 60p to me, looks awful from the youtube stuff I've watched - too real, too jerky and doesn't lead it self to storytelling - so for delivery to youtube etc I would still upload at 30p

 

I'm still shooting 30p at UHD, but instead of upgrading this summer, I'm going back down to 1080p and having a look at what my stuff looks like 2x slowed down.

 

As to WB - if I'm using lights, the WB is set to the Kelvin of the lights, or if not I'm Manual White Balance every few meters.

Might have my hands on a GH5 (no housing though!) for the weekend. Any tests I should do that haven't been covered by everyone else on YT?

Can we assign one of the Fn buttons to do TRUE one-touch WB ?

 

Got another questions, but forgotten at present - will edit post once I remember.




#381371 Custom white balance and noise

Posted by thetrickster on 09 February 2017 - 09:59 AM

White or Grey. It doesn't really matter. The key is to have something that has no colour cast (so have the same about of Red, Green and Blue)

I have a WB slate which has actually a slight blue/green cast so making the camera over compensate a little towards red.

But anything Matt white or grey is a great start

Here are the GH5 overlaid (in Red) the GH4 - as you can see the GH5 is quite a bit different in all aspects

Posted by thetrickster on 02 February 2017 - 10:26 AM

Oh and btw, would all/most of the buttons work on the gh5 in a gh4 nauticam housing?


The housing door won't even close if you tried the GH5 in the GH4 housing (if we are talking Nauticam) as the GH5 is thicker (and about 10% more in volume)

Well not per say for the GH5. This housing of their is a generic (hence the size) MIL housing that takes, GHx cameras, A6300/6500 etc.

They are somehow using wifi for the controls (the buttons on the right)
