#389644 Color Correction of Panasonic GH5 Underwater Footage

Posted by thetrickster on Yesterday, 05:41 AM

Can you manually WB with the recorder?

The White balance is baked in to the ProRes files, so its not like RAW files from a Red or BM camera, so I'm not sure if I'm answering your question below..

 

The GH4 has an issue where if you have a recorder connected and have it in 10bit mode, the ability to manually white balance is removed - so you have to stick with either preset ones (which you could set when in 8bit mode) or using the kelvin ratings or standard 'cloudy' 'tungsten' etc..

 

Luckly the GH5 - you can now manually white balance while you it connected and in 10bit mode.




#389618 GH5 4k 4:2:2 @ 60p recorder monitor

Posted by thetrickster on 22 November 2017 - 09:34 AM

Yeah the newer Inferno and Flame monitors are actually larger than the original Shogun, so don't fit.

 

But I agree, they probably aren't worth the money just to obtain the 4K 60p @ 10bit.

 

Its a fantastic monitor, yes and there maybe an increase image quality (very slight - to none existent) - but it makes your rig massive. I struggle with some boats with mine, as to where to put it.

 

If I didn't have it for the GH4, where there is a good trade off for better image quality and bulk, i think recording internally and using SmallHD type screen would be a better option, but I have it, so not going to waste it - and yes SSDs are cheaper than the V90 cards at the moment, so that saves me from recording internally.




#389398 help deciding with Threaded Filter for UW photography

Posted by thetrickster on 15 November 2017 - 03:52 AM

Hi Sorin

 

If you have a housing for your camera, which can take a filter on the outside (normally 67mm or 77mm) then this filter can be safely removed or attached while underwater. There is normal enough of gap (normally a cutout) for allowing water to pass between the filter and the front of the housing.

 

These same filters (although maybe in smaller diameters) can be used directly on your camera, while its inside the housing, then this becomes an issue as you cannot remove it while diving. You might consider an internally fitted filter, if you are using a dome with your using instead of the flat port.




#389143 WWL-1 questions

Posted by thetrickster on 07 November 2017 - 04:48 AM

The WWL-1 stays in its buoyancy collar, and is stowed in the WWL-1 case that way; just take out the fitted insert.

 

I had not thought of removing the fitted insert for use with the buoyancy collar! Nice!

 

One comment from me in regards to the hard cap. I got a pack of GoPro knock off tethers 

 

2PCs-Pack-Surf-Snowboard-Buckle-Safety-font-b-Tethers-b-font-Strap-with-3M-Sticker-VHB.jpg

 

and stuck one on the front of the cap and fitted a spilt ring to that and then a double ender so can take on the dive and know when I had the camera to the boat guy the lens is protected.




#388944 Panasonic GH-5 lens selection WWL1 or wide-angle

Posted by thetrickster on 01 November 2017 - 08:29 AM

For anyone looking in to going that way bare in mind that the Nauticam gear for the 14-42 PZ will only control zoom and not focus. I dont know if the same is true for the "normal"14-42 II lens

 

There is very few zoom lenses that have both zoom and focus control available, the N85 6" dome has a variant with a focus knob, which I believe will work with the Panasonic 7-14mm and 12-35mm, there is also a number of N85 to N120 adaptors with focus knobs - perhaps others will work with that.

 

I developed and printed a 3D mod for the 14-42PZ nauticam gearing to switch the zoom to focus control - and then on the GH4/GH5 you can use the direction pad to control zoom, so having both.




#388574 Underwater Monitor for Panasonic GH5

Posted by thetrickster on 20 October 2017 - 04:41 AM

The images and video I have seen of the Atomos Shogun looked rather unwieldy.
 

 

I can attest to the fact that the Atomos housings for their 7" monitors make a relatively small rig rather large and yes very unwieldy - BUT stable.

 

The other issue, is as much as I love the Nauticam housings - they are negative as my weight belt, and its not just the size of the housing thats the issue, its the number (and size) of the float arms you need to get the thing neutrally buoyant. Can post photos of my neutrally buoyant rig later, its cost me a lot in buying arms and getting the right mix.

 

I don't regret getting the Flame housing, but the days I take just the camera for some some ambient light shots - I really appreciate the size.

 

The only benefits you will get with running the Atomos is the potential to get 4K 10bit 422 60fps and increased AF speed, but on the other hand, it can't handle the new 6K modes (once you hit record there is no HDMI output) and the cost of SSDs for 4K 60p is something to consider, for the marginal gains.

But boy is that screen a joy to use underwater....




#387981 360 Degree underwater video camera for VR

Posted by thetrickster on 28 September 2017 - 02:09 AM

The main issue is that although they all label themselves 4K - thats 4K of resolution around the whole sphere, not of the current view the user is seeing - which is why this lower end rigs don't provide the clarity or vivid images of the more expensive multi camera rigs.

 

Yeah, will see what happens with the Fusion, as that should be the most supported one that comes to market.




#387977 360 Degree underwater video camera for VR

Posted by thetrickster on 27 September 2017 - 11:17 PM

Can't really help, but I'm currently looking at one for seeing what all the fuss is about so been seeing whats available (cheaply)

 

Kodak SP360 4K - Has underwater housing - but suffers from really bad sitiching underwater.

 

Ricoh Theta V - Just released, has decided underwater (30m) housing and from the example video, it appears there is no visible stitching. I'm off diving next week and if the housing was in-stock anywhere, I would probably of picked one up already.

 

Garim Virb360 - Waterproof (10m?) but suffers from awful sitiching, but has amazing stabilisation and data overlay functions.

 

Today (28th) I believe GoPro will be launching their Hero6 and Fusion cameras officially - and if they announce an underwater housing for the Fusion, that could be the camera to get, due to their proprietary sitiching




#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!

#387595 Winter musings

Posted by thetrickster on 15 September 2017 - 04:50 AM

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




#387184 Panasonic LUMIX GH5 for underwater video

Posted by thetrickster on 01 September 2017 - 01:42 AM

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.




#386069 Panasonic LUMIX GH5 for underwater video

Posted by thetrickster on 22 July 2017 - 11:49 AM

 
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.

#386007 Panasonic LUMIX GH5 for underwater video

Posted by thetrickster on 19 July 2017 - 11:15 PM

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
