GH4 4K setting

Hi dear all,

Please kindly advice me regarding these question:

1.Which 4K file format you prefer to film 4K? MP4(LPCM) or MOV ? What is the big diferent between?

2. Regarding Ninja 2 connected with GH4, Ninja 2 only support GH4 with setting as AVCHD(FHD/17M50i), to allow video signal to appear on Ninja 2 monitor. Otherthan that ,the Ninja 2 monitor just appear black, withGH4 video file format setting as MP4,MP4(LPCM),MOV, is that right?

3. I can only use Ninja 2 as a field recorder to record ProResHQ video,with GH4 video setting as AVCHD(FHD/17M50i),

but with HDMI Rec Ouput , should I choose 4:2:2 8 bit, or 4:2:2 10 bit,

I understand that when HDMI Rec Output set at 4:2;2 10 bit, I cannot film 4K internally at GH4.

But as long as when I shoot 4K, I need to go back to menu to reset the video file format from AVCHD (which is for Ninja to function) to MOV or MP4(LPCM), then why not choose a higher bit rate output format.

Any advices are really appreciated !!

Cheers

Edmond

Should I discard Ninja 2 and just focus on GH4 4K internal video recording ???

Please help me to figure it out.

Thank you !

Hi Edmond. That is odd.

1: For sure I would go with MOV not MP4.

2. The Ninja2 only supports up to i60. Not p60. Perhaps everything other than AVCHD sends out a p60 signal?

3. Correct if setting to 10bit. Then you cannot record internally to the card.

What options are there on the HDMI output? (Are they the same as the GH3?)

Just checked the manual.

Can you try using MOV at 4k p25 ?

Hi Richard,

I have packed the camera as I am going tomorrow.

Will try it again at the resort.

Cheers

Keep us updated Edmond.

For sure it will be a simple setting that needs changing - enjoy the trip!

After grading my GH4 footage with DaVinci Resolve Lite, I have edited a short film with 1920 x 1080 resolution and posted at youtube.

My experience with GH-4 is enjoy it very much. I use two lens during my trip, 7-14 for wide, 60mm for macro.

In fact, I don't need much for post correcting the 4K video. But if I want to do some correcting with the MOV file, I find it is not as extensive than what I did with BMPCC ProRes file.

I am sure I will buy the Shogun later in order to record 4K ProRes at lease. Not sure if Shogun can record 4K DNG file ??

Cheers

Nice one Edmond, I should have mine setup this weekend!

I also have the 7-14 & the 12-50 but will also add the 60mm at some point.

Took my GH4 with the 60mm out this past Sunday. No video. Just stills. Well happy with it.

This coming weekend I'll have the 7-14mm in the water with the 170mm dome and Keldans :-)

Trickster, I'm interested in seeing your results with the 7-14 & 170mm dome.

I will have my 7-14 soon & 6inch dome but am also considering the 170mm.

Can you compare the Zen 170mm glassdome with Nauticam 6" dome ?? Thank you !!

And I'm very interested in your findings with the 12-50 Pete

Great stuff from both Edmond and thetrickster. I have the GH4 in hand, but I'm waiting on my housing. Heading out to the Oil Rigs this weekend, so will probably using my GH2 again unless my shop gets a delivery in the next couple of days.

Edmond, what picture profile are you using? I'm leaning towards CineLike V and shooting UHD at 30p.

No worries nick, the lens & port are sitting here in front of me waiting for my camera to arrive hopefully tomorrow

Pencilled in Saturday arvo for it's maiden voyage with the 12-50 so stay tuned

The 170mm is bigger than i thought!!

Hopefully getting in the water this coming Sunday or Monday.

Can anyone tell me if they have actually got the GH4 to work with a Ninja2 yet? I had it working with the Small HD DP4 but no luck so far with the Ninja2.

Thanks,

Todd

It Works!! But only in NTSC 23.94 and Cinema 24 FPS only

Thank you! Are you shooting MOV files?

Yep MOV, 4K 100Mbps in NTSC 23.94

Thanks again!
