Panasonic GH4, FZ1000, LX100 and Sony AX100 - 4K Video Samples and Settings

Sorry if another like this has been created.

Here I have a GH4 with 12-35mm lens sample.


The jolting vibration of the Hong Kong Tram was mostly absorbed by my hand with the rest the OIS. Still, very large horizontal agitations could not be mitigated.

How do you like working with the FZ1000 for your theatrical shoots compared to the AX100?

The FZ1000 provides exposure compensation of +/1 3 EV for 4K video. The AX100 does not. In fact, GH4 does not either.
EV control is crucial for spotlights and stage lights. Without it, most faces will be overexposed.
The color and resolution between the two is not that much.

AX100 is wider at 29mm (35mm eqv) while the FZ1000 is 37mm. The AX100 is suited for coverage for the stage and unattended on a tripod as there is no 29 minute limit.

Regarding zooming. AX100 is ok. Neither of its speeds are that smooth. FZ1000's zooming capability is pretty poor.

IS is better on the Panasonic over Sony.

Billy, I actually never saw any overexposure issues with your stage shots from the AX100. They always looked excellent.

I can't say I've found the zooming on the AX100 to be anything but smooth. I would like more variability of the zoom, but what's there is smooth.

Your FZ1000 shots here are quite nice.

hey Ken!

agreed with the AX100. It continues to be a workhorse. It does offer the built in ND filters. Of course, it is not a replacement for EV control. But in a totally dark scene with ridiculous strong lighting. ND1 can work. Other than that, I had to post process.

While FZ1000 offers EV control in 4K, GH4 does not. puzzling.
cheers

That is simply untrue. I use ev control all the time with the GH4, shooting 4K (shutter priority mode). Just press the ev button and the back dial controls the ev adjustment. No puzzle.

i just checked again. If the top dial is at "S" for shutter priority mode. I cannot shoot at 4K resolution for movies. Only 1080p

If I use to MovieM mode[ ]. (P22 in GH4 manual)
I can set both shutter and aperture, but cannot change EV settings doing 4K movies capture.

What am I doing wrong?

You do NOT shoot movies unless you set the top dial to MovieM mode if you want control in video. With that set (Movie mode), you now fix the shutter (shutter priority). This means aperture and ISO are auto. Can you do that? Once you are sure you are in fixed shutter, in movie mode, and auto aperture press the ev button on top. You should be able to change the ev with the back dial. There is no logical reason why the video resolution has anything to do with ev setting (but logic is irrelevant, I do that all the time). I am not talking about the special 24fps wider 4K, just regular UHD, of course.

ok. i know what the issue is. I have been shooting in MovieM mode and Manual. Setting both shutter and aperture. Under Manual, exposure compensation is not available. Under Shutter priority, it is as you say. All this in 4K UHD.

GH4 and FZ1000 using CineV
AX100 using Cinematone

FZ1000 does not match well with GH4, the noise is higher.
AX100 is near impossible to match with the two Panasonic.

Is that due to noise or colors? Which one would you pick for maximum image quality in low light?

varying issues.
the AX100 is cleaner in low light.

i am trying again this week at the same venue using CineD instead of CineV.
Maybe the color will be closer to the Sony.

Trying to setup at my lab before a gig never really works.

AX100 with FZ1000 and GH4 using CineV

Start this week using all 4K cameras in CineV and max db settings. White balance in 3000K
Set all Sony AX100 in spotlight mode and 3000K
This is as close in color profile between the brands.
Grain wise. the FZ1000 keeps up with the GH4 under ISO800, best under ISO400.
This is hard to do in the theater.

This teaser was in CineV, max db, ISO800 and 3000K
AX100 using spotlight, max gain6db and 3000K

GH4 and FZ1000 at Cabaret. Some Sony AX100

Finished all videos from a recent week long school cabaret, Smokey Joe's Cafe.
I used 4 video capable cameras. 2 in the back with me, one in the balcony and one at a side.
Parents were helping with the balcony and side angles.

This 1st clip is all GH4 and FZ1000, with the FZ1000 doing the overhead.
Both were set at ISO400 for this tough dim lit spotlight scene.
3000K WB with adjustment of -1.33 EV. 1/60 sec shutter priority. CineV with highlight shadows at -5/+5
The FZ1000 was cropped to about 66% of the original 4K 2160p footage to better frame in the action, leaving out the front rows.
You can see the FZ1000 had enough resolution for this.

https://www.youtube.com/v/6j6dMc5qQP...on=3&vq=hd1080


This clip marries a AX100, a FZ1000 and a GH4. In that order.

https://www.youtube.com/v/bdMKxIreeu...on=3&vq=hd1080

AX100 set at 3000K and cinematone, -1 EV, 1/60 for the beginning portion
FZ1000 for the overheads, also 3000K and CineV, -1.33, Highlights Shadows -5/+5, 1/60 Shutter priority
GH4 for the wide angles after overhead portion to the end. 3000K and CineV, -1.33, Highlights Shadows -5/+5, 1/60, F/2.8 using 12-35 2.8

Used Final Cut Pro X to manage angles and titles.
The entire project occupied over 3 TB of hard disk space. This is for a 70 minutes program using just 3 main cameras and 3 mikes.

LX100 Handheld 4K Wedding Footage. ISO1600

Got the LX100 a day before a family wedding.
Have no idea what they had planned. Boy, was I surprised.
LX100 used with no filters.
ISO1600
WB with bride's wedding gown.
1/60 throughout
mostly F/2.8
Highlights & Shadows -5/+5
Stabilization was active.
RAW footage, no post editing. Just cutting.
Original sound from LX100 internal audio, no post processing. I used -3 settings. Nothing was clipped. Good mike.
Attachments done with Final Cut Pro X

https://www.youtube.com/v/njXI8E8WTw...on=3&vq=hd1080

Compare this with recent tripod mounted Panasonic cameras production:

First test footage with Olympus 40-150 F/2.8 Pro Lens

A lot of excitement over the Olympus 40-150 F/2.8 Pro Lens. They are right to be.
This is on a GH4 at ISO1600
Bad lighting as I have only one LED Zylight 90 to use.
The other side was plagued by fluorescent tubes. Yike!

All footage as is from the GH4, which were set at CineV max H/S and used Portrait and 1/60 shutter priority.

I only just saw this Billy. Very nicely done and some really nice footage, especially considering you just got the camera.

I just stumbled on this thread and don't understand your statement that the AX-100 doesn't have EV control. I have it always set in the menu to work with the knob on the front of the camera. I usually have it set between -.2 to -.7, but it can be set more or less. My biggest problem with filming stage productions it getting the white balance correct, because they are always changing the lighting during the shows.

that was a big mistake. The AX100 has many forms of exposure compensation. You are correct.
