Kinefinity MAVO LF - In Depth (2 / 3)

The MAVO LF is Kinefinity's current flagship.

SDI and HDMI

The two SDI and HDMI outputs of the MAVO LF with the KineBack-W are robust and worked without any problems. 

The greatest caveat is that there isn't any way to send a clean output via SDI without turning off all overlays for the EVF and KineMon monitor.

The MAVO's on-screen menus are always enabled on all outputs or always disabled on all outputs, depending on what you select. Although the MAVO LF has two SDI outputs and two outputs for a Kinefinity EVF and/or KineMon monitor, you cannot use the MAVO LF to specify what is sent from these outputs. For example, you cannot send a clean feed through one SDI and a LUT through the other. And you cannot keep overlays on your EVF and send a clean feed to your monitor. This lack of customization does not make the camera exactly friendly for larger productions.

However, this is only true for current hardware. These important features are to be added in the next product generation.

Another problem is that there isn't any audio being routed through the SDI outputs in Live View. Maybe this has to do with the fact that you can only select 59.94 or 60 frames per second as video output. According to Kinefinity, this is only possible when the camera is in playback mode. The situation is even more difficult for the HDMI outputs. Audio output here is neither possible in Live View nor in playback mode.


KineMON-7H Monitor

Kinefinity has a new 7-inch field monitor, the KineMON-7H.


It is a 1080p Full-HD High-Bright monitor 7´ with a claimed brightness of 1000nit. The monitor requires only one Kine video cord to get power supply and a video signal from the MAVO LF.

The screen has 325ppi, a contrast ratio of 1000:1, a good full viewing angle and LED backlight.

You can also add a 7-inch KineMON sunhood to facilitate shooting in ultra-bright conditions.

The KineMON-7H has a standard 1/4´ threaded hole and two pin holes at the bottom to attach itself to the camera.



Since the monitor receives its power and video signal through a single cord, the monitor always displays what you have on the camera. There are not many things you can do on the monitor itself. These include waveform, brightness and contrast. 

It would be nice if the monitor had more video assist features built in, such as audiometer, image zoom, false colours, etc.


KineEVF

Kinefinity has its own EVF (ElectronicViewFinder) called KineEVF.

The viewfinder is equipped with a Micro-OLED 1080p display that provides a precise and sharp image with 16 million colours.

The EVF is connected by a single KineMon MOCO cord to provide both power supply and the video signal. This makes it a proprietary EVF designed specifically for Kinefinity cameras. The MAVO LF has two video outputs for MOCO cords, so you can connect both the KineEVF and KineMON-7H at the same time.

It weighs only 290g.



The only drawback of the EVF is that there are just a few options to make adjustments: an ON/OFF switch, a scroll wheel and two buttons on the side. 

You can change the brightness from standard to high and you can activate the peak values and a histogram. Since the EVF receives its power and video signal through the MOCO cord, any menu you call up or change, such as the sharpness input, will be displayed live in the EVF.

As far as mounting is concerned, there are no 1/4´ or 3/8´ mounting points. It is specially designed for working with the Movcam EVF bracket.

The KineEVF is available in stores and can also be used together with the bracket for Built-in Wireless

The MAVO LF is capable of inserting a wireless card with Movcams DarkTower platform into the new KineBACK-W. This gives the MAVO LF wireless camera functionality, including wireless video transmission and wireless lens control system with Movcams lens motors. The wireless video can bridge up to 600m/900m depending on the DarkTower card used.


SSD recording media

The MAVO LF uses standard 2.5´ 7mm SSD SATA 3.0 recording media. There are many off-the-shelf 7mm SSD drives available, but the performance of third-party SSD drives is not guaranteed by Kinefinity. Kinefinity does not provide technical support or assistance with recording problems such as frame drop or data loss on third-party SSDs. Kinefinity manufactures its own 7mm KineMAG+ SSDs, which are available in 500GB and 1TB versions.



Unfortunately, the SSD must first be "ejected" via the menu before it can be removed - similar to what was the case for external media on PCs. 

The 6K file sizes will be enormous for both ProRes and cDNG. Recording 6K 24p in ProRes 422HQ is equivalent to 764GB for every hour of footage. You get at least 40 minutes of recording time with a 500GB KineMag.


Custom in-camera LUTs

With the MAVO you can upload a LUT to the camera. The LUT is not burned into the footage, it is always recorded in a log image (KineLOG3). The LUT you use at the time of recording is stored in the same folder.

There is currently only one LUT in the camera, the KC_NEUTM.cube.


Metadata

Apart from all the information recorded with your clips such as the LUT you used, Kinefinity also gives you the option of filling out a complete panel with all your recording details and information. This can be done via the menu, but the process is very small and somewhat time-consuming.

The MAVO & MAVO LF have built-in Wi-Fi, but there isn't yet any iOS or Android app to control the camera or make settings remotely.

Basically, there is a .txt file containing all information about your clip and camera settings, the .cube LUT file you used and a .bmp file that contains your shot with the LUT you used.


KineMOUNT

The MAVO LF uses the KineMOUNT, which has an active electronic connector. Thus, it supports the PL mounting adapter with /i tech. This mount is one of the most versatile systems on the market. It allows you to use a wide range of adapters including Sony E-Mount, PL-Mount, PL e-ND EF, EF e-ND and EF Enhancer. Kinefinity is one of the few cameras on the market with a Sony E-Mount option.


SideGrip

The SideGrip offers the same menu controls and functions that are available on the operator side of the camera. This is also where the BP-U style battery is used to power the camera. The SideGrip does not rotate or move.

The SideGrip controls are nicely placed, but it's not very ergonomically designed and not nearly as comfortable to hold as the hand-moulded controls from Sony, Canon and Panasonic. Also, it's attached directly to the body and doesn't use a rosette or cable, which means you can't move the handle when using the camera on a shoulder rig.


KineBack-W



The KineBack-W is really an optional accessory you need so as to make the MAVO a working camera. Without the KineBack-W, you can't record real professional audio, and you don't have any SDI outputs or timecode in/out.

The KineBack-W features dual 3G SDI monitoring outputs, dual XLR ports for phantom-powered 48V microphones, time code input and output, SYNC, DC outputs and an all-metal battery plate with V-mount connector and dual D-tap ports.


Audio

The KineBack-W has a recording module that supports two balanced MIC-INs with or without +48 V phantom power. The XLR ports face straight up, just like the URSA Mini (Pro) from Blackmagic Design.

As far as audio recording is concerned, there are a few things you need to be aware of. There is an audio section you can go to in the main menu. This is where you can choose to switch on the two XLR ports or just CH1 or CH2. This audio menu can also be accessed by double pressing the audio icon on the side of the camera. You can choose to activate phantom power, but there seems to be no way of assigning phantom power to only one of the two channels. There is no function for line level, only for microphone level.

You can also set the individual levels for the two XLR ports in the menu. The problem is that settings not made via the main menu will always adjust both channels at the same time. So, if you have both XLR inputs enabled and are using two microphones, any adjustment you make will be made for both microphones.

As for headphone monitoring, you can adjust the headphone volume in the Audio menu. You cannot choose whether to monitor only Channel 1 or only Channel 2 unless you have just one of the XLR ports activated.

One of the other big disadvantages with audio is that you can't set any of the channels to Auto. Unfortunately, there isn't any built-in limiter, either.

The biggest problem with audio at the moment is that it is not recorded in perfect sync when you use the XLR ports of the KineBack-W. The sound is not 100% in sync with the picture.
While the preamps sound pretty good and the audio quality is good, the audio recording and control options on the MAVO LF (with the KineBack-W) are rather limited.


V-Mount battery plate

The V-Mount battery plate has been designed to match the shape of the KineBack-W. The battery plate also has two D-Tap ports for powering other accessories. It is important to note that the D-Tap outputs are directly connected to the V-Mount battery, so the output voltage varies from 11V to 17V instead of the regulated 12V value.


Timecode Input and Output

The KineBACK-W also supports timecode input and output. This enables the output of timecode to other devices such as sound recording devices. The KineBack-W can also use timecode from an external timecode generator if you use the MAVO LF as a timecode slave.
The timecode port is a 5-pin MOCO socket, but can be converted to a BNC port or timecode port of other timecode generators if you use the corresponding Kine Timecode cords.
