Panasonic will be releasing four new models of 4k camcorders to try to meet video production, broadcasting and distribution needs: AG-CX20, AG-CX18, HC-X1600 and HC-X1200. Both the AG-CX20 and AG-CX18 come with a removable handle unit, while the HC-X1600 is compatible with a separately sold handle unit, as the company has claimed in a statement.

The 4K 60p 10-bit camcorders combine a compact and lightweight body with optical performance featuring a 25mm wide-angle and 24x optical zoom.

These models have attempted to include improvements based on feedback received from industry workers. The main features are:

•  High-resolution OLED viewfinder with 1,770K dots and larger eyecups.
• USB-C port, which can also power the camcorder.
• A new low bitrate mode for FHD MP4 recording will be added in the next firmware update. It will support 28 Mbps (50p/59.94p), 24 Mbps (23.98p), and 20 Mbps (25p/29.97p).
• Low speed zoom: approximately 2.8 times slower than the previous model, to expand the range of video expression.
• Shooting guideline display support: allows users to check composition and horizontality.
• Network functionality: Supports Wi-Fi 5 GHz and adds USB tethering functionality.
• Improved operability through linkage with an app: The app “HC-ROP” now supports the live view function.

The models AG-CX20 and AG-CX18 admit FHD live broadcast via Wi-Fi and Ethernet. From a system standpoint, both are equipped with 3G-SDI and they admit simultaneous output with HDMI. Finally, the AG-CX20 provides NDI HX2-compliant IP connectivity and, by updating the firmware, it will be compatible with the protocol SRT for streaming.

Optical performance

The integrated lens offers an optical 24x zoom that ranges from 25mm wide angle to 600mm tele. i.ZOOM achieves 32x at 4K mode, and 48x at FHD mode. The 4-Drive Lens System drives the four lens groups independently.

Two Manual Rings are provided, one for focusing and the other for zoom or iris operation. The Manual Rings are designed with different sizes so the appropriate ring can be controlled. ND Filters can be selected from 1/4, 1/16, 1/64, and Clear, while glass is used as a countermeasure against scorching from sunlight condensation.

Face detection AF/AE

Focusing speed, stability and tracking performance for both 4K and FHD is achieved through Face Detection AF/AE together with the focus lens drive. Face Detection AF/AE is designed to provide precise focusing and sufficient exposure for subjects. In addition, subject tracking with color recognition can be activated by just touching the LCD panel.

5-Axis Hybrid O.I.S.

In addition to OIS (Optical Image Stabilization), Electronic Image Stabilization operates to detect and correct handshake in 5 axes, including rotational blurring. The Ball O.I.S. System reduces friction on the drive section, to try to achieve delicate correction even for small-amplitude handshake.

Body equipped with 4K/60p

The heat-dispersing design with a thin fan enables both a compact and lightweight body and 4K 60p high-definition recording. By pulling in air from the rear panel of the camera and dispersing heat from the front panel, extended shooting is achieved.

Recording modes

The camcorders support a variety of bit rates and formats. This enabled 4:2:2 10-bit internal recording with maximum 29.97 p in UHD, and maximum 59.94p in FHD. When set for 10-bit recording, the camcorder delivers 4K 60p 4:2:2 10-bit HDMI output. HEVC recording (LongGOP/10-bit 4:2:0/MOV) is also supported for recording UHD 59.94p at a high bit rate of 200 Mbps.

As for file formats, in addition to MOV, MP4, and AVCHD, the AG-CX20 also supports the P2 MXF for the editing system for broadcast stations, and recording by the AVC-Intra/AVC-LongG codecs is supported.

In addition, low bit rate recording formats of 28 Mbps (50p/59.94p), 24 Mbps (23.98p), and 20 Mbps (25p/29.97p) are planned to be added to the FHD MP4 recording in the next firmware update.

Functions and desings

A bright video light is built into the handle. The brightness can be adjusted by the dimmer dial for shooting in dim lighting. For shooting in darker conditions, commercially available IR lights are supported for IR (Infrared) Shooting.

The high-resolution 3.5-inch monitor with approximately 2,760 K dots is designed to provide visibility even in bright sunlight. It has an electrostatic touch panel that enables operation when selecting menus, and the size of the eyecups has been increased to try to reach comfort when shooting for long periods of time.

The included large-capacity battery does not protrude when attached and enables extended shooting.

Double SD card slot

Two SD memory card slots are provided. With Unlimited Relay Recording, the recording media switches automatically and seamlessly from Slot 1 to Slot 2. Simultaneous Recording or Background Recording is also selectable to match the workflow and card necessity.

• Unlimited Relay Recording: Data is recorded continuously by automatically switching the recording SD card from Slot 1 to Slot 2.
• Simultaneous Recording: Identical data is recorded onto cards in both slots.
• Background Recording: One SD card can be set in Slot 2 to record continuously, and another SD card can be set in Slot 1 to record necessary scenes by turning REC on and off.
• Dual Codec Recording (AG-CX20/AG-CX18 only): Records images simultaneously in two different formats, such as Main (UHD/FHD) and Sub (FHD), etc.

Audio recording

48V Phantom Power Supply/MIC/LINE Selectable XLR Audio Input with Manual Volume is equipped for each of 2 channels. Also supported is a 24-bit linear PCM system (MOV/P2 MXF), 16-bit AAC (MP4), or Dolby Audio system (AVCHD) high-quality 2-channel audio recording. The optional handle unit (VW-HU1) is required for HC-X1600.

Network functions

Supports 5GHz Wi-Fi® (IEEE802.11ac) in addition to the 2.4 GHz band. USB tethering using a smartphone is now also possible in unstable network environments such as those with frequent radio interference. Live view is now available via the tablet/smartphone app “HC ROP”.

The AG-CX20/AG-CX18 support RTMP (Real-Time Messaging Protocol), allowing live streaming of concerts, sporting event broadcasts, news, etc. to Facebook, YouTube, and others. The AG-CX20 will support image transmission protocol SRT in the next firmware upgrade.

The AG-CX20/AG-CX18 are equipped with an ethernet, and a wired LAN connection is available by using a commercially available USB LAN conversion adapter.

In addition, the AG-CX20 features the NDI HX2 mode, which allows transmission and camera control over an IP connection.

The AG-CX20/AG-CX18 also supports simultaneous 3G-SDI and HDMI output, with up to FHD 60p 4:2:2 10-bit video output from SDI.

Optional accesory

A Handle Unit (VW-HU1) has been added as an optional accessory. It is detached and equipped with a 2-channel XLR Audio Input, audio control, and LED light. Operation of the zoom lever attached to the Handle Unit maintains a constant zoom speed, which can be set in 7 steps from the menu.
