Marketing description

The AJ-CX4000GJ camera recorder responds to the emerging needs of the broadcasting industry, such as high-quality 4K recording and network distribution, while retaining the broadcast-standard B4 lens mount and shoulder-mount design. The large-size 11.14 M-pixel image sensor provides a high horizontal resolution for recording of 4K/HDR images.

Key selling points

• 2/3-type lens mount secures a deep depth of field
• 11.14 M-pixel oversampling obtains a high horizontal resolution
• 4K achieves high sensitivity in High Sens mode
• HDR shooting is supported with HLG (Hybrid Log Gamma)
• A color filter achieves color reproduction that approaches the 3-chip type
• SDR monitoring gamma - gamma curves for monitoring HLG images with the SDR viewfinder or other SDR monitor
• HDR/SDR parallel output - dual SDI can output both HDR and SDR simultaneously
• VF/LCD HDR/SDR selector - assignable to the user button for easy switching between HDR and SDR even during recording
• Eight-mode gamma - select from HD/SD/FILMLIKE 1/FILMLIKE 2/FILMLIKE 3/FILM-REC/VIDEO-REC/HLG gamma curves
• Two optical filters - ND and CC, have four positions each
• Chromatic aberration compensation - the small amount of circumjacent chromatic aberration is compensated
• Dynamic range stretcher - suppresses blocked shadows and blown highlights to achieve a visually wide dynamic range
• Quality FBC - high-precision flash band compensation
• Digital zoom - 2x/3x/4x digital zoom boost
• Focus assist - Expand, Peaking and Focus Square
• Shockless AWB - a smooth transition occurs when switching white balance
• It is also equipped with an auto tracking white function
• WFM/vectorscope - simplified display on LCD and VF
• High-brightness zebra display - the zebra pattern can be displayed in white-out areas of the viewfinder image
• Y-GET - measures brightness at center and displays numerical data
• Lens files - it stores settings for interchangeable lenses
• Setup files - it makes color setting easier for multiple cameras
• Mode check - displays a list of the camera settings on VF and LCD
• Rec check - this lets you run a quick playback check of the clip-end
• User buttons - functions can be freely allocated to the five user buttons

Product features

• Large sensor and optical magnifying system achieve high-quality 4K/HDR shooting
  The AJ-CX4000GJ has the Panasonic original optical magnifying system. AJ-CX4000GJ chooses the image sensor, which secures a pixel size of 4.3 microns to obtain a wide dynamic range and has Dual Native ISO technology to achieve low noise even in dim lighting. This system achieves the operability and high image quality of the 2/3-type lens and 4K/HDR shooting.
• 0.005 lx of minimum illumination, high-sensitivity DS gain
  High sensitivity is achieved with DS gain. Combined with master gain, this enables a maximum +76 dB, for ultrahigh sensitive recording at minimum subject illumination of 0.005 lx.
• High-definition touch panel LCD with an HD 720p display capability
  The standard 3.5-type color LCD with approximately 2.76 M pixels allows for high-definition color monitoring. In addition, the touch panel makes it easy to operate the menu.
• 2.4-type black-and-white organic EL display
  Offers high brightness and clearly shows the status information even in outdoor environment, such as the timecode and audio input level.
• HEVC codec for high-image-quality 4K recording at low bit rates
  The AJ-CX4000GJ is capable of recording in various formats at different compression rates. Using the high-efficiency codec, HEVC (H.265, LongGOP, 10-bit, 4:2:0, MOV), the AJ-CX4000GJ records high-quality 4K 10-bit images at a 100 Mbps bit rate.
• MOV/P2 MXF file formats supported
  The AJ-CX4000GJ records MOV files that are highly compatible and easy to use. This file format supports long file names with up to 20 characters, allowing recorded video clips to be easily managed. And it supports the MXF P2 file format for broadcasting, enabling AVC-Intra or AVC-LongG HD recording.
• Equipped with expressP2 and microP2 card slots
  The AJ-CX4000GJ is provided with an expressP2 card slot to accept high-reliability broadcast-application storage media. This enables recording of large data as well as high-speed offloading. In addition, there are two microP2/SDXC memory card slots to achieve low running costs.
• A host of recording functions
  Using two microP2 cards, unlimited relay recording is possible. Simultaneous recording enhances recording reliability. Pre-REC, internal REC and metadata recording functions are provided.
• High-quality 24-bit four-channel audio recording
  It supports 24-bit/48 kHz four-channel digital audio recording. The audio source for each channel can be selected for each channel, choosing from mic-in, line-in and wireless receiver.
• Direct live streaming
  HD streaming is possible while images are being acquired. RTSP, RTMP and RTMPS streaming methods are compatible. Facebook, YouTube, and other streaming services are supported. Multicast streaming is also supported.
• 12G-SDI OUT compatible with 4K 10-bit 4:2:2 output
  The standard 12G-SDI output terminal delivers high-image-quality UHD 60p (50p) 10-bit 4:2:2 output. XLR audio input (2 CH) terminals compatible with +48-V phantom power supply as well as HDMI OUT, TC IN/TC OUT, GENLOCK IN, USB 3.0 (device) and USB 2.0 (host, wireless module) terminals are provided.
