IBC 2013: Atomos Samurai Blade update

• Panasonic 4K Camera/Recorder, VariCam 35, With New Super 35MM MOS Sensor, AVC-ULTRA Codecs For 4K

The VariCam 35 utilizes a new Panasonic super 35mm MOS sensor for 4096 x 2160 (17:9) 4K image capture; this imager when combined with the AVC-ULTRA codecs for 4K enables very manageable and practical 4K production file sizes. The new imager boasts an impressive 14+ stops of latitude, and faithfully captures high-contrast, wide dynamic range imagery without compromise. Powerful color management capabilities provide a much extended color gamut for impeccable image fidelity, and permit support for an Academy Color Encoding System (ACES) workflow for full fidelity mastering of original source material.

Among the camera/recorder’s top-level production features are real-time, high frame rate, variable speed 4K recording up to 120fps, proving the capability for master level 2K/FHD recording; and advanced workflows with parallel simultaneous 4K/ UHD, reference 2K/HD and proxy recordings for in-camera on-set color grading and monitoring / editing ease. The camera also features a newly-developed OLED electronic viewfinder (EVF) with optical zoom functionality. Lastly, 24-bit LPCM audio is added for in-camera audio master recording.

The VariCam 35 will deliver an unprecedented breadth of recording formats, including 4K and UHD in AVC-ULTRA 4K, and 2K and FHD in AVC-Intra 100/200.* Addressing the need for high-speed file exchange, the camera encodes high-resolution proxy files in parallel with 4K and 2K production formats, enabling fast, efficient offline editing, at bit rates from 6 Mbps down to 1.5Mbps. Wireless workflows for proxy streaming and metadata management will also be available.

The VariCam 35 will use Panasonic’s new expressP2 card for high frame rate and 4K recording (see separate news release). The camera is equipped with a total of four memory card slots, two for expressP2 cards and two for microP2 cards. The new expressP2 card can record up to 130 minutes of 4K/24p content. The microP2 card is designed for recording HD or 2K at more typical production frame rates.

Professional interfaces include: 3G-HD-SDI x4 for 4K QUAD output; 3G-HD-SDI x2 for RAW output; an HD-SDI out for monitoring (down-converting from 4K); and two XLR inputs to record four channels of 24-bit, 48KHz audio. A multi-connector facilitates docking the camera head to the recording module. In another striking design innovation, the VariCam 35 boasts a removable control panel to facilitate real-time control and easy access when the camera is in a fixed position. The VariCam 35 features a standard 35mm PL mount.

The VariCam 35 will launch fall 2014, with pricing to be announced.

• Surprise: There would be also a VariCam HS, a 2/3” VariCam that features high-speed 1080p image capture of up to 240fps.

Both new VariCam models (the VariCam 35 and VariCam HS) boast an inventive design innovation whereby the 4K and 2/3” camera heads are separate from but dockable to the AVC-ULTRA recording module, enabling professionals to switch between s35mm and 2/3” camera heads to best suit their creative needs.

Pure speculation, I'm wondering if that AVC-ULTRA recording module can also be used with Panasonic GH4 via its YAGH A/V-interface unit?
