The Convergent Design Gemini 4:4:4 Uncompressed Video Recorder is a 10-bit video recorder that connects to a camera via HD-SDI, and records uncompressed 4:4:4 video as DPX files to up to two removable 1.8" Solid State Drives (SSDs). Weighing only a pound and recording the highest-quality HD formats to readily available removable media, the Gemini recorder is an ideal companion to compact cameras that feature 4:4:4 SDI output, such as the Sony PMW-F3.

That's not to say the Gemini isn't suitable for other large-sensor, small-form-factor cameras (such as the Sony XDCAM) that feature 8-bit, 4:2:2 HD-SDI output; if nothing else, the advantages of bypassing the camera's compression still apply here. And there are professional-level workflow options like recording footage to both SSDs (for instant backup) that serve well any serious digital cinema production.

But many of the features that set apart the Gemini are those that take advantage of 3G / dual-link SDI transmission. There's 4:4:4 recording of 2K at 24p as well as 1080p30 and 1080p24. There's 4:2:2 recording of high-frame-rate 1080p60/50, which enables true overcranked (slow-motion) capture.

Another key feature that makes Gemini 4:4:4 a true tool for digital cinematography is its support for Sony's S-Log gamma function, which is available for the PMW-F3 via a firmware upgrade. When applied to footage, the S-Log look-up table (LUT) provides additional stops of latitude for a wide dynamic range, setting up recorded DPX files beautifully for any digital intermediate (DI) post-production workflow. You can simultaneously record S-Log video to one SSD (for online editing) and the same footage with other burned-in LUTs to the second SSD (for easier & faster creation of offline proxies).

Transferring footage to an editing system is simple. The Gemini 4:4:4 comes with an SSD-to-eSATA transfer station, so you can easily drag files to your Mac or PC and start editing either uncompressed files or with any editing codec in most popular NLE applications (support for Final Cut Pro, Avid, Edius, and Vegas is planned).

Note! The necessary 1.8" 256 and 512 GB SSD drives are sold separately.
