The Panasonic AJ-HDC27HP Varicam is a revolutionary camera-recorder that brought variable frame rate acquisition to the DVCPRO HD product line, making it the first high-definition production camera capable of variable frame rate recording at the touch of a button. Integrated in a single unit are an HD color video camera featuring a 1-million pixel IT-CCD pickup device and an DVCPRO HD format VTR incorporating advanced compression technology. The camera supports the SMPTE-296M 1280x720 scanning standard, delivering true 720p native progressive scan imagery that set a new benchmark for electronic field production and electronic news gathering applications.

The camera's defining innovation is its variable frame rate function, enabling frame-drop under-cranking and high-speed over-cranking shooting techniques previously confined to film production. The frame rate can be set from 4 fps to 60 fps in precise increments, while the shutter speed can be adjusted from 0.8% of the frame rate (aperture angle of 3 degrees) to 97.2% (aperture angle of 350 degrees). This allows cinematographers to create dramatic slow-motion effects and time-lapse sequences directly in-camera without post-processing. The camera automatically stores frame rate information and active frame data in the user bits of the sub-code track area, enabling seamless integration with 24p production workflows.

Panasonic developed exclusive film tone gamma curves for the Varicam, offering three gamma options: two cine curves for film-style reproduction and a conventional video gamma curve. This delivers natural gradations and rich color reproduction comparable to film, with sensitivity reaching approximately ISO 640, enabling shooting with the same feel as ultra-fine-grain films. The camera features a 12-bit analog-to-digital converter, 54 dB signal-to-noise ratio, and sensitivity of F12 at 2000 lux in 24P mode. Built-in CC filters (Cross, 3200K, 4300K, 6300K) and ND filters (Clear, 1/4, 1/16, 1/64) provide comprehensive light control. The camera accepts 2/3-inch bayonet mount lenses and supports Ultra Prime lenses for 35mm film cameras as a standard feature. Despite its professional capabilities, the unit weighs just 4.7 kg for the main body and consumes only 36 watts of power, making it highly portable for field production.
