Industry Standard Connection Terminals (XH G1 only)

While there are many situations that call for smaller,

lighter HD cameras, most such products are unsuit-

able for professional applications because they

lack the necessary interface capability. The Canon

XH G1 features HD-SDI (SMPTE 299M) or SD-SDI

(SMPTE 272M) output, Genlock input, and SMPTE

Time Code in/out connectors.

HD-SDI—The HD-SDI output provides a 1,485Gbps

60i signal at 1920 x 1080 resolution and with

4:2:2 color sampling with embedded audio and

time code. Because a single industry standard connection carries

video, audio, SMPTE (LTC) Time Code, and digital audio, cabling

complexity is significantly reduced. It enables longer cable runs,

improves operator mobility, and simplifies cabling.

Genlock—The Genlock input enables multi-camera synchroniza-

tion in live-switched environments. It can accept either an SD

(black burst) or HD (tri-level) sync signal when shooting HD.

SMPTE Time Code—A switchable SMPTE input/output port accom-

modates time code requirements during multi-camera shoots and

post-production.

Shutter Speeds

When shooting with the shutter priority auto exposure mode, the

XH G1 and XH A1 provide 14 different shutter speeds ranging from

1/3 to 1/15,000 of a second. The 24F mode includes a 1/48 second

setting that perfectly matches the shutter speed of a motion picture

film camera. (For NTSC 60i/30F and PAL 50i/25F, there are 13 avail-

able settings.)

Superior Connectivity

The XH G1 and XH A1 include a full complement of input and output

ports to meet just about any interface requirement. Two XLR mic/line

audio inputs accommodate professional balanced connections.

Also provided are industry standard connectors, including component

(HD/SD) and composite video outputs (BNC/RCA), an IEEE 1394

(Firewire) port, a LANC terminal, and a headphone jack.

Audio Recording Control

Individual audio level controls, switchable 20 dB mic attenuation,

12 dB mic gain boost, and various monitoring options provide full

control over the sound as it is recorded. They even include switch-

able phantom power (+48V) to eliminate the need for any external

power supply with direct mic input. An external microphone holder

is provided for on-camera mounting and for an optionalprofessional

shotgun microphone.

Production Environments.
