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 G
1
features HD-SDI (SMPTE
299
M) or SD-SDI
(SMPTE
272
M) 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 G
1
and XH A
1
provide
14
different shutter speeds ranging from
1
/
3
to
1
/
15
,
000
of a second. The
24
F mode includes a
1
/
48
second
setting that perfectly matches the shutter speed of a motion picture
film camera. (For NTSC
60
i/
30
F and PAL
50
i/
25
F, there are
13
avail-
able settings.)
Superior Connectivity
The XH G
1
and XH A
1
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.
