Professional JackPack (XH G1 only)
While there are many situations that call for smaller,
lighter HD cameras, most such productsare unsuit-
able for professional applications because they
lack the necessary interface capability. The Canon
XH G1 featuresa Professional JackPackwith HD-SDI
(SMPTE 299M) or SD-SDI (SMPTE 272M) output,
Genlock input, and SMPTETime Code in/out con-
nectors. 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. The Genlock input enables multi-camera
synchronization in live-switched environments. It can accept either
an SD (blackburst) or HD (tri-level) sync signal when shooting HD.
A switchable SMPTE input/output port accommodates 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 ofa second. The 24F mode includesa 1/48 second
setting that perfectly matches the shutter speed ofa motion picture
film camera. (For NTSC 60i/30F and PAL50i/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 aboutany 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 micattenuation,
12 dB mic gain boost, and various monitoring optionsprovide 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 supplywith direct mic input. An external microphone holder
is provided for on-camera mounting and for an optional
professionalshotgun microphone.
