HDV:What You NEED to Know


|
So, it's a new time for camcorders; the
Sony HVR-V1U is truly revolutionary, being the first full 1080 24p
camcorder on the market, using progressive sensors, and offering a full
1920 x 1080 resolution at the imager. The imager is a bit unique; it
follows the Fuji diagonal pixel placement, but offers much more to the
technology than merely putting pixels in a diagonal placement. More to
come on this technology later on, but for the moment, realize that a
pixel can do more in a CMOS device, simply because the pixel has an
address that may be specifically communicated with, whereas a CCD cannot
provide this benefit.

CMOS by nature, tends to be a bit
noisier than CCD does, yet Sony has addressed this very well, in my
opinion. We shot this camcorder in the middle of the night, virtually no
light, using the timelapse feature of the camcorder. While there is
indeed noise, it's much more clean than I'd expected.
The quarter-inch sensors were an
initial concern when I first was told of the size, however this has
proven to be a false issue. Under identical light, this camcorder with
its 1/4 chips equal or outperform virtually every other HDV camcorder I
shot it with. Because of the unique DSP, diagonal pixels, interpolation,
and ClearVid technology, CMOS has demonstrated that it absolutely can
create great pictures, even in less than ideal lighting situations.
24 and 30p! True 24 and 30p in this
camcorder, with no split resolution, no upsampled pixels or other
electronic voodoo, it's a true progressive image with a 1920 x 1080
resolution at the imager. The physical imager is 960 x 1080, but by
reading the pixels diagonally and combining pixel information (not
upsampling/downsampling, but re-addressing pixels) the resolution on
ingest is 1920 x 1080. The camera processes 1920 x 1080 in the 4:2:2
color sample scheme before processing for tape storage at 4:2:0, 1440 x
1080
I very much appreciate the button
placement. Autofocus, temp focus, Iris wheel, and Expanded focus are all
within a thumb's reach at all times. Expanded Focus may even be assigned
to both right and left sides of the camcorder, depending on user prefs.
You'll love the infinite focus and zoom rings as well. The lens is a
62mm size, so you'll need to get your hands on a new set of filters and
wide angle adapters if you're using threaded filters; I prefer a
mattebox, which will be available when the camcorder begins shipping. On
the subject of the lens, wait'll you see the 30X zoom. The optics are
only 20X, but using technology and the additional information, you can
enable an Digital Expansion mode that adds another 10X to the image
without degrading the quality that you'll normally see with
electronically enhanced zoom.

What don't I like? I don't like the
power button. It flips up instead of down for Camcorder-On
functionality. If anything, you're likely to accidentally bump a switch
downwards rather than upwards.
I don't care for the lack of assignable buttons. I'm very comfortable
with my HVRZ1U having Shot Transitions and six assignable buttons. With
this camcorder, if I want shot transitions I only get three assignables,
because the Shot Transitions are assigned to buttons 1-3 if you want
them. If you choose not to use Shot Transitions, you still have six
assignable buttons.
There are loads of assignable features
that may be put on buttons ranging from exposure and white balance
adjustments to backlight and spotlight compensation. I wish the Super
Slo Record mode was available as a button assignment, but that's one
feature you'll definitely want to check out if high resolution, super
smooth slo-mo is important to you. Picture Profiles also have some
serious tweaks available; if you want to match a specific film look,
it's not very hard, as the camcorder uses a 3D color Look Up Table (LUT).

Audio is not forgotten in this package
either; but there is no built-in microphone. I am delighted to see this,
but depending on your workflow, you may or may not appreciate this
feature. The US version of the camcorder ships with a reasonably good
quality short shotgun which is better than any built in mic I've ever
come across. Dual XLR inputs with Phantom power, line/mic switching,
discreet or combined channel switching, and auto/manual gain are also
available. The camcorder additionally offers Automatic Gain Control as
well.
The V1U is slightly larger than the
Sony HVR A1U, and slightly smaller than the HVR-Z1U, so it fits
perfectly in the middle of the size scheme.
Aside from my short overview, you can
download footage below.
These clips are 24p, processed as 60i,
and output as 24p. In the process, some information was lost; no NLE
currently supports 3:2 pulldown in HD resolution for HDV, so there was
no option but to recompress these files and process as they are managed
in order to watermark them. However, I've just discovered that the
CineForm Connect and Aspect HD application will correctly identify and
remove the 3:2 pulldown from the file; expect to see a new upload
shortly.

framegrabs from the V1U at full resolution
Clip One Captured from
the V1U with CineForm, converted to 4:2:2 with pulldown removal for
cutting segment out and adding watermark, then rendered back to .m2t,
using 24p w/pulldown inserted, similar to how the camcorder would
present it. Shot at approx 1/200, f4.
Clip Two (SuperSloMo) Super
SloMotion Record is segmented into three lengths; 3 seconds, 6 seconds,
and 12 seconds. Each has a value of X4. Recording in this mode does
cause the camcorder to reduce resolution at record. This is a zipped
file, 108MB in size.
