STEP 1: Insert your media card
Load a P2 card. Be sure to set the Media switch to "P2."
STEP 2: Set your time base
In the Recording Setup menu, set the Rec Format (P2) menu
item to 720/24PN. This will set the time base for your main program’s
shooting speed. To set up for variable frame rates you’ve got to choose
high-def 720p; you can also choose to work in a 24p or 30p time base,
which is the rate at which the rest of your footage will be shot, and
the kind of timeline you’ll be editing in. For film-like footage, you’d
normally want to choose 720/24PN. Note: The "N" is important; you need
to choose 720/24PN, not 720/24p!
STEP 3: Get into Film Cam mode
In the Scene File menu under Operation
, choose Film Cam. The HVX200 operates
in two different modes: Video Cam or Film
. For variable frame-rate shooting, it’s required to be in
Film Cam.
STEP 4: Choose your shutter speed
Film cameras use a rotating disc shutter-a physical disc with a wedge
cut out of it-that rotates in front of the film plane. As the disc
rotates, the cut-out wedge passes by the film and lets light through,
exposing the film until the solid portion of the disc rotates past to
block the light. The size of that wedge is expressed in degrees (a full
circle having 360 degrees); a typical film shutter angle is 180
degrees. To get convincing film-style slow-motion, you’ll usually want
to choose 180 degrees as your shutter speed as well. Exit the menus and
press the Shutter button, then use the
Speed Sel +/-
buttons until you see "Shutter 180.0d" displayed. If you see some other
degree speed, such as "Shutter 220.0d," go back into the Scene
menu and change your shutter angle using the
Syncro Scan menu item.
STEP 5: Pick your frame rate
Select your frame rate in the Scene File menu. Using the up/down
buttons, scroll to your desired frame rate (12, 18, 20, 22, 24, 26, 30,
32, 36, 48, or 60 frames per second). Speeds lower than 24 (i.e., 12,
18, 20, or 22) will result in motion that’s faster than normal (i.e.,
"fast motion"); speeds higher than 24 (i.e., 26, 30, 32, 36, 48, or 60)
will result in slow-motion. The higher the number, the slower the
STEP 6: Adjust your exposure
The frame rate and the exposure are linked when using the "180.0d"
shutter option. When you change the frame rate, it also changes the
exposure time. In a film camera, as the film moves faster through the
camera, the rotating-disc shutter spins faster, too. The HVX200
simulates this behavior; at 48 frames per second the shutter speed is
twice as fast as it would be at 24 frames per second; at 60 fps it’s
2.5 times as fast. This means you’ll want to open up the iris by 1 to
1.5 f-stops in order to get the equivalent exposure.
STEP 7: Shoot your footage
The footage will look "real-time" in the viewfinder as you shoot, but will be recorded on the P2 card with a 24p time base.
STEP 8: Preview your footage
Press the Mode Switch button to swap from Camera mode to
MCR mode. The thumbnail for the clip you just shot will be highlighted.
Press "play" to see it play back in smooth, sharp, frame-accurate
film-style slow-motion!
STEP 9: Use your HD clip for a DV project
At this point, you’ve got a high-def clip that can be directly imported
into Apple Final Cut Pro, Canopus Edius Broadcast or Avid Xpress Pro HD
and will play back on the timeline in slow-motion. But what if you’re
working on a standard-def DV project and want to use this clip? This is
where things get really cool: the camera can actually downconvert this
clip to DV and record it onto tape for you. Here’s how: Switch to DV
DUB mode. Make sure there’s a tape in the camera, and the power’s off.
Switch the Media switch to Tape,
and power the camera back on, and press and hold the Mode
until PC/DUB lights up.
STEP 10: Execute the dub
Make sure in the Dubbing Setup menu that you’ve chosen 720/24PN in the Format Sel
menu. Then, from the thumbnail page, select the clip you want to dub,
and press and hold down the two REC buttons-the camera will
automatically dub the clip from the P2 card over to your tape. You now
have a true slow-motion clip that can be used in a regular DV project.
Never thought you’d see the day, did you?

about the AG-HVX200, that Panasonic plans to ship with the camera.
Barry Says Keep In Mind
One of the fascinating and unique features of the new Panasonic
AG-HVX200 is its ability to shoot with true variable frame rates. You
can select from nearly a dozen speeds between 12 and 60 frames per
second, giving you freedom to do things you could previously only do
with a film camera-or, of course, the $70,000 VariCam. The AG-HVX200
offers more shooting modes, and more creative options, than any
camcorder on the market-even more than the VariCam, since the HVX200
supports 1080 recording and standard-def recording, too. You can choose
from fast-motion, slightly off-motion, mild slow-motion, true
slow-motion and super slow-motion speeds. These variable-speed clips
can be directly imported and used in any of the HVX200-aware editing
applications, such as Apple Final Cut Pro, Canopus Edius Broadcast and
Avid Xpress Pro HD. I’ve packed a few tricks into this one expanded
tutorial, including how to configure the camera to shoot for a
slow-motion sequence, how to play it back right in the field and even
how to incorporate slow-motion segments in your standard-def DV
Remember: Shooting variable-frame-rate footage requires shooting
in high-def. Though you can record SD footage to tape with the HVX200,
you’ll need a P2 card in order to record high-def material with this
