31. Selecting a
Camera Body
‣ Which video enabled DSLR you choose
is largely a matter of personal
preference
‣ We highly recommend you actually try
out or test a camera before deciding on
purchasing it
‣ You can't do much with the footage if
the camera doesn’t shoot the frame rate
or resolution that your project requires
32. Ergonomics
‣ How the camera feels in your hands is
an important part of choosing a video
enabled DSLR.
‣ Size – The body you choose should fit
your hands well.
‣ Weight – Pro bodies (or bodies that
have battery grips installed) tend to be
heavier which provides a nice counter
balance to longer lenses.
33. Sensor Resolution
‣ When it comes to sensor resolution and
video, don't let the megapixel count
influence your choice of a camera body.
‣ Choose a camera body that meets the
megapixel requirements of your still
images and don’t worry about sensor
resolution for video.
‣ The 21.1 megapixel Canon 5D MKII
that has a max resolution of 5616 x
3744 when taking still photos.
‣ When shooting video at 1920 x 1080,
your effective megapixel count is only
2.1 megapixels!
34. Full Frame Vs.
Cropped Sensors
‣ A full frame sensor is one that matches
the size of a 35mm film frame
and the sensor is approximately 36mm
x 24mm.
‣ Manufactures like Canon, Nikon and
Panasonic have different sizes for their
cropped sensors or smaller sensors but
generally adhere to standardized sizes
based on the APS (advanced photo
system).
‣ Cropped (or smaller) sensors multiply
the focal range of any given lens.
35. Full Frame Vs.
Cropped Sensors
‣ As a general rule of thumb, the larger
the sensor the greater the influence on
depth of field (DOF).
‣ Put simply, a larger sensor will allow
you to blur the background easier than
a smaller sensor with the same lens.
‣ A driving force in the popularity of video
DSLRs is that their sensors are
gigantic. Those large sensors allow for
a much greater control in the depth of
field (which many equate to a cinematic
look).

38. Crop Factors
‣ 1.3 – Crop factor used by Canon on
some of their 1-series bodies that use a
APS – H sensor like the 1D Mark
‣ 1.5 – Crop factor is employed by Nikon
for all of its non-full frame
‣ 1.6 – This crop factor is used by Canon
for their APS-C bodies like the 7D and
the Digital Rebel
‣ 2.0 – A large crop factor ratio that’s
used by Micro Four Thirds image
sensors like the one featured on the
Panasonic Lumix GH1 DSLR
39. Frame Rate Options
‣ 60 fps (59.94 fps)
Common frame rate for 720p HD
Can be used for overcranking
‣ 30 fps (really 29.97 fps)
The most common frame rate for
broadcast in the U.S. and other
‣ 25 fps
The common frame rate of video used in
Europe and around the world that use the
PAL standard.
‣ 24 fps (23.98 fps)
A rate that closely matches that of film
40. Frame Rate Options
‣ For footage that mimics film, a good
choice is to record 24 (23.98) fps
‣ For footage that is going to be used for
broadcast 30 (29.97) fps is a good
choice (1920 x 1080)
‣ If working with the Phase Alternating
Line (PAL) standard, you’ll use 25fps.
‣ For footage shot 1280 x 720, then 60
(59.94) fps is the best choice for
broadcast in NTSC based countries and
50 fps for PAL countries.

42. Recording Length
Limitations
‣ Most video enabled DSLRs format their
memory cards using the Windows FAT
32 file system.
‣ This system limits files to 4GB or about
12min of continuous recording.
‣ Other manufacturers impose even lower
limits due to hardware performance.
‣ This limit sounds like it might be
crippling but in most cases you can
work around it.
43. Recording Length
Limitations
‣ Plan Breaks– If recording an interview
estimate how many questions you can
get in 12minutes. If you’re recording a
concert, stop after each song.
‣ Minimize down time – Have a second
card ready to go. We keep a second
card in the strap to speed things up.
‣ Stagger Coverage – If using multiple
cameras, don't start or stop them all at
the same time. You can get overlapping
coverage between two or more
cameras.
64. Making a Plan
‣ Storyboard
‣ Sketch
‣ Camera
‣ Shot list
‣ Lighting diagrams
65. Photoshop for
art Direction
‣ Shoot test shots in a raw format
‣ Organize with Adobe Bridge or
Lightroom
‣ Open in Camera Raw
‣ Color grade to desired look
‣ Share with crew for lighting direction
71. Impact of Light and
Motion on Focus
‣ If you’re shooting a lot of motion,
pay close attention to both the amount
of light as well as the quality of light
‣ The less light that’s available, the larger
an aperture you’ll have to use in order
to record a properly exposed image.
‣ This means that your depth of field will
decrease and it will be much harder to
keep your subject in focus.
‣ If you or your subject are moving, it
get’s even more tricky

Shutter Speed Aperture
73. The Window
‣ Imagine your camera is a window with
shutters that open and close.
‣ Aperture is the size of the window. If it’s
bigger more light gets through.
‣ Shutter Speed is the amount of time
that the shutters are open. The longer
they’re open, the more that comes in.
‣ Inside the room and are wearing
sunglasses. Your eyes become
desensitized to the light that comes in
(like a low ISO).
109. Why record
dual sound?
‣ Internal microphone quality
‣ Automatic Gain Control
‣ Difficulty in monitoring
‣ Challenge to keep constant levels

116. The WORKFLOW
‣ Transfer to Field Drive and Mirror
‣ Determine Editing Format
‣ Identify Storage Requirements
‣ Transfer to an Edit Drive
‣ Determine Transcoding Specs
‣ Organize Media
‣ Transcode Media (optional)
‣ Edit
118. LAPTOPS IN THE FIELD
‣ Laptops serve as “loading stations”
‣ Consider using multiple stations
‣ Stations don’t need to be the latest and
greatest hardware
‣ Stations should have:
‣ Ability to connect to card readers
‣ Portable drives
‣ Archiving devices like Blu-Ray burners
119. transferring from
Field Storage
‣ Never edit directly off of field storage
‣ Transfer all field assets to redundant
media drives
‣ Keep all field storage drives secure until
project completion and archive
‣ Field storage drives are like “tapes”
on a shelf
120.
121. Card Readers
‣ FireWire Readers
‣ Lexar or Hoodman
‣ ExpressCard
‣ Laptop with an ExpressCard slot
‣ Frees up ports for drives
‣ Multiple Card Reader
‣ Slower
‣ Ability to walk away
122. PLAN FOR STORAGE
‣ Storage space is consumed relatively
fast.
‣ Canon 5D Mark II
‣ 1920 X 1080 at 30 fps needs
approximately 320 MB of card space
for each minute of footage
‣ A 32 GB CF card will hold about 100
minutes of footage
‣ Often use bus-powered drives for field
124. Common Media
Folder Approach
‣ 01_Original Footage
‣ Card images or cloned copies
‣ 02_Selects
‣ Footage picks
‣ Adapt as needed
125. Renaming Files
‣ Optional
‣ Can use descriptive names
‣ Adobe Bridge
‣ Includes batch rename option
‣ Can preserve original name in
metadata for future
126. Make Selects &
Transcode
‣ Transcode only selected footage
‣ Reduces transcode time
‣ Removes extraneous footage
‣ Reduces storage burden
128. Why Transcode?
‣ Once the footage has been transferred,
you'll may need to convert it to a format
that can be edited.
‣ Ideally, video you edit should be
optimized for the editing system you’ve
chosen to edit with.
‣ Convert the files into a standard video
codec that supports real-time editing.
129. Why Transcode?
‣ While H.264 files are small, they do not
often make good source files.
‣ Have heavy compression that drains
your computer's processors to decode.
‣ Must choose codec that is a healthy
balance for quality and size.
130. Why Transcode?
‣ Not great in Final Cut Pro
‣ Motion JPEG OK
‣ H.264 terrible
‣ Doable if you don’t mind rendering and
spinning beach balls of death
‣ Does work in latest
Avid, Premiere Pro, and Sony Vegas
133. 64
Going 64-Bit
‣ Make sure you are using 64-bit OS
‣ Windows 7 or
OSX Snow Leopard Recommended
‣ Make sure to update plug-ins and
drivers to be 64-bit
Bit
‣ Add more RAM to take advantage of
64-bit benefits fully
‣ 2GB per core is a “good start”
‣ Go for fast RAM
134. Premiere PRO CS5
‣ 64-bit Performance
‣ GPU-accelerated Mercury Playback
Engine for faster responsiveness
‣ Make sure you upgrade or have
proper video card.
‣ Make sure you download drivers
‣ Work with DSLR video natively
136. Color Grading
‣ Advanced manipulation of color
for storytelling purposes
‣ Black & White
‣ Special Effects
‣ Glows
‣ Grain & Stock Simulations
‣ Two powerful choices
