Shot Composition
Transitions & Movements

Standard film: 24 fps
Persistence of vision
NTSC
525 scan lines of dots (480 used)
4:3 aspect ratio
30 fps interlaced fields

3. Video Process …..cont…. HDTV / DTV 3D 4K / UHD 480 720 1080 scan lines
Interlaced or progressive scan
24, 30, or 60 frame rate
480p / 1080i

4. Principles of video color
Light hits CCD (1 or 3 CCDs) (or CMOS)
Beam splitter splits into the 3 primary colors (electrical signals)
Other end--CRT, LCD, LED, DLP
Transducer / encoding - decoding
3 attributes of video color
Hue, saturation, luminance
Chrominance : hue & saturation -->
4/26/2017

5. Color (cont.) HUE... Primary colors: RGB Complementary colors
Cyan, magenta, yellow
White: all colors; Black: absence

6. Color Saturation Hue & Saturation=chrominance Luminance = brightness
continued...
Saturation
Intensity or vividness of color
Hue & Saturation=chrominance
Luminance = brightness
Luma & chroma

7. Three ‘parts’ of the camera
The camera body
The lens
The mount
4/26/2017

8. Camera Lenses Focal length…how wide or narrow /‘long lens’
Fixed focal length / prime lens
More common in film
Zoom Lens
Distance from front to back glass
Optical zoom vs. digital ‘zoom’
More common in video
Focus: soft, sharp
Depth of field / rack focus / selective
Depth of field is affected by focal length, aperture, and the distance of objects from the camera.

9. Camera Lenses Manual vs. autofocus
Front focus to focus a zoom lens
Must ‘critical focus’ each time
Back focus : use macro flange at back of lens
F-stop aperture (iris opening) / diaphram
F-22, 16, 11, 8, 5.6, 4 (double/half)
Don’t use to compensate for bad lighting
f-stops / t-stops / zoom vs. prime lens
Manual vs. autofocus
Sharp focus, selective focus, follow focus, rack focus, soft focus, swimming focus
** Photography is ** ---> the art of capturing and controlling light. Video, film, still images

10. On the Camera Studio cameras vs. field CCU for settings Tally lights
Lighting & filters
White balance
AGC / gain / decibels (video level)
4/26/2017

11. Camera Mounts & movements
Tripod and pedestal
Friction head / Fluid Head
Crane vs. jib
Dolly / track
SteadiCam vs. Handheld
Image stabilization
Robotics, follow me, Segue, ‘copter, cable mount, etc. (see online reading)
Camera movements
Pan, tilt, truck, dolly, arc, zoom, boom, crane, steady-cam, tracking, DVE
4/26/2017

12. Cameras -- composing shots
Field of view -- rules of thirds
LS/WS, est. shot, MS, CU, 2-shot, ots or o/s, head room, nose room, look space, cut-off lines, lead room, eye line
Sequencing shots / sequence
Depth composition (framing, focus)
Angle : eye level /high / low / canted
Symmetrical shots
Point of view: objective, subjective, presentational
4/26/2017

13. Illusion of Movement Composing individual ‘shots’
Editing shots together
Persistence of vision
24 vs. 30 fps (transfers)
‘shutter speed’
Demonstrated in the online reading
4/26/2017

14. Transitions What is a shot? Fade / cut / Diss / Wipe / DVE
‘Changing shots’ in a one-shot
Multi cam shoots vs. film style
Real time to Filmic time
Invisible / seamless edits
Sequences
Master Shot / cover shot
Crane, tracking, feather, 360 shot, follow, swish pan, snap zoom
Jump cuts / pop cuts
4/26/2017

15. The Static Frame
Visual storytelling involves interplay of blocking, lighting, costumes, and setting -- as captured by the camera
Edge of the frame / off-screen space
4/26/2017

16. Technical vs. aesthetics
What kind of camera? What kind of lighting? What kind of lens?
Consumer vs. Prosumer vs. professional cameras
Film vs. video cameras
How the story is told?
‘Language’ of visual storytelling -- Hollywood style, home movies style, new media style, NPPA / news style ###
