Chroma Sub-Sampling p.34-35
Chroma sampling allows for a reduction of digital data with a limited affect to visual integrity.
Kind of like compression for the color difference signals. Human vision is less sensitive to color than brightness. 4 : 2 : 2 - Y : Cr : Cb - for every four times luma is sampled, the color
difference signals are sampled only twice. In 4:2:2, Luma is sampled at 13.5Mhz, the color difference signals are
sampled at 6.75Mhz each.

Avid Native File Format
MXF – Material eXchange Format - .mxf Container file like QuickTime, that wraps media
embedded with a variety of codecs with additional metadata like timecode.
OP-Atom – Avid, P2 standardized in SMPTE 390M OP1a – XDCAM standardized SMPTE 378M
Principles of Color correction p.44
Restoration - First – Restore the original
look of the scene. – Maximize tonal range.
– Preserving reality.
Adaptation- Second – Overall consistency.
– Dramatic Effect.
– Departing from realty.
Color Correction Groups
Secondary - applies color correction to a specific region based on a vector (color) or geographic region (shape).
Primary – applies color corrections on every pixel in an image or every pixel within a specific luma range.
LUMA RANGE • HIGHLIGHTS • MIDTONES • SHADOWS
Restoration Workflow
Open up the tonal range to provide the greatest range of luminance.
– Adjust Setup and Gain using waveform monitor. Gama can be used to your preference.
Neutralize color casts or white balance issues to ensure that colors are correct. – Use Hue offsets or auto correct balance.
Optical Printing
Optical Printing –
– An ANALOG photochemical process of coping film negative onto new negative, for the purpose of creating a visual effect.
– Create fades, dissolves, blowups, and double exposures for composites.
Film Scanning Sizes
Scanning “Rez” Full frame 4k 4,096 x 3,112
2k 2,048 x 1,556
Aspect Ratio 1.316
Reel Balancing The act of apportioning the footage between multiple 2000'
reels so that so that no reel has too little or too much film. This helps to divide the film up into manageable portions for audio post, distribution and projection.
The LFOA or “Last Frame of Action” for each reel should be a HARD cut - no music - with only ambience and no dialogue near the cut. This way changeovers can be made without the audience noticing.
Often Reel One is short 600’ to accommodate trailers and other material added by distributors.
No reel to be longer than 2000' Try to avoid reels shorter than 400’ Each Reel becomes it’s own sequence in the NLE. All Lists, exports and deliverables are done by individual reel.

Lists
Assemble List or Negative Cut List – The E.D.L.
Optical List – Indicates the effects and how to create them.
Dupe List – Anything that needs to be copied or shown twice
Pull List – Locates film for needed for digital scanning or negative
cutting.
GOOD LUCK!
