Edit decision list

An edit decision list or EDL is used in the post-production process of film editing and video editing. The list contains an ordered list of reel and timecode data representing where each video clip can be obtained in order to conform the final cut.

EDLs are created by offline editing systems, or can be paper documents constructed by hand such as shot logging. These days, linear video editing systems have been superseded by non linear editing (NLE) systems which can output EDLs electronically to allow autoconform on an online editing system – the recreation of an edited programme from the original sources (usually video tapes) and the editing decisions in the EDL.

They are also often used in the digital video editing world, so rather than referring to reels they can refer to sequences of images stored on disk.

Some formats, such as CMX3600, can represent simple editing decisions only. XML, the Advanced Authoring Format (AAF), and AviSynth scripts are relatively advanced file formats that can contain sophisticated EDLs.

Decision list

Decision lists are a representation for Boolean functions. Single term decision lists are more expressive than disjunctions and conjunctions; however, 1-term decision lists are less expressive than the general disjunctive normal form and the conjunctive normal form.

The language specified by a k-length decision list includes as a subset the language specified by a k-depth decision tree.

Learning decision lists can be used for attribute efficient learning.

Definition

A decision list (DL) of length is of the form:

where is the th formula and is the th boolean for . The last if-then-else is the default case, which means formula is always equal to true. A -DL is a decision list where all of formulas have at most terms. Sometimes "decision list" is used to refer to a 1-DL, where all of the formulas are either a variable or its negation.

YOOX Net-a-Porter Group

YOOX NET-A-PORTER GROUP S.p.A is an Italian internet mail order retailer of men's and women's multibrand clothing and accessories founded on 5 October 2015 after the merger between YOOX GROUP, the global Internet retailing partner for leading fashion and luxury brands, and THE NET-A-PORTER GROUP, the world’s premier online luxury fashion destination for content and commerce. Yoox was founded by Federico Marchetti, a former investment banker, in Zola Predosa near Bologna in 2000 and has become an e-commerce company that serves "more than 100 countries worldwide". Compagnie Financière Richemont agreed to merge Net-a-Porter with Yoox without the knowledge of Net-a-Porter founder Natalie Massenet for a valuation of about £950 million (about $1.4 billion), which was much lower than what Morgan Stanley bankers believed the business to be worth.

YOOX history

YOOX’s concept is to buy up overstocked or unsold items from previous seasons in "a direct relationship" from renowned fashion houses "including Dolce & Gabbana, Diesel, Gucci, Armani and Cavalli" as well as "manufacturers and authorized dealers" and sell them online at discounted outlet prices. This is to enable "luxury brands to off-load last year's merchandise without undermining their brands or cannibalizing sales at their existing stores". Vintage designer clothing (Chanel, Dior, Pucci etc.) is collected with the help of fashion editor Polly Allen Mellen and sold at special occasions. Some fashion designers have created capsule collections exclusively for yoox.com, such as Hussein Chalayan (menswear) or Alexandre Herchcovitch.

Da Vinci Systems

Da Vinci Systems LLC. designed, manufactured and marketed high-end post production color grading and film restoration systems for feature films, video production and broadcast post production facilities. It was based in Coral Springs, Florida with offices in Los Angeles, New York, London and Singapore. While previously wholly owned by JDS Uniphase Corporation (NASDAQ: JDSU), the assets of da Vinci Systems were acquired by Blackmagic Design, a privately owned company, in September 2009.

As one of the earliest pioneers in post production products, da Vinci Systems introduced several innovative products and was considered a significant player in the post production industry during its 25 years of operation. da Vinci Systems equipment was initially developed by Video Tape Associates (VTA) in 1982 for use by the Hollywood, Florida, USA-based production/post production facility to alter and enhance colors from scanned film and video tape. The Wiz system, as it was later known, was marketed to other post production facilities, laying the foundation for the creation of the colorist and the post production color suite.

Premiere was one of the first computer-based NLEs (non-linear editing system), with its first release on Mac in 1991. Up until version Premiere Pro 2.0 (CS2), the software packaging featured a galloping horse, in a nod to Eadweard Muybridge's work, "Sallie Gardner at a Gallop".
