Video

A video codec is a device or software that enables video compression and/or decompression for digital video. The compression usually employs lossy data compression. Historically, video was stored as an analog signal on magnetic tape. Around the time when the compact disc entered the market as a digital-format replacement for analog audio, it became feasible to also begin storing and using video in digital form, and a variety of such technologies began to emerge. Audio and video call for customized methods of compression. Engineers and mathematicians have tried a number of solutions for tackling this problem.

There is a complex balance between the video quality, the quantity of the data needed to represent it (also known as the bit rate), the complexity of the encoding and decoding algorithms, robustness to data losses and errors, ease of editing, random access, the state of the art of compression algorithm design, end-to-end delay, and a number of other factors.

Theatre auditions

Theatre auditions are when actors tryout for a role in a staged production. Theatre is that branch of the performing arts concerned with acting out stories in front of an audience using combinations of speech, gesture, music, dance, sound and spectacle. When actors audition for a theatre production, often they will perform monologues from plays other than the play they're auditioning for. Occasionally, the director of the production will ask an actor to prepare material from the show the will be performing in. To get more information on theatre auditions, go to Theatre Auditions.

TV show auditions

TV show auditions are when actors audition for a part on a television show; some types of television show are: dramas, sit-coms (situation comedy) and soap operas. TV auditions are very similar to Film and Theatre auditions. The main difference is time. Television is always under a time constraint. A script is written in a week, and that next week it must be cast, in order to film the week after that. Most television auditions are for guest starring spots, under fives and extras. Since there are a limited amount of recurring roles on television shows, episodic character casting is what most TV auditions are for.

Aspect Ratio

Aspect ratio describes the dimensions of video screens and video picture elements. All popular video formats are rectilinear, and so can be described by a ratio between width and height. The screen aspect ratio of a traditional television screen is 4:3, or about 1.33:1. High definition televisions use an aspect ratio of 16:9, or about 1.78:1. The aspect ratio of a full 35 mm film frame with soundtrack.

Ratios where the height is taller than the width are uncommon in general everyday use, but do have application in computer systems where the screen may be better suited for a vertical layout. The most common tall aspect ratio of 3:4 is referred to as portrait mode and is created by physically rotating the display device 90 degrees from the normal position. Other tall aspect ratios such as 9:16 are technically possible but rarely used. Pixels on computer monitors are usually square, but pixels used in digital video often have non-square aspect ratios, such as those used in the PAL and NTSC variants of the CCIR 601 digital video standard, and the corresponding anamorphic widescreen formats.

Producer

The primary role of a television producer is to control all aspects of production, ranging from show idea development and cast hiring to shoot supervision and fact checking. Often the producer is responsible for the show's overall quality and survivability, though the roles depend on the particular show or organization. Some producers take more of an executive role, in that they conceive new programs and pitch them to the networks, but upon acceptance, they focus on business matters, such as budgets and contracts. Other producers are more involved with the day-to-day workings, participating in activities such as screenwriting, set design, casting, and even directing. In television, there are varieties of different producers on a show. A traditional producer is one who manages a show's budget and maintains a schedule, but this is no longer the case in modern television. In fact, nowadays a producer is almost synonymous with a writer. In production, the video/film is created and shot. More crew will be recruited at this stage, such as the property master, script supervisor, assistant directors, stills photographer, picture editor, and sound editors. These are just the most common roles in filmmaking; the production office will be free to create any unique blend of roles to suit the various responsibilities possible during the production of a film. A typical day's shooting begins with the crew arriving on the set/location by their call time. Actors usually have their own separate call times. Since set construction, dressing and lighting can take many hours or even days, they are often set up in advance. The grip, electric and production design crews are typically a step ahead of the camera and sound departments: for efficiency's sake, while a scene is being filmed, they are already preparing the next one. While the crew prepares their equipment, the actors are wardrobed in their costumes and attend the hair and make-up departments. The actors rehearse the script and blocking with the director and the camera and sound crews rehearse with them and make final tweaks. Finally, shot the action in as many takes as the director wishes.

Law Firm

A law firm is a business entity formed by one or more lawyers to engage in the practice of law. The primary service rendered by a law firm is to advise client’s individuals or corporations about their legal rights and responsibilities, and to represent clients in civil or criminal cases, business transactions, and other matters in which legal advice and other assistance are sought.

In many countries, including the United States and the United Kingdom, there is a rule that only lawyers may have an ownership interest in, or be managers of, a law firm. Thus, law firms cannot quickly raise capital through initial public offerings on the stock market, like most corporations. In the United States this rule is promulgated by the American Bar Association and is adhered to in all U.S. jurisdictions, except the District of Columbia. The U.K. has a similar rule, but in recent years law firms have been able to take on a limited number of non-lawyer partners.

The rule was created in order to prevent conflicts of interest. In the adversarial system of justice, a lawyer has a duty to be a zealous and loyal advocate on behalf of the client, and also has a duty to not bill the client unreasonably. Also, as an officer of the court, a lawyer has a duty to be honest and to not file frivolous cases or raise frivolous defenses. A lawyer working as a shareholder-employee of a publicly traded law firm would be strongly tempted to evaluate decisions in terms of their effect on the stock price and the shareholders, which would directly conflict with the lawyer's duties to the client and to the courts.

Law firms are typically organized around partners, who are joint owners and business directors of the legal operation; associates, who are employees of the firm with the prospect of becoming partners; and a variety of staff employees, providing paralegal, clerical, and other support services. An associate may have to wait as long as 9 years before the decision is made as to whether the associate "makes partner." Many law firms have an "up or out policy" pioneered around 1900 by partner Paul Cravath of Cravath, Swaine & Moore: associates who do not make partner are required to resign and join another firm, go it alone as a solo practitioner, go to work in-house in a corporate legal department, or change professions burnout rates are very high in law.

Making partner is very prestigious at large or midsized firms, due to the competition that naturally results from higher associate-to-partner ratios. Such firms may take out advertisements in legal newspapers to announce who has made partner. Traditionally, partners shared directly in the profits of the firm, after paying salaried employees, the landlord, and the usual costs of furniture, office supplies, and books for the law library or a database subscription. Partners in a limited liability partnership can largely operate autonomously with regard to cultivating new business and servicing existing clients within their book of business. However, many large law firms have moved to a two-tiered partnership model, with equity and non-equity partners. Equity partners are considered to have ownership stakes in the firm, and share in the profits and losses of the firm. Non-equity partners are generally paid a fixed salary albeit much higher than associates, and they are often granted certain limited voting rights with respect to firm operations. The oldest continuing partnership in the United States is that of Cadwalader, Wickersham & Taft, founded in 1792 in New York City.
