What is a TC?

TC stands for Telecine.  It is a way to copy and distribute a film from its original negative source.  However, TC movies are mostly seen on the Warez scene in an attempt to illegal share films.  TC copies are generally harder to find, since they require an editor to have direct access to a film as opposed to recording the film as a cam (where a video camera is used in theater) or as a TS (where a video camera is hooked up to a movie theater's projector and audio source) version.  TC movies usually leak from studios where workers on the lower end of the totem pole release them for their own profit and amusement.

A Telecine film is recorded using post-production equipment at a film studio.  Generally, TC versions of films are used in the post-production process by film editors, directors and producers as they splice together various bits of a film for the final cut.  When a TC release is shared, it generally has a few errors from the copying process due to the speed in which the film is copied from its original form.  Since the person copying it does not want to get caught, they may have to rush through the process which may cause some audio and video sync issues with the final product.

Due to the recent increase in studio leaks, many movie companies are opting to increase measures to combat piracy.  This includes allowing a certain number of TC film version to be leaked by internal personnel to track who is sharing them, how they are being shared and other information on those who are downloading these copies.  From there, movie studios can seek charges against those uploading, downloading and sharing TC films via file sharing networks, torrent sites and other means.  Since TC films are usually leaked from movie studios themselves, avoiding them is the best way to avoid being tracked when downloading illegal files on the Internet.
