Cinematik is specialized in DVD (mostly) and BD/HD-DVD (not much) non-mainstream movies: art-house, classic, experimental cinema and so on. Staff itself position the tracker in such manner:
Cinematik is the greatest tracker in this domain, it offers its users more DVDs than Karagarga or Cinemageddon. The tracker doesn't host any kinds of rips at all. All the films must have English audiotrack or subtitles. Exceptions can be made only for movies that have not be officially released in a version with English language or subs.
No "Hollywood" style blockbusters, mainstream or popular film that can easily be found on other trackers, unless said film has remarkable artistic value or merit.
Invites are not given automatically at reaching any specific upload or experience - they may be asked in the forum. Another way to become a part of Tik is a simple interview in their IRC channel:
#cinematik on irc.cinematik.net
During interview you'll be asked some questions concerning cinematography.
Although many torrents may be dead reseed requests work well - in this way even a year-old dead torrent can be resurrected.
Cinematik is one of my favorite trackers. You might notice that tracker pages have no any advertisement. Tracker exists due to community donations only.
Rather often they run freeleech for movies related to any group, all the movies by chosen director for example, or films devoted to any particular topic. While holidays full freeleech may be gifted. When filling a request user gets some upload bonus. And if filling a staff member request you are to get a special bonus.
