usually used in reference to a movie, a tc or telecine is a professional grade
copy of a film that can usually be acquired before the dvd has been released, at
near dvd quality.
it is made with a telecine machine, which are professional grade machines that
some movie producers use to make copies of their films, and are thus very rare.
a more common type of pre-dvd release is a ts or telesync. these copies are
usually made with a professional quality camera filming a screen playing the
video. they are basically high quality cam releases.
pre-release movies are notorious for being labelled wrong... such as one
that is actually a ts labelled as tc.... and often a regular old cam being
labelled as a ts (this happens more than 50% of the time)..
telecine
a telecine machine copies the film digitally from the reels. sound and picture
should be very good, but due to the equipment involved and cost telecines are
fairly uncommon. generally the film will be in correct aspect ratio, although
4:3 telecines have existed. tc should not be confused with timecode , which is a
visible counter on screen throughout the film.
telesync
a telesync is the same spec as a cam except it uses an external audio source
(most likely an audio jack in the chair for hard of hearing people). a direct
audio source does not ensure a good quality audio source, as a lot of background
noise can interfere. a lot of the times a telesync is filmed in an empty cinema
or from the projection booth with a professional camera, giving a better picture
quality. quality ranges drastically, check the sample before downloading the
full release. a high percentage of telesyncs are cams that have been mislabeled.
cam
a cam is a theater rip usually done with a digital video camera. a mini tripod
is sometimes used, but a lot of the time this wont be possible, so the camera
make shake. also seating placement isn't always idle, and it might be filmed
from an angle. if cropped properly, this is hard to tell unless there's text on
the screen, but a lot of times these are left with triangular borders on the top
and bottom of the screen. sound is taken from the onboard microphone of the
camera, and especially in comedies, laughter can often be heard during the film.
due to these factors picture and sound quality are usually quite poor, but
sometimes we're lucky, and the theater will be fairly empty and a fairly clear
signal will be heard.
