TELESYNC (TS) -
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.
除了使用外置的音源（一般是影院座椅上為聽力不好的人設的耳機孔），TELESYSNC(TS) 和CAM的標準是相同的。這個直接的音源并不能保證是好的音源，這是它因為受到很多背景噪音的干擾。很多時候TS是在空的影院錄制，或是用專業攝像機在投影室錄制，所以圖象質量可能比CAM好。質量的起伏可能很大，在下載前最好查看SAMPLE。很大比例的TS是從CAM錯誤標記成。
TELECINE (TC) -
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. A great example is the JURASSIC PARK 3 TC done last year. TC should not be confused with TimeCode , which is a visible counter on screen throughout the film.
TELECINE (TC) 使用電視電影機從膠片直接數字拷貝，其圖象和聲音質量應該很好。但由于使用的設備和費用很高，TC很少見。通常會使用正確的高寬比，但有時也有4:3的TC。去年的侏羅紀公園III是一個很好的例子。不應將TC和TimeCode(時間碼)混淆，時間碼是一個在屏幕上可見的計數器。
