Uhm, you do realise a Telesync is a cam in terms of video source? It's only the audio that distinguishes it from a cam. Actually no, you probably dont know that. So here you are, I'm educational as well as mocking.
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.
So your weekend viewing consisted of an unfinished workprint of a film with missing scenes, missing effects and blurred/cropped AR (Hostel 2) and a telesync cam (Evan Almighty). Sounds like fun!
