A 'professional' bootleg camera job with direct sound. Wherein a VCD pirating group sends a cammer to a cinema with camera and wireless mic's. Cammer attaches wireless mics to speakers, videotapes the image off the cinema screen and goes and rips a/v to his computer and encodes and disseminates through the internet.
Asian versions of telesyncs are called silvers
Non-direct sound or overall shitty quality telesyncs are often refered to as cams
Centropy and TCR release some of the best telesyncs on the scene right now. FTF and UMS release the worst.
