Not always like this but
Acquisition of footage either
a)our own film crew comes in with(H264 when filmed out of studio, 422 LT when filmed in a studio via an AJA kipro), or we buy a show from a production house which usually send it in Prores422
– If H264, we convert to 422 LT into Facilis Terrablock(which is a real pain in the butt for the 6months i have been there, as a side note)
– Offline&Online edit on various Macpros from circa 2009-2010, Blackmagic decklink SDI cards.
– Telestream vantage on terrablock; one compression (mpeg1) gets sent to corporate who approves. Once approved, a homemade MXF compression(i would have to see what it is again, but its heavy compression)
gets sent to our Live studios, which sends it to cable companies.
– We backup the finished shows on external drives, and eventually to LTO5.
Our question was mainly the h264 –> 422LT conversion; it does an OK job, but we wondered if we could make it better using P2, DNxHD, OP1-mxf, etc. instead of 422LT for premiere CC
