try the “ATOMOS – Ninja”(HDMI) or the “ATOMOS – Samurai” (SDI).
I have the Ninja and it works fine!
Only thing ist there is NO Pass-Trou of the HDMI signal.
i think its a problem of the codec.
how ever, try this to solve the problem:
use the AlphaMask of the key and aply it to the duplicated footage (on the dulicate you dont need a keyer!)
dublicate the clip
keep the clips at the same time // synced
remove the key from the lower copy
set the lower clip to get the alpha from the upper one
if it dosn´t work – precompose the upper one
well, all the basic stuff (if i get you right).
– Keyframes
– Import/Export
– Maybe “Adobe Dynamic Link” (depens on…but good to know)
– Masks
– Alpha-Channel (What, When, how?)
– Blend Modes
I think this is the Basic stuff you´l need to get some results for Television.
