We have just been testing he levels in and out of the decklink extreme: The SDI levels are perfect, and component out as well.
But the component input is about 25% too low on level and chroma. If we push the proc amp settings to maximum (+1.8db), it reaches about 95% of PAL white when feeding it 100% color bars.
Has anybody actually confirmed the input and output levels on a scope like we did tonight? When we are looking at the input through the capture tool, we can compare FCP’s built-in waveform/vector scope with the hardware Waveform/Vector on the output of the card, and they seem to correspond pretty closely. But the analogue input level that is this low is shocking.
