ok-this might be a issue with the multibridge
we have 3 systems with decklink extreme cards. in the system preferences bmd control panel we have a third tab named proc amp which has been there for several years (yes we are on the latest everything on mac/fcp/bmd).
this is for adjusting input levels when capturing analog component.
I did a quick search on the bmd site and did not find any reference to it, although at one time it was a hot issue on the cow as there were inconsistent video levels from card to card during capture via anolog component.
I would repost as “component proc amp” or something and mention Kristian’s name in the post so he sees it for a quicker response.
fyi, I’ve never actually used the feature since we only capture sdi or composite analog.
