Multibridge HD will not embed AES channels 5-8
A client sent us ten hours of DA88 tapes with 5.1 and stereo (8 channels total). I was excited to finally get a chance to capture multiple audio tracks at once, cutting the capture time from 40 hours down to 10 hours.
My DA88 deck is feeding 8 AES channels into a Decklink Multibridge HD, which embeds the channels accordingly into the SDI, which then goes into a Decklink Extreme.
I cannot get Final Cut 5 or the Blackmagic Deck Utility to see channels 5-8 no matter what. Final Cut will only see 1-4. All 12 channels are available in the log and capture window, and 1-8 are all turned on, but I only get levels on 1-4. Using the Multibridge Utility (1.51), I can re-route 5&6 or 7&8 into either 1&2 or 3&4, and I do indeed hear what’s on those channels. So I know the multibridge is seeing all 8 channels, but it doesn’t seem to be sending them. Or perhaps the Decklink Extreme is only picking up 1-4.

Hi Sean,
What format of video are you embedding the audio into?
-
NTSC from a Digibeta.

Any info? The situation hasn’t changed. I’ve tried it on another system, one that has a Decklink HD Plus. Same thing. Channels 1-4 only.

Respectfully I have to ask, am I speaking to deaf ears?
I got a hold of a DVCPro HD deck and plugged the component HD analog into the multibridge. When I do this, I can indeed embed all 8 tracks.
So it appears that if the Multibridge is in “SD mode”, then it will only embed 4 channels. I must be in “HD Mode” to embed more. Needless to say, this is a problem for me and this limitation was never mentioned anywhere. Hopefully it’s an overlooked bug that can be worked out. I do a lot of jobs where I need to capture video from a Digibeta and have my DA88 chasing the timecode so that I can grab video plus 8 channels at the same time.
These are not wedding jobs. Digibeta + DA88 is what the home video department of a major studio sends us all the time. Being able to capture everything in one pass is one of the major reasons we bought a Multibridge and upgraded to FCP 5.
