Exporting 4 Audio Tracks to Digital Betacam deck

[Shane Ross]

How are you exporting? What capture card?

Unfortunately I don’t know about the card. It’s a broadcast magazine on cinema and they’re working with digital betacam and FCP 5. That’s all I know…

Hope this works for you. I knock out a four-channel master weekly for a one-hour show without any problem. First, you must have an IO that can handle four channels of audio out to the deck. I use the AJA Io, and have sent four channels to a D-Beta via AES/EBU, and to a BVW-70 with four analouge channels.

Under the sequence settings pull-down menu go to audio. Switch from two channels to four, make them dual-mono not stereo. I set them to 0db instead of -3.

In your timeline control click or right click on each audio timeline and assign it to a track. If you started the project in stereo or a two channel default, your four tracks will default to 1&2, 1&2 instead of 1,2,3,4.

In my bars & tone at the head I build two seconds of tone on cnl 1, then 2 on 2, then 2 on three then two on four, then tone across all four. This way I can see the four channels hit the meters on the deck and be confident that I have clean seperation for the stereo mix on 1&2 and the M&E on 3&4.

Let me know if this works for you…
