No 4ch output over SDI?

[Tim Irwin]

Just figured it out. For the benefit of anyone with the same problem, If you change the settings in the audio output tab after you have edited into it, it has no effect. After I created a new seq with the appropriate settings and pasted the contents of the original seq into it, the 4ch output worked.

Did you forget to turn off the down mix button on the audio mixer?

If it worked, great, but I don’t think you needed to do that.

Change the audio settings on the A/V Settings, but then you need to do cmd + 0 [zero] on the sequence in your bin and change the audio settings in the audio tab there too. then set the audio track to the proper channel by ctrl + click next to the track light [sorry, Avid term] to designate the channel patch.

I’ve always wished Apple would change this dopey procedure in a next version of FCP.

Actually that’s incorrect. You can change the Audio Output tab at any point during your edit. I output 4 channel shows all the time and generally leave the timeline as a 2 channel mix until we’re ready to master. Then I switch the outputs to 4 channel and assign the audio tracks accordingly. You do not need to create a fresh timeline to do this.

Sounds like you changed the overall preference instead of the settings of your sequence.
Changing the preferences changes the output for all NEW sequences, but has no effect on the existing ones.

Unlike Avid, FCP can have multiple projects and sequences open at the same time…and each open sequence can have its own audio output setting.

You can also setup a 4 channel output sequence, then simply hit the downmix button on the FCP audio mixer and monitor two channel. Super handy for four channel mixes and two channel monitoring.
