5.1 audio in Adobe Premiere Pro CS5

Question

I've got a Sequence (5.1 audio). I checked "Match Sequence Settings" in the "Export Settings" window when I was about to output the final video. The problem now is that in the "Export Settings" it says:
1920x1080......etc......
48000 Hz, Stereo
STEREO? That means I CANNOT OUTPUT A VIDEO WITH 5.1 AUDIO?
If I really cannot output it, then what preset should I choose? Or should I change a software? What about all the movies edited by Premiere Pro?
If I can, then why it says "Stereo"?
Do I need some extentions?
BTW, 5.1 audio in After Effects and Soundbooth?

Answer 1

Harm has given you the reason for the Stereo in the output.
Now, I do not use Soundbooth, but one can easily edit 6-channel (most often seen as 5.1) Audio in Audition, BUT then to output to something that will contain all of those channels, one must choose such an output, say WMA. However, that will limit the uses, i.e. no DVD/BD directly. One MUST use an Encoder, such as the SurCode, to produce a DD 5.1 SS AC3 for the primary Audio stream in DVD/BD (or as a supplemental Audio stream, if one has done a 2-channel primary), or they can do something like DTS, but that can ONLY be a supplemental Audio stream in DVD/BD.
For Encoders, one can easily use the Minnetonka Audio SurCode plug-in for PrPro, a SurCode, or similar, stand-alone Encoder, or stand-alone DTS (fill in any other DVD/BD compliant supplemental Aduio stream here) Encoder.
Good luck,

PS - for DVD/BD, there are only two types of Audio steam allowed for the primary stream - PCM/WAV, or DD 5.1 SS AC3. Supplemental Audio streams are a bit more open, though most will be player dependent. If you do DTS, for instance, your client might, or might not, be able to fully appreciate that.
