Audio Questions

[Andy Tejral]

I just bought me a Zoom H2 audio recorder. It will record surround audio via two stereo wav files. There is also a marker function--hit a button and it drops a marker into the file.

I was trying to determine a workflow and ran into some obstacles.

First, it doesn't seem that Edius will do anything with the markers? I see them in Vegas and Sound Forge but not in Edius.

Second, Mike Downey assured me that I could work with these surround files and export multi-channel audio. I poked around a bit and can't find a way to do it. Some of the export options--AC-3 for example, promise 5.1 on the configuration page but when you go to actually save the file, stereo only.

I was expecting that I could export a multi-channel wav but no go.

You can export multichannel wav from a multichannel project.
The only thing is that you have to use a project which is multichannel out enabled. For 5.1 you have to use a 8 channel project.

I just checked the project settings and it says I have 8 audio channels. I only have 4 assigned. A1 = 1/2 A2 = 3/4.

I'm missing something, somewhere...

[SRsupport]

yes. you have to map the the hard-out for channels.

I would also use dedicated channels for my audio.

Go in to the seqence tab. Sequence settings and map the hard out for the audio channels then when you export you will have a multichannel wav or 5.1 decdicated audio.

The only 8 channels project is DVCPro, we need 8 channels in other HD preset also or am I also missing something?

[SRsupport]

These might help.

The only 8 channels project is DVCPro, we need 8 channels in other HD preset also or am I also missing something?

With the Hd storm there are 8 channel projects for:
AVCHD
Infinity
HD D5
AVC Intra 100
HDcam-SR
HDV
AVC Intra 50
HDCAM
XDCAM
DVCPROHD

What are you missing?

[Khoi Pham]

I'm on NX, the only 8 channel preset is OHCI DVCPro HD and AVC Intra, there are no 8 channels for 1920X1080 or 1440X1080 nor NHX-EX DVCPRO HD. I have been importing audio into these preset that has 8 channels and it is a pain.
On another note, I only have a stereo file to create 5.1 and so it is fake, but this way my client don't have to switch their receiver to matrix to get all channels going, the less button push the better for them, that is why I'm doing this, my other work around is to use ProCoder, it will make 5.1 out of stereo file, but ProCoder it slow as a turtle, but let say I have 6 discreet channels, how do you assign front left, center, front right, suround left....? In the mapping area, there are only left and right.

[Andy Tejral]

OK, I think I get it now. You NEED to have 8 audio tracks.

I just had two stereo tracks and was assigning A1L-1, A1R-2, A2L -3, A2R-4. I really don't even need to hear the surround tracks--just need to cut them the same as the vid and front audio.

I'll give it a go in a little while.

[Andy Tejral]

And I'm just out of luck on the audio markers?

[SRsupport]

I think so. ...but I am not sure.

[Andy Tejral]

Oh, and thanks for those PDFs. I would never have gotten there by myself.

[SRsupport]

You are welcome. :)

Nice work on the pdfs!

Thanks Pat. I hope they are useful to many in the EDIUS community.
