Audio - what am I missing here..??

[AJL14]

Simple problem, but no solution at the moment. For some reason, regardless of how I set the audio output when making a DVD or Bluray from a stereo track timeline, I cannot get a "center channel" output. From my screening room sound system (7.1) - only getting "stereo" output to 2 speakers - even when "dialogue" is centered - and in phase. What audio setting outputs a 3 (or more) channel audio - I thought it was "AC3"?

Thanks for your input, guys.

M theater is set up perfectly, and when receiving the proper signal outputs 7.1 with center channel perfectly. I'm actually running 11.1 full output. So somehow the signal to the surround processor out of the EDIUS-made Bluray is not the same as commercial Blurays. On the EDIUS timeline is center channel dialogue (both channels driven equally) as well as stereo FX and Music.

Thanks for your input, but still confusing.

Hi Alan.

If you are working in stereo you won't have a dedicated discrete centre channel. As Andrew is saying, if you want a centre channel you will have to use a mix that uses a centre channel, and encode to multi channel AC3.

If you were working with a surround source mix that was matrixed to pro logic, then this would work if decoded by pro logic. But Edius does not encode the matrix information for pro logic. Bear in mind that pro logic only has limited surround information, and does not encode/decode discrete high frequency channels in the same way as AC3 does.

Edius can supply the discrete channel routing for 5.1 AC3, regardless of forced muting of any channels, again as Andrew is pointing out. But Edius does not have surround panning capabilities.

Basically, Edius is doing exactly what you are telling it to do. The lack of centre channel, or sub and rears for that matter, on playback. Is due to that information not being present in the routing of your Edius audio routing/mix and subsequent encode/decode process.

Cheers,
Dave.

Many thanks guys for your responses. I'll look into that center channel EDIUS capability.

Cheers and thanks again,
Alan

one your timeline is setup correctly as 6 channel, 5.1 etc you will be able to hear the center when playing the timeline by selecting stereo listening in the audio mixer at top right, it is a new option in case you are not sending all channels via HDMI to an amp and from amp to TV

1. in project settings, choose 6 channel or 8 channel
2. in sequence settings, change the setup like this
3. add the audio to their tracks
4. to listen to all channels in EDIUS when HDMI is not connected to sound amp while playing timeline, enable stereo
5. when creating the Blu-ray, be sure you go to Movie Tab of the Disk Burner, and in the audio section, be sure the correct multichannel ac3 is selected

Anton - thanks a bunch. Follow what you advise. I think I did what you advised, but in a slightly difference way. Here's what I did, and you can tell me if it results in the same playback from Bluray.

Only channels which are "center channel are the AV1 and V1 and V2 - all dialogue channels. All other channels - V3 through V14 are stereo music and SFX.

I did change to 6-channel output, and verified AC-3.

I changed the VA1 track and the A1 and A2 tacks all to MONO - since they are the only tracks I don't want spread to any other speaker than the center. All other tracks seem to be spread amongst all speakers as they should be - panning as instructed on the track pan commands. Center stays center, obviously!

So how does this look to you?

Thanks Mate,
Alan

Hi Alan

can I see a screenshot of your timeline and sequence settings, channel map

[antonsvideo]

and I have bad news for you, the EDIUS disk burner can only do 5.1 (6 channel)

Anton - just got home (12:15AM Los Angeles time) from a Toto concert. If you know them, Steve Lukather is my brother-in-law, and it was a grand night! Super concert.

Will send you the screenshots tomorrow.

Alan, line me up some tickets if they come to Orlando :)

[AJL14]

I'll check their schedule, Jerry!

Anton - sorry for the delay. I've had to re-color-correct my pilot for a theatrical preview. Not the same as a "TV" version.

But no matter what I've done - I cannot get the center channel to carry the dialogue (on the AV, A1,A2 tracks). As requested, here are the two screenshots you wanted to see. Any help would be more than appreciated.

Andrew......

Andrew - many thanks for reminding me about that post. I had forgotten. Basically, now, I do understand how EDIUS (7.1) maps to the center channel, and sends the music and effects to L & R channels. However, I'm not clear on how I monitor (visually) which A channels will go to the center speaker. The example showed that A1 & A2 went to L&R, and A3 to center, etc. But I have 3 audio tracks (6 channels since at the moment they are stereo tracks) that are dialogue. How do I see that those 6 tracks (after I separate them into Mono tracks) will ALL go to center channel?

WHOAA HORSE! Andrew, how blocked my thinking must be. Got it! Tracks can be sent to ANY channel - I should have put 2 & 2 together. No sleep has taken it's toll. Many, many thanks.

Again, thanks for refreshing my "gray matter".
Best,
Alan

You're absolutely correct! Thanks again.

Alan.

Are you aware that Edius does not do surround panning?

The multichannel routing is only really useful if you are using a 6 channel stem mix. In which case Edius will encode an AC3 surround matrix from a pre mixed surround mix.

Cheers,
Dave.

Hi Alan

your channel map is only using channel1 and 2, you need to create a mono stairstep using 6 channels because the EDIUS diskburner can only do 5.1 surround
