Audio Output selection

[2Gunz]

I have the SCS Professional Plus license.

Im using a Scarlet 18i20 as an audio device.

I have it set up and I can tone the channels as I think they should be.

When I add a video clip my only options are "default" and "mute audio".

How do get the audio to go to say output 4?

Thanks!

Chad

Select Editor.
Select the top line in Editing to see production properties
Select devices
Select video audio
And add physical devices

I hope this helps. See the attached image.

Thats a step in the right direction.

However that lets me change to different hardware devices.

I want to use the same hardware device for all the outputs, but use different channels on that device.

Thanks!

Hi 2Gunz,

Which SCS release you have?
I old releases, the audio for video device was determined by windows default audio device.
In this case, you must change the default audio device in windows setup.

If you use the last SCS release you should be able to select the same physical device for audio and for video. And you should be able to select any of 20 output for video and for audio and this outputs can be the same or not.

I have a Scarlett 18i8 at home and a 18i20 at theater. In the theater I send daw 1, 2, 3 and 4 to adat outputs 1-4 because I have the scarlett connected to the mixer through adat.
I use outputs 1,2,3 and 4 for audio and the same 1 and 2 outputs for video.

If you do not find the right way, this afternoon (GMT+2) I will send you images of my setup at home. I cannot go to the theater this month.

Lluís

Hi Chad,

From the help file's "Production Properties - Video Audio Devices" topic:

"If you have selected TVideoGrabber (TVG) as the Video Playback library in Video Driver Options then you can select any available DirectSound output device for your video's audio. Although each video cue only lets you choose one audio device, you can use different audio devices for different cues, so in this tab of the Production Properties you can define your Video Audio Devices. If you are not using TVideoGrabber then you cannot choose the audio output device - video audio is always sent to the Windows default sound device."

So the first thing to check, if you haven't already, would be whether you're using the TVG library.

On my system, when I drop-down the Physical Device box it shows me a list of channel pairs available on my Behringer interface, as well as the the default Windows device, so that single drop-down is used to select both the physical device and channel pair, like this:

For me, the awkward thing about this is that I can only select stereo pairs; if I want to send video to a mono FX channel then the adjacent audio channel must be left empty, so it's wasted. Fortunately I have channels to spare.

For you, it's a bigger problem if you don't see a list of choices similar to this. Mike can probably give us more insight, but the list of devices and output channels displayed here is probably limited by the capabilities of TVG and/or DirectSound and/or your sound interface's device driver. If your Scarlet interface has a configuration screen you might want to take a look at it. As the help states, SCS uses DirectSound for video-audio output, so the driver might have options affecting this that are separate from the ASIO configuration options. Alternatively, it might even have totally separate drivers to install for DirectSound versus ASIO.

Hope this helps,
Tim.

I do not understand anything.
I was able to do what Tim shows, but not now!!!!

At the moment I have the same problem that Chad has.
I can test the 8 outputs from windows audio driver setup but Directsound publishes one stereo channel only.

My screenshot was not from the latest version of SCS - I still have 11.6.0 installed at the theatre.

I'll try 11.6.2, hopefully tonight, in case this is a recently-introduced issue.

Tim.

[2Gunz]

I am using TVideoGrabber as the video render.

All I get is the single option.

Any ideas?

Thanks!

Chad

Lluís,

I completely missed your reply.

Im using the latest version of SCS.

Any pictures or hints you can buy me would be great.

Thanks!

I just updated my theatre computer from 11.6.0 to 11.6.2 and it's still showing the list of stereo pairs as shown in my earlier screenshot.

Another thought... You might try switching from the 32-bit version of SCS to the 64-bit version, or vice-versa, and see if that makes a difference. If it does make a difference, it could be that you don't have the appropriate 64-bit or 32-bit Saffire drivers installed (this is just a wild guess - I don't have a Saffire interface so I don't know what choices the driver installer gives you).

Tim.

[2Gunz]

Would it be possible to get Screenshots of anybody setup? Particularly with a larger scarlett?

I feel like Im missing something very stupid.

Thanks so much for your help so far guys!

I ran into this issue when I was working a show recently using my SCS laptop via USB connection to an Allen&Heath Qu 16, which acted as the sound card. The Qu 16 driver is ASIO and as such any video cues could not access it. After talking to Mike about it I found out that TVG doesn't support ASIO drivers - it only supports DirectSound drivers as the above quote from the Help file states. So I was only able to use my onboard sound card for the video audio output and not the Qu 16. Even when the Qu 16 was selected as the Default Audio Device the video audio couldn't be routed through it because of the ASIO driver. It had to use the onboard DirectSound driver only.
This was using 11.6.2 Professional Plus 64-bit. But the computer and SCS had no problem using both the onboard sound card and the Qu 16 to play back cues in the same show file. I could still use the Qu 16 for any audio cues. So I suggest to the OP that the workaround right now is to use your computer's onboard sound card output for the video audio, patch that to wherever you need the audio to play and then use your Focusrite for all the audio cues outputs.

From postings in this topic, it does seem there's some issue with the audio output selection for video audio. ASIO is definitely not available yet for video audio (OK for 'Audio Output Devices', just not for 'Video Audio Devices').

Since I'm not able to reproduce any such issues myself, could I get diagnostic files from users who have encountered problems selecting their required video audio device(s)? These diagnostic files should be created in a run that has the required audio interfaces connected, and should preferably be with SCS 11.6.2. You can create this file by selecting 'Create Diagnostic File' from the drop-down menu displayed when you click the Help button in the main window. The file will be saved in a folder named "SCS Diagnostics" under "Documents" or "My Documents". Please email me the diagnostic file(s) together with a description of what video audio devices you expected to see but couldn't access (or whatever the problem was).

Hi all,
It seems a Focusrite issue.

Answer from Focusrite support team:

Hi Lluís,

Thanks for your enquiry.

Unfortunately there's no way to expose more than the 1st two outputs of the 18i20 when using non-ASIO applications on Windows. The beta driver you've mentioned allows the device to be used for surround sound playback from applications such as Media Player/VLC Player, it does not allow you to select additional outputs from a DirectSound application I'm afraid.

I've passed your desire for this sort of functionality over to our driver development team however I can't, at this stage, confirm whether or not this is likely to happen or give any kind of timescale.

If there's anything else I can do for you then please let me know and I'll be happy to help.

Mike thank you for the reply.

I sent you an mail with the diag file.

Im starting to think that this is a Focusrite driver issue.

An audio only file works as expected on multiple outputs.

Video I can only get it to show L and R as an output.

Im willing to buy whatever, I just need to get it fixed.

So...........

What USB device should I get to do multiple audio outputs when playing back video?
Im going to need 6 outputs and one live input.

Thanks!
