How to Stream on Zoom with Wirecast - Audio Troubleshooting Answers

Hello,

I recently was tasked with streaming from wirecast to Zoom by a client for some online webinars. 

I had a great deal of difficulty getting the audio to work with a media file but after nearly 3 days and 9 phone calls/15 emails, I finally fixed my problems and wanted to share with you some steps to successful audio in Zoom.

First, you want to open wirecast before doing anything with Zoom. 

Once wirecast is open you want to go to the virtual camera out and select HD720p (or desired canvas size) and also make sure the Virtual Microphone is checked.  THIS IS SUPER IMPORTANT.  Then select START in the virtual camera out.

Then you want to head over to the Zoom website.

CLICK MY ACCOUNT then on the LEFT side go to MyMeeting Settings

Scroll down to where it says InMeeting Advanced and make sure (Allow users to select audio in their client settings) & (Allow users to select original sound in their client settings) are both highlighted BLUE.

THEN

UNDER ACCOUNT MANAGEMENT ON THE LEFT you will need to do the EXACT same thing as above.  Select both (Allow users to select audio in their client settings) & (Allow users to select original sound in their client settings) so they turn blue.

THEN

You must log out of zoom, and log back in.

THEN

Open the Zoom.us application and select SETTINGS in the upper right side.

UNDER THE AUDIO TAB (ORANGE HEADPHONES) 

Make sure the Wirecast Virtual Microphone is selected under Microphone section

Check the enable stereo box AND Allow option for using original sound from microphone in meeting

THEN

When you are streaming in Zoom, make sure you select the Wirecast Virtual Microphone as well as the Virtual Camera.

LAST STEP is on the stream screen in zoom, on the upper left will be a drop down menu and you want to select (Allow option for original sound)

Hope this helps others.  It would have saved me about 20 hours if this was available when I needed it.

Happy casting!

  • Thanks for this thorough post. We have been using Wirecast and Zoom to record videos. We've had everything working a while but the local MP4 is often not high quality when we bring in a guest through Zoom and the audio is out of sync by .5 - 1 second. I've verified it is not an issue with the internet connection. Will the settings you posted help with these issues?

  • Hi Heather. 

    You should see improvement by going through my workflow.  It's been a bit now, but I do remember having some issues with quality of video and once I worked through all of this, I saw very clear streaming.  It's never going to be as good as what you would see on a buffered service, but still solid.

  • since this thread is zoom.us. i hope i am posting in the appropriate place.

    im using a shure X2u with a condenser headset mic.  a dslr camera and a magewell capture pcie card for video only. 


    The sound levels are coming through ok on other screen record software (camtasia), but when i record via wirecast it goes louder and quieter as if there is some auto gain on. I see there isnt that facility in wirecast, I record live webinars (zoom.us) and the recording from wirecast has this problem not only in the recording but also in the output to the webinar software as viewers have commented.
    For recording purposes i can edit with a noise leveller but its not ideal as the sound quality isnt great.

    tried different mics, and also another X2u unit but still has same problem.

    using wirecast 12.0.0 
    on windows 10 desktop with decent spec for wirecast and  dell xps15 32ram i7 7700hq cpu

  • john Software like Skype, camtasia and others are designed for low control and as such use an auto gain system for their inputs. Wirecast gives you the base raw audio input from the device(s) as to ensure that there is no artificial noise or raised sound floor. I would recommend checking your system levels of the input and adjusting according to that. On Windows, this is your sound controller settings. On MacOS you can see the levels of an input in the sound preference pane and (I think though I cannot confirm at the moment) the midi utility application.

    You will likely need to simply increase the device's input level.

     and update to 12.1 or you may run into other issues.

     Please look at Wirecast output meters. That's sending to the encoder.
    Preview will show you what's happening to the shot before you take it live.
    Each audio device, as a shot, also has individual meters you can check.

    As a matter of course, always check each point in the signal chain.

  • Wirecast Pro Audio Mixer has Dynamics control whose equivalent might be automatically occurring in other software. That's why it's best to check in a known auto program that does not provide automatic processing.

  • well, thats the thing im not using any other software. its a usb sound in direct to wirecast. it doesnt go through anything else before wirecast other than the driver.

  • john But you are comparing your experience to other software which may handle the audio differently. Other software may be compressing or normalizing the sound whereas Wirecast is getting the sound direct.

     Which may be processing the audio differently so it's not an accurate comparison.
    You need to look at the meters in Wirecast (and they can't be compared to other programs which may use different calibration and ballistics).

  • ah yes, i see what you mean.  the problem is that wirecast wasnt recording with this problem all the time. The reinstall to 12.1 version has stopped the issue for the moment though. i only use it three times a week so need more time to ensure the issue has gone away.
