NO AUDIO : Canon 5D Mark III + BMD Ultrastudio Mini Recorder + Wirecast

Hi Everyone,

Thanks in advance for your time and precious advices.
And sorry if there is any spelling mistakes, english is not my first language.

So…

I often use Wirecast with the Mini recorder and the ATEM Production 4K 1/ME . Everything has always worked fine so far.

I now need to make a mobile live stream with my 5D (1.2.3 firmware) and i was thinking about using 5D + Hdmi cable + Mini Recorder + Wirecast.
I succeed to see the image in Wirecast but no audio (except from my MBP laptop). It looks like that there is no audio sent trough the HDMI.

Someone did face this problem or know how to fix it ?

I think i can try to use an USB microphobe directly on my laptop… but i'd rather prefer a microphobe on my DSLR of course.

Thx ☺

Jérôme

First make sure you are using Blackmagic driver 10.8.6 which is the current version.
Then check in Blackmagic Media Express to see if you get audio from the camera. It's quite possible audio is not being sent through HDMI but checking in Media Express could confirm that.
If there's no audio in Media Express you may need to see if there's a camera setting that enables that.
If there is no way to send audio over HDMI than you will need an external audio source (mic) to send to Wirecast separately.

Hi
I think its highly unlikely that a Canon mk anything will pass through audio, let alone any audio you'd want to use!
Generally on these still cameras with video function tagged on, the audio is the very poor relation both in terms of interface and quality (which is a real shame)
lack of proper audio inputs (not mini jacks) metering, quality pre amps, monitoring - all very poor

You'll need to look at taking the audio a different way, and then looking closely at sync at they are bound to be miles apart.
