Wirecast Pro on New Mac Pro

Hi. I'm looking into really stepping up our Wirecast setup.


I currently have a Wirecast Gear 110 unit and have overall been quite unhappy with the performance of the unit especially since upgrading to Wirecast version 13. We will not ever buy another Wirecast Gear unit as the current unit runs very loudly (fans in the unit are annoyingly loud) and it's just been a bad experience overall. With that said, we are happy with the Wirecast software and look to move forward on the Mac side as opposed to the Windows side. A few questions:

1) I know we are super early in this process as the new Mac Pro has just been released. Has anyone tried running Wirecast on the Mac Pro? What is the expected performance? I'm assuming really great considering it has a 3.5GHz 8‑core Intel Xeon W processor and Radeon Pro 580X GDDR5 memory. 

2) We need two quad HDMI capture cards for a total of 8 HDMI inputs. While I only expect to use 5 or 6 of the inputs, I want to have room for expansion at a later date. Any recommendations of the capture cards that will work best in the new Mac Pro with Wirecast?

Thanks. Have a great day!

  • We're getting one it to test.
    Sorry about you're experience with Gear 110. 

  • CraigS Any update on this? Thank you.

  • David Meg Still waiting on our Mac Pro.

  • David Meg Just tested on the base configuration. No issues. Works as expected.

  • CraigS Thanks for this update. I appreciate it.

    Could you clarify a bit as to how many and what types of sources were tested? Thank you!

  • David Meg I don't have a detailed test list as of yet. I'll see what I can find out.

  • CraigS Thanks Craig.

    I continue to research a new configuration for a machine for Wirecast Pro. I think we are going to move forward with a Mac Pro, although I do have a few clarifying questions.

    I plan on running Wirecast Pro with up to 8 HDMI inputs utilizing this capture card (https://www.bhphotovideo.com/c/product/1464918-REG/blackmagic_design_bdlkdvqdhdmi4k_decklink_quad_hdmi_recorder.html/overview) times two. In other words, have two of those PCIe cards in the Mac Pro and then the 8 HDMI inputs running into them.

    With that in mind, what processor configuration would you recommend? Would the base model suffice or should I step up to the 12-core Xeon? Same question with graphics... Will the base 8GB suffice or should I step up to the 32GB HBM model? I'm not as concerned about storage/SSD or RAM as these can be easily upgraded.

     I always believe in over buying. You never want to buy "just enough" only to find as you add things, you're short on resources. You can always upgrade RAM and, with the Mac Pro, even the GPU. You can't upgrade the processors though. There may come a time when you want to move from HD to UHD sources, for example. 

  • CraigS Another question I've searched the forum for to no answer is: Does Wirecast directly benefit from adding the Apple Afterburner card? I see that it helps with video encoding for certain types of videos, but I am not clear as to if Wirecast can tap into this card? I will be using this machine exclusively for Wirecast.

    Thank you!

  • David Meg said:

     No. I don't think Apple had provided the API/SDK for third parties to use yet and even so I'm not sure how it would benefit the functions we use vs those used by software such as FCPX and Motion (users it's targeted for). 

  • CraigS Apparently the Afterburner card is exclusively for DECODING and not encoding. I ordered a beefy (16-core processor, 32GB Vega graphics card) Mac Pro for our use of Wirecast. I will report with results here in a few weeks once I get everything up and running.

  • David Meg Looking forward to hearing your overall evaluation.
