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!

    Sorry about you're experience with Gear 110.

  • 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!

    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.

     

    Thanks!

     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!

     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). 

    Like
  • 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.

      CraigS There is a crash that is consistently happening in Wirecast that I am hoping you will be able to reproduce on the Mac Pro y'all ordered.

      I am running the latest version of Wirecast, the latest version of Mac OS, and just updated to the latest drivers for the Blackmagic Design DeckLink Quad HDMI Recorder 4K PCIe Capture Card.

      Basically, all sources that are 1080p or 720p work flawlessly. Anytime I have a source that has a higher resolution than 1080p, Wirecast either crashes 1) when I open a document that has the included source in the file or 2) if I create a new Wirecast document and go in to add the HDMI source from the Blackmagic DeckLink, the program crashes.

      Please let me know if you're able to reproduce this. I have a very high degree of confidence this is a Wirecast issue as I am able to look at the sources in BlackMagic MediaExpress just fine even when inputting a source with a 4K resolution.

      Thanks!

      David Meg Wirecast 13.1.3, macOS 10.15.6, BMD driver 11.6 or 11.5.1?
      Can you be specific about the frame size and frame rate of your ingesting?
      It sounds similar to an issue we've seen.

      CraigS Running - Wirecast 13.1.3 (82.d9eb0b75), macOS 10.15.6 (19G73), BlackMagic Driver 11.6.

       

      Yes, I can duplicate the issue with an output from a PC spitting out 2560 x 1440 and an iPad with the resolution 2732 x 2048.

      David Meg Just a hunch but I suspect the frame sizes are at issue for Wirecast.

      Have you tried a true UHD frame size which is 3840 × 2160?

      CraigS Your hunch may be correct. I just plugged in a 2016 MacBook Pro and configured the output to 3840 x 2160. I then created a new document in Wirecast and manually had to select the 4K 2160p30 option under Video Format.

      The output and input using this 4K size works correctly. 

      So now that is established, is the Wirecast crash being driven by other resolutions exclusively?

      Thanks for your continued help, Craig. As far as the support assistant file, what specifically are you asking? I did not save the report that I'm aware of.

      Have a great evening. Thanks!

  • David Meg How did you find the Mac Pro with Wirecast? I am upgrading from a 2017 Top Spec 17" Macbook Pro and am considering a 16core with?GB memory (starting with 32GB and upgrading myself) and either single or duo Radeon Pro W5700X. I'm running 4 x 1080p streams and would love to be able to ISO records all 4 at once using my Blackmagic Quad PCIe card. Are you happy with your decision?

      Troy Grech The Blackmagic quad HDMI PCIe card certainly is quirky, but I've found that is a perfect word for *all* the Blackmagic products I've ever used. It works fine other than a crash that is happening in Wirecast with 4K sources. (see the comment reply I just said to CraigS  above)

      I really like using Wirecast on the Mac Pro so far. Once I am able to use it fully with 4K sources, I will be quite happy. I think, from an overall (non-Wirecast) perspective, my favorite thing about the Mac Pro is how quiet it runs CONSISTENTLY. When I say there is very little fan noise at all, even that may be not giving this machine enough credit. It is *quiet.* Excellent for a creative studio environment.

    • David Meg Thanks soo much for the Update. What CPU usage are you seeing whilst stream? Can you ISO rec 4 x Cams as well as stream and record the feed? I'm sure that would stump the machine and cause errors/ dropped frames or is the MacPro up to the task?.

      Troy Grech Let me get this pesky crash issue solved and I'll be able to give you a more precise answer to all of this soon hopefully. So far, the Mac Pro has not flinched with streaming/recording the feed and doing ISO.

  • Looks like we know what we need to change to avoid the crash but it will be after the next release though as there's some work involved that won't be done in time for this release.
