Streaming 4k to youtube and other locations

Hi i thought that 4k uploading was permitted on youtube, but i can't find out how to do it with wirecast. Could you please help?  Where/how can i stream to youtube in 4k? The attached screenshot seems to show a max of 1440p, am i missing something?

 

Also, this triggered another, bigger question about i have about wirecast. Could you please help with this too:

 

 Is it possible to simultaneously upload different sources to different locations? And apply different effects to different locations? Here's my use case:

 

I stream using two 4k webcams, both with green screens in the background. I want to stream/save this in 3 ways:

 

a) a split screen shot of both cameras. this would go to streaming services live for viewers (and, as i understand, would be converted to 1080p because most services dont permit 4k). The green screen would be chroma keyed out and filled with another visual on this live stream. I would send this to a service like restream IO to live stream to many platforms.

 

b) save/stream the unedited, 4k footage from camera 1. This footage would have full resolution and would not have the green screen chroma keyed, so that i can use and edit this footage later with more freedom. I would want to stream this to a private youtube account, that i can use/dl from later.

 

c) save/stream the unedited, 4k footage from camera 2 in a seperate  youtube stream/upload/account. This is the same thing as described in B, but i want a seperate video that i can use/edit for the second camera.

 

Does that description make sense? Am i misunderstanding anything? Is it possible to do this the way that i am imagining?

 

Thanks, Dan

  • LP Have any YouTube 4K presets for Wirecast been created since this post? Thanks.

  • Christopher Harris Not yet.
    Given the bandwidth requirements for YouTube 4k 30fps
    Video Bitrate Range: 13,000 - 34,000 Kbps
    and 4k 60fps
    Video Bitrate Range:  20,000 - 51,000 Kbps

    Can you describe the scenarios where you would live stream at 4k and to an audience that can view 4k?

  • Thanks Craig,
    Scenario: 360 Live Stream. Here's an example: https://youtu.be/o3_byIkXF7Q?t=131

  • Christopher Harris Wirecast doesn't yet officially support 360 Live Streaming. If that's the use case you should request 360 support.

  • CraigS Wirecast was used to stream the broadcast I mentioned above to a Wowza server which then passed it along to YouTube Live and Facebook Live. This was a 3840x2160 30p stream at 19 Mbps.

    Subsequently, I've been successful at testing at 30p to YouTube Live. Wirecast doesn't HAVE to support "360 streaming" to do this, just 4K. YouTube (and Facebook) takes care of the 360 part by a simple check box.

    So, all I'm trying to do is stream 4K video to YouTube. What I'm trying to learn from this forum is some good settings to use to accomplish that. I've had success with 30p, but not 60p.

    If there are no "official presets," fine. Are there any presets anyone (Telestream OR end users) have come up with to successfully stream?

  • Christopher Harris I've seen other reports that using Wirecast for 360 results in a seam. In other words the use case is an unsupported use example even if it does work.

    You can certainly make the request but a supported use case might be better example.

    You can create a custom RTMP encoder setting and use that to stream to YouTube.  YouTube has recommended settings.

    LP  can document a request for 4k preset for you.

  • CraigS Thanks Craig. I can confirm the seam you mentioned appears in the broadcast I provided above. The same seam does not appear in the recording.

    They must not have known that the seam issue was related to Wirecast because they TRIED to fix it with the 360 production switcher they were using and then ultimately placed the seam along a natural break in the scene.

    So, what would be my next step here? Or, since it's an "unsupported use," is there even a next step? Thanks.

  • Christopher Harris Next step would be a feature request to officially support 360 streaming. LP  can do that for you. That would make 4k much more valuable in this particular workflow.

  • Still no preset for UHD streaming to YouTube.

    Why not?

     Good Question
    YouTube support live stream up to 4Kp60
    Our internal reference for this is WIRE-13149

    I'm investigating.

  • Wow, requests for 4K presets apparently sent in 3 years ago and STILL not included in Wirecast! Not that it's impossible to create a preset, but I would much rather it be made by someone who knows a bit more about the requirements than I do.

      Jerel Peterson We have a feature request vote for native 4k support. Please do vote for it. I believe it's tied for the 8th ranked feature request at the moment.

  • Vote Added. I would think this would be one of the quickest/easiest requests to do. Does it really have to wait until it gets in to the top 5 (or whatever) before it's added?

  • Last time I tried,  I could not even create a YouTube UHD (which is not the same as 4K) preset.

    Pathetic.

    This type of failing is why people are bad mouthing Wirecast in public forums and online meetings. 

    And the fact that 14 doesn't run on my cheesegrater with High Sierra makes me really unhappy.

      Robert Ober I'll see what's holding up prioritization.

       That is four operating systems back Mojave, Catalina, Big Sur since then and macOS changes mean we need to make changes to take the best advantage of new code while dropping older code which can become problematic.

    • CraigS I don't buy it.   A program can query as to which OS it is on and adjust itself based on the result.

      Lazy programming has become the rule.  Lots of folks in the creative spaces still running cheesegraters and other old Macs.  I have a 2018 MacBook Pro on Mojave to keep from having issues with Media Composer.  Only in the last few months has Media Composer become stable on Catalina.  OS upgrades are not usually necessary or these days offer anything compelling for most users.  Newer is not necessarily better.

     That depends on the program and the market. Apple has made changes in both the OS and hardware which require us to make significant changes making backward compatibility more difficult.
