SPX-GC LIVE Cloud Demo
SPX-GC Cloud demo instance has some differences to a local version:

  • Changes made within demo are reverted couple of times a day automatically
  • Open folder -commands do not work (no file system access)
  • You cannot modify or add HTML templates (no file system access)
  • You cannot modify custom command functions (no file system access)
  • To test CasparCG playout, your CasparCG server must have a public IP-address, so the cloud based app can access it. Also you need to unzip to your CasparCG's templates/smartpx -subfolder.
  • FAQ
    Pricing and business model?
    GC is open source software and is free to use. The business model with GC is in creative services and support. So after testing the system if you would like to integrate GC with your other production systems and devices or would like to implement custom graphics package and branding get in touch.

    Who is it for?
    GC might be a good solution also for a single streamer, but is mainly aimed at professional production teams, such as OB trucks, control rooms and for publishers or organizations who are constantly producing live broadcasts and streams or other web based live events or television broadcasts. SDI and NDI video can be produced with SPX-GC by using CasparCG as a playout server.

    How do I use GC with my streaming software?
    Most streaming software (OBS, Wirecast, vMix, XSplit) supports a browser as a source. Once installed, GC provides a URL address, which will be used as a transparent, fullscreen source ontop a video and GC can then control multiple graphics layers on that overlay window in real time for full framerate and full quality, animated and dynamic graphics such as tickers, lower thirds, lyrics and titles.

    How can I submit my feature request / bug?
    Please do so! For us the most convenient way would be the feedback form, but email and chat also works for now.

    Why this ugly page?
    The application was launch in early September and we haven't had the time to do marketing material. The website is in the works and it will replace this page.

    More info?
    There are installation instructions, source code and other information available on Github.
