Thank you for your interest in CasparCG Server, a professional software used to play out and record professional graphics, audio and video to multiple outputs. CasparCG Server has been in 24/7 broadcast production since 2006.

The CasparCG Server works on Windows and Linux.

• A graphics card (GPU) capable of OpenGL 4.5 is required.
• An Nvidia GPU is recommended, but other GPU's will likely work fine.
• Intel and AMD CPU's have been tested and are known to work
• PCIE bandwidth is important between your GPU and CPU, as well as Decklink and CPU. Avoid chipset lanes when possible.

• Only Windows 10 is supported

• Ubuntu 22.04 or 24.04 are recommended
• Other distributions and releases will work but have not been tested
