Hardware Encoding with Livestream Studio

Studio version 4.2 introduces hardware encoding as an option for streaming. This moves the video encoding to a dedicated GPU, greatly reducing your CPU usage while streaming.

 

This currently only applies to computers with Intel processors that include Quick Sync Video (which are listed here) or have an NVIDIA GeForce card with Kepler, Maxwell, or Pascal architecture, which includes NVENC.

 

The HD31, HD51 4K, and HD550 4K are the only Livestream-built units that have the required hardware that includes this feature, although many Windows laptops include it as well.

 

We have instructions on how to determine if your computer has an Intel Quick Sync processor or has an NVIDIA card that supports NVENC.

 

To enable hardware encoding in Livestream Studio, click the ‘Settings’ icon in the upper right corner of the interface.

Navigate to the ‘Streaming’ menu.

At the top of the menu, check ‘Hardware Encoding.’ Then click 'Save.'

As an example, here is the processor being used on a Windows 10 computer.

The CPU usage when hardware encoding is turned off—streaming a single bitrate averaging 2128kbps, with 2 media bins, and 1 animated graphics overlay—is nearly 100%. The stream timed out after about 1 minute due to lack of resources.

In comparison, the CPU usage with the same workflow while hardware encoding is turned on was cut in half, down to 48%.

    Will this Feature also become available for AMD GPUs?

    Is there ideal nvidia card(s) to use and will Studio be able to take advantage of multiple video cards?
