Matthew Berman explains how a dedicated NVIDIA video encoder can take encoding work off the CPU, and highlights Broadcast effects for audio and video. The video is an NVIDIA partnership; it presents features rather than a measured comparison of streaming performance.
- 1Streaming workloadBerman describes the CPU workload of gaming and encoding simultaneously and notes that some streamers use two PCs.
- 2A hardware encoderHe says NVIDIA's dedicated encoder handles video encoding so the CPU has more capacity for other work.
- 3Broadcast effectsHe highlights audio cleanup, virtual backgrounds, eye contact and low-light video noise removal.
ポイント
- Hardware video encoding can reduce CPU encoding workload while a game is being streamed.
- NVIDIA Broadcast offers effects including noise and echo removal, virtual backgrounds, eye contact and video noise removal.
- Performance and feature availability depend on the hardware and configuration; the video does not benchmark them.

Encoding while gaming
Berman describes the load of streaming a game and the role of dedicated hardware encoding. He contrasts it with CPU encoding and dual-PC setups.
Streaming a game and a camera feed at the same time can place a heavy workload on a computer. I describe CPU encoding with x264 and the dual-PC setups some streamers use. NVIDIA's dedicated hardware video encoder can handle encoding separately, freeing CPU capacity for other tasks; the effect on actual gameplay depends on the system and settings.
NVIDIA Broadcast effects
He lists audio and video effects available in NVIDIA Broadcast. The video is marked as an NVIDIA partnership.
NVIDIA Broadcast also offers AI-powered effects, including noise and acoustic echo removal, virtual backgrounds, eye contact and video noise removal for low-light footage. I suggest checking NVIDIA's AI Decoded article for details. This video is an NVIDIA partnership, as disclosed in its description.
