Nvidia Share

Nvidia Share (formerly Nvidia ShadowPlay) is a hardware-accelerated screen recording utility for Windows PCs using GeForce GPUs, made by Nvidia Corp as part of its GeForce Experience software. It can be configured to record continuously a time behind, allowing the user to save the video retroactively. Share is supported for any Nvidia GTX 600 series card or higher.[1]

Technical details

Share can use two capture methods: Frame Buffer Capture (NVFBC) and Inband Frame Readback (NVIFR). NVFBC is used in full screen mode. NVIFR is used in windowed mode only because it has a higher performance impact.

Once Share captures a frame, it encodes it using a dedicated GPU hardware accelerated H.264 video encoder that records up to 4K resolution at 130 Mbit/s with minimal performance impact to the rest of the system. [2] The bitrate can be set manually and ranges available depend on user screen resolution.

Release

Share was set to release at the same time as the Nvidia Shield (June 2013) but was delayed and was pushed to being released during the summer of 2013 but was postponed again. On September 20, an Nvidia forum representative posted a thread to the GeForce forums, stating that the product was being delayed due to a problem with the video formats. It was released in a public beta on October 28, 2013 in the 331.65 driver. Before version 3.x of GeForce Experience, "Share" was known as "ShadowPlay."
