2. During encoder initialization, set NV_ENC_CONFIG_HEVC:: enableAlphaLayerEncoding = 1. Clients can also specify the ratio in which the bitrate is to be split between YUV and the auxiliary alpha layer by setting NV_ENC_RC_PARAMS::alphaLayerBitrateRatio. For example, if NV_ENC_RC_PARAMS...
Both the bitrate and the GOP length should be set to the largest possible value allowed by the application, to increase the video quality. Dynamic parameters should not be changed frequently, as that can cause stability issues, because the algorithm does not have time to settle. It is recommen...
Maximum bitrate: Turn on to set a bitrate limit. Bitrate limit: Enter a bitrate limit that is higher than the target bitrate. Maximum: Select to set a maximum instant bitrate of the stream based on your network bandwidth. Maximum: Enter the maximum bitrate. Variable: Select to allow the bi...
