![]() ![]() Picture Type Decision mode: when PTD mode is enabled, the driver automatically determines the input picture coding type either dynamically if lookahead is enabled or statically based on the encoder initial configuration otherwise.Multiple Reference Frames: up to 7 reference frames with support for all reference frame types (Last, Last2, Last3, Golden, Backward, Altref2, Altref).B-frame: support for non-reference, reference and hierarchical B frames.NVENC on Ada GPUs supports for AV1 most of the high level features that it supports for H.264 and HEVC: Video Codec SDK 12.0 introduces support for AV1 main profile encode of 4:2:0 8-bit and 10-bit content for resolution up to 8192 x 8192. *Supported in select Pascal generation GPUs.Support for encoding 8192 × 8192 Content.Ĭapability to encode YUV 4:2:0 8-bit and 10-bit content up to 8192 × 8192 resolution and generate a AV1 bit stream. Support for encoding 10-bit content generate a HEVC bit stream.Ĭapability to encode YUV 4:4:4 sequence and generate a HEVC bit stream.Ĭapability to provide CTB level motion vectors and intra/inter modes. Table 1 summarizes the capabilities of the NVENC hardware exposed through NVENCODE APIs and Table 2 lists the features exposed in Video Codec SDK 12.0.Ĭapability to encode YUV 4:2:0 sequence and generate a H.264-bit stream.Ĭapability to encode YUV 4:4:4 sequence and generate a H.264-bit stream.Ĭapability to provide macro-block level motion vectors and intra/inter modes.Ĭapability to use different reference framesĬapability to encode YUV 4:2:0 sequence and generate a HEVC bit stream. ![]() NVENCODE APIs provide the necessary knobs to utilize the hardware encoding capabilities. These operations are hardware accelerated by a dedicated block on GPU silicon die. It can also be used to generate motion vectors between two frames, which are useful for applications such as depth estimation, frame interpolation, encoding using other codecs not supported by NVENC, or hybrid encoding wherein motion estimation is performed by NVENC and the rest of the encoding is handled elsewhere in the system. This includes motion estimation and mode decision, motion compensation and residual coding, and entropy coding. NVENC can perform end-to-end encoding for H.264, HEVC 8-bit, HEVC 10-bit, AV1 8-bit and AV1 10-bit. ![]()
