A large number of presets -There are currently nine presets, but they often have an inadequate quality or performance tradeoff.Because NVENCODE API guarantees binary backward compatibility, it has been difficult to reorganize the presets. These presets evolved over the years, with multiple hardware generations and encoder features getting introduced in each generation. LOW_LATENCY_HQ (Low latency high quality).LOW_LATENCY_HP (Low latency high performance).The presets exposed in the NVENCODE API currently are as follows: The NVIDIA NVENC presets design in Video Codec SDK 9.1 and earlier evolved based on various NVENC use cases, which have emerged over time. All NVIDIA GPUs starting with the Kepler generation support fully accelerated hardware video encoding, and all GPUs starting with the Fermi generation support fully accelerated hardware video decoding through the NVIDIA Video Codec SDK.
