Make sure the hard drive you select has enough space! Recording Path: This is the directory where the videos will be saved.If you uncheck the Look-ahead option, reduce this to 2 B-Frames. This is not recommended, as NVENC is already very efficient and the little gain you can get from using a second card is lost by having to copy the frame to the second GPU. If you have 2 GPUs in your system, you can select which one is used to encode. This enables the Rate Distortion Optimization in the encoder, which greatly optimizes the way you use bitrate, improving image quality on movement. This feature is CUDA accelerated toggle this off if your GPU utilization is high to ensure a smooth stream. Look-ahead enables the best of both worlds. B-frames are great because they increase image quality, but they consume a lot of your available bitrate, so they reduce quality on high motion content. This allows the encoder to dynamically select the number of B-Frames, between 0 and the number of B-Frames you specify.
It doesn’t impact performance and gives access to a set of features that are key to streaming, so this should always be set to High. Profile determines a group of settings in the H.264 Codec. You can change this to Max Quality to enable 2-pass encoding this will provide you a minor quality increase but may cause problems in limited situations in maxed out GPUs. Streaming platforms may limit what you can select here, and most require a setting of 2. Keep in mind that some platforms have a maximum bitrate (i.e.
