![]() ![]() HEVC: Set to main if you are going to capture in HDR, set to main10.You can increase these to 100,000 and 200,000 (respectively) for higher quality. Bitrate and Max Bitrate (VBR): 40,000 Bitrate 60,000 Max bitrate.CQ Level (CQ): 15 (you can decrease the number to get higher quality).Rate Control: We recommend CQP, although VBR will also produce good results.Audio Track: Leave it at 1 for default you can add more audio tracks if you are using more sources.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. HEVC: Set to main if you are going to stream in HDR, verify the profile is set to main10.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. Multipass Mode: Set to Two Passes (Quarter Resolution).Preset: Select P6: Slower (Better Quality).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. ![]() Bitrate: Enter the bitrate appropriate for your Upload Speed, as we discussed in the previous section.This determines the rate at which frames are going to be encoded. ![]()
