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. 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. Enforce Streaming Service Encoder Settings: Leave this checked, this will ensure that if you enter a wrong value by mistake it gets corrected.Encoder: Select NVIDIA NVENC H.264 (new).This gives you access to all the settings. You may want to consider streaming at a lower bitrate and resolution to lower the bandwidth required to see your channel. This is important if your viewers are on mobile phones or their internet speed is not as fast. Twitch only offers guaranteed transcoding to Partners non-partners may receive transcoding, but it is not guaranteed. Transcoding allows a viewer to view your video on a different resolution, thus requiring a lower bandwidth. Note for New and Upcoming Streamers to Twitch. For example, for Fortnite, many streamers decide to stream at 1600x900 60 FPS. If you reduce the resolution, you reduce the data being encoded, and the resulting viewer quality is higher. High motion content cannot be compressed as much, and can suffer from more artifacting (encoding errors) that make your stream look “blocky”. Racing games, some Battle Royale games, etc.) we highly recommend reducing your resolution. If you are going to stream high motion scenes (i.e.

* Important Note for High Motion Content. Most streaming sites have recommendations ( Twitch, Youtube, Facebook Gaming) on what to use.

Then, we will determine the resolution and FPS that we can use for such bitrate. We want to use around 75% of your upload speed, as the game and other programs such as Discord will also fight for bandwidth. While the same applies for framerate, a viewer can really notice a drop in FPS but not so much in resolution, so we will always try to stream at 60 FPS.įirst, run a speed test to determine your upload speed (e.g. The smaller the size of the image, the less we must compress it and the more quality it keeps. Encoding is all about compressing images.
