The 4:4:4 and Main10 profiles are choices for high quality encoding - 4:4:4 means no chroma subsampling and Performance, so if you haven't got a good reason to use h.264 (for example you want to encode for a device (older than let's say the GTX 900 series), HEVC is usually better in quality (per bitrate) as well as encoder The codecs currently supported by NVENC are h.264 and HEVC (also known as h.265). The current configuration gets stored in a file called config.json in the program directory. Recording file will be closed and a new one will be opened. If the screen mode changes, the currently (and will pause when that program leaves fullscreen again). Recording will begin immediately, or as soon as a program goes into fullscreen Set up encoding and audio options in the middle, and choose an output directory, name and container format Select the screen you want to capture at the top, You'll be greeted by a configuration dialog.
