Image Size
The first step of encoder setup is to adjust the image size. The NVS-25 allows you to
downscale the output image and set the SD aspect ratio at the input. The Scale Down
function, as the name suggests, allows the user to shrink the image size. The table
below shows all possible downscaled resolutions on NVS-25.

H.264 Encode
The H.264 standard can be viewed as a "family of standards" composed of different
profiles. A specific encoder encodes at least one, but not necessarily all profiles. The
NVS-25 offers the user three profiles: Main Profile 3.0, Main Profile 3.1 and High Profile
4.0.
