Current video codecs encode frames using particular block sizes, so the coded area must be an integer multiple of some common size. Typically 16x16. If you want to code an image with a different size, some extra space is coded and cropped out on the decoder.

The performance impact of this extra coding is pretty negligible, but in the absence of other reasons for choosing a particular frame size, why not choose one which is a multiple of 16x16?

Most video formats can also support non-square pixels but non-square pixels require client-side re-sampling which can be expected to be low-quality.
