Typically 16x16. If you want to code an image with a different size, some extra space is coded and cropped out on the decoder.<br /> <br /> 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?<br /> <br /> 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.<br /> <br /> <br /> mod 16x16 sizes:<br /> * 256x144 (16:9)<br /> * 512x288 (16:9)<br /> * 768x432 (16:9)<br /> * 1024x576
