  1. I just wonder, as I know that FFmpegX defaults to multiples of 16.

    I mean, to really accurately reproduce 16:9, 320*180 is much more precise than 320*176 or 320*192.

    Is there some reason we should't use dimensions that are not multiples of 16 for h.264?

    In my limited experience, it doesn't seem to make much difference until you try to scale it, then you tend to get scan-lines. The original MPEG4 standard called for 16x16 blocks, so it is most compatible as well.

    To prevent stretching of your video, just add padding so that the resolution is 320x192, but the image itself is 320x180. Add 6 pixels to top and bottom.
