My review for this test creation: Although I used a widescreen start-image (16:9, 1024x576) as input this time, I still got an undesired 1280x768p (16:10) aspect MP4 video as output. I haven't figured out the cause for this issue yet. I'm sure there is some special setting there or combination of elements to force the video models to render an output video in standard HD 1280x720p resolution, as I unconsciously managed to do so prior when I created my first Daenarys Targaryen HD 720p animation MP4 video some while ago, for comparison:
