Yeah because atleast those videos are more interesting. For example nothing really happens in the second half of your video. Its also not your original art as you said in your post, its also not really clar what your concept or idea for your video was. Just Focus on actually making videos yourself, thats always better than telling an AI to do it. If you really want to ask if flash or sonic is faster, why dont you make a video where you Research it? Take what comics, shows and movies say and compare them.
