ok, the video isnt so good so here are some tips when using movie maker to make it from 4/10 to something like 6/10.
1) the text, you
can change the headline's effect, cause no body wants to see the normal blue background and white text right? try changing the background to black, or any color that seem's nice, change the color of the text (ah but doesnt matter so much realy, better keap it white), and most important, the font, movie maker has lots of fonts beside's the ugly normal one's, try looking for a font that is speacial and not to crapy...
change the appeariance too, better make it come like credits, or written in big, play with it.
2) Effects: as you allready know movie maker has lots of effects, but trust me, lots of them are just to lame to be in a video (pixelrate, hue switch, ETC...) but you can put speed in, too fast? dont take it off, put a slow motion. here is why, the video is running on 100%, speed effect double's it, than we have 200% some time's its to fast (on madmans let's say) so we put a slow motion, cause a slow motion is only lowering it by 50%, so we have now 150%, its pretty fine. other effects better not mess with them they just make the video worse.
3) Transition: nothing to say realy, just dont use the sharp one's, like Zig-Zag oppening, windmill openning, chese table. try to use more smooth one's it will sure make it nicer like: fade... and anything ele's that isnt sharp -_-
4) dont repeat stuff to much, like sharp transition's or effects, it will just make the view'ers tierd...
5) good luck make a re-re-edit
