Question...!

[Chibi Mystic Gohan]

You know how when you save something in Windows Movie Maker, it saves the video at that reeeeeeeeeally small size, so when you play it in some media player, it resizes it and makes the quality look pretty bad?
How do you change the size that it saves as?

[lost in thought]

Uh... don't save your final work in Windows Movie Maker?

[Chibi Mystic Gohan]

...<_< What do I save it in then?

[lost in thought]

Uh, I think you can find out that, and more by using the help guides at the AMV.org site. However, I think Mike pointed out exporting your timelime to HuffyUV or some shit, and then saving it in a lossless something or other with DivX or some shit.
Sorry, I can't be much more help than that... since all I know is saving with Windows Media Player produces horrible videos.
