If you’re using Windows Movie Maker, there is
the possibility that you mistakenly saved your
video as an MSWMM file with "Save Project",
instead of a WMV or AVI file with "Save Movie
File" (Windows XP) or "Publish Movie" (Vista).
There is a monster of a difference between the
1st example and the rest: the 1st is really just
a "work-in-progress" saved within Movie Maker
and is not even a "true" video. The others save
your file into what you need to properly upload
it to YouTube.
The most efficient way to save your video such
that you can upload it is:
1 -- click the blue "Tasks" icon.....(you'll get the "Movie Tasks" menu)
2 -- click "Finish Movie", the 3rd option.....(it will expand to 5 choices)
3 -- click "Save to my Computer".....(the "Save Movie" wizard appears)
4 -- enter the name of your movie.....(it is best to stay in "My Videos")
5 -- click "Next" at the bottom.....(you'll get the "Movie Setting" page)
6 -- click "Best quality for playback".....(it's usually the default setting)
7 -- click "Next" at the bottom.....(you will get the "Completing" page)
8 -- click "Finish" at the bottom.....(the saving may take quite a while)
9 -- click the blue "Tasks" icon again.....(you'll get the "Movie Tasks")
A -- click "Finish Movie" again, the 3rd option.....(you'll get 5 choices)
B -- this time, click "Send to the Web".....(I'm sure you know the rest)
YouTube recommends the video format be
MPEG4 at 640x480 recorded together with
sound in MP3 audio, all at a rate of greater
than 24 frames per second. Other files that
are accepted include AVI, MPG, MOV and
WMV (which is Windows Movie Maker).
