Windows Movie Maker -Outputing Videos

So I have finished making my video,saved it and then i tried uploading it to YOUTUBE But it says it doesn’t support the video, then I Read up on what kind of video formats youtube Takes and it takes H.264, MPEG-2 or MPEG-4 codecs and My video is V.7 WMV or something and im not sure how to change the format or Codec or Whatever and when i did try to change it and it told me ...

“The conversion of your video file has faileD. This can be caused by a not supported combination of parameters or non supported codecs."

Im not sure what to do or how to change Codecs on Windows Movie maker/put in parameters, and im not too good with computers.Help would be much appreciated. thanks

First thing to check before I do anything else (and to rule this out): when you saved your file, did you click file, save project as in movie maker? If so, that saves the project (aka the steps to make the movie, the list of source files, the effects and transitions, etc...) - it does not create the final movie! To create the movie, you have to click on save to my computer at the bottom left (under the “3. finish movie”).

If you did that correctly, but youtube won’t convert, what version of Windows (including service pack) are you using? Because I think Movie Maker 1 (the version in Windows Millenium Edition) used to output in Windows Media Video 7. Windows XP has Movie Maker 2. I’m not sure what Windows XP without any service pack outputs as (possibly Windows Media Video 7 or 8), but I’m pretty sure Windows XP with service pack 2 or 3 will output in Windows Media Video 9.

If you’re using one of the older versions, I think updating your version of Windows Media Player to 9 will do the trick.

If that still doesn’t work, use Windows Media Encoder 9 (download is on the same page) and re-encode your video to Windows Media Video 9. If you use Windows Media Encoder, it’s probably best you set your own settings rather than using the default profiles.
I wrote some steps for using WME here (see post #2). In your case, the steps diverge where you create a profile. Use quality VBR, 85% quality or higher, use same resolution as input, same frame rate as input).

If you’re still stuck at this stage, report back on what format your source files were in, and what format the file(s) created by Movie Maker are in. Use the tools listed on this page if necessary http://www.moviecodec.com/topics/61931p1.html
