For those of you who have uploaded videos onto youtube using windows movie maker, how do you do it? i've been trying for days and i still cant get them to upload. first i found out the file was too big, so i looked for a way to make them smaller. then i was told to use windows movie maker and save them as a "compressed file". well i found WMM on my pc and saved them, but idk how to save them as a compressed file. well i saved them by clicking "save as" and tried uploading them that way onto youtube, but then after the video processed, it said it was an invalid format. so now im really close but i need someone to show me STEP-BY-STEP on how to upload videos onto youtube using WMM.
