Have been given a GoPro Hero HD as a present and I've got a video I'd like to upload to youtube, however the MP4 file it's in is massive and youtube says 100 minutes to upload the video. From what I've researched it takes ages to upload in that format, and people use quicktime pro and other pay software to edit and convert videos, however I'm not wanting to splash out on software, so does anyone know of any that I can use to convert the GoPro format to a more manageable format that I can put in windows movie maker to edit and convert?
