How Do I Put Video On Windows Movie Maker?
Okay. So you know Windows Movie Maker. how you click import
and you pick which video clip to put in. That, or you go to your documents and you drag a video into your collections..well mine doesn’t work that way. well anyways something wrong with mine now that i have to drag and drop mine in, same way anyways, but that’s not the point. the point is, what am i doing wrong that my videos from my digital camera wont go into windows movie maker. i just don’t know how because i recently tried to import a video again and it just doesn’t work. what am i doing wrong? when it comes to technology im pretty much blind. My camera is a nixon coolpix 5200 so maybe that’s it? maybe i don’t have an “updated” movies maker? i don’t know. so can anyone help me? please? i will appreciate ever so much. (:
First, i’d like to know the format of ur video, u know, Windows Movie Maker only supports several file formats like AVI, WMV, MPEG-1 and ASF file formats, if unfortunately, ur video files do not fall into the categories, im afraid, u have to convert them to the above mentioned file formats, this one may help u, good luck
