If you have Windows XP it should be there, like I said it's default software. I'm not sure if Vista has it but I'm not sure why it wouldn't. You can import any kind of video file to it, so as long as you get the video on your computer one way or another (digital camera, webcam, etc.) you can import it. Like I said, it sucks, big time, but it gets the job done and if you're broke, it serves the purpose. π
WMM should be under My Computer > Local Disk (C:) > Program Files > Movie Maker > then click on the moviemk.exe file. Then on the left side there will be a menu that will say Capture Video and it'll have your options for getting the video(s) in the program. If it's already on your computer, click "import video" and browse for it. Then the video(s) will appear in the middle of the screen. Then you drag and drop them onto the timeline below and put them in the order you want them. If you want to clip them and edit them, you can click on the clip and drag the end of it to cut off part of it. My first video was one long video, so I had to keep dragging the original video to the timeline and cutting it to just the parts I wanted. It was annoying because it was a 15 minute video and I cut it to like 10-second segments... I'm sure there's an easier way to do it...
As far as the words, go to Tools > Titles and Credits. It'll then ask you what and where you want to put the words, like on its own screen in the timeline (beginning, end, middle, etc.) or if you want the words right on the video. Pick which one you want, type it in, play with colors and fonts, then click done. You can always rearrange them after you do them. The title screens (just the words, not the video with words) can just be dragged wherever. The words that go with the video will appear in its own timeline under the video timeline. You can drag those to wherever you want them to appear on the video. Just make sure you do these last, because if you go back and edit more video, the words that go with it won't follow it to wherever it was displaced to in the timeline.
You can also add an audio track and stuff like that, but I just filmed with music in the background...
These are just the basics, but it'll get you started. Good luck finding the program!
P.S. I'm glad you enjoyed my video so much! I'll have to give you a shout-out in my next one and do a little victory dance just for you! π€Έ
