I took some videos on my Handycam and I removed the dvd and put it on a laptop and extracted the videos. But when I go to edit them on Windows Movie Maker, the video is not showing how it needs to. On VLC Media Player, it says 24 seconds but it's acting weird because it's actually much longer. As the videos have been taken from a Handycam, they have been taken at different times but are a part of the same video. How do I rectify this?
