If you like FREE…..which will be a bit slower loading when rendering the clips you are editing.
If you are running windows XP, then microsoft movie maker came with that package. It is a simple video editing tool.
If you are running windows 7 I believe it “movie maker” is part of the FREE “Live” download bundle you can download from microsoft.
Personally I use pinnacle, which is the cats meow IMO.
You change the setting so it breaks the video up into 10-20 second segments. Then you drag the few segments you need into the bottom editing area and process. It “Should” save you lots of time because it doesn’t render the entire 37 minutes of video, only the 20-40 seconds you put in your movie.
I think I paid around $60 for that program and its a big time saver versus other software programs free and pay a like.
