How can you resize video?

How can I resize a video for youtube without having to download loads of megabytes?

• My poor old laptop's overloaded, I think! It's already too slow. I took a video of taiko drumming today - awesome, I have to share it with my friends, but I feel so clueless as to how to do it.

• Answer:

  If you are in windows, then what you can do is the following. Click Start Click Run Type: C:\Program Files\Movie Maker\moviemk.exe This will open windows movie maker. Click File Click New Project Click File Click Import Into Collections Select your movie you want Click Import You'll see it in your main window now, drag it down to what looks like a "time line" on the bottom. Click File Click "Save Movie As" A window will pop up asking what you want to save your movie as, and what type of compression. Pick the first one to make it simple. It shoudl say "My Computer". Enter a name for your video Select "Best Quality for Playback on my computeR" Look in the bottom right hand corner. If it is less than 100 megs, then click Next. If it isn't, click the "radio" button (its round) that says "fit to this size" select the size you want. The lower you go, the worse the movie will be. Click next ,and wait for the movie to convert. It will save the movie to the "My Videos' folder under "My Documents". =D Good luck. You can also edit lenght and stuff, btu that is slightly more advanced!
