You can use Final Cut Express, Final Cut Studio, Adobe Premiere, Avid Media Composer or if you are running a Virtual PC on a Mac, you can use any program Windows uses.
Yes, there are many other programs. Windows Movie Maker and Final Cut Pro are just a couple.
Get something besides a Mac. :P Just joking. There are some other freeware programs for video editing, but a good paid one is Final Cut Pro.
iMovie on the mac is for editing your unedited movies that you may have filmed on PhotoBooth, or just made on a video camera. You can cut out parts, and add some things and then you have a great movie from the movie you already had.
Movie files should be .m4v files (this is achievable by sharing a movie in iMovie using the iPod feature if you have iMovie from any of the iLife series that Apple makes).
imovie or windows movie maker should be fine for home movies
Sony Vegas, Windows Movie Maker, Apple Imovie (MACS)
There is no software that can play Imovie for Windows. Imovie is meant for Mac users. For Windows users, they can edit movie by using Windows Movie Maker.
A .rcproject file contains details of an editing project from iMovie. It contains pointers to the original videos. To reestablish the connection to the video file the .rcproject should be put into the iMovie Projects folder within the Movies folder. When iMovie is launched the videos from the project will be available for exporting as a playable movie file.
Besides iCarly specials and TV movies already aired, there is no such thing.
There are plenty, Apples Quicktime, VLC, Windows Media Player, RealPlayer, etc. It all depends on how your movies are compressed. If you want to make your own movie then Apples iMovie works.
You can record movies in iMovie and edit them, or do whatever you'd like. When finished, save it on your computer and upload it to Youtube like you would any other movie. The latest versions of iMovie (from '08 onwards) have a link to YouTube in the Share menu and will automatically prepare and upload the movie for you.
There are many horror movies that could be animated besides being made in a live action. Some movie companies do both film options.
