Programs to put videos together?

Not sure

Windows Movie Maker is an option.

Windows Movie Maker (comes with windows computers. for beginners. it isn't going to attract any attention, but it's just all the basic stuff)
iMovie (comes with a Mac computer. easy to use. pretty good for effects and quality of the music.)
Sony Vegas (extremely good. has a bunch of different things for musicians. change the pitch and everything audio-wise. effects are good. quality is good. it's hard at first but you get the hang of it.)
i highly suggest Sony Vegas. all of them are good, but try to get 9, 10, or 11. $100 for Platinum version, but I got all of mine on ebay for about $20 a piece

Good Luck!

Windows movie maker.

If you need to make a movie:
Windows Movie Maker
Picasso
iMovie (Mac)
If you need a slideshow any of the following will work:
Windows Movie Maker
Photo Story
Picasso
iMovie (Mac)

If money isn't an option, i would go with adobe Premiere Pro creative suits. If it is them there is a software that is free that was used to edit the movie "The King's Speech" I'll add the link to download it in the sources. Now this is complicated software but it can do allot and once you watch a few tutorials it is easy to use. And both sould work on mac or pc

There's a lot of programs you can use to put video clips together to make a movie. Some automatically come with your computer/laptop, like Windows Movie Maker. (although note that the versions are different depending on what Windows version you have) This program is simple and easy to use, but it's not the best. iMovie is a step up, and comes with the Mac, but you can download it too. There's also Sony Vegas Premiere or Pro, (more advanced program) Adobe Premiere Elements, (I have this program and it's absolutely amazing) and finally, Final Cut Pro, a proffesional editing program. It's what filmers use to make movies and pretty expensive. My advice to you is based on what videos you are going to upload, you should think about what effects you would want to add to it, how complex you want your videos to be, and judge it from there what program suits you best. Remember, don't choose one that you think might be too hard for you to use, practice with the one you get, and then once your better at editing, move it up one level. I hope this helped and good luck posting!

windows movie maker, it isn't the only one, but it is only of the best ones I have used by far, and I believe it's free. if you Google it.

Windows Movie Maker

and

Windows Movie Maker Live (The best one)

Both are free

there are many different programs for video editing, just google it and you'll get a thousand and one reasults. Personaly I prefer using adobe premeir pro, it has an excellent visual display and you can add effects.
It has a 30 day free trial but just do what everyone does and look up a serial this>>(http://www.youserials.com/)<< is a good site for that

Here are some free options, just click on a program to see if it fits your needs...
