How to put movies on my iPhone?

I recently got an iPhone 4S. I know how to download music but I'm stuck on downloading movies. Can you help?

If you want to transfer movies from your computer, just use itunes. Transfer the video file onto it and then sync. Also, itunes supports only several video formats so you might have to convert your video with other software.

  • Will my iPhone get heavier if i put more things into it like movies and music? I have a 16GB iPhone 4S and I was wondering if my iPhone will get heavier with more media in it? For example, if I put 3 HD movies, 110 songs, 3 audio books, and podcasts in it, will it gain like 1/2 oz? I mean, with al that media, it has to, right?
  • Why won't my movies sync into my my iphone? I have the Iphone 3GS and I can clearly see the movies in the Itunes movie library but it won't sync! Any ideas? Its 720p HD also.
  • Where can I download movies to put on my iPhone / iPad? What reliable websites are there for downloading movies to put on my iPad? ITunes is so expensive so I'm trying to find other competitive websites. I'm not looking for movies fo free - but a trial would be good. Much appreciated!
  • Is there an iPhone app to stream movies from my computer to my iPhone via a network? The ability to stream video files that are on my computer exists on other devices I own (for example I can watch video files from my computer on my Xbox 360 without having to move them since my computer and Xbox are on the same lan network).So I'm just wondering if there's a way to watch my video files on my iPhone while being connected to my Wi-Fi (the same Wi-Fi my PC is connected to). I hope I explained this in a way that makes sense.
