How to transfer videos to iphone 4?

Look, I have the newest update on itunes, and i picked a folder with pictures and 2 videos.
I have clicked the ''alow videos'' thing too, but it still don't come.
What am i doing wrong?

What do you mean you picked a folder with two pictures and a video? Itunes will only transfer video that plays in your itunes library and is stored there. I would recommend an app like oplayer for watching videos on your phone, you can use all types of video formats from anywhere on your computer and you don't have to sync them.
