Iphone Video Uploading

[R1-Jay]

Ive done this in the past but cant remember now how it was done

i have a video i have made of my last scuba dive and i want to get it from laptop to iphone.

ive tried itunes and added the file, but nothing happens or appears

sure i used a piece of software before that could copy the file and change the format so it automatically worked on the iphone
