iphone playback jerky on computer

[dominatrix1]

I have just interviewed some people using my iphone as the recording device - However when i uploaded it onto my mac and played it back it was very stuttery which will make it very difficult for me to edit.

However on my iphone it plays back fine .

I have tried opening in i video and it is a little better but still not perfect .

does anyone have any tips ??

Thanks
