iMore

Hi,
I'm editing a music video on my iPhone 5, using iMovie. I've been very careful to painstakingly sync any hand clapping and to the beats in the music, as well as the even more delicate lip syncing to the song's lyrics. When I play the video in the timeline, it's absolutely perfect. Then I save it to the camera roll and transfer it to my computer and all of a sudden the syncing is out. Not hugely, and not in all the clips just a few at the end.
It's HD 1080p, just over 500mb, and I haven't changed it from .mov. I've opened it with VLC on two laptops and it's been out, as well on my TV. It's very frustrating and I'd really appreciate any insight.
Cheers.
