This is an App help you cut the best moment from your video.

It occurs to me when I came back from Disneyland, one of my friend was laughing out loud during an event. She is rarely laugh. Try to get that moment is quite hard on iOS and even in Desktop computer. So since I am a programmer I start to figure how to quickly find a clip in a long video.

Finally I came up with this app.

With rotate and flip you can adjust the clip's rotation, and using the scale you can set the frame preview to a more specific level.

Hope it's useful for you!
