1: Locate a video
The videos in your library can be identified when a video camera icon appears at the bottom left of the image. There’s also a time stamp in the other corner.
2: Use the transport bar
When the video begins to play you will see a black transport bar appear in the centre of the screen. It’s here that you can access the trim function.
3: Get trimming
Click the settings cog in the transport bar to reveal a drop-down menu. Click on Trim to bring up a new kind of transport bar that will let you edit your clip.
4: Drag it
The new transport bar appears with a yellow surround on the frames. Drag the yellow bars left and right to select a trim region.
5: Hit it
When you’re happy with the trim region selected, hit the Trim button on the right of the bar. Your video will then become the length of the region.
6: Check it
Play your movie and you’ll see that it adheres to the region you selected. Check to make sure it’s the right length and contains all the right bits of action.
7: Go back
You can undo the trim by using the same Settings cog on the transport bar as before. Now you will see a Reset Trim option. Click this to reverse the edit.
8: Time to share
With your clip fully trimmed, you can use the Share option at the bottom of the iPhoto interface to show off the event, place or people in your video.
9: Or just add it
You can also add the trimmed video to a project you are working on. Just pick from the available options and the trimmed version will make its way over.
