Split event before selected clip grayed out

Question

When editing movies, the option "split event before selected clip" is always grayed out...can anyone help???

Answer 1

The reason to split an event is to make the footage easier to find when you start making projects. For example, if you shot a birthday party on the afternoon and a football game at night, they might import into the same Event (based on date). You could select the first clip of football and right-click/Split Event Before Selected Clip. Now you have two Events...a birthday party event and a football event.
This has nothing to do with sharing and projects.
A single project can use clips from many events.
And you can make many projects from the clips in a single event.
The project does not duplicate the footage that is stored in the Event, it just references it.
A project is really a text file that is a recipe for building a movie. The recipe is executed when you "Share" or render your movie.
For example the Project file might say
"Look in Event XYZ and grab frames 1 through 200 from the third clip.
Add an audio track from iTunes, and mute the audio track from the Event.
Add a title that says this or that.
Apply some color correction in these parameters.
Now look at Event QPR and grab the second and third clips, but trim off the last 10 frames."
Etc.
Hope this helps.
If you want to share multiple movies from an Event, you just create multiple projects that reference the event. Choose the frames you need by dragging and dropping. And then share the projects.
No need to get QuickTime Pro involved.
