Hello Guys,
I'm pretty new at Final Cut Pro X, so bare with me..
How do I render a movie when I'm done making it?
And how do I select the part of the video, that has to be rendered?
Rendering normally happens in the background. Do you by any chance mean "export"? In other words, you want to get the finished sequence out of the application into a video file to share with others perhaps?
If that is what you mean, use the SHARE menu and choose what you want to do from there.
If you have 10.0.6 at least:
Range-based export from Projects
Another feature not seen on the Whats new list is the ability to set a Range in a Project and export only that Range via Share. A much-requested feature thats now available.
