You cannot selectively trim file-based clips like the GH4’s upon ingest into FCPX but there are two ways you can get around this:
Option 1. Import the entire file in FCPX, but without copying the media to the Library (via Preferences).
This way you can work with the file in FCPX without making another copy of the large file.
Option 2. Trim the file before importing it.
Open the file with QT player.
Choose Edit > Trim. The trimming bar appears.
Drag the yellow trimming bar handles to the left and right to select the portion you want to use.
Then click Trim and choose File > Export to export the selection to a standalone movie.
When the export is done close QT player and when asked do not save the changes. This will leave your original file intact.
Now you can import import just the selection in FCPX.
