Understanding Alert Messages When Trimming
If you try to perform an edit that isn’t possible, Final Cut Pro displays an alert message.
Insufficient Content for Edit
This message appears when you try to perform a three-point edit (for example, when
dragging from the Browser or Viewer to the Canvas), and the source clip’s media file
doesn’t have enough frames to achieve the requested edit. Click OK to close this dialog.
For example, suppose you set sequence In and Out points to create an edit that is 10
seconds long. Next, you drag a 5-second source clip from the Browser to the Overwrite
section of the Edit Overlay in the Canvas. The “Insufficient content for edit” message
appears because the source clip does not have enough media to fill the 10-second
duration marked in the sequence.
This message indicates that one of the sequence clip items you are trimming no longer
has enough media to continue trimming. This happens even though other clip items in
your selection still have additional media.
For example, suppose you select the Out points of clip items on tracks V1, A1, and A2,
and then roll the edit points to the right. If the clip item on V1 is shorter, a “Media Limit
on V1” message appears. You cannot roll these edit points beyond the media limits of
any of the clip items.

Fine-Tuning Your Edit
This message appears when you try to perform an edit that might inadvertently cause
unselected clip items to overwrite others. This usually happens when you are trying to
perform a ripple edit on one track, and unselected clip items on other tracks cannot
ripple because there are other clip items in the way.
For example, suppose you are rippling a clip item on track V1 to make it 10 seconds
shorter. In a ripple edit, all clip items that occur to the right of the edit point move left
or right by the amount you are trimming. In this case, all clip items should move 10
seconds to the left to fill the gap. However, clip items in A1 and A2 cannot move to the
left by 10 seconds because there are other clip items on those tracks that are in the
way. The “clip collision” message appears.
Clip collision messages are important because they indicate that Final Cut Pro is
making sure that clip items in your sequence aren’t accidentally overwritten. This is
especially important when you are performing ripple edits in a small portion of your
sequence and you can’t see how clip items later in your sequence are being affected.
