When I select a clip in Final Cut Pro, and press ctrld to edit the duration, I can enter 100 then enter and it will make the clip 1:00 second long. However if I try to do 30, it still rounds it up to 1:00 second long. Why won't it let me make a clip appear for a fraction of a second?

:30 is 1s at 30fps, so FCPX rounds it to 1s. For half a second on a 30fps project, enter :15.
