Why gaps are great!
Following on from David Lawrence’s Position Tool thread where gaps got quite a bit of bashing, I thought I would stand up for them – at least in one respect – by doing a comparison between FCPX, Media Composer and FCP Legacy.
There’s an editing task that I am sure everyone has to cope with on a very regular basis and that is opening up a space in the timeline so that new material can be inserted, a task that quickly gets quite messy when you have lots of overlapping video and audio clips at the point where you want to open up your space.
Media Composer
In Media Composer – until the arrival of track tool, borrowed directly from FCP – this was always a pretty clunky experience. You would have to do something like inserting filler across all tracks resulting in destructive behaviour – i.e. overlapping clips would get split in two at the edit point – that you would then have to go in and fix.
A different option that I would use but not many othner editors seemed to favour because it was quite fiddly was to use a complicated asymmetric trim, trying to pick up all the right transitions and were possible trim out filler to make the space you needed. And it sure wasn’t quick.
With the advent of the “track tool” it is now possible to select all clips forward from the selection point – which tracks get picked up is determined by the track selectors. It’s an OK solution but you still have to make sure you’ve picked up the right overlapping clips and deselect the ones you don’t want to move, in addition to making sure all your tracks selectors are turned on. Also as this is effectively a Segment Tool function, you can’t use the number pad to enter a specific offset for your move, you have to drag and watch the offset display, which is awkward.
FCP Legacy
As in the new Media Composer, you can use the track tool for this with the added advantage that you can type in an offset rather than having to rely on dragging alone. (Incidentally, I notice a lot of people talking about using the TTT shortcut for selecting all tracks forward – but the much quicker way is to use Shift/T.) There is still the issue of having to select and/or deselect clips that you don’t want included in the move and with a complex timeline that can be genuinely tiresome, especially if you have to scroll vertically to check what’s happening offscreen. Adding to or removing from the selection involves switching back to the arrow tool and using the Cmd key, so quite a lot of extra keystrokes/clicks. It’s OK, it works, but it’s not the most elegant thing in the world.
FCPX
Go to the point where you want to open up the space and Insert Gap (Opt/W). Done. Reliably every time. Unless you have some very anomalous clip connections, everything will move or stay put exactly as you’d expect it to. The default gap is 3 seconds but if you want longer you can select the gap, type Ctrl/D and enter a new duration, or you could trim the gap. For me this is a genuinely elegant and efficient improvement over any other way of solving this non-trivial editing task.
Whatever else I think about FCPX – and I have tons of reservations – I really like the simplicity/sophistication of this one aspect.
At the same time, I believe it is based on a very traditional model of how editing works that goes all the way back to film editing. To accomplish this same task with film you would add an equal amount of spacing/slug in between your shots and into your mag tracks in order to push everything along and keep it all in sync.
For me this is a very solid and intuitive model (based on an actual physical process) that I am happy to see explicitly implemented in an NLE. (As I’ve mentioned before, Media Composer’s use of “filler” is very, very close in conception to FCPX’s use of gaps but without the added power that comes with the latter implementation.) The idea of gaps having a graphical representation and a “physical” reality is for me a fundamental strength not a weakness.
Note that, despite my provocative headline, I am not actually trying to extrapolate from this one feature to make any other claims about the magnetic timeline. I just wanted to point out that here at least it is providing a really fast, accurate and elegant solution to a long-standing editing issue.
