Hey Tim,
Adding to Jim’s suggestions, you need to have the end in mind.
As in what technology will you be using to play this back with, and how are the videos distributed.
As such it is not rocket science, but there can be some surprises waiting for you in terms of syncing the monitors, and local isolated playback from individual boxes, versus all coming out of one point of distribution (server).
Personally, I’m not sure that I would use FCPX for this kind of job. Not least as Apple at the best of times makes it difficult to lock tracks. Where as on other more old fashioned “linear” NLE’s you can have 30 vertical videos on 30 video tracks on a 30-split screen (or 10 split screen), with nested tracks running in each of those. You will need a fairly high spec computer with a serious hard-disc with speed and space to make that happen.
If the 10 screens are not connected, you could also just have 10 timelines, with 3 nested tracks in each. But you still need to find out what the playout format is?
Going big, and potentially a hazard on a smaller system, will allow you to time forexample interviews, and when they appear on different screens across the whole installation. Are there specific points in the installation where the audio is changing from low to high volume.
Motions graphics is another one where you can have themes travelling across the screens.
Again, it really depends on having the end in mind.
For a project that size is there a director and/or producer attached?
Or are you on your own?
3 vertical timelines simultaniously, I’m sure that FCPX can handle that. But these kind of of projects tends to grow. And being able to lock your videos and tracks in place, and not allow FCPX to move your footage around, will save you time. Yes, I know that there is work-arounds on FCPX, but incoparison to the obvious where you drop onto a specific track in the timeline, and can quickly apply the right frame to it, is a must for speed of editing, delivery and revisions.
Start with the end in mind, and work your way back from there, and it will all fall into place for you.
Sounds exciting – go have fun!
