Once in a blue moon one stumbles across a piece of software that is so good and so intuitive you have to make mention of it. So here is a plug!
A couple of days ago I ran across
Arctic Whiteness' Final Cut Library Manager.
If you don't use Final Cut X - read no further.
If you do - get this software - it makes managing Libraries a total doddle.
One of the big things in FCP X 10.1 was the agglomeration of all elements of a project into a single all-encompassing Library file. Events & Projects live within this Library.
All well and good but it makes archiving a bit of a task since one potentially can archive all kinds of space-consuming material such as renders, proxies, optimized media, thumbnails & waveforms. All of which can be easily re-created if needed.
Library Manager searches your complete drive system for FCP Libraries, indicates the amount of space within each Library that those FCP created files consume and with a couple of clicks, allows you to eliminate them. It even warns you if it cannot find the original media.
There are several other neat extras - such as allowing you to open just a single Library of your choosing at a time.
The interface is about as clean, intuitive and uncluttered as an app could and should be. Really worth the $10-12 to purchase. IMO
BTW Lightroom users who also use an iPad, MBP trackpad or wireless trackpad should check out
The Touch which looks pretty cool too. They also have a good selection of LR plugins...
