interesting article, could any of you A/V heads care to explain some ot the terms for the layman ?
+ diff between online and offline
+ effects like tracking ??
+ what kind of res does Super-16 give
BTW, these guys work with awesome hardware. Best I've dealt with is round robin into twin Sun Starfires
Offline uses low resolution (i.e. heavily compressed) pictures which have low storage overhead and therefore you can fit hours of footage onto a drive. Offline is where creativity, experimentation, long hours, frustration and success/failure happens. Offline pictures shouldn't be broadcast because they'll look cr@p. Offline (Avid) machines are cheaper than online machines.
Online uses full resolution tv pictures and has a heavy requirement for storage. Online droids generally receive either a sequence or edl to plug into their machine, press the "GO" button and feed in the tapes. It is not generally considered to be creative (a horribly misunderstood and misused word), and the job is more suited to left-brain types. Online machines are expensive.
I guess I've been a little disparaging about online, but in the bad old days of linear editing, that's where I cut my teeth. Online is also where a whole bunch of keying, effects and titling is done, and these skills in themselves can be finely honed, which is what separates good online editors from bad. Good online editors also suggest remedies for foobars that bad offline editors hav emade.
Tracking is a technique used by effects bitches to invisibly replace one item in a scene with another, or introduce a new item to appear as if it was always in the scene. Tracking involves selecting an item already in a scene, getting the tracking software to find that set of pixels in every frame, and create a mathematical table which describes where that item is. Using this table, you can "glue" on new things that were never there, or fix things that shouldn' be there.
Trimming is simply adjusting an edit. If a cut happens visually too soon, then make it later. Trimming is the fine tuning of an edit.
Super 16 gives amazing resolution for TV work. Pretty good for low-budget feature work too. With the improvement in film stocks, it is getting more difficult to differentiate between 16 and 35.
