Between about 2001 & 2003 I worked on a few semi-professional digital video projects for both web & DVD - editing & compositing plus some DVD authoring. I recently uncovered 3 manuals from that era that I used at the time. These are for: Terran Cleaner 5 - 293 pages, from 2000, for Mac OS 9 DVD Studio Pro 1 - 170 pages, from 2001, for Mac OS 9, with an addendum for version 1.5 - 5 pages, from 2002, for Mac OS 9 & Mac OS X and DVD Studio Pro 2 - 613 pages, from 2003, for Mac OS X These are not litho printed & perfect bound originals though - rather they are black & white laser prints of the PDFs that I downloaded at the time. They are printed double sided on A4 90gsm copier paper, and comb bound with acetate covers on the fronts & backs. Video editing, compositing & DVD authoring was a line of work that I greatly enjoyed and that I would some day like to revisit and ultimately do full time professionally. However, due to reasons I won't bore the reader with, I'm very unlikely to be in a position to devote any time or money to any digital video training or study for maybe a couple of years at least. Now, given how out of date these are, and that I won't be starting to re-enter the world of DV any time soon, which scenario is the correct one: 1. The manuals are worthless - I should remove the bindings & put the them in the paper recycle. or 2. Someone that still uses these bits of software might want to buy the manuals, even if they can still download the PDFs for free, as printing them out & binding them would be time consuming and a pain to do, so I should list them on eBay - I might get 2 or 3 Pounds for each of them. or 3. I should keep them, or at least keep the DVD Studio Pro 2 manual, as even a few years from now some of the information might help me with my studies. The software is out of date but the principles described will still be relevant. I'm sure 99% of people reading this will be thinking - "Why hasn't he binned them already? Does he have OCD & an urge to compulsively horde manuals for prehistoric software that's of no use to anyone?" If you're thinking this then you're probably not too far off the mark, but I thought I'd ask the question just on the off chance that I should hang on to them or put them on eBay. Many thanks.
