Right on Grinner, preach it! And to put it in car terms, what’s the difference between a Maybach and a Kia? They both get you across town in heavy traffic about the same speed. The difference is all in the details, and each job is a custom job.
I had a boss in the eighties that threw around a rule-of-thumb figure of a grand per finished minute, with general success, but over the years I’ve come to believe that the reason it was a relatively close estimate *for us* was that the underlying criteria it was based on were EXCEPTIONALLY NARROW. I.e. it would not apply equally to anybody else’s work product but our own, and that, only within strict limitations of time, manpower, certain equipment used and an average of one day’s editing figured in.
That was in the days where everybody shot with umatic or betaSP, mastered to one-inch in an A-B roll linear edit suite, with limited graphics and special effects, and not a lot of added-value things like foley or audio sweetening, just Chyron VP2 CG text and DeWolfe needle-drop music, (using real needles and turntables!) done and out to VHS dubs…
Today, you have so much more power available at a fraction of the relative cost of those eighties rigs, it’s not even funny. But the fact of NLE usage is, the extra power and flexibility can make you work faster, but just as often, you wind up not much faster than a linear edit, because you spend the extra available time trying a lot of variations and alternatives you’d never have time to entertain under deadlines in the bad old linear tape days. Overall then, you’re not much faster, but objectively better. And that’s worth charging for.
And that’s why if you say a thousand-per-finished minute today, or NAy hard figure of that sort, unless you add all the tiny legal double-talk at the bottom of the screen that says exactly what you do and don’t do for that amount, your kilobuck-minute figure will wind up being over or under the real amount.
Neither of thsoe is good, you are either leaving money on the table under-charging, or possibly pricing yourself out of business. A hard number rule like you propose ignores a lot of the key factors in cost and commoditizes something that should not, cannot accurately be commoditized, IMO.
When the minutes don’t add up as you predicted, because every job has unique nuances, the client will start to think your’e a liar or incompetent.
Rules of thumb like this become a Chinese Finger Puzzle; don’t do it.
