Yeah… what you’re saying is a common one: Premiere Pro seems to ride the best balance between convention and new technology. Not quite sure how us other editors can genuinely add to your discussion. It seems you’ve thoroughly investigated and made a well balanced opinion.
I began my career on FCP7 and often wished for the death of Avid. Then I switched to Media Composer and funny enough, I prefer it now (probably due to the disproportionately high amount of training I received on it, versus the competition). However, I’m also editing a series on Premiere Pro too: great software. Their trim mode is so damn Avid-like now. As an Avid user… I feel very comfortable on the new CC 2014 version.
That being said, now that I’ve been using it frequently I am realizing that once the project size gets fairly large, the speed advantages of the engine start to dissipate (to be fair, we’re editing native AVCHD and H264… unheard of for Media Composer) … but… I guess the point I’m trying to make is that many of the speed advantages in all the NLEs starts to fade a bit into the background as the daily grind of editing just takes its course, until it doesn’t really become a topic of contention anymore.
