Final Cut editors tend to be much more advanced and adaptable in these situations. Most Avid editors can’t think outside the box (ha ha ha….sorry). If I were you, I’d say something like “Oh, you don’t know how to do that?” act surprised at their lack of abilities. Leave it at that.
We still have Avids in house, and have been converting our clients to Final Cut. They say “Oh, you’re using Final Cut?” To which we reply “Yeah, it’s really a much more versatile and effective system than our Avids. I’d rather edit with Final Cut any day.” We switched 4 bays over when Avid offered to upgrade our Media Composer 7.1s to Meredian for $30K a piece. 30,000 dollars a piece!!!!! See ya later suckers.
I do sometimes think Apple markets FCP more like a prosumer app than a industrial pro app. And some of the features and effects are really better for wedding videos than pro grade work.
