I have turned up one article - literally just now - which addresses the whole field:
This piece notes the following:
In the commentary track with Jackson, Fran Walsh and Philippa Boyens, the director and writers discuss the shortened time-frame of the film, suggesting that as little as a few months pass before Frodo and Sam leave Bag End for Rivendell rather than the seventeen years indicated by Tolkien.
They speculate that the timelapse was about a year, meaning sixteen years have been chopped out of the middle. That makes Aragorn older at the time of the B5A, and Frodo younger at the time of the War of the Ring. It means that only sixty-one years pass between the two events, rather than the canonical 77.
Which means that it's (just) possible for a normal mortal human to witness both. That's something close to what I'm doing, but not quite.
