Clock drift is not usually an issue IF you substitute audio tracks and
are only
worried about lip sync.
It IS an issue if you need to mix the tracks and phase errors become
significant.


That's true. Don't do that.


After a microphone comparison, pair of omnis and pair of cardioids I tried
using the omni pair for ambience with a slight delay added. What I didn't
try was compensating for the drift via a stretch of one pair of audio files
and it was in the age of the P2-300 so it was not an attractive chore to
venture into. But without fixing the drift the maximum duration of stable
perspective was some three minutes with one mic pair recorded on one DAT and
the other on another, after about that long time the (fake) room size
perception changed to another size. Hmmm ... wondering whether those tapes
still will play back ....
