To be precisely correct it's not even a second I have to stretch this file more
but .155 of a second. Sounds like a small thing, however, for the synchronizing
audio and video it's 5 frames of NTSC video and it will be noticeable. So
really the best thing for me is just to make audio slower to match it.

That's more like 1/6 second to my mind, but it's close. Rather than
slowing down the audio, you can remove little chunks here and there between
words. If you do it evenly and cleanly, it can match up nicely.

It's much easier in the video world than it was with film. With 35mm film
you can only remove 1/4 frame since you have to line the perfs up. This is
1/96 second, which can sometimes be an awful lot in a musical piece although
it is reasonable enough for cutting dialogue. 16mm was even worse since you
had to take out one frame at a time from the sound mag since there was only
one set of perfs per frame.
