Ok I have the video in Filmora
1 second by their clock, marker at every 5 frames
I can count 25 frames in the 1 second

So I am thinking
this was shot by bbc in PAL 25 frames per second
and "transformed" into NTSB at a speed of 30 frames per second for the yanks
the frames seem to be fixed so the other variable is time
the "transformation" played 25 frames in .83 seconds or 1.2x faster
and "shifted" the audio along and rolled up in the vob

when I open the vob the video is new time
and the audio is old time ????

maybe trial and error "snoop a little off here, add a little bit there"
may be the best way to approach
but would still like to figure out how to calculate how far to shift the audio in audacity

thanks for all the input :D :D

the audio files have different and mysterious starts
vob 1 0:32 seconds of silence ok intro
vob 2 2:43 minutes silence
vob 3 5:15 minutes silence
vob 4 7:43 minutes silence
all jobs are 1.07 Gb in size

maybe audacity can only see the "real" audio
and the silence is the time where the magic lip synch took place
"played" 1.2x faster to match the new (NTSB) rate

ok over and out
to find another video editor

I just looked at Daffy and Bugs VHS to DVD
and Filmora said 25 frames per second
NO WAY
homemade VHS copy direct from the antennae in the U S of A 30 years ago
got to be 30 frames per second

30 Years ago from an antenna would have been 29.97.

Isn't this fun?

Filmora edits on 25 fps scale
can output about whatever you want.

I am guessing if the lip/action is at 00:00:25:05:24 on the video,
the audio, as seen in audacity, using 25 fps scale
should be there too.

Current plan:
the speed of the audio seems to have been altered in production?
so that what is in synch at beginning of VOB_01
is out synch at beginning of VOB_2.
Just going to insert blip
by re-synching at the beginning of each VOB.
