We have recorded 40 odd tracks of live performances on several Digital
Video cameras and the audio parts on a Fostex 24 track digital
recorder bridged to a Mackie. These tracks have been saved to disk via
a Mackie setup as .wav files. I am having problems syncronising them
after importing them into Logic Pro 6.4.1. I can not find a timestamp
utility and am at a loss what to do. I want to import the audio first
into FInal Cut Pro (after mixing it in Logic Pro) and then set the
time code of the Video tracks to be syncronised with the Audio to be
able to overlay and edit from the various Cameras and also from Video
footage of the same show recorded at different venues to eventually
make a DVD. But since the Audio needs to be set first and timecode
linked to it I'm stuck if I can't get the audio channels syncronized
first.
Can anybody help me?

I'm not aware of such a utility, though it seems like it would be
reasonable for someone to write a utility that puts the Broadcast Wave
time stamped header on a file, with the time that you choose. However,
even if you had such a utility, what would you do with it? How would
you know what time to put on the beginning of each of the files? If
they were made on different, unsynchronized recorders, they were
almost certainly all started at different times and were most likely
running at different speeds (though this isn't a really big problem
when using digital recorders all around since crystal clocks are
pretty accurate). No, there's no east way out of this hole you've dug
for yourself.

The way to do this is to manually (with your eyes and ears) "spot" the
audio file to the video, and if necessary with long segments (because
the audio and video recorders weren't synchronized), edit the video to
coincide with the audio.

The real answer is to do it right, with all the recorders synchronized
to the same time code source.

Thanks Mike,
The problem is that I have 40odd individual .wav files (one for each
instrument in the orchestra or something like that) that are neatly
sorted out all in a folder but the ones that were recorded on the
Mackie originally are slightly out of time with those coming from the
Fostex. We don't own a Mackie only the Fostex so we had the files
copied to harddrive in a studio. Unfortunately they don't use Logic Pro
and I have not found anyone yet. The two machines were connected by
word clock and syncronized when the concerts ware recorded so the
tracks should be OK.
I am not concerned about getting the video in as we have a Sony DVCAM
capable of timestamping but my problem is simply that I can't make the
jolly audio files start exactly simultaneously and I'm sure there must
be a very simple way of placing them underneath each other and shuffle
them around (by ear) so they start at the same time like the musicians
did in tghe performance, which is what in my simply understanding of
the meaning of the word I call "syncronize". Since it was parformed
together it's just the start that needs fixing, the rest will
automatically be perfectly together.
Once I have to audio loaded in, the Video can be played in with the
timecode that than sets it for both audio and video and locked in once
the have both been placed into Final Cut Pro. At least that's my
theory..... but who am I, just a stupid musician........
Thanks for your help

Seems easy enough to do.

The tracks (files) from the Mackie should all start at the same time as
each other, and play back in sync....same with all the tracks from the
Fostex.

So what you need to do is:

Grab all the files recorded on the Mackie, and line them up so they
start at the same time. Group those tracks together.

Do the same with the files from the Fostex. Group the Fostex files
together.

Listen to the Mackie group, and find an easily identifiable place (say,
the first downbeat), and trim the beginning of that group to that exact
place.

Do the same with the Fostex group.

Now drag both groups so they both start at the same place.

Listen....

if everything's good...

open up the beginning of the files to expose as much of the time before
the downbeat as you need.

It's up to you to deduce how to get the video sound into the session (if
you even need it).
