Hi Sarah and Barry,
First, Barry's instructions about using the "cat" command in terminal
to concatenate files are quite accurate, but they won't solve Sarah's
problem about how to join .mov files and end up with a playable
result, and this has to do with the structure of these files. Such a
file joining program has to both put the data in the individual files
together, and update the header information so that it reflects the
new total length. Further, there can be potential incompatibilities
between the different files being used -- an easy example would be if
you were joining constant bit rate audio mp3 files, where one of the
files was encoded at a different bit rate. If all the files are
constant bit rate and encoded at the same rate, it's relatively easy
to just concatenate the individual files (with a "cat" command), and
then to update the file header information to reflect a new total
time. However, once you include a file with different properties,
simply sticking that file into the middle may no longer work, and you
might have to re-encode the information. The structure is actually
more complicated for movie files, since instead of a single header
with tags, you have a "container" that holds both the audio and video
parts of a movie, with separate atoms (like "tags") for the various
metadata.
I believe QuickTime Pro (paid) will join movie files, and allow you to
operate through the GUI interface. I've also heard that MPEG
StreamClip will handle this kind of operation. Probably someone like
Darcy Burnard could comment on this, since I don't know whether these
work with the output formats that Sarah wants. I've only really
explored this subject in the context of working with audiobook files.
Here's the page for MPEG StreamClip to check for more information:

HTH. Cheers,
Esther

Well, it is going to get a little more involved, but you can do the
fallowing.
this will strip the header from file1, contatinate it with file2,
and write the final result to final_file:
sed 1d|cat file2 /dev/stdin>final_file
This is assuming that the header is 1 line. you need to know how
many lines it is and replace the integer in the sed command
accordingly.
if you have a bunch of files who's headers need to be stripped:
( sed 1d file1&&sed 1d file2&& so on )|cat file /dev/stdin>final_
file
It might be a good idea to play around with this on simple text
files just so you know what order you want the files to be in.

Except the headers in teh *.mov files might be different so youtube
might not play them. Basically I read an artical on how to merge
*.mov files in QT but it involves draging and dropping. I've tried
several other programs including imovie and tht didn't work.
Take care.

Hi,
I'm not sure exactly what you are trying to do, but if all you are
doing is concatenating files you can do the fallowing:
cat file1 file2>file3
That will merge file1 and 2 putting the contents into file3. You
can type man cat to learn more about how to use it.
There is also a merge command that is useful for merging changes
in to or more files.
hope that helps.

Oh I did and I found out it might not work. I need another
method of doing this with a gui.
Is there a program that will merge mov files and be accessible.

Sarah,
Hit control-c to shut down the cat util.
It doesn't mater if a file name has spaces. you can saround it
with quotes, escape the space with \, or use tab. The tab
completion applies at any time.
The cat command expects a file name, and if it doesn't have one
in it's parameter list it just sits there. Any time that
happens, use control-c.

I did. Now I can't get the cat command to work. it sits there
with no output or errors

Can you rename it in finder? Find the folder from finder,
press Enter, and give it a name without spaces?
