Terje,
I'll respond by telling you how I solve these questions usually ---

As the manual states, the "session file" is really only comprised of text.
As long as you don't render and re-include the rendered (new) media files,
all your editing is "virtual".
The only real practical problem is to cope with the path to the source
media files, because saved literally within the session.
If the project is not too large, the solution to save the session (XML)
file alongside with the source media works just fine. But if the project
is larger and maybe even includes media from various external disks,
or is comprised of several session files using the same source material,
things are more complicated.
In the latter case, I use the "symbolic links" feature linux provides.
I allways acces my project via a very short assembly of symbolic links,
and thus am able to move and reorganize the real storage freely.
I'll give you an artificial example.
Assume the following:
- - the working directory of my project is /home/ichthyo/stuff/cin/xyz/
- - I have mounted an external disk with the media at /mnt/external
and this disk contains the media in video/summer07/
Then I build an new subdirectory /home/ichthyo/proj and I use an
symbolic link from root directory, e.g. sudo ln -s /home/ichthyo/proj /proj
which creates a link /proj --> /home/ichthyo/proj
Then I proceed to do similar within the "proj" directory: I make symbolic links
"session" and "data":
cd /home/ichthyo/proj
ln -s /mnt/external/video/summer07 data
ln -s /home/ichthyo/stuff/cin/xyz session
Starting from this point, I access my session *solely* via the symbolic links.
I.e. I start cinelerra as
cinelerra /proj/session/mysession.xml
and within cinelerra, I enter the "open media" box, and there navigate to "/"
and from there on to "proj/data" (which actually points to
/mnt/external/video/summer07,
but cinelerra doesn't notice that). There I'll find my media files, selct them
and add
them ("create new resources only") to the "Media" folder.
The net effect is that the session file only contains the "virtual" pathes
created
with the help of the symbolic links. Later on, whenever there is the need to
work
on another computer or to mount the data disk differently, I'll just have to
readjust the symbolic links.
Now, maybe this seems overly complicated or even daunting at first sight,
it well pays of, /if the project is larger and more complicated/
If, on the other side, you have just 5 media files and one session, it is
best to put all in one folder.

HaHa, I *never* succeded to figure out in which directory the "open media"
dialogbox
opens as default location -- but finally you can navigate to every location you
want. :-P
The "Media directory" in the Resources window is only a directory with pointers.
It contains an entry for each media file you loaded, together with the technical
data of this media file (frame rate, file type). The Rest of the session just
references this media entry.
If you are curious, I really recommend you the following: create a *very simple*
session with just 1 video track and a single media file. drag the media file to
the video track (to create a clip). Save it. Close Cinelerra and open the
Session.XML
file with a text editor and look how it works (hint: search for the path of the
media file). There is really no magic involved here.
In the top part of the session file, you will find the "Media directory"
represented
as
<FOLDER>Media</FOLDER>
<ASSETS>
<ASSET SRC="/proj/data/t1.mov">
...
...
and at the bottom, you will find the representation of the timeline.

No, it's not necessary to drag anything. You need to have loaded all media
you plan to use once into the Media folder. Make sure you have the setting
"create new resources only" when opening the media files.
This just creates new media entries.
You can then open them by double click and review them in the viewer.
I'd advise to create some pre-selection there (by using the in- and out-points)
and saving them as clips. (press button "i") These pre-cut clips will show up
in the Clips folder. You can load them and refine them, and finally drag
the clips you want to the timeline...
hope this helps...

PS: always backup your session files regularilly! Do it really.
When Cinelerra crashes, and the internal restore facility fails,
you may need the backup.
PSS: to backup only the session file is sufficient, because Cinelerra
never changes anything at the source media files (unless you advice her
to overwrite a source file with a rendered output file ;-)
