I'll introduce this subject first by commenting three extracted sections
from the Cinelerra wiki/manual:
1.1 About Cinelerra
There are two types of moviegoers: producers who create new content
and revisit it for further refinement, and consumers who want to
acquire the content and watch it.
Cinelerra is not intended for consumers. Cinelerra has many features
for uncompressed content, high resolution processing, and compositing.
Producers need these features in order to retouch many generations of
footage, which makes Cinelerra very complex.
Well, I'm not a "producer", but that way of working, revisit and further
refinement really attract me. During a learning process in my own pace,
from simple cut editing to progress with later adjustments, transitions
and effects, this method should fit as well.
7. Editing
Finally, editing decisions never affect source material. This is non
destructive editing and it became popular with audio because it was
much faster than if you had to copy all the media affected by an edit.
Editing only affects pointers to source material, so if you want to
have a media file at the end of your editing session which represents
the editing decisions, you need to render it.
Also of great interest to go back to previous steps in the EDL to make
adjustments as above.
5.4 Saving project files
When Cinelerra saves a file, it saves an edit decision list (EDL) of
the current project but does not save any media. The saved file
consists of text. It contains all the project settings and locations
of every edit. Instead of media, the file contains pointers to the
original media files on disk. For each media file, the XML file stores
either an absolute path or just the relative path. If the media is in
the same directory as the XML file, a relative path is saved. If it is
in a different directory, an absolute path is saved.
Similarly if you saved your project outside your media directory but
you would like to move your media to another location, you can change
the paths from absolute to relative by going to File→Save as... and
saving your XML file in the same directory of the media.
If you want to create an audio playlist and burn it on a CD-ROM, save
the XML file in the same directory as the audio files and burn the
entire directory. This keeps the media paths relative.
Now to my real question, what will be the best project practice in my
situation as described in the following?
Still waiting some time for a large and powerful (enough) DV&HDV editing
laptop as a desktop replacement, my available homePC w/Cinelerra on
openSUSE 10.2 is an old, less powerful K7 w/ATI Rage128RF graphical
card, 512MB memory and practical no free internal disk space. However, I
have bought a Datavideo DN-300 DV&HDV hard disk recorder w/250GB disk
that is mounted as an external IEEE1394 portable disk. Therefore I have
available rich space of captured DV media tracks (in the first phase).
Can I start on this platfrom with simple cut editing and with all media
on the external drive? I think the best will be to save the EDL in the
same external media directory, to use relative path pointers. This also
to write project at intermediate readiness with DV media by burning them
later on rewriteable 50GB Blu-ray disks.
Do I need to configure Cinelerra especially to work this way?
At last I wonder how the Media directory in the Resources window really
does work? What is the path to its default locations and where can I
possibly customize this path to the external disk if required?
Is it neccessary to first drag all media clips into the Resources window
to make them available for editing? What will this Media directory
contain, pointers to the media clips or the real video media clips itself?
