Even that probably nobody here has used this new recorder before, I wish
to get viewpoints and suggestions as feedback before I possibly go for
this solution myself. Maybe I oversee something?
First my selection from the manual:
/Datavideo Technologies //DN-300 can record HDV via the IEEE-1394
(iLink, FireWire) output from HDV Camcorders (.m2t), or DV from DV or
Analogue video sources (.dv).
The DN-300 can be as an external firewire drive from which files can be
dragged and dropped to a PC or MAC. The DN300 also has a built in
utility to convert .dv files to .avi files.
Interesting, but pricey. I would have been tempted if it came with
a battery. It certainly has more compelling controls than the CitiDisk,
which really only has the small size and weight going for it.
//The DN-300 uses a FAT32 file structure, so large tracks are broken
down into 2 GB files which are sequentially named. For example if Track
02 is 1 hour in duration it will appear as follows (max 99 tracks):
dv02.dv (2 GB) - dv02 is the file name for Track 02
dv02_01.dv (2 GB) - Each 2 GB section is given a sequential _xx numeric
extension
dv02_02.dv (2 GB)
...
dv02_06.dv (77 MB) - The last file in the sequence is likely to be
smaller than 2GB.
This can be quite annoying if you need to recode a long recording
quickly. As far as I can tell, ffmpeg doesn't take sequences of
files as input.
2. Is here something that may probibit the files and formats to be used
with Cinelerra as NLE?
Various libs and apps may not recognise or parse the files well,
if they happen to violate the (wrong?) assumptions made by those
libs and apps. Kino and ffmpeg don't recognise the AVI files made
by the CitiDisk, for what it is worth. (but xine can play them)
3. At first I was somewhat doubtful about the FAT32 file system on the
DN-300 disk that did split larger tracks in filesizes of 2GB each. Maybe
this isn't any drawback, as 2GB in practice may be large enough to drag
and drop onto Cinelerra each time?
Sure. Cinelerra can open several files at a time, which makes this
pesky splitting less annoying. Still I would like some file system
backend (an KDE ioslave or equivalent, maybe?) to lump such files
together to hide this kludge.
When are such devices going to use more capable file systems?!
