problem with firewire output – help please
i’m editing on a powerbook g4 system. everything has been working well. i have
this notebook tied in to my other system for added resources. the setup is now:g4 + lacie 250gb
dac 100 external converter
ntsc monitor
hp 20″ for second desktop screenuntil yesterday this setup was working fine. all of a sudden, though, i’m getting
playback issues. the system either can’t find the external converter or it only
makes intermittent use of it. if i turn external video off, everything plays fine.
with it on, the timeline plays back only for a few seconds (maybe 5), stutters,
and stops with an error message about dropped frames and possible causes.
the message suggests turning off unlimited rt (didn’t solve the issue), closing
sequences not in use (didn’t solve it) and some others i forget at this moment.
the converter seems to be ok as it passes video through its analog side just
fine.i looked at the drive as possibly being an issue. it was down to 7gb free space
so i deleted all render files and rerendered only the sequences i’m working on.
i now have over 30gb free and it’s still doing the same thing.i’m wondering if this is less a fcp issue than a system issue since it seems tied
to the firewire port being open: things play fine with external video turned off,
drop frames and stop with it turned on. also, after refreshing the av devices
via the so named menu option the system seems unable to find the external
converter sometimes.any advice on how to get this working again is much apreciated. the odd thing
is that it’s been working fine for weeks now. that makes me think i really
shouldn’t have to be changing settings that have worked fine up to now. the
fcp settings seem consistent with what they’ve been. i’m wondering if there
could be some system settings outside fcp on the g4 that could have gotten
tweaked somehow and are causing this behaviour.thanks in advance,

have you tried updating to 5.0.2 and the apple pro apps update? if so. trash your prefs in final cut (you can find out how to do this on apple site) it is very similar to FCP4) and if that don’t work reinstall FCP5 and then the update.Try that

MMMM, long post..
I had a simular problem on Monday, kinda weird.. there must be a bug going around or something..
I reinstalled my OS and my FCP, Im kinda back up and running but still having trouble connecting to my decks consistantly..
Any ways thats the best start you can do for a quick fix, check you codec, and extensions too..3 -
thanks for the tips folks. may have solved it. after much googling and
gnashing of teeth (and prefs deletions), all to no avail (sp?), i did
a test by creating a new project from scratch. i imported a random file
(they’re all 23.98) from the problem project’s drive into the new
project. lo and behold, the file played flawlessly on the timeline.
i thought it might have something to do with the new project being so
small, consisting of only a single sequence with a single file. with
the new project open, i opened the problem project, intending to copy
a sequence from the problem project to the new project. i thought i’d
start copying things across, testing playback as i went to see if there
was a point at which the firewire out issue appeared. however, the old
problem project opened and played fine. i then closed the new and
functional test project. the old project continued to play correctly
out the firewire from that point on. makes little sense to me but it
seems to have worked.in a nutshell for anyone else who experiences this:
create a new project at the same settings as the problem project.
with the new project open, open the old project. then close the new
project.thanks again,
BabaG
