Capture slowness with Tiger+FCP5
We are having an odd problem with our Decklink Pro and Decklink PRO HD cards that
happened as soon as we upgraded to OSX 10.4.2 and FCP 5.During capture mode the response is very very very very slow;
each click on some setting or option causes the spinning beach ball for many minutes; if you are patient most functions will
eventually work, but a five second clip could take 8 minutes to capture!In SD mode on a G4, this happens for any capture setting that uses the card, e.g. NTSC-DV which we use a lot
(SD video IN converted to DV for editing) capturing to LaCie Firewire drives.
In HD mode on a G5 with Xserve RAID it only happens using HD capture modes;
if we capture HDV from a deck or in non-HD mode if we invoke DV capture (bypassing the card) everything is fine.If we reboot either machine back to Panther (10.3.8 installed on the other internal drive, with FCP 4.5) everything is normal.
Of course we’ve tried trashing preferences, removing and re-installing the drivers, fixing permissions – nothing seems to help.
We have NOT yet invested the several hours it will take to trash everything and re-install Tiger and FCP5;
is that the next logical thing to do?Or has anyone seen something similar with a possible solution?
Thanks for any help; our heads are getting sore from all the scratching!

[weaver] “We have NOT yet invested the several hours it will take to trash everything and re-install Tiger and FCP5;

Hard drives are so cheap now, just get a new one and put it inside in place of your old one. That way you can keep the old one as a backup. http://www.newegg.com has 250gb Maxline III ATA drives for $97.00 now. Cjheck it out at https://www.newegg.com/Product/Product.asp?Item=N82E16822144236

Yes, we did exactly that; we installed a new system and FCP5 on a freshly erased second internal drive
in an attempt to avoid upgrade problems.Unfortunately in this case, it did not quite work; however everything except capture via Decklink is working great.
Being able to go back to Panther has so far turned out to be invaluable as that’s the only way we can capture
footage at the moment.OUTPUT via Decklink is not affected so older projects opened and converted play back just fine.

Hi,
Here are a few things you could try.
1. Erase your disk array to eliminate any file fragmentation or directory structure fragmentation. You might not want to do this if you value the files on your disk array! In that case see if you can copy them on to another array and then erase. When you reinstate your files, they will be optimized.
2. Ensure no antivirus software is running as it will very likely have a detrimental performance impact on video or audio work.
3. If all else fails, you could try adding your disk array and/or system disk in to the privacy section of the Spotlight PrefPane. This would ensure that no indexing was happening when working on video. I’m not sure how much help this might provide but it is just a thought.
