Video freezes every minute or so during capture.

[Bob Zelin]

I made a typing mistake in my last post – I said 708mb/sec (which is more than fast enough), when I meant to type 70mb/sec write speed (which is about what you said you were getting).

Sorry –

The freeze is happening when I capture. After the capture I always check to see if it captured correctly. When I play it back I notice it freezes during playback. I can tell it happens during the capture process because I can play that same section where it freezes over and over and it will always freeze in those same spots. It plays the footage back like it was shot that way. So something is hanging up when I capture the footage. I am also having issue where after I log a tape, I will go to capture that footage and it will tell me my tape has up to ten or so timecode breaks which is strange since its one continuous shot. There shouldn

[Nick Balogh] “So after a day of inputting footage its starting to freeze again. I dont know what my options are at this point just short of reinstalling everything and re formating and re-striping the drives. Ideas?”

Please tell us you do NOT have journaling on.
your drives are fast enough to capture the footage you are writing.
you have nothing running in the background
— itunes, norton utilites/systemworks/ you are connected to the net running a duplicate or unlicensed copy of FCP —-

anything that is not being used is not turned on.
No CD or DVDS in machine

Im not sure what Journaling is…so i dont know if its turned on or not. I have no other applications running annd no other duplicate programs on the network.

Journaling is an enhanced directory structure that allows Spotlight to operate efficiently, the process is time and data intensive
when we are talking about large volumes like your xraid.
Check in the disk utility to see if journalling is on which is most likely – since you did not know about it, you did not know to turn of off for volumes when using them for video capture.

I checked in the Disk Utility and under format it says : Mac OS Extended (Journaled)…so im assuming its journaled. Do i have to reformat and re RAID my xServe to get rid of that?

[David Battistella]

this has been a good thread. There is only one other thing I can think of. I can tell you that one thing that will cause freeze ups in NETWORK ACTIVITY. I have found that if there are programs running in the background that are using the network you can run into problems when capturing or playing back.

Is anyone accessing the drives on a network? Is your file sharing on?

The only time I have seen things like this is when I have had software update runnig in the BG or soemthing during an output.

Besides this you are getting awful performance out of your raid if it is running at 70mb/sec.

My Huge 4210 Drive full populared in a raid 3 with 4gig fiber gets close to 480-520 read writes. So something is most definitely wong with the RAID card/setup.

Slot 4 for drives
Slot three for KONA Card

Wow….so we all agree I

[Bob Zelin]

you cannot just turn off journaling. you must reformat your drives as OS-X Entended – NOT OS-X Extended (Journaled). And YES, you will lose all your material, and YES, it’s a nightmare.

DO NOT PROCEED WITH ANYTHING until you see over 200Mb/sec from your XServe RAID as viewed by AJA Kona System Test. You should get dramatically better performance than 200mb/sec with 14 drives (over 300mb/sec, but I forgot the exact numbers). You said something like “should I get a new drive from Apple” – I don’t know what you are refering to, but ONE DRIVE will not resolve anything for you. You have a RAID issue that MUST BE RESOLVED before you proceed. NEVER EVER speak to the Apple support person you mentioned earlier. He is an idiot, and has no idea of what he is talking about if he said your RAID was performing properly.

This thread is proof that a professional must configure a system. These things just dont’ turn on and start working. This ain’t an iMac.

I got Journaling turned off through the Terminal. When I check it now using the Disk Utility it says its off and that its Format as Mas OS Extended. But your saying not to trust that and I have to re format the xServeRAID?
