HD video freezes on playback
Hello,
I’m having problems with my HD video freezing up during playback. I’m working with a Kona2 card and using a Panasonic DVCPRO HD deck. The original video is 720p and I’m bringing it in to FCP at 10 bit uncompressed. My sequence setting is at 10 bit. I’ve tried using several codecs without any luck. Can anyone offer a quick combination or codecs or suggestions as to how to solve my delimma.Thanks in advance,
Dale -

what drives are you running? You need about 150mb/s minimum to run uncompressed HD

Walter,
I’m using xserve raids. -

Yes, I’ve got it set for fit to window. It freezes on the viewer and the HD monitor.

Since you’re originating in DVCPro HD, I assume you’ve tried bringing it in in this (most excellent and space efficient) codec? It’s a good deal easier on the ol’ disks than uncompressed…
If it’s still freezing, your system is either not up to it, or your drives/interface are faulty.

[Dale Fakess] “Walter,
I’m using xserve raids.”Are they fully populated? That is all 14 drive slots (I think it’s 14) are full? Uncompressed HD is only supported on a fully populated Xserve RAID.
If it is fully populated, have you run a speed test on it yet? Are you getting something like 250 – 375mb/s on the speed test?
If not, the drives may not be set up correctly. I know they can be a complete bear to get fully set up correctly for uncompressed HD playback.

Your drives can’t handle the playback. While an Xserve RAID can handle certain flavors of uncompressed HD, often, you need two striped together for better performance, especially longer format shows. My suggestion is to recapture in the DVCPro HD codec and then drop it into an HD Uncompressed timeline before you are done and output from that. If your current RAID won’t bring the noise, you just rent one for the day and be done with it.

Walter,
Yes, they are fully populated. I don’t don’t know what the drive throughput (speed)is. I don’t have access to the admin software, but I will inquire to the powers that be here at work. I’ve managed to digitize the video at Kona2 Panasonic DVCPRO 720p 59.94 8 bit and matched the sequence at 8 bit as well with great improvement, but there are still some issues.Dale

Ben,
What codec would you suggest using?Dale

[Dale Fakess] “Ben,
What codec would you suggest using?”DVCPro HD, keep it native. We’ve delivered over 30 episodes so far to the networks using a DVCPro HD workflow all the way through. Firewire ingest, edit / effects / cc, then firewire back out to the 1200A or direct to HDCAM through the Kona 3.
