playback starts fine, then begins dropping frames…finally halts playback
I’m a fairly experienced FCP editor and I can’t figure this out.
FCP7 – Matrox MXO2 – Snow Leopard – XDCAM 420SP (wrapped in Apple HDV 30p 1440×1080 container)
I’ve ran speed test – average read/write of 230 MB/s
Running on internal software RAID-0 (3TB, 300GB free)
Everything seems to be up to date regarding MXO2 firmware. I’ve rebooted, running no other programs. It seems to run faster if I let FCP sit idle for a couple minutes…it will play longer without issues than if I keep trying to play over and over. I’m wondering as I’m typing this…how much space do you need free on a RAID? It seems to be a bottleneck issue.
I’ve had this issue before, and it’s resolved itself. I’m hoping someone has some insight.

Your RAID is simply too overloaded.

Only 300GB free on a 3TB Raid? That’s not much room left.

I don’t think it is your raid array. You did not specify your CPU or RAM. Are you on a g5?
HDV takes a lot of CPU power to decode and play in real time. I would suspect your CPU of not being fast enough – even the newer Inter machines battle to do HDV.XCDAM 420 wrapped in a HDV container…
What is your timeline settings? HDV is always a bugger… I would suggest converting all your HDV to Apple Prores or DVCPRO HD for far better playback performance.
Or place your HDV clips on a Apple Prores timeline and render.

16 gig of ram…not sure of g5…but it’s 8 core, purchased highest end Mac u could buy 1 year ago. Regarding codec, that is the container I get when I rewrap the mxf files off the xdcam disc with the 420sp setting on a PDW700.

And…sequence settings match clip.

Hi Jason
No, then it is definitely not your CPU or ram….
How did you bring the footage into FCP? Log-and-transfer would normally transcode incoming footage into Apple Prores. If you used the Sony import program you are stuck in their codec. HDV sucks. I would try to transcode overnight – use Media Manager to go to Prores.
Hope it helps

[Francois Stark] “Log-and-transfer would normally transcode incoming footage into Apple Prores.”
I use the XDCAM transfer import function…which does NOT transcode, but wraps the video in a different container than the native MXF format from the disc. I can shoot in 3 formats on the disc – 422 50 / 420 HQ / and 420 SP. The 422 50 comes in with an “Apple XDCAM HD codec” but the 420 SP comes in with that HDV codec.
I need to figure out how to come off the xdcam disc with a less compressed codec, but there aren’t any options coming through XDCAM transfer.
