10-bit uncompressed not playing smoothly
I have recently had problems with LiveType text rendering in FCP 4.5 with problems. Thankfully, someone in a Creative Cow post helped me by suggesting that I change the sequence settings to 10-bit uncompressed instead of the DV codec. This certainly fixed the appearance of the text, but now my 17 inch widescreen, 1.5 GHZ PowerBook with 1GB RAM won’t play the sequence smoothly. Is my PowerBook not powerful enough to play this sequence? Any other thoughts. Thanks.

Your drives aren’t fast enough. You need at least a FW800 RAID unit like a G-RAID or a SATA or Fibrechannel array to play 10bit uncompressed.
Internal drives, FW400 drives and many FW800 drives can only play DV and maybe 8bit uncompressed.

Thank you very much for clearing this up for me. I appreciate your input.

Go to the AJA website (www.aja.com) and download the AJA Kona System Test. It is an independent app that will test your drives’ speeds. It will tell you MB/s and also can display how many streams in each resolution the drive will support. If it dips below 1, you know the drive isn’t fast enough for that resolution.

Thanks for that post. I’ve been running the tests on my FW400 drive and can find how many MB/s my drive runs at, but I can’t find a listing for how many streams it’s capable of. I’ve tried all the tests and opened the text and graph options, but haven’t found anything listing streams. Am I missing something obvious?

look in the system test preferences.

My bad. I’m still learning the mac and looking to the top menus is something pretty foreign to me. Thanks for the point in the right direction! I noticed a couple strange things, but didn’t want to hijack the thread anymore, so I posted a new thread describing my results of the test and how this doesn’t seem to make sense to my experience.
Anyway, thanks again!
