You've probably lost more income trying to find a workaround for a $150 solution. I do understand. Just also recognize that Mac and FCP is all new to me as of June this year and I really only began using it/them in Sept/Oct having previously been PC and Avid....

the bigger point of my post was that you stated it was playing back "as if it were DV," when in fact IT IS DV once you transcode it to DV. Just making sure you realized that you really are throwing information out the window. Also, mpeg2 is a delivery coded, not an editing codec. The HMC150s are great cameras, what I use every day. Love it. Great workflow. RAIDs are cheap to build into a MacPro, just build it now. You've...

I'm not sure where you're getting the 144 Mb/sec figure from. Aja says ProRes 422 (LT) has a target rate of 102 Mb/sec. That is about 12.75 MB/sec. So, if you have three tracks of that, you'd be pushing less than 40 MB/sec. If some of those data files were living on the inner tracks of a single Seagate, the throughput of the drive might be approaching 50 MB/sec, which is marginal for reading three files as described above. You...

BTW AVID MC (as of version 4.03) will not edit avchd (it will import via AMA DVCPRoHD and AVC-I). Also, if you convert to DNxHD you will probably get similar issues with the drives. If you are thinking of using Adobe PProCS4 for long projects, I wish you luck! FCP will do what you want if your setup is right. I know people who complain that the output from FCP is rubbish and much worse than they were used to getting. A quick check of their...

How many streams of video are you editing simultaneously? You indicate multicam, but you haven't detailed what sequence settings you have, nor which of your computers, and what specific media drives you are using. MacPro 2.26Ghz 8-core Nehalem 12 Gbs RAM   Mac OS X (10.5.7)   GeForce GT 120 512 MBs RAM 30" ACD  

Your single hard disk, when empty, can not likely generate a data though put higher than 100-110 MB/s. 300MB/s is a theoretical limit. Download and run AJA's System Test. It can be found in the Kona 3 tools section of the AJA website. After you know what your system's capabilities are, you can make some reasonable choices. x 512k MacPlus with 40MB external SCSI drive   Mac OS 8.6 or Earlier    

BTW, what is mean by layers of video? There's an illustration of a FCP timeline with multiple layers in this thread: http://discussions.apple.com/thread.jspa?messageID=10516184&#10516184 Mac Pro 8 Core/Mini/3ACDs   Mac OS X (10.5.8)   FCP forum elitist (PAL B/G)
