It’s working now, so could be the steps i took to clear things up. Hopefully it keeps working.
I’m also preparing to set up a RAID 0, so this should help more I would think. The error message did say something about “streaming”, so it did not seem to be a timecode or dropped frame issue. I wonder if capture now is safer than batch?

I was never wanting to capture 10 bit for this hdv footage. But even with 8 bit, I’m wondering a couple things. How much lag time would I get capturing a 45 minute reel over fw without a capture card?
My 48 sec. test capture, i think had about 18% lag time. Would the RAID0 over fw have less lag time even though I’d still be coming in over fw?
Also, re: drive space, even with two 500GBs as RAID0, doesn’t the speed slow down as the drives get more full, so you may not gain anything if you start with the RAID0 half full or a bit more before rendering etc.?

I made the screen cap but don’t know how to attach an image here. i see there’s a tutorial, but i don’t understand it and don’t have the time now figure it out.
i was hoping to be able to tell you a page in the manual but can’t find it there. for sure it’s there in the sequence pre-sets for fcp6

In fcp 6 capture settings it lists a choice for ProRes 1080i 1440 x 1080 as 8 bit. With my test capture at this setting, the “item properties” in fcp showed the clip as ProRes 8 bit.

BTW, it’s a 5 bay Fusion. I did not have this way back in fcp v. 1 (it did not exist). Since I got the Fusion my greatest need was to use it as jbod because of the types of projects I was editing.
Also, I didn’t have the extra hard drives available, and only recently got the 2 new 500GB drives for this project. So this is the first time I think I’d could actually benefit from a RAID and have a couple extra drives to do it.
Just to clarify though, would that mean I can calculate my drive space based on a terabyte? I thought I’d still calculate disk space as 500GB and that the RAID just allowed faster read/write speeds.
Please confirm this – you’re really saying the RAID0 would double my drive “space”, not just increase speed?
I also notice that Hitachi says their SATA II hds are set at the slower default setting of 1.5 in case someone doesn’t have a controller to handle 3.0. I don’t know how to re-set this, and never heard anyone else talk about it.
Hmmmm, although my test capture of a 48 sec. clip worked fine captured as ProRes over fw, (about 18% lag i think) I wonder how it would work trying capture 45 minute tapes. I’d except it if it just meant a long lag and no other problems. I have to capture the full tapes so I can sync them up for the multi-cam edit.

I cleared off (erased) a different hd and now I captured it ok. I’ll try to figure out later when I have time if something is wrong with the first HD.
Another thing I changed, don’t know if it matters in this case . . .is that I unchecked “abort capture on dropped frames”.
BTW, I can’t batch cap small segments because this is concert footage where I need to be able to sync all 3 cameras.

I believe that the ProRes 422 Std. is 8 bit. I think it was Phil Hodgetts post on kenstone.net that said for hdv which is 8 bit, there’s no advantage to using the HQ version of ProRes . . .instead just stay with ProRes 422 Std. 8 bit.
The amount of hard drive space I’d need for this project (4.5 hrs.hdv footage) if I stayed in hdv, would be at least 72GB. If my calculations are correct, I should multiply that x5 to calculate ProRes 8 bit disk space.
So that would be 360 GB, plus need to leave some headroom. On a 500GB drive you start with about 440 GB available space. Seems like that’s risking HD too full.
Again, since I haven’t used a RAID setup before, I’m not sure about this, but I thought that it only increases speed, not disk space.
If I could get my newly purchased MXO working (recognized), maybe that would let me work in hdv and view real time preview playback more speedily. . . just guessing because I’m not sure what advantage it will actually give me.

Yes.

OK, I just ordered the Apple Cinema HD 23″ and the MXO. Thanks to all of you for the input.

This thread is very helpful, thanks.
I can’t use the adc port for my vga computer workstation monitor because the adapter for adc to vga is no longer available and I don’t have one. So the acd with have to connect to the mxo via an adapter to the adc connection. ie., a adc to dvi. Hope that extra piece of hardware doesn’t slow down or cause any problems.
I guess the Kona LH pci-x would fit my G5, but it’s more bucks and I could never figure out if the features are something I’d need.
So, I’m pretty much sold on getting the MXO.
