G-Raid no good for DVCPRO HD?

[Aaron Neitz]

yes yes, you old hand. You are My point being, if his drive can handle 10bit UC, then it should be handling DV100 just fine. That’s what he was asking about. It can handle 10bit UC, yes only a single stream, but it works just fine.

I think everyone’s missed the point here. Something is totally screwed up with his hardware. I 100% agree that editing DVCProHD on that thing is not ideal and if you can afford that format, you can afford an $800 SATA array. But he’s having trouble playing back just one stream which is totally not right. That drive is more than capapble of it and he shouldn’t have problems like that from just one stream doing regular playback. I’m inclined to think his FW bus is clogged up with other devices, or he has a defective FW drive.

thanks mitch…obviously an internal sata would be my first choice. but i also need an external option. you mentioned you would never use 2 drives. so what would you recommend for a one drive external sata? thanks again mitch.

[Mitch Ives]

Actually, the people I know who have tried DVCProHD off of a FW HD have had nothing but trouble. I realize some people ythink it’s working, but I remain unconvinced.

Of course the real question is: why do people spend so much time trying to make this work?

Actually, I was speaking of external solutions. I wouldn’t bother with a single external SATA drive. It won’t solve your problem.

You can try a two drive external, but I’d get the 4-port PCI card so you can add two more drives in the future, without having to scrap the PCI card. I recommend a four drive external SATA array.

What kind of SATA drives would you use with the FirmTek SeriTek/1EN2 enclosure?

[Vincent Rice] “My statement is fact. FW400 (the digital transfer protocol) is perfectly capable of handling 2 streams of DVC copmressed HD @ 100Mbs. Whether it works in a real situation is entirely dependent on what drives are on one end and what computer is on the other.”

Fact and Reality in video are completely different things. You have substituted your own reality ( ala Walter’s tag line) I have in fact never been able to work on 2 streams of DVCPROHD on a FW 400 drive. and believe me I have tried, and I was showing 720pHD on running on FW nearly a year before FCP4.5 was released with that ability built in.

What the bus can do and what the drives can do are 2 completely different things. Telling people here that it can be done when those of us that work in HD are telling them it can’t be done is a great disservice to the readers of this list. Walter and I alone have probably cut over 1000 hrs of DVCPROHD content, and between the 2 of us we have done our fair share of debugging the HD process.

[Mitch Ives] “I can’t agree with this advice. The G-RAID is marginal (in my mind unnacceptable) for 10 bit uncompressed. Since I’ve been doing 10 bit through SDI longer than most, I feel qualified to say that.”

I disagree- I’m with Walter, I can and do use the g-raid ( and lacie BDE’s) for DVCPROHD editing and 10 Bit UC Standard Def on my laptop. I always run the hard drives from a PCA card NEVER from the system bus. Knowing the problem from the posts, I am going to assume that Eli is not doing this, but trying to capture to the laptop with the 1200a connected to the FW400 port and the G-raid on the 800 port.

Other things that cause dropped frames are anything that is taking attention away from FCP, — CD’s or DVD’s in the machine, itunes running, being connected to the internet, having less than the proper config for FCP ( to capture HD on a laptop you need I gig RAM Min. in addition to the FW card.)
