Cineporter Update

I'm a little confused about your post, 720 vs. 1080? What do you mean?

I believe he is referring to data rate. 1080 is about 100 Mb/s. As far as I know, you need a RAID for that (RAID 0 striped, RAID 3 or RAID 5).

I want your product, though. Release it today and I'll give you my Amex number! Looking for Beta Testers? I'm your guy!

I can be perfectly content with 720P and 720PN for at least two weeks. Actually, won't be doing any project in Hi Def till summer. I'd be using it for DVCPRO 50, which I'm sure your Cineporter can handle.

Referring to an earlier post, I'd prefer mine locked beneath my rail mount on the tripod once you get the gyroscope effect resolved, by the way.

Looking forward to your release!

Mike, you can send me an email and we can add you to the potential beta-test list, which is a mile long. We have already chosen most of the beta testers, unless you feel you have something special to offer?

What resolution are you expecting regarding the gyroscopic effect?

David - thanks for the mass email today clarifing your stand on the non-refundable deposit. Previously i felt like a hostage held on $500 ransom... not knowing when you will get the camera, while others who ordered yesterday got the camera today. :)

Now, It leaves a very positive effect on your company!

I currently have a 300Gig Medea video RAID SCSI, striped in RAID 0 which runs at about 30 Mb per second sustained data rate. Great for DV.

I also have a 500 Gig G-Tech G-RAID, which guarentees 50 MB/s in a Firewire 800 Port. It is two disks striped for RAID 0.

My internal system is an Ultra 320 SCSI controlling an internal Atlas 15K SCSI which only has a maximum sustained data rate of 75MB/sec and it claims to be the fastest hard drive in the world.

I've read the Firestore is having difficulty with the JVC's data rate, which is less than 30 MB/sec. I want to know more about their drives before I invest. Plus, I'm a big, clumsy man who will most likely yank out the firewire cord during the perfect take or the most important moment of my shoot.

I'm not saying the Cineporter can't do what it claims. I really want it to! I want to buy a device that has more data storage than the P2 cards that attaches to the camera. I'm a geek and I almost get a woody thinking about a drive that plugs into one of the P2ports! I'm hoping that in the year and a half since I bought my system, these smaller drives have begun kicking major ass.

I'm rooting for you guys to succeed!

I would be happy right now if your setup would just do DVCPRO 50.

Sent an email when I got the camera, so I'm probably about 3/4 of a mile down the list. I can wait till release. I'm not actually shooting Hi Def till summer. I will be shooting DVCPRO 50 and a lot of greenscreen stuff before then.

Just enthusiasm and a willingness to invest money to buy the hardware I'm using during the pre-release program..., as long as when the product is in final release I can upgrade to the final product. I am presuming the Drives will be the same as in your final release.

I'm most interested in the larger version, 320 Gigs. Right? Eventally having the option to be a RAID 1 with a firmware update.

I'm basing my comments on the gyroscopic effect on comments made in the "Hardware" thread. Your solution was smaller drives.

The only reason the gyro-effect even popped up is because my mother-in-law is a scientist at NASA designing equipment to make scientific studies on the space station in Mars gravity.

In a scenario that seems all too familiar at NASA, the left hand wasn't talking to the right hand and after the equipment was designed, they finally told the Space Station folks that there was a centrifuge involvled there was a melt down. A gyroscope on a the space station would effect the entire station's positioning.

So, unless the spinning hard drives REALLY spin (ever held a hard drive while it's spinning?) you're okay. Your techs are sure to tackle this problem, if there is one.

Thanks for responding.

I think there's some confusion here between MB and Mb. Your drive claims it can do 75 MegaBytes per second, DVCPROHD is 100 MegaBITS per second, so DVCPROHD is one eighth the data that a 100 MB stream would be. So a drive that can handle, reliably, 20 MegaBytes per second should have no problem with DVCPROHD, even in the 1080 format.

Ah-hah! That pesky old BITS BYTES thing again . . . confusing (thanks for straightening that out).

I wish they had named it something else . . . maybe bites boogers?
 
Ok a IDE HD can do 40 to 50 MB/sec easily... Now if you have a Strip, with a few disk, you should get easily 100MB/sec and higher. I get 245MB/sec with my 5 250gig HD SATA in Raid 5.

These numbers drop if you do random access, but since video are big file, you make sure everything is sequential and use big cluster size.

Yes, you're right. I forgot. I stand corrected and I apologise...

Maybe it ought to be renamed MegaBytes and MegaNibbles.

I just read "megaboogers." I like that better.

I hear the data rate for 720 is the same as 1080, but in practice, for some reason, it seems as if it really is not the same. I would love to be proven wrong, but I don't see a hard drive based streaming system to be a reality for another year.

My point is that personally, I am willing to take the route of buying what is available now, instead of waiting for a wonder product like the cineporter.

Again, I think the product will be great, I just don't feel it will be able to stream HD footage untill the bottlenecks are worked out. If it were easy, it would already have been done. There are already products to do SD, so I imagine that the only difference is increased bandwidth. If that be the case, a solution should have been found by now. I am not saying the product is bad, or impossible, just that the data rates in question have many bottlenecks to deal with before a reliable stream can be repeated. I may be way off, I am just basing this on the things I have so far seen or tried.
 
I'll say it again. Data rates in this instance are not at all an issue, unlike in an editing system, which has to decompress the footage to deal with it on the timeline. There 720P and 1080p are in fact, totally different. that's why you need a more capable system to deal with 1080P

As far as waiting for our product, I agree, get what works for you and when you need it.
