and Convergent Design has a user forum on Creative Cow. Pretty cool, huh?
Now, what do you give me ?Bob Zelin

you can ABSOLUTELY RAID the two drive (or more than two drives) together at RAID 0 using the Apple Disk Utility. 2 SATA drives stripped together gives you about 128mb/sec – enough to easily do 8 and 10 bit uncompressed SDI, and DVCProHD with NO problems.

This is a great post. It’s a shame that Panasonic won’t allow the standard FW path to record the DVCProHD signal to anything besides the Firestore FS-100. (one day …..)

No offense here Kristian, but I am constantly amazed that Blackmagic continues to support the fantasy that professional video products do not need to be Genlocked. One of the nost attractive features of the yet to be released Blackmagic Multibridge Studio, is the built in black/tri level sync generator, which can feed multiple sources that lock to the Blackmagic product.
This gentlemen currently needs to purchase a color black generator to resolve his problems. These rediculous tricks of looping the Y signal will not help him as his system grows. A Horita BSG-50 is $289 in most mail order catalogs on line, and certainly even cheaper on eBay.
To be clear Chad, you take one output from your Black generator and send it into the Genlock input of your Blackmagic card, and take a second output of the black generator and send it into the Ref Video input of your UVW-1800.
If you are doing an insert video, you should also send black into the Video input of your UVW-1800, even though you are using the Y, R-B input (component input) of your 1800. The 1800 likes to see STABLE SYNC on it’s reference and video input. When you make a black tape, so you can EDIT TO TAPE, this is called an insert edit, and you will need to record that black tape with color black being sent into the composite video input of your Beta 1800.No offense to anyone, please –

yes, but currently it relies on the hardware based on the horrible Highpoint Rocket Raid card series. The stable SATA products that actually work (that you see on these user forums, and that are OEM’ed by G-Tech, ProMax, Lacie, etc) are from Firmtek, and Sonnet. Adaptec, SIIG, Initio, and Aacard are also making SATA host controllers, but these are not multiport, and these do not have the RAID feature.
As I have often stated on these forums, I have installed numerous SATA arrays (all RAID 0) since April 2005, I to date, I have NEVER seen ONE SATA drive fail. Of course, because I have just said this, they will all drop dead next month, but so far, I would not worry about RAID 5 protection, like we used to with the ATA drives we have seen in other arrays.

Mr. Perez –
your ATI card has NOTHING to do with this problem. Continue to keep your FW card out of the system. As Jeremy suggested, download the AJA Kona System Test program from http://www.aja.com/support, and run it on your computer. Even a single decent drive should get 68mb/sec, and your HUGE should do dramatically more than that. I have to assume that you have a current MAC OS operating system, a current FCP version, current AJA drivers, and current ATTO driver for your MAC, that matches the MAC OS (I assume you DID download a UL4D driver from http://www.attotech.com, and did not use the default SCSI driver that comes with the MAC OS – yes, this is important).I assume that if you have done all of this, and you are still dropping frames, then when you run the AJA Kona System test, you will see poor performance (like 12mb/sec), which means that somehthing may be wrong with your HUGE Drive array. It may require a firmware upgrade.
If all the stuff I am describing to you is overwhelming (download this, download that, upgrade firmware, etc – why can’t it just plug in and work !), then perhaps you should hire a freelancer to help you with all of this stuff. Contrary to popular belief, it ain’t easy getting a system to work properly, and requires a little bit of work, which is often done by a Value Added Reseller.
I also ASSUME (and no insult here) that you know to go into System Settings on the FCP Program, and SET the drive to capture to, to the HUGE array, and that you are not trying to digitize to your internal hard drive in your MAC. Because you are not describing all of the details, I don’t want to assume anything.

Bet you don’t have a black generator in your system, locking the Beta 1800 Ref Video Input with the Blackmagic Genlock input.

Running analog component 75′ long is absolutely NO PROBLEM for Blackmagic, or any other video company, including horrible crappy products from Canopus, etc. You start getting into equilization problems (hi frequency roll off) when you start getting close to 1000′ – but 75′, 100′, 200′ – NO PROBLEM. As for cable, generic Belden 8241 (common RG-59) is just fine for this application. NO ONE IN THEIR RIGHT MINDS uses Belden 8281 anymore (except people over 60 years old, and they should be shot). Modern Belden 1505A, Gepco VPM2000, or the more expensive Canare brand will work fine. These are all RG-59 style (and thickness) cables. Using RG-6 thick cable, like old Belden 8281 is CRAZY, unless you need to run HDTV signals LONG DISTANCES over 300′, and then you would use Belden 1694A. There are many fine brands of cable out there – Belden, Gepco, Canare, Clark, etc. Find the old geezer that said Belden 8281, and run him over with your car.
From one old geezer to another –

the whole point of the mixer is to CORRECT for levels – too low – amplify (raise the faders) – too loud, attenuate (lower the faders). I don’t give a crap what is coming out of your source – a too low VHS, or a too hi AJA box – make the mixer read ZERO (or 4 on some cheaper mixers like UB22242FXPro’s), and set your Beta VTR for ZERO VU (using TONE, not average sound level), and you are set. I can assure you of one thing – if you screw with the levels, when your tape goes to a dub house or TV station, they don’t give a crap about your average levels – they care about tone, and if your program does not follow your tone levels, they will complain about your tape. I am sorry that Sony gives us crappy meters on the UVW1800 series VTR’s, but we are stuck with it.

the Beta 1800 audio meters are averaging meters, and will never show proper peak indication. Tone looks correct, but active program ALWAYS LOOKS LOW on the Beta 1800. This is easy to prove by putting a Digi Beta VTR analog audio output into a Beta 1800 analog audio input. The DVW-A500 has peak meters, and peaks all over the place, and the Beta 1800 meters look like they are barely moving, but tone looks correct. So FORGET the Beta 1800 meters, except for tone.
Simply setup your Mackie mixer to read ZERO on the LED meters, make your UVW1800 meters read ZERO (+4dBu), and everything will be fine. You will play back your tape, and say “tone looks ok, but the meters are barely moving in active program” – that’s the Beta 1800 meters. Don’t like it – use a better VTR, with Better meters.
