In around 1996-8 when cpu speeds were up in the 250mhz range SGI and SUN work stations were using multi processor multi lane architecture to achieve the blazing fast speeds of the day. I remember the 4 processors but I’m not sure about 8 processor configuration but this technology is nothing new. Apple 9600’s were the absolute bottom of the totem pole and windows NT wasn’t out yet or it just arrived enabling video editing on the pc. It’s surprising dual processors took so long to materialize. With this kind of power and if Apple can unify shake more closely with FCP we could see some of Discreet’s real time performance capabilities on our macs. It’s all about power and flow.

Apple certified training in a class room enviroment is typically about $1500.00 for 3-5 days depending on the level.
You can see the levels and coarse guide lines here:

Are you using the mpeg2 for dvd? m2v and aiff audio is the 1st step and muxing them into a transport stream is the next step. A dvd authoring program will do the rest. DVDSP etc. I think toast 6 and up will mux and burn your files to disc. I’m not sure where you are going with it. If you are tight for space to make a disc you can encode audio with the dolby 2.0 option which is ac3 and about 1/5th the file size as aiff.

[Peter Wiggins] ” I believe you have to have an invite too.”
With all those king size meeting halls?
Yes, it is nice that Apple anounced this special event this year and it should be better than the phoney SF keynote in January. Steve jobs did mention there were some really big things going to be released in the next few months for the Apple Pro crowd. NAB is about video and we are probably the biggest user base of Macs. With all they have been buying in the last year you wonder what is shaken and where the heck is panther? man that cat is too stealthy, I want to see it! I wanna be ridin that bus on the eight lane hiway in Vagas!

If you go with 2 duals get the 2 matching dells. For long form docs you can stretch the timeline across both of em and they will line up nicely. Better to be too big than too small.

To elaborate: Televisions are made of an array of phousphors suspended in the front of the screen in rows. At the back of the tv tube are guns that shoot electric impulses at the phousphors beginning at the top row in the left corner and moving to the right side, then jumping down to the 3rd row of phosphors and energizing that line from left to right and onto the 5th row, 7th row, 9th, etc. till it gets to the bottom of the tube and the guns focus on the 2nd row, 4th row, 6th row and so on(even lines). The odd numbers are the 1st field and the even numbers are the 2nd field. It takes 1/60th of a second to scan each field and it take both fields to make a frame. Thus 1 frame is 1/30th of a second. (ntsc) and is made of all the odd numbered lines and all the even numbered lines. This is interlaced scanning. Progressive scanning starts at line one and then jumps to line 2, 3, 4, etc. so there are no fields, when the guns have gotten to the bottom of the screen a full frame is complete. The first video cameras used tubes that were built like a crt tube in reverse. We no longer use tube cameras as we use CCD arrays to capture the image instead and crt’s (cathode ray tubes) are being replaced by lcd array screens and plasma monitors but this is still the way a video signal is processed, in lines from top to bottom, left to right.

Sata arrays require an internal host adapter in your pci_ slot. You don’t need a BM or AJA video card to use them. They are independant and become part of your computer. You would be better off just adding a 2nd. drive into your G5. That would be the cheapest, simplest, and best solution if you have not already filled the spare sata bay. USB was not intended for video, not even dv. Chances are the drive found in a USB only external drive is only a 5400 rpm hard drive intended for office work.
On the other hand if you are slowly building onto your system than a Sata External Array and host adapter would be money well spent. -
Sounds like this salesman’s a purist or a perfectionist rather than mis-informed.
I’ll share a precious experience I once had with a mac salesman that has become one of those classic memories. I went to see Mike Evangelist demo FCP1 in Vancouver when it was 1st. released. I’d read Steve Mullen’s review of the beta version a month earlier in Video Systems Mag and was anxious to see FCP perform as I was ready to by my first comuterized edit system at the time and was hoping for a mac based system. I came home from the show with the software and now I went to get the hardware locally. After haggling with a mac salesman for a short while he asked “why are you buying a computer anyway?” “To edit Video I replied” YOU CAN’T EDIT VIDEO ON A MAC! He retorted, “Boy oh boy you’re looking at the wrong computer buddy”… “Steve Jobs would love to hear this guy” I thought. Dumbfounded I went over to the mainland and bought my G3 there where at least the Mac dealer made an attempt to answer my questions and satify my needs.
Another time I needed to set up a dubbing system out of town on the road so I went to the local circuit city to see what deal I could get on some jvc decks. The saleman promptly tried to divert me to some hitashi decks explaining that Hitashi had just bought out JVC. Wow I thought, why haven’t I heard of this or read about it. After a few minutes I realized this salesman would tell me anything to make a sale. (I went to an independant store and paid more for my decks)
So we have the swindlers, the mis-informed and sometimes some genuinely knowledgable sales people out there but the bottom line is do your homework yourself before you buy. There are some good points on this thread.

What are your current sequence settings? If everything is rendered and playing in fcp you should just export using compressor and try best quality 150 minutes in the settings. It sounds like you are changing your video setting too as well as encoding to mpeg-2.
What is your proccessor speed in your G4? DSP4 will barely run on G4’s but I don’t remember about ver.3, I went from 2 to 4 but I know 4 would barely run on my dual 450 G4. I only use compressor for short projects but it is never that slow on my dual 2ghz G5. I use a hardware encoder and finish in DSP.

q[Cade Cruickshank] “other application is student video projects and web video.”
Don’t forget you don’t have to capture HD resolution with these things. For student and web video you can shoot DV25/50 resolution and squeeze a lot more on the cards. If your equipment budget is an annual expenditure then definately tape stock will factor into the cost here. For the average guy who picks up media as he needs it it’s not that big a deal but how much is your facility spending now annually on tape? Any one who consumes a lot of tape annually will appreciate the cost of P2. The new cameras coming out with the AVC-I codec option will squeeze twice as much HD on these cards too. The future of P2 looks bright.
