Jim has offered to send you literature on the Max and you can info on the PAR from Greg Pyros. I agree with Jim that there is room for both systems depending on your application. I have a PAR but would certainly consider the MAX depending on your needs and requirements. The PAR is about half the price but won't ultimately have all the advantages of the MAX which has yet to be released. If you don't think you'll need to get into video editing or the potential higher quality of field recording the PAR is a great machine. The MAX with the Illuminator Pro (not Animator Pro… Jim got confused here, <g>) will have many other possibilities including non-linear editing. Suffice it to say both systems are good it will mostly depend on your budget and long term objectives. For someone just interested in doing animation the PAR is more than adequate. If you've got the budget and can justify the additional expense of the MAX, which also requires an EISA motherboard BTW, you'd be glad to have that system as well. I don't think there's really a need for posturing. While the MAX has yet to be released preliminary observations look very good. The point being, for once you have two excellent choices and it will depend on your needs and budget which you choose to go with. -JE

John, Thanks for your input. I am begining to think the PAR would be adequate. We already have a non-linear system (on my network) and a BetaCAM SP and 1" edit suite. One question I have is on the input capabilities of the PAR, can I grab a series of frames to be used for a rotoscoping texture map with the PAR? Also when will the MAX be released? Thanks, JImbo

James, If you buy the optional TBC list $995 you can grab frames to the PAR. But when you say we have BetaCAM SP and 1" then I have to pause and ask what level of quality you're expecting. For industrials and Flying logos to be supered over video the PAR would be fine. But in my opinion for a professional edit suite, I would want the MAX. The reason being that ultimately it will allow a transfer rate of 7+ MB per second as opposed to 3.5+ MB a second. The way this is accomplished is that alternate fields will be stored on seperate SCSI drives, which means you have half the compression and that much higher picture quality as a result. As far as its release date that question was still open as of NAB. They've been working on it quite awhile. I would recommend the PAR to the vast majority of animators but in some cases the MAX is definitely going to be the way to go. In your case I would recommend that you take a look for yourself at both systems. I'm very happy with the PAR but for high end I don't use it. It is a wonderful tool for an animator as it allows you to do alot of tests very quickly, which spares the wear and tear on a Beta SP or 1" machine. For final output I'm still using an LVR in many cases. It depends on the budget and the quality requirement. -JE

Seagate has new SCSI drives coming out that are an array of two in one drive. This should be really cool. Also, the MAX is not limited to arraying 2 drives. I think it really depends on how the array is implemented in hardware (scsi controller) and software. So, with enough HD's, you could potentially have zero compression. Unfortunately I don't think the 1st rev of the MAX will support arrays out of the box. That'll probably be a later software revision or something. But with that Seagate 2-in-1 array drive you'll have an array without even trying! John Tissavary (LUNA cie)

>> I think it really depends on how the array is implemented.. << Maybe, but it seems that there has to be a pipeline to take advantage of the array. If there are two processors you could split it up into four, but I'm not sure how it will work with only one processor, and would you really want a single image scattered over four dedicated drives? I don't know. -JE
#97395From: John TissavaryApr 15, 1994 11:59 PM
I'm not sure I understand why one would have one image scattered over several drives. I would think the array software/hardware would distribute frames (not "a" frame) in a certain pattern over the several drive array so they could be streamed back nice and interleaved-like, but I really don't know very much about this stuff. What does this have to do with the number of processors (innocent question borne out of array ignorance)? thanks, John Tissavary (LUNA cie)
#97415From: John EllisApr 16, 1994 2:49 AM
John, The way the MAX gets double the throughput is by dividing a frame into two fields, each field going to a seperate drive. I extrapolated from there. So that if you had four drives say, to maximize the throughput you'd have to split the fields again. Just a speculation, but how else? Just having multiple drives won't help. If you split the images up into fields then you are pushing half the data and can go for lower compression and therefore better quality. The PAR will soon have the capability to mount two IDE's but this won't affect the compression ratio as you won't be able to split the frame into two fields. Supposedly Matrox is working on this technique although it won't be offered in the first generation as you know. -JE
#97465From: John TissavaryApr 16, 1994 4:23 PM
Ah. I was unaware of how they actually implemented the array playback scheme. It seems they could go one step further, and simply distribute the fields/frame accross the array, and have them stream back. There are plenty of DDR's out there that use arrays. The new HP and Sierra Designs "VDR's" have something like 8 HD's and play back the images from a "segment list". I would have though this is how the MAX would take care of it.

>> It seems they could go one step further, and simply distribure the fields/frame across the array, and have them stream back. << Not quite so simple. The problem is still the through put of the hard drives which is a determining factor in how much compression is necessary to stream a 24/32 bit image in real time. There's several other factors like BUS speed which is why the PAR communicates directly to its IDE for faster transfer. The new drives coming out are reported to have transfer rates of 15 Mb sec which in terms of compression will be essentially lossless. I know IDE's are being developed and Micropolis has been able to achieve similar transfer rates with IDE's and SCSI's, so its a fairly reasonable assumption that an array of the kind you'd like to see will also be possible in the near future. Just keeps getting better, don't it?! <g> -JE
#97494From: John TissavaryApr 17, 1994 3:58 AM
I'm gald to hear HD technology is advancing to the point where one drive can do 15mb per second. That'll certainly change the face (and price) of DDRing! John Tissavary (LUNA cie)
#97501From: Don LandisApr 17, 1994 9:26 AM
What I would wish for is to just let the faster IDE drives allow for lower compression ratios. Add a second hard drive so that that can be used for audio and then develop a windows based NLE software package for the PAR. What do you think? I see this as the proper evolution of the DPS PAR beginnings. I base this not just on the PAR design but also on the company's progressive approach to the video industry, just like Newtek.
#97543From: John EllisApr 17, 1994 7:28 PM
>> What I would wish for is to just let the faster IDE drives allow for lower compression ratios. << I've thought about this too, and it seems to me that if throughputs of 15 Mb per second are possible, this should enable lossless compression as that's only 2 to 1 roughly. I think you can go to 4 to 1 before there's some minutely discernable loss. So it seems to me that you should be able to get lossless compression and still have a decent amount of hard disk space. If it comes to a trade off I would rather have the higher quality as well. -JE
#97620From: Don LandisApr 18, 1994 12:55 PM
I don't think we're stuck with a choice in the PAR. With BLF settings we can just pick what we need, space or quality. Need both, get a larger drive.

>> I don't think we're stuck with a choice in the PAR. With BLF settings we can just pick what we need, space or quality. Need both, get a larger drive. I'm not sure that's true Don, because as yet no one has stated that the software will allow 1:1 and I wouldn't assume that by raising the BLF that you could attain lossless compression. I would welcome any evidence that supports your position but as the compression scheme has been held in confidence this has not been substantiated. -JE
#97352From: James J. BeyerApr 15, 1994 5:56 PM
John, Thanks for your imput also, as I told the other John, it's time for cocktails. Work will always be here waiting after I'm well rested from this week. One last question, who would be the apporpriate source to get printed material from, Matrox direct or my dealer (who didn't even know what the MAX was)? Thanks, Jimbo BTW Where are you located?
#97359From: John EllisApr 15, 1994 6:20 PM
James, I'm in San Diego, you? I would work with one of the dealers here. Angelo or Jim would be my recommendation for queries on the MAX. I am very confidant about Angelo and John T. has had good experiences with Jim. So take your pick. <g> Matrox will send you literature but these guys will be able to give you the nuts and bolts on what's involved. -JE
#97391From: Don LandisApr 15, 1994 11:31 PM
Jim: Interesting comments regarding the PAR vs. MAX (vaporware). I don't hear of anyone using it yet for high end output. Seems pointless to recommend it at this time. There is only one choice in my opinion for those with big bucks to spend on the high end and that's the Abekas. Otherwise it's the PAR, hands down. Yesterday, I saw my "Go For the Gold" animation theme logo play on the big screen of 20 ft. before an audience of VIP's and invited guests, about 3000 in attendance. I received many complements. One of the people there asked what I use to record my animation. I told him it was a DDR and he said, " We have an Abekas too!." I just smiled. As for rotoscoping, if I'm very careful as to the source video quality and the length of the grab I can achieve near lossless quality, but it is much trickier than recording animation. Sometimes I just can't get the video without noticeable loss (artifacts). John: Have you been hearing about the new IDE drives to be introduced later this year? Supposed to achieve 15+ MB/sec. sustained. I am beginning to think DPS' decision to go IDE was pretty intuitive since that seems to be where the greatest development gains are right now for speed and capacity. Since the PAR software can do higher BLF's we only need to wait for these new drives to achieve the higher quality.
#97398From: John TissavaryApr 16, 1994 12:10 AM
>>There is only one choice in my opinion for those with big bucks to spend on the high end and that's the Abekas<< Acutally, there are quite a few choices out there. Besides the Abekas, there are two units by Accom that are very nice. One is rackmount with keyboard edit controller just like the Abekas, the other is a desktop version that has its own box like a mac or pc, and has a little keyboard for edit type commands. They are both totally Abekas compatible, and cost @ $15K list. HP and Sierra Designs have new Digital Disk Array mainframes out, that will hold humunguous amounts of uncompressed D1, like up to 30 minutes or something wild like that. They both _start_ @ $35K. BTW, I've seen the MAX, played with it, love it, and will probably get one. It should be shipping soon (month or two?), although you're right – now it's noting but vaporware <g>.

>> Have you been hearing about the new IDE drives … << You know Don for once in a long time, I really really agree with you! <g> Yes I've noticed the advances in IDE and they do seem more stable than SCSI. This may be totally subjective, but I have been a strong proponent of SCSI's especially since the release of SCSI II but I'll tell you I'm very impressed with the Micropolis. But to tell you what I've also been hearing is that they are going to be introducing really fast SCSI II's also. The technology is not so different. None the less I will be glad to have the faster IDE and the improved picture quality. One thing I've noticed about you, and this is not an attack, but you get convictions about things, and it seems to me to the exclusion of other options. I'm not as convinced that the PAR is the answer or an Abekas. I see plenty of room for the MAX. Its not vaporware. I've said many times that I'm very happy with the PAR, but should the occasion warrant I wouldn't hesitate to get the MAX if it was available and I needed its capabilities. Ironically I think the PAR is better suited to the work I do and the MAX is better suited to the work you do. But that's just my opinion. -JE
#97500From: Don LandisApr 17, 1994 9:26 AM
Well, I like SCSI II too and the "industrial" quality one generally gets but I do see faster advances in the ide line. I wonder if the IDE is the drive force in the technology developments and the SCSI is just catching the benefits of the developing technology at this time. You're right about the convictions, It took me almost 9 months to develop my current attitude about the PAR, or should I say PAR technology including the MAX, Bandit etc. but now that it's here I am convinced it's right for me. My paying customers like the quality I can give them with it. I disagree with you about the MAX. I feel it accomplishes about the same thing as the PAR with far more complicated setup, greater cost, and only a little bit (purported) better quality. Since the real noticeable artifacts tend to show up in the real time frame grabbing of live video, I would like to see that quality on the MAX. When I did see the MAX in operation it wasn't then capable of more than 15 seconds of animation, much less frame grabbing. I'm sure the MAX has come a long way since December. But, it's still a complicated setup for my comfort.
#97544From: John EllisApr 17, 1994 7:28 PM
>> but I do see faster advances in the ide line. << Yeah, I'm not sure why that is or its just a perspective thing. Traditionally SCSI's have had larger capacity and IDE's played catch up, now it seems the technology is evenly matched, but there is more about IDE technology in the trades. Like you, at least the ones I read. I think in fact the technologies are not so different and that the same advances being made in IDE are concurrently happening with SCSI but there does seem to be more emphasis on IDE and multi-media. >> I disagree with you about the MAX. I feel it accomplishes about the same thing as the PAR with far more complicated setup, greater cost, and only a little bit (purported) better quality. << I think for your setup, this may be true. But you are discounting the fact that many people will want a 720×486 framebuffer because of applications like Inscriber, and higher level paint packages, and so are going to want a cost effective framebuffer, which the Ill Pro is relative to the Targa 2000 or the VistaPro. Also the fact that they will be able to do video editing and transitions with the Ill Pro, not to mention non-linear editing and so on. From that perspective, the MAX itself is relatively the same cost as the PAR. And as you mentioned Newtek, the Matrox combination is going much more along those lines than anything yet relating to the PAR. I would like to see all the things you mentioned for the PAR happen. Although I do not have a great need, if a need at all. Audio is left to audio specialists with my work, as is the editing. But it would be nice to have. I'm not sure where I'm ultimately going, because I'm reluctant to get into the video production side as it will take away alot more time from animation which I would rather specialize in. I also don't want Video houses to think of me as competition, so I've stayed away from that side. The benefit has been, I haven't spent all that money on video equipment, and can concentrate on spending it on animation related software and hardware. Which is why the PAR has worked out well for me I think. But on the other hand, the Matrox Studio if one was to get into the video side provides a totally integrated editing environment, which can also take care of Animation in real-time. It also has the nice DVE features and TBC's etc. When looked at from this perspective one can't say the MAX is over priced, and it certainly isn't any more complicated than the setup you have, I don't think. I could go on but I think you get my point. Actually somebody else should be making these points, I'm just an innocent by-stander. <G> -JE
#97621From: Don LandisApr 18, 1994 12:55 PM
All this stuff is true but I don't want to build an edit suite around the Illuminator PRO. I guess I'm still old fashion when it comes to video editing and I like the video boxes approach and linear editing. The reason for this is that almost all my editing requires numerous library stock footage mixing with current shoots. NLE systems are just not efficient in this environment. This is due to the time required to digitize and log the library stuff. I am in the market for a good switcher/DVE/controller now for A/B roll and have considered the Video Machine or the new Sony FXE-100. The other side of the coin is it would be nice to have NLE when those type of projects arise.
#97627From: John EllisApr 18, 1994 1:54 PM
Don, As the Matrox Studio currently stands it is an A/B/C roll system in its current configuration with development of a NLE in the works. You would have the option and when you consider the integrated approach of the Studio, your Illuminator Pro becomes more than just a framebuffer, but also a switcher, DVE, and real-time animation playback device. I thought Gus was disappointed with the Fast Video Machine in that it was a totally closed system and he couldn't get support for it? -JE

Do I understand that you did this on the PAR? If so, that's really impressive for the PAR. BTW, what does DDR stand for? Digital D?????? Recorder? Thanks, Dennis
#97502From: Don LandisApr 17, 1994 9:26 AM
Yes, I did the output field rendered to my hard drive and then transfered to the PAR at BLF 260, QF 23. The animation was recorded to the UVW-1800 via CAV signal from the PAR. It was edited to a master on a second UVW-1800 using a Toaster 4000 switcher and the master was safety dubbed for the performance also on the UVW-1800. Of course the video lost CAV quality once it hit the Toaster but at least I had the front end as strong as I could get it. DDR is Digital Disk Recorder, a generic term used to reference the Abekas A-66 and similar technology. I refer to my PAR as a DDR occasionally as a private joke. <g>
#97343From: John TissavaryApr 15, 1994 5:13 PM
For rotoscoping with the PAR you will need the optional TBCIV, which raises the price somewhat, I think with 1gig HD it's around $5K. You will then be capturing a motion stream that can be converted to .tgas to do with as you wish. The MAX should be out in approx. one or two months, and will cost between $6-7K, including Illuminator Pro framebuffer, but not including HD or fast SCSI II controller. It will also do rotoscoping out of the box, but you'll have to get a CAV add-on for the Illuminator Pro if you don't already have one in order to do Beta SP or other component in-out.

Hey, thanks for your feed back. It's Friday PM, I'm tired of thinking about this stuff, and it's time for a few cocktails to wash down the brain cells that were burnt up this week trying to configure the "best" system to add on. Jimbo
#97452From: Jim PopeApr 16, 1994 2:10 PM
OOPS – right to many PRO's around here Illuminator Pro. I have to get a new brain one of these days. Thanks for the support out there, I try. I just got your EMAIL, I'll get back to you on monday. My MAX is inhouse. The orders I have placed will be filled by end of April. So It's real in my book. As for the term "posturing" sorry, bad terminology, I really do see a place for both systems. One's "personal" one's "pro" regards- Jim Pope
