Hello, I currently have a 386 clone with a Soundblaster and SVGA. I wish to get into "hobbiest" multimedia - however, I am not so happy with the multimedia capability of my 386. I know I can upgrade the sound, but SVGA can't seem to do fast full-screen animation, and also, I want to go out to video tape, which I can't do right now, nor a few other things I mention later on. So I am looking to replace my 386 with antoher system. However, I am on a strictly limited budget. I don't need the highest quality, but I am limited to $3200 total, for the whole shebang. I have in mind two systems. One is Mac based, one is Amiga based. However, the dealers from these two places tell me contradictory things and I don't know which to believe (or maybe neither! :^) First of all, my minimum requirements are: 15 bit color, video resolution, the ability to easily get multimedia presentations out to video tape, good (24 FPS?) frame rate. I don't need 1024x768 graphics because I think video resolution is only about 350 to 400 scan lines anyway for SuperVHS. Also the $3200 hardware budget is *fixed*. I have some more to budget for software but that's another day's problem. Now, the Macintosh dealer is recommending a Mac system running Quicktime. The Amiga dealer is recommending an Amiga 3000 with some device called "DCTV" which he claims gives 18 bit color in video res animations. The Mac dealer says that the Macintosh has much more multimedia software graphics, animation, and sound available than the Amiga, which makes sense since it has a larger customer base. A good software base is an important factor in buying a system. So this would have me leaning more towards a Macintosh. However, the only thing that bothers me about the Macintosh is that the Quicktime movies I see all look jumpy and slow, and do not use the entire screen (just a several-inch window), whereas the Amiga animation with the DCTV seems much faster and uses the whole screen in video res. I ask the Mac dealer about this and he says that there are hardware devices to speed up the QT movies: - however, they all would push my price up to over $3200 which I simply *can't* do. So one question is: is it possible for me to get 18 bit full-screen 24 FPS video from a Mac with Quicktime and keep my purchase price for hardware under $3200 total? This must include a way to move the QT movies to video tape on my VCR. What device do I need for the Mac to do this, and how much does that device cost? What sort of Mac system is best for this? Do I need a Quadra, or can a Mac II do this level of animation with QT? The Amiga has only a 68030 so I doubt a Quadra (68040) is needed for 24 FPS fullscreen animation. Maybe a 40 Mhz 68030? Is there a Mac II with that, and how much $$ is it? Second, I want to have the ability to animate directly off of the harddisk in order to play animations larger than memory. Can Quicktime do this? There was some software the Amiga dealer had demoed which did an acceptable job at animating in DCTV mode from hard disk, but the demo only used about half the screen to move and the other half was just "static", sort of (ie, all one picture covered the whole screen, but only half of the picture contained any moving elements). Can QT animate double buffered from HD and if so, can it do it in full screen instead of the half screen like the Amiga program was doing (also while playing sounds)? (It was half, not quarter, since it was updating the bottom of the screen while the top was showing still sky). What I think this involves is to have two tasks, one which reads from HD and fills buffer, and the other plays the animation from that buffer. (It is abilities like this that I can't get on my 386, nor can I get acceptable frame rate animation from it unless the whole screen is not updated). Third: since the Mac dealer says that they have a much larger software base for graphics and video work than the Amiga has, how much should I expect to spend for good multimedia software? My software budget is about $500 total, right now, to get up and running, but I can add more software in a few months (maybe $250 more software in 3 months). Ideally I'd like: the quicktime program, a sound sample editor, a paint program, a ray trace or scan-line renderer for generating animations. What else do I need? Also the Ami dealer demoed a program called "Scenery Animator 2.0" which looked to be really cool and useful for some multimedia applications - this sw was only about $65. What are the comperable packages on the Macintosh, and how much do they cost? Also, should I give the Amiga any more consideration than I am giving it now? I have to admit that the DCTV animation *did* look much higher quality than the QT animations, but I am just worried about the lack of software and the small user base of that machine, since my friends all say it is a toy and not worth getting. (Although it didn't look like a toy to me, but I haven't used it much in order to really know - all I know is that it has a multitasking OS, but Mac System 7 has that too. I definately want multitasking in order to render while I do things like dial into BBSs, use word processor, or whatever, which is another reason I'm giving up my 386, because it doesn't permit me to do that very well even under Windows or OS2. I know the Amiga can do this well, because the dealer gave me a demo of running a ray tracer, running that Scenery Animator, downingloading at 9600 from a BBS all at the same time, and then using a WP in the foreground and everything worked very well - no dropped chars in the download, and two number-cruncher programs made good progress even while the WP responded quickly. I gather the Macintosh under System 7 can do this same sort of thing, but the dealer there didn't have a modem connected in order to demo that - my 386 cannot do this at all. Maybe a 486 could under OS/2, but I want to explore a new computer since I've had the 386 for so long. Oh, also, can the Mac play soundtracker modules? I like these, and have a good collection already for my 386. Can I use the exact same files to play on the Mac as I have now for my 386? I guess that's about all. Thanks for any info on this topic. I have a slight leaning towards the Mac right now, but I need more information and I don't trust the dealers very much. I suspect the net is much more knowledgable than the dealers are :-) Mark "no .sig" Dickerson.
