We just received our copy of QTW on the 10th (yesterday). Each of the codecs is implemented in a DLL with derivative names like qtrpza.dll for the standard road pizza video compressor. I made the mistake of trying to play a compact video compressed movie under windows. No go. That's when I started checking out the dlls. Should be a simple matter for Apple to add a new DLL to the list as new compressors come out (where's that Compact compressor?). > as far as performance goes, i got 'okay' performance out of the system as I > have it set up currently, with very few optimizations...

I've had the opportunity to test out performance on a IBM model 95 with XGA/I and maudio. At first I thought Quiktime didn't like maudio, but it was the XGA running (640x480x256) it was complaining about. We really must upgrade to XGA/2. Otherwise, QTW runs fine on a ps/1 486DX with an ASI Winjet card, and a Soundblaster Pro card bundled with an optimized CD player from Creative Labs Inc. I haven't benchmarked this set up to any great extent, but performance feels similar to a Mac IIfx running QT1.0. Sound synching did seem a bit off though. > > Also, QTW does *not* support recording at this point... hell, they haven't > even given us an MCI command set (a real bummer for those of us trying to use > the thing in MM Authoring packages... looks like i get to learn how to compile > in MS C/C++ 7 this month, eh? :>) What you really notice when running QTW, is the different window sizes. You're not restricted to a window size of 160x120 as in V4W. At this point, you get a QT Windows player (like XING's MPEG player) and a few nifty utilities like a fli/flc-to-movie converter, but QTW is being distributed with an API, so what you don't like.... > Reviewer's Rating: give it some time...

Maybe at the same point, but I find it very enticing that I can now fully exploit the superior suite of desktop video editing tools available on the Mac such as Videoshop and Premiere *AND* be able to share my QT movies with DOS box MM apps. cheers, b. P.S. Does anyone know anything about the AVSS-to-movie converter that was mentioned in the readme on the CD; I can't find this anywhere? ----------------- Blair Rosser, rosser@sfu.ca Excite Centre, Faculty of Ed., Simon Fraser University Burnaby, B.C., Canada
