Re: FLASH: OT: Exporting in QT?

[Michael Penne]

We just digitized a 20min video at video codec, 

15fps, 320x240, about 4 gigs with sound, so your file

size is about right(video pros generally use dedicated

multi-gig->terrbyte raid arrays for editing). For

vector graphics, the animation codec is better. For

playback on a computer, cinepak, sorenson, or indeo is

a better option(however, while you are editing the

video, use the animation/video codec). 


QT skips frames when your computer can't keep up with

the data rate of the video file, so yes your file is

too much for your computer--> it may be more of a disk

issue (assuming you have ~200+PPC+lots of ram), QT

needs to read the file off of your disk, and for video

codec playback you want a disk/bus that can transfer

data at a sustained data rate of~20mb/sec-at least (ie

ultra-wide scsi or firewire, the stock disk/bus on

most macs does 5-10mb/sec, while the ata drives on

newer macs and pcs have trouble with sustaining high

data rates, beware of buying a cheaper drive as many

mftrs. market a data rate that records maximum burst

transfer rather than sustained). Adaptec's 2940uw is a

scsi card one that many mac-vidheds praise, though I

recommend moving to firewire;-)...
