More tips for mpg. Form testing on fairly ancient machines
use mpg at 352 x 288 as this is the standard windows mpg1 format, every other size was prone to tearing/artifacts under test data rate about 1800 ish (cant remember the units but your compressor will be similar I expect) whatever size your video is eg 640x480 or whatever, compress to 352x288 then scale that back to 640x480 and you get NO change in aspec ratio (you can only use this trick with director :-) ) Makes it very easy when your video arrives as 400x400 HTH Dave ----- Original Message ----- From: "Brad Hile" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, January 09, 2003 4:45 PM Subject: RE: <lingo-l> Digital Video Question > Paul Steven wrote: > > Simply question hopefully!
