Using 1 x layer as animated background - cloud loop (feedback video - 006 SD_Cloud010.mov)
+ 1 x layer as tiff object with either embedded invisible background (see attached) or invtint on the white background (depending upon picture) - object then moved from L to R of screen with x,y posn
(ie a shoe flying through the clouds!)
Noticed a slow down of the background as the 'shoe' moved across the screen - normal playback resumed as soon as the shoe disappeared
Using a G5 2G mac with 2GRam - clean up-to-date hired machine - think it was a SATA drive, but might have been a fast SCSI one (wasn't my G4! - I only use it for pre-production)
Incidentally - are there any issues concerning xfade between a PAL and NTSC clips? Is it recommended to stick to one format - or doesn't it matter?
