I have a 15 png images (faces) created from a master image in Photoshop (the master contains all 15 face images, the 15 sub images have been created by removing face images from the master). I want to make an intro sequence using these 15 sub images, the video rebuilding the master image one face at a time, I have opted to shrink them in PD21 to ensure they fit in the safe TV zone. However I have been unable to find a precise way of doing this, invariably one of two images are "wrong" sized and the final effect is jerky.
The original master is complicated and I don't think masking will be possible. Any suggestions on how to precisely resize in 15 png images in PD21.
