Searching for application

Hello,
I want to make slide shows of digital photos with effects like different
blending styles, fading in and out,  free programmable Zooms, an separate
audio track with exact editable synchronisation of audio and slides (which
blending at which exact point of the sound file).

One thing I dont even know if it exists: To make "virtual camera slides"
over the surface of a large image file: On the screen a lets say 12
Megapixel file is huge: So it would be possible to let the zoom move
over the surface of the photo, as if it was a camera. Understand what I
mean?

IF there is one application for all that, I would be happy - at least if its
not thousands of bucks..

thanks in advance for any input,

Bernie
