Looking for a good app that converts sequence of images onto animation

[Anakunda]

HI!
I'm curious if there's such an application able to load a sequence of static pictures and turn them to a video or animation, then able to make necessary transformations like resizing or changing color depth, and finally export eighter as video or animated .GIF.
I have tried several applications that I already have installed like Fireworks, Vegas or Corel VideoStudio but none of them seem to handle that job. Anybody can recommend a good app specifically aimed to this? Of course if there's no such, more applications that could consequently do the partial tasks would be accepted as solution too.
Thanks for any recommendations

You load each image into a layer and after any adjustments Export as gif.

Yep, I already found it.
File -> Open as layers... and File -> Export... -> Gif animation
