okay 🙂
1.
you can easily import quicktime as material, not sure is you can use image sequences (for me foto-jpg codec works nice for playback)
2.
in the animation tab you can set the framerate and lenght to get perfect fitting.
2a.
for the camera move, if its simple you can try to recreate the original move with keyframes. if not, matchmoving software like syntheyes, boujou, or pf track are able to perform that, but they are most time expensive and complicated.
3.
for exporting use image sequences or quicktime , on window maybe avi make sense, but i am not experienced with avi.
hope that helps.
