I resolved same issue, convertingAVI 3D video (Fuji are native in multistream format) in Wmv Side-by-Side video, perfectly managed by Pinnacle Studio. The APP to converte Fuji AVI multistream in WMV Side-by-Side  is MyFinePix Studio (free by Fujifil website)

Same Issue with Studio 18 last patch 

40 minutes project, 1920x1080, 50fps progressive. Footage is mixed: 300 photo from different cameras (Lumix superzoom, Nikon Reflex, Canon Reflex) and also videos from  different cameras: Lumix (1920x1080 50fps progressive); GOPRO (1920x1080 25fps progressive); something from Youtube (mixed quality). Computer is: QuadCore Intel Core ...

In my experience (in all Pinnacle Studio versions [15, 16, 17, until 18.0.2 32bit]) pan&zoom effect applied in automatic mode take a portion of the photo and move it (red point and green point are not in the same point). Instead, in Studio 18 64bit, the red point and the green point coincide....

Lino, have you checked if P&Z effect keep all your photos centered? If so,  it's an issue, because P&Z must zoom (OK)  and ''Pan'' (move from the centered view) the photo.

If I move the green point obviously it works and I can apply pan effect. The issue affects only ''automatic'' way. For Culparn: it's exactly what I say: in automatic mode (and Smartmovie  uses automatic Pan & Zoom) the only effect applied is Zoom (every photo remain centerd), the same on every photo.

My Studio 18 (both 32bit and 64bit) slow down when editing.  Beginning goes fast, then gradually slows. I have to quit and restart it to continue to edit my project.

18.0.2.444 (64bit)
