Hi Jack,

Attached is my project file.

The problem isn't the different size of the video frame, it's the
different aspect ratio. The sides are cropped off.

It's easiest to handle by using two lens profiles in PTGui. If I just
drop all your images onto PTGui, it already does this automatically:

- New project (PTGui Pro 12)
- Drop all your images
- PTGui asks for the camera sensor size: choose full frame (1x)
- PTGui asks for the lens type of the video frame: 12mm, choose the
Samyang preset
- PTGui again asks for the lens type, this time for the othe images.
Repeat the above
- Click Align Images

and basically that's it.

If you check the Lens Settings tab, you'll see there are two lens
profiles, one is applied to the video frame, the other is for the
remaining images.
