Yeah! They’ve got a pretty easy 3d tracker built in. Not as robust as Blender’s but for fairly straightforward shots, it’ll do!
And oh yeah- I filmed the water for real. All of the digital water I rendered out was just a kinda rough glossy plane, which looked pretty bad (though not as bad as I thought it should look?), so I tried to make sure there were always some real lights/reflections near the horizon to help sell it.
