The resulting video is much improved. If you watch the video below, you'll notice almost no flicker or shutter.
It was windy on the roof, but I used the stabilization feature in iMovie to reduce the wobble from the wind buffeting the tripod. In one frame, you can see the camera's strap blow briefly into the picture. A 50mm on a DSLR results in a focal length of 75mm, so this shoot has much more zoom than the prior video. The prime lens is also a much higher quality piece of glass so that also helps with the image quality.
I'm happier with this result. Sadly, there was no bulldog puppy.
For reference, the original video is included below:
