I see you are from California---are you sure its not just an earthquake???

I have been balancing engines for over 30 years .

Is your car a stick or automatic?
How do you know it was your engine in the video?
Are your pulleys custom built or are there others like them?
Was your engine balanced/dynoed with the flywheel/flexplate that you have or was a change made to different one before install(((((many,many times, an externally balanced engine changes owners or planned vehicle install and the flywheel/flexplate will get changed for a different clutch /trans type))))))probably see that as much as 5% of the time
If flexplate, is it installed backwards???? clocked correctly on flywheel? takes some effort but by filing out boltholes can be done?
If it is a stick, and you have an aftermarket flywheel there should be a bolt on weight on the front side of the flywheel that will be opposite of the front balancer weight---if it has the weight---and is not opposite the front exactly, the flywheel is on wrong or the front balancer was put on without a key and has turned---
Is the front balancer an oem stock ford or an aftermarket one??????don't say fluiddamper

On the flywheel weight----if it is missing but you can see the bolt holes wwhere it goes, you can add the weight and see if that works or changed the weight to a different amount

if you can verify that changing weight on the flywheel changes the amount of shake---you can probably fix it by adding the right amount or if its a flexplate by changing to the correct one.

As for it being a miss----since 1958--- many missing/rough running fords had 3 plug wires installed incorrectly on the left bank---checking them would be the first thing I would do and the second would be verifying that the front balancer was on correctly by doing a tdc check
