The coral in that vid is not healthy...and it's not because of those pods.
Amphipods eat corals is too generalistic.
Thousands of species of pods and thousands of species of corals!

I've seen corals eat pods

Hate to disagree with you Gary, but it looks to me like it's the amphipods doing the damage. That acan looks like it was doing well enough to encrust and then the amphipods started going to town.

I don't mind disagreeing

Many reefkeepers have thousands of gammarus amphipods in aquariums housing LPS.

Looks like the pods in that video are eating unhealthy coral flesh to me... and that's the same thing many other critters would do.
For example:
Angelfish and Butterflyfish tend to pick on unhealthy corals.

It is strange, and I'm not sure if it's certain species of amphipods (there are ~10,000), or starvation trigger, or what. It's definitely true that they eat unhealthy flesh as well.
I wouldn't have believed they attack healthy corals, except for my experiment I mentioned earlier in this thread. After recovering out of reach of the amphipods, I put the acan back on the sand and it started getting attacked again. Not as badly this time, and it survived long term.

Amphipods eating coral

Gary, the coral was perfectly healthy, they attacked and killed a healthy blasto, when it was gone they moved on to this acan. I'm not saying all amphipods eat coral, I am saying some do and people need to stop saying " what r u talking about, amphipods are good, coral must have been sick and dying" it's not always the case. I have moved corals to cups in same tank to watch them recover and then be attacked again when cup is removed. Based on what is the coral in the video not healthy?, I've had it for over 2 years.

So you have coral killing pods. Do they kill any other types of corals?

They don't bother my tongue, Duncan, suns, hammers, favia, they are picking at a open brain but it had a bit of a knick and is new to the tank. Think it's recovering. The Suns catch the pods and eat them. Pods bother the crap outa my stomatellas but don't seem to be able to do any harm. So no so far that is all. I'm still curious why you said the coral was sick? Is there something I am missing that you were able to determine from the pic because I'd love to learn.

Lol full circle, anyway the point I was making is that it is not always the case that a coral is sick when being preyed upon, I have witnessed it, the coral was perfectly happy. I had trouble with this coral, finding the right placement, then about 6 months ago I made the mistake of putting some peppermints in that almost killed it completely, since then it has encrusted and grown nicely like never before. I had a 6 line who decided to be a skydiver when i wasn't home, he had no parachute. I have considered a mandarine but don't know that it would sustain and am most likely going to go with another 6 or a yellow. To add I have recently significantly reduced my feeding so I am thinking that may have contributed to the attacks.
