I saw this video before, the questions I have would be:
-does the opener still reverse if it contacts a 2*4 on the floor?
-could the door be lifted up to gain entry in a robbery?
-how to release the door for manual use?
-does the opener still reverse if it contacts a 2*4 on the floor?
-could the door be lifted up to gain entry in a robbery?
-how to release the door for manual use?

First question; I would have to guess yes. Like when a rail type install the opener is pushing the door down. So the same resistance sensors will in play.
Second and third questions;
I would have the same questions about the LM product.

The way he has his set up it will not reverse in the down cycle, like he said, up is down and down is up. That means it will only shut off in the down cycle. NOT GOOD! The last thing you want is the door reversing while it's opening. Also there is no manual operation for that set up. I think I'll pass!

Those were my thoughts - that it will stop and reverse while going down but it doesn’t (obviously) when it is going up. That would be a safety issue.
If you had it operating correctly - down for down, up for up - the only other thing I see is not being able to easily release it if the power goes out or if there are any other issues with the operator.

Why? The LM3800/8500 has an auto door lock and a manual pull release on the unit.

That set up is a liability waiting for a tragedy! Personally I wouldn't want to be responsible for the unthinkable.

True, if you have the side room to mount it which he obviously doesn't, plus mounting it on the left side, you loose access to the limit adjustments. If they need adjusting or you need access under the cover, you'll need to pull the whole unit.
Notice how he doesn't mention how long it took to figure out and hang that set up and it's still wrong. What's he trying to sell, a couple pieces of angle and an extra sprocket? Then you still have to figure out how to mount it. Not all horizontal tracks are the same.

If it was mounted on the left side, it could be mounted the proper direction and still have access to the limit switches. By mounting it on the right, he had to reverse the direction of the unit to have access to the limit switches.

That thing is a joke. Virtually every safety mechanism is eliminated. Jackshaft openers are really not meant to be used on standard lift track. The reason is that you can't push a door down with a cable. Gravity must act on the door to make it go down. With standard lift track, initially there isn't much vertical force to make the door go down. Now there are ways to mask this, like pitching the horizontal tracks and using pusher springs, but there is still the question of what happens if the door comes down on something. With the RJO at least, the cable tension monitor will detect slack in the cables and cause the operator to reverse. In a setup like this, there is nothing that will cause the opener to reverse (the internal force adjustments mean nothing because there is no change in force as the opener continues to turn the shaft). That means you end up with a wad of cables and a door sitting on whatever it isn't supposed to.
I don't normally throw this out, but the guy that posted the video is an absolute idiot. It is bad enough if he were just to do it for himself, but to make a video and try and sell this BS to others is just ridiculous.
Please no one follow this guy's instruction!!

DO NOT buy his ****. If you are going to to have something jerry rigged together, at least do it yourself.

Why not just spend a few extra bucks and get an opener designed for your application, install it per instructions sensors included. Now you never have to look over your shoulders and call it a night!

This guy has an earlier video (with irritating as hell music) in which he addresses many of the conversion issues. Then he has this video to follow it up:
Actually, the music is irritating as hell again. Guess I'm an old fart stuck in the Eagles era of real music.
The manual release could also be done with a long quick pin that you depress the center button to release the hold ball on the other side of the sprocket.
Since my new garage build may one day acquire the current Genie screwshaft door opener from my current attached garage I'll just buy a quiet new jackshaft style opener for the house garage.
