Andrew, I am both a long time reader and a Barcelona resident.  Do no hesitate to contact me if you need anything. 

There is a bit of overlap in terminology, so It's confusing.  By "triple exposure video," I think that OP intended to mean "HDR video with three different exposure levels."
 
Historically, the terms "double exposure" and "multiple exposure" meant exposing a single piece of emulsion in-camera, two or more times, to combine different images into something like this:

 
With digital imaging, the multiple exposure process is a little different, because each exposure is a separate image and, thus, a separate file.  Some digital cameras offer various ways to combine files and to create multiple exposure images, such as the Canon 5D mkIII and the Olympus OMD cameras.
 
Undoubtedly, most who create "multiple exposure" images today are combining the images in post/editing.
 
 
Magic Lantern offers two HDR video methods:  Dual ISO (which you mentioned) and HDR video.  I don't remember which method appeared first.
 
ML's Dual ISO is a technique in which every other row of pixels is given a different exposure/gain.  So, for example, all "even" rows are given a darker exposure while all "odd" rows are given a brighter exposure.  The separate exposures are "blended" to make a single HDR image.  This method can induce aliasing/moire.
 
Our own @ZEEK made a video tutorial on setting up a Dual ISO raw video on a Canon EOSM:
 
Incidentally, "dual ISO" has morphed into a term for more recent cameras featuring a sensor that can be "set" to one of two native ISOs.
 
On the other hand, ML's HDR video simply gives a different exposure/gain to every other frame.  For instance, every "odd" frame is given a darker exposure while every "even" frame is given a brighter exposure.  This technique doesn't suffer the aliasing/moire of ML's Dual ISO, but I seem to recall reports of motion artifacts.
 
By the way, prior to ML's Dual ISO, Panavision touted their Dyanmax HDR sensor which was claimed to feature three different, nested pixel arrays, with each array having a different exposure (somewhat similar to ML Dual ISO).  Panavision has remained mysterious in regards to why they abandoned the idea (and subsequently sold their sensor foundry).
 
 
It was done in 2010 with two Canon 5D mkII's and a beam splitter (probably the mirror type):
 
 
Here is another early method from 2011 with a single Canon 7D and a post process:
 
 
For three cameras, one could possibly use a prism beam splitter.  If one could put the beam splitter and three shallow-mount cameras in a light-tight enclosure, it might be possible to use a single "taking" lens.

It's a technique of combining a darker exposure and a lighter exposure in order to have a bigger dynamic range to work with. 

sorry, I don't understand, what do you guys mean by "triple exposure video"...? how would that work, and for what purpose...?
I'm dumb lol

Andrew, are flights to Berlin possible? Renting a car and driving to Berlin would be very exhausting, but maybe an option, if available. Are you staying with friends in Barcelona? Stay safe!
It is very true, this competitive rat race is not healthy, now this Virus on top of it. I hope everyone enjoys this community very much just like I do. I read here often, when I´m happy or sad, to share cheerfulness and the beautiful lens and tech nerdom and peacefulness of nerdom. We owe one another in this world respect and appreciation and support, so do we towards one another in this forum and to you, dear Andrew.
Thank you very much. And let us know, how we can help.

Crazy times!
Boarders being closed, countries and cities being in lockdown, who could´ve expected this when this year started?!
Here are some impressions from Munich, near the train station. Usually really crowded, almost at any time of the day. These days, people doing home office don´t have to commute to their workplace, staying at home anyway. Unfortunately in the afternoon some places here get quite crowded with people meeting to chat, to drink or eat something together. So a lockdown for the city of munich has already been discussed.
 

Last month I made a trip to Barcelona to film the Formula One circus in town for the pre-season test. This, it turned out would be the last time the 2020 F1 cars would run. When a McLaren team member tested positive for the virus at the first race in Australia, the race was called off. In a twist of fate I met McLaren CEO and team boss Zak Brown in track grandstand and watched the new car in action before crisis hit - now we might never know how fast the car was versus the likes of dominant Mercedes and Ferrari.

I've always said that absurd partisan argument is a luxury of good times in the US
these are bad times. let's stick together, ok...? 😎💙👍

In all seriousness I fully support the restrictions and I'm annoyed at myself for not knowing about today's addition to it.
Particularly as this lunatic has now reset my own danger of exposure clock again when it was only a few days from running out by screaming in my face.
The rage and hatred he had for me was incredible though as usually people only reach that point with me when we've been formally introduced at least
Oh well, he'll have plenty of justification when true boredom sets in on day 13 and I fly my drone off the roof to pick up stray dog turds off the golf course and drop them all over his garden.

So.....
About the original point of this thread then.
Has anyone got up to anything interesting yet whilst in isolation that they can share with the group?
Yesterday I posted this live scene from my workbench and I'm pleased to share with you all the outcome of what was going on in it.

With having that ability to concentrate fully on a project that only fully being in isolation can bring, I have completed eating both bars of chocolate.

Sony had a setback in the trial of theirs when Doctors mistakenly thought patients were getting sicker due to the green tint it gave their skin colour.
 

Of course, Sony's version of the Corona virus drug was supposed to come out last year. I am sure it will be released any day now...

A silver lining about the coronavirus: I'm working on an advert for it today (and tomorrow)

no kidding! do you eat shoes?

You're too demanding, girl! :- D

A lucky bastard! : P
 

I also have a fluffy butt.

all the more reason to be patient

my st bernard puppy bruno has a fluffy butt shhhhh

I must add that I think his ideas are misrepresented and as a whole, my life has changed very little since Trump became POTUS. In fact, monetarily, prior to present events, my wallet has been the best it's been in 13 years. 

President Trump isn't an idiot, far from it, he's an egomaniac. Hopefully, this event will alter his behavior a little, and as a country, we can get away from this identity politics bullshit during his second term.

Not in lock down YET but since my flat is 12 steps from one end to the other (I get another couple by turning left into the bathroom), my main plan is to just go crazy!
