The Video Toaster/Flyer is a cool retro video editing system. It's one of the best the Amiga had but is NTSC only so Europeans didn't get to experance the fun. It also has a 4 input hardware switcher which is something software only editing soluutions don't have.
For those that experanced it, it was ahead of its time and easy to learn and use. If you set one up today you can just use solid state drives so no more hard drive madness. In the modern HD world that's quickly moving to 4K it would not be your daily editing system. Out of respect I would never call it a door stop. It's a great tool for what it does and the era it comes from. The software/hardware has not been updated in almost 20 years.
You can always buy a modern version of the Video Toaster, it's called a TriCaster and has none of the limitations people complained about in this thread about the original.
