The Korsac EM-1 (not to be confused with the Thorpe EM-1, which is a completely different rifle) was a bullpup light machine gun based on captured examples of the German FG-42 patatroop rifle. It was developed between 1945 and 1947 by a team led by Polish refugee designer named Korsac. It was chambered for the 8mm Mauser cartridge, and used an 18 round magazine adapted from the ZB-26. The operating mechanism was closely copied form the FG-42, as were many elements of the rifle's controls, including the capability for firing from an open bolt in fully automatic and from a closed bolt in semiautomatic. Unlike the FG-42, it used a short stroke tappet type gas piston, and had a detachable barrel. Ultimately only two examples were built, and only one of those (the one in this video) was completed to firing condition. It suffered from reliability problems in semiautomatic mode, and was quickly sidelined in favor of the other development projects ongoing by 1947. However, many lessons from its development would be put into the EM-2 rifle.

The EM-1 was one of the British post-WWII rifle development projects with the ambitious goal of replacing both the infantry rifle and the submachine gun with a single select-fire weapon optimized for combat within 600 meters (as opposed to the prior doctrine of 1000m effective ranges). The design team was led by a man named Stanley Thorpe, and the first rifle was ready for test firing in December 1949. Mechanically, the Thorpe EM1 used the same roller-locked operating system as the German Gerat 06 (note that it was locked, not roller-delayed). This would coupled with a long recoil gas pistol (the Gerat 06 had used a short stroke piston) and put into a bullpup configuration, chambered for the .280 British cartridge. Interestingly, it was also fitted with a mechanism which automatically dropped the bolt and chamebred a round upon the insertion of a loaded magazine. The basic operating mechanism has plenty of promise, but the implementation in this case was far too complex to have survived serious trials. As NATO trials rapidly approached in the early 1950s, it became clear that the UK could not submit both The Thorpe EM-1 and the Janson EM-2 for testing. The EM-2 was a simpler rifle and more likely to succeed, and so the EM-1 was dropped from development and all efforts concentrated on the EM-2.

The EM-2 was the rifle that the British pushed for NATO trials in 1950. It was a rifle well ahead of its time in several areas - as a select-fire bullpup rifle, it was intended to replace both the infantry rifle and the submachine gun. Its .280 caliber cartridge was designed with combat ranges of 600 yards and less, acknowledging the reality that engagements beyond even 300 yards were extremely rare, and not important enough to base rifle design on. It was also designed to use primarily optical sights, long before this concept would be embraced elsewhere.

Unfortunately, the potential of the EM-2 was lost to the political decision that compatibility with American ordnance choices was a more significant benefit than an improved infantry rifle. Mechanically, the EM-2 is heavily based on the German G43 flapper-locking system. It uses a long stroke gas piston in place of the G43's short stroke one, though. To help account for the slower handling of a bullpup configuration, the EM-2 would both lock open when its magazine was empty and also automatically close the bolt and chamber a round when a fresh magazine was inserted. The safety was much like that of the M1 Garand, and the selector lever was of the push-through type like on the German Sturmgewehr. The optic on the EM-2 is quite tiny, and offers no magnification. Its purpose is to reduce the two-element sight picture of traditional iron sights to a single plane that can be more quickly and easily placed on the target. In total, only 55 EM-2 rifles were manufactured, including the paratrooper model in this video and a number of 7.62mm NATO examples made as a last ditch effort to remain competitive in NATO trials. Where most failed prototype rifles were rejected for very legitimate technical shortcomings, the EM-2 is (I believe) a prime example of an outstanding weapon that fell victim to politics unrelated to its actually qualities.
