I didn't see it here, so I'll post it, courtesy of a site with simply awesome information on the guillotine and a pictorial history.
Scroll down to the bottom of this page for the clip. History of the Guillotine
A new incredible filmed document has surfaced in the last 5 years, documenting the guillotine execution of two men. The people who made the film public have asserted that it is the 1933 execution of Veteau and Martin, by Anatole Deibler, in the city of Angouleme. The film is of poor quality but an incredible document from a historical standpoint. As I viewed it, I came to the immediate realization that it could not be the execution it claims to be. The first issue is the type of the equipment used. The jerky pictures, grainy quality, wildly varying speed and exposure from frame to frame points to a hand-cranked camera of pre-1920 vintage not what would typically be used in 1933. The opening scene, pictured on the right, shows the guillotine in a brightly lit dirt venue in front of a prison gate. Deibler carefully notes in his "carnet" that Veteau and Martin were executed at 3:50AM on July 20th, in total darkness. The architecture of the prison, with the vertical slit wall openings, the arched gateway and the characteristic base stonework is near identical to the modern shot of the "Maison Centrale" in Tonkin (Hanoi) shown below. The first letter of the word "MAISON" can be discerned over the door inside the red circle. Click here for an older photo. The "Maison Centrale" later became known to captured US aviators as the "Hanoi Hilton". Other issues such as the clothing worn by the spectators and the unpaved city street do point to a colonial setting rather than to a 1933 French provincial town. The guillotine is definitely a real model 1872 Berger and there is little doubt about the authenticity of the footage itself. The following scene takes place right after the opening general scene above, before either of the two executions has been filmed. The camera has been moved closer and becomes completely stationary for the remainder of the sequence. This camera is obviously on a fixed tripod and not handheld by an amateur standing in the middle of a crowd of onlookers. There are no people between the movie camera and the guillotine. Considering the outrage caused by the filming of the Weidmann execution in 1939 (Done secretly from an apartment window) it is impossible to imagine how a professional cinematographer could have been allowed to set up a fixed camera, practically overhanging the zinc tub, in France in 1933... This is the kind of thing that could only happen in a colonial setting far away from the eyes of the French government. The scene shows an aide leaning into the basket and also the blade in the dropped position. In the red circle we can clearly see that the blade is bloody, which is inconsistent with the fact that this scene precedes the first of the "two" executions. Immediately following this scene a bucket of water is thrown on the bascule and blade, obviously to wash off the blood of the first victim (before the "first" execution). Noteworthy also are the facts that the ropes are not "stored" on the hooks as they would normally be but instead are draped over the back of the bucket and also that there is no shield around the tub (Possibly an arrangement between the photographer and the executioner?). Such "sloppiness" is not likely from Deibler's well-trained team of professionals. After this, the first condemned man is brought forward and as he is "tilted" on the bascule one of the aides whips open the basket and reveals what we already suspected, the foot of a corpse in the basket (in the red circle). This is the final confirmation that we are dealing with a triple, not a double execution. Other notable facts are that the condemned men wear no shoes and that the executioner's aides wear loose fitting canvas uniforms similar to what was worn at the Bagne in Guyana. My best guess is that the film clip is from 1915 to 1920 and shows a triple execution of "forcats" at the Maison Centrale in Tonkin, Northern province of French Indochina.
