The pocket openings for pool tables are measured between opposing cushion noses where the direction changes into the pocket (from pointed lip to pointed lip). This is called mouth.
Corner Pocket Mouth: between 4.5 [11.43 cm] and 4.625 inches [11.75 cm]
Side Pocket Mouth: between 5 [12.7 cm] and 5.125 inches [13.0175 cm]
*The mouth of the side pocket is traditionally ½ inch [1.27 cm] wider than
the mouth of the corner pocket.
Under BCA and APA Rules, the regulation pool table sizes are 9 foot, 8 foot, and oversize 8 foot.
Until fairly recently, a regulation size pool table was the 9 foot table which has a 100 inch by 50 inch playing surface. The 8 foot table was added to regulation size as well, and has a playing surface of 88 inches by 44 inches.
Regulation pool table sizes are termed 9 foot, 8 foot, and oversize 8 foot. There are also 7 foot pool tables that are very common in bars and pubs. All pocket sizes are the same regardless of pool table size. For this reason, a win on the break is more common on a 7 foot table than on a 9 foot table, if done by the same player. The pocket widths are 4 7/8 x 5 1/8 for the corner and 5 3/8 to 5 5/8 for the side.
Regulation pool table pockets are the same size whether for an 8 foot or 9 foot table. These are also the same size on a 7 foot table. The pockets are measured both at the mouth and the throat, and are different for sides and corners. There are other measurements needed, but these are the important ones for most people -
Corner pockets - mouth 4 7/8 inch minimum, 5 1/8 inch maximum
Corner pockets - throat 4 inch minimum, 4 1/4 inch maximum
Side pockets - mouth 5 3/8 inch minimum, 5 5/8 inch maximum
Side pockets - throat 4 3/8 inch minimum, 4 7/8 inch maximum
Under BCA Rules, corner pockets are 5 inches, side pockets are 5 1/2 inches, both are plus or minus 1/8 inch.
Under Billiard Congress of America Rules the corner pockets are required to have a 5 inch opening, plus or minus 1/8 inch, and side pockets must be 5 1/2 inches, plus or minus 1/8 inch.
Under BCA Rules, only the following pocket sizes are legal -
Corner Pockets - Mouth 4 7/8 to 5 1/8 inches; throat 4 to 4 1/4 inches
Side pockets - Mouth 5 3/8 to 5 5/8 inches; throat 4 3/8 to 4 7/8 inches
The smallest pool tables made that generally conform to regulation pool tables is the 6 foot table. This is often referred to as a junior size. Smaller sizes are generally toys, and larger sizes are in regular use, from 7 foot to 10 foot.

Pocket billiards ("pool") tables have pockets. Carom billiards tables do not. Apparently the table in the video is a carom billiards table. Whether this was a specific choice or whether it just happened to be handy I don't know.
Pocket billiards is very often called pool. The reason is simple...back in the day, circa turn of the century, rooms for betting on the horses were extremely prevalent. The horse betting pools were such that these rooms were called pool rooms for short. Because pocket billiards became so popular with men of the day, pocket billiards tables were installed in most of these "horse betting pool" rooms. Rapidly.."pool room" became known as a room with pocket billiard tables in it, and the pocket billiard game itself took on the misnomer.."pool".

There are no pool tables that actually measure 4 foot by 8 foot. This appears to be a child's math question rather than a pool table question. The playable surface of an 8x4 pool table measures 88 inches by 44 inches. The back edge of the pocket is not a critical measurement on the table. There is no "top pocket". So, the distance from the farthest outside edge of the foot (the top) right pocket to the farthest outside edge of the bottom (the head) right pocket is 88 inches.
