It looks like the cannons were fired during the ride to the Tomb Of The Unknown soldier... is this video spliced edited ? or do they have two cameras and switch to the motorcade visual while keeping the sound from the salute ?
strange...
Only 3 guns. Only 2 are firing. Video is not long enough to tell how many shots...

Timing interval between shots...
According to AR 600-25, Chapter 3-3 the cadence for a cannon salute is as follows:
(6)b. Cannon salutes to persons.
(1) The time interval between rounds in a cannon salute will be three seconds except as follows:
(a) When honors are rendered at funerals, in which case the cannon salute will be fired at five second intervals.
...
(2) The firing of a salute will begin at the time the person entitled to it enters the installation.
However, as noted in the Arlington National Cemetery Blog: https://www.arlingtoncemetery.mil/Blog/Post/12870/Presidential-Salute-Battery-Honors-Dignitaries-and-Events
“For a visit from a dignitary such as President Lasso (President of Ecuador), a communications representative in the lead vehicle radios Capt. Nathan Lundquist, the battery officer in charge, as the vehicle passes by McClellan Gate. That starts the firing sequence. “We found through trial and error,” explained Lundquist, “that nine seconds is the interval spacing that gets the last round fired as they get to the Tomb.””
Final note - interestingly enough, the Soldiers who man the Presidential Salute Battery are not 13B - Cannon Crewmember, they are 11C - Indirect Fire Infantryman - in other words, Mortar Gunners.
