We are given the dates but not the times and from what he is filming my guess would be a planet.
I suggest anyone interested visit this site: http://www.griffithmedia.org/skyreport/
"This is the Griffith Observatory Sky Report for the two-week period through December 5th, 2019. Here’s what’s happening in the skies of southern California.
"The brightest planet, Venus, as well as the second brightest planet, Jupiter, and third brightest, Saturn, are visible in the southwest after sunset in a formation that changes from night to night. On the 28th, Venus is the planet that is closest to the horizon. Jupiter is then to the upper left of Venus. Saturn is in line with the brighter planets, to their upper left. Night by night, Jupiter and Venus will appear closer together, until the 24th. On that night the planets are at conjunction, or aligned north and south of each other with respect to the North Star. Venus will be south (to the lower-left) of Jupiter and 1½ degree (an angle equal to three full moons placed side-by side) from each other. After that, Jupiter will be lowest of the three planets. In another couple of weeks, Jupiter will be lost from view in the sun’s glare. In the mean time, Saturn and Venus will appear to draw closer together."
