The video from the CNN report raises a lot of questions if you start to analyze it in detail.
As a result, it seems that frames from different time periods were taken and mixed with each other.

There are two versions of CNN's coverage of the event: on the CNN website and on YouTube.
For scene timing, I will use the one posted on YouTube, as there is a more convenient player, in my opinion.

Video
00:40 The shadows in the very beginning of the scene are in front of people
00:45 In the shooting scene, the shadows are already shifted to the left of the people, at a noticeable angle. But the CNN report gives the impression that only a few seconds elapsed between these two scenes.



01:18 A suspicious white civilian car with the inscription "Tank Special Forces V RUS". According to a Russian military expert: 1) the Russian Federation doesn't have such a unit; 2) none of the military would let such a transport through; 3) it is extremely dangerous to drive such vehicles in a war zone, as there is a great vulnerability to any type of small arms.



01:57 In the upper frame, a yellow car is visible standing outside the gate, but in the lower frames (supposedly filmed at the same moment), this car is not visible.



Many of the shots have the date cut off. On a few scenes the dates are visible, but they change from Friday to Saturday and from Saturday to Friday. The frame with the word "FRI" (Friday) is not fully visible in the Youtube footage, but it is on the CNN home site, watch the video from 2 minutes 19 seconds.



More information is in the detailed analysis of this video in English.

Also, in early May 2022, the NYPost published an article providing additional food for thought: "Biden’s new press secretary sparks conflict-of-interest concerns over relationship with CNN’s Suzanne Malveaux".
