If you want to do a Zapruder Film-like second-by-second breakdown of the shooting, pay special attention to the officer’s legs and feet. they show clearly when he is in front of the vehicle and when he is clear and to the side. Michael Sellers provides a very useful breakdown:

Renee Good Shooting: Three Shots, One Timeline: A Preliminary Forensic Video Breakdown.

America is on fire today after a stunning and tragic act of violence occurred. In the immediate aftermath, two alternate “realities” emerged — both of which cannot be true. According to the US Government, what happened was a weaponized car attempting to ram an ICE officer who fired defensively with justification. According to state officials, witnesses, and others — that’s not what happened at all—it was an unjustifed shooting of an American citizen who was not a valid target for lethal force.

I do video forensic analysis as part of my official work as an investigator. Tonight I have done a preliminary breakdown of the bystander video, much as I would do in the normal course of my work. This is preliminary — more time is needed to do a proper video forensic analysis of all the videos and what they may yield. But for this preliminary version, I have zoomed in, applied a timecode counter so we can precisely measure frames and seconds, provided various slow motion versions and have identified key frames and have frozen them.

I think the best way to review this is to first view the video, then read the written report with screenshots that follows.
