The law of demonstrative animations

While affirming a $4 million judgment related to a truck accident – most of which involved a series of Daubert challenges — the Fifth Court provided some rare appellate guidance about the use of video animation in the courtroom. Specifically, Smith – the plaintiff’s accident reconstruction expert – prepared an animation to accompany and illustrate his testimony about how the accident occurred.

The Court found no error. As to foundation, it said: “As to the video animation, we note the video was not admitted into evidence but was shown during Smith’s testimony for demonstrative purposes. Defense counsel objected ‘on the grounds of 403.’ Smith testified he measured Gaston’s truck and two similar trailers ‘in order to get data to fill in the animation.’ It was not possible to ‘match tire to track,’ but Smith made a generalized analysis of marks on the roadway he described as an ‘approximation.’ Smith testified the animation was not a simulation and ‘not an exact replication of what happened,’ but it was ‘an accurate representation of what occurred.’”

As to admissibility and waiver, it held: “Earlier in the trial, Smith was allowed to express his underlying opinion without objection when the testimony was presented to the jury. Since the animation was a graphic depiction of the opinion admitted into evidence without
objection, Greenwood’s trial objection to the video depiction of that opinion was waived. Video animation and other demonstrative evidence that ‘summarize, or perhaps emphasize, testimony are admissible if the underlying testimony has been admitted into evidence, or is subsequently admitted into evidence.'” (citations omitted) Greenwood Motor Lines v.
