During which event can the videographer's video be used for playback?

The correct answer is that the videographer's video can be used for playback during a trial. In legal proceedings, a trial is the formal process where evidence is presented and arguments are made in front of a judge or jury. The use of video recordings, such as depositions taken before the trial, is often permitted in trial settings to help establish evidence or to clarify witness testimony. This allows jurors to see and hear the testimony as originally presented, providing a more dynamic and impactful form of evidence compared to just reading a transcript.

While video recordings can also be relevant during hearings and depositions, their primary utility pertains specifically during the trial when all evidence, including video depositions, is actively considered by the judge or jury. A conference typically does not involve the presentation of evidence in a legal context and is usually more informal.
