The Videographer and his equipment make little impact on the Deposition session. He will confirm that his equipment is working properly and interferes in no way with the Testimony. An advantage is the coordination and order he brings to the Deposition which makes things run more smoothly, letting the attornies focus on their case undisturbed.
Working hand-in-hand, the Court Reporter's Written Transcript and the Legal Cameraman's Video Record provide a complete record of a witness' verbal testimony as well as the subtile clues their demeanor reveals.
Depositions are essentially legal testimony given outside a courtroom. This Testimony is legally binding, and for that reason, the witness is sworn in by the Court Reporter or another Officer of the Court to tell the truth to the best of their knowledge.
Attorneys and any associates attending Depositions may bring evidence in the form of documents or exhibits. A Court Reporter carefully writes down every word said during the Deposition, and their Transcript is the official record of the proceedings.
The Court Reporter's Transcript is invaluable, but it cannot reveal the verbal intonation, attitude, and "demeanor" of the witness. This is why successful attornies are now using Video in Depositions to make up for the deficits of a written document.
