Short answer: Triage Forensics carries out video authentication and explains the findings in plain language that judges and juries can follow, both in written reports and when giving oral evidence at trial.

The technical side of authentication is covered in our guide to video forensic authentication. This page is about the part lawyers often worry about most: making the findings understandable without making them less accurate.

The problem with technical evidence

A finding such as “frame interpolation artefacts indicate a splice at 00:12:07” may be correct, but on its own it means little to a jury. If jurors can’t follow the reasoning, they either ignore the evidence or accept it on trust, and neither is fair to the parties.

How we translate findings

Lead with the conclusion. “In my opinion, about four seconds of this footage has been removed.”

Show, don’t just tell. Side-by-side frames, a timeline of the clip with the problem marked, or a short demonstration of what a normal file looks like next to this one.

Use everyday comparisons. Re-compression can be explained as photocopying a photocopy: each generation loses detail and leaves traces. A missing section can be likened to a page torn out of a numbered notebook.

State the confidence level and the limits. What the analysis shows, what it doesn’t, and what would change the opinion.

Simple, but not simplified

Plain language must never cost accuracy. Every analogy we use is checked against the underlying technical finding, and the written report sets out the full methodology so that an opposing expert can test it. If counsel or the court want the technical detail, it’s there.

Preparing for cross-examination

Clear evidence also holds up better under cross-examination. When the reasoning is transparent and the limits are stated up front, there’s little room for the suggestion that the expert has overreached.

Frequently asked questions

Can video authentication findings be explained to a jury?

Yes. Findings are translated into plain language with analogies and visuals, and honest limits are stated, so judges and juries can weigh the evidence properly.

Do you give expert evidence at trial?

Yes. Where a matter proceeds, we prepare compliant expert reports and attend to give oral evidence and respond to cross-examination.
