Amped Podcast: The Evidence Talk

In “Courtroom Presentation: Explaining Technical Topics Clearly and Building Demonstratives”, you’ll join Emi Polito and Sam Abbott from Amped Software for a practical conversation on one of the most important - and often underestimated - parts of forensic video analysis: presenting video evidence clearly in court.From early casework mistakes to powerful courtroom demonstratives, Emi and Sam explore how the presentation of video evidence can shape understanding, influence decision-making, and help judges and juries avoid dangerous misinterpretations.They discuss real-world challenges, including low frame rates, compression, lighting, motion blur, timing, 2D perspective, slowed-down footage, still image sequences, annotations, and the limits of what a video analyst should - and should not - say in court.The episode closes with a mock cross-examination, giving listeners a front-row seat to the kinds of questions video experts may face when their work is challenged on the stand.Episode outline:01:00 - Why evidence presentation matters in court01:25 - Sam’s first presentation case: 48 hours of footage and multiple DVRs02:12 - Early lessons learned from building timelines without the right tools03:05 - Emi’s route from television into forensic video analysis04:41 - Using broadcast skills in early courtroom presentations06:46 - The impact of 3D reconstruction and persuasive demonstratives08:41 - Explaining technical limitations so evidence is not misinterpreted11:11 - Video playback speed, low frame rates, and the risk of misleading the jury13:14 - Slowed footage, frozen frames, and maintaining an unbiased presentation15:17 - Delivery formats: DVDs, compression, and courtroom limitations17:24 - Using image sequences, PDFs, annotations, and chronologies of events19:41 - What to do when key contact is not captured between frames21:40 - Motion blur, frame-by-frame analysis, and simple analytical reporting23:35 - Staying within your expertise as a video analyst25:32 - Courtroom challenges: answering clearly without over-explaining27:21 - Preparing for court when the case is years old29:10 - Notes, audit trails, and documenting every step of the workflow31:37 - Jury bundles, illustration packs, and making sure demonstratives are seen33:49 - Mock cross-examination begins36:13 - Compression, artifacts, and what the jury is really seeing38:15 - Lighting, clarity, and evaluating footage quality40:10 - Contact, obscuration, and limits of interpretation42:11 - Perspective, timing data, frame rates, and validation

In “CCTV Nightmares: Chain of Custody Secrets from Scene to Courtroom”, you’ll join Lucy Carey-Shields (Forensic Analyst at Amped Software) and Blake Sawyer (US Operations Director at Amped Software) as they discuss real chain-of-custody pitfalls they’ve seen in the field: mismatched camera times across multiple locations, systems accidentally reformatted, footage lost after a “simple” time correction, and exports that quietly change the evidence.You’ll also get practical guidance on:Capturing the most forensically sound version (why proprietary exports matter)Starting continuity early with hashing and disciplined handling of USB-based collectionsAvoiding “quick conversions” that can drop frames or distort timingThe frontline checklist: stop and think, document everything, and do a time checkIf you collect, process, or present video evidence, this episode gives you a clear, field-tested mindset to protect integrity from scene to courtroom.Episode outline:00:12 - Official welcome + host intros (Lucy Carey-Shields and Blake Sawyer)02:41 - How they each got into video forensics04:45 - Blake’s “trial by fire” case: missing person investigation, large-scale CCTV collection, building a video workflow06:11 - Real-world chain-of-custody pitfalls from the field08:35 - Starting continuity at the scene: disciplined USB collections, hashing as a “digital fingerprint”, and clean handoff to storage/server10:52 - Handling digital evidence like physical evidence: don’t change data, document everything, be competent if changes are unavoidable (UK ACPO principles)13:16 - The pressure problem: modern casework data volumes and time constraints; why asking the right questions early matters13:57 - Cloud video (Ring/doorbells): consent vs legal process, exigent circumstances, and getting the “best” version (plus confirmation from the provider)17:04 - Why proprietary exports matter: least-altered version, stronger integrity, and downstream needs (court playback, public release without “video-of-video”)19:33 - The danger of “quick conversions” (e.g., FFmpeg): dropped frames, skipped data segments, lost timing; why forensic tools must preserve frame/time metadata21:58 - Testifying without “nerd talk”: translating technical video issues for humans/juries23:44 - Training & certification: LEVA vs IAI workflows, what gets tested, and why it changes how you approach analysis/reporting26:01 - Evidence retention and storage: CDs/tape/cloud tradeoffs, vendor lock-in risk, and long retention timelines29:09 - Frontline checklist (the “3 simple rules”)35:54 - Common agency mistakes: detective-managed files, cloud upload authenticity concerns, and the “one flash drive for every case” problem
