Legal Video Evidence Preparation

Video evidence, prepared the way
it actually has to be used.

Because the case won't wait for a problem video.

Proprietary DVR exports, oversized files, mixed-source footage, files that won't open or won't play reliably — 4KVT prepares a standardized playback copy for review, presentation and courtroom playback — your original never leaves your custody. Use us to solve a problem file or prepare one before a deadline. Flat price per file. No subscription. No contract. Processing is fully automated — no person at 4KVT ever views your footage.

🔒 Original never modified — chain of custody intact 🗑 Auto-deleted from our servers after 7 days ⚡ 24/7 automated — no staff views your footage
Real-world video files with real problems — DVR, dashcam, doorbell and phone footage that won't open, is too large, or has no audio — prepared by 4KVT into one court-ready H.264 MP4 with a full evidence report.

Why this happens: Video evidence comes from many different sources — CCTV and DVR systems, dashcams, doorbell cameras, phones and other recording devices — and the files they produce aren't always suited to the way a legal team needs to use them. Some use proprietary formats like .DAV, .IFV and .264; others may be too large, incompatible with standard playback systems, or simply unreliable when it matters. Preparing that footage for dependable use is a technical task, not a legal one. That's the task we do.

How Video Becomes a Legal-Workflow Problem.

A file does not have to be broken to cost staff time or create a presentation problem. These are the recurring situations 4KVT is built to handle.

Pattern 1

The DVR Export That Opens Nowhere

The incident location hands over a USB drive or download from their security system. The files are .DAV or another proprietary format. Nothing in the office plays them — and the courthouse equipment won't either.

Pattern 2

Plays on Your Phone, Dies in the Courtroom

The doorbell or phone clip plays fine in one app but freezes, buffers, or shows a black screen on the courtroom AV system. Codec and container incompatibility — invisible until presentation day.

Pattern 3

The File With No Sound

The video plays but the audio stream is non-standard. Players silently drop it. Reviewers and juries watch footage with no sound — or staff burn an afternoon trying codec packs they shouldn't be installing.

Pattern 4

Five Sources, Five Formats

Dashcam, doorbell, phone, store DVR and investigator footage all arrive differently. Standardized playback copies reduce format switching and make review and presentation more predictable.

Pattern 5

It Plays — But Not Reliably

A file may open yet buffer, freeze, start slowly or lose audio on another machine. We prepare a broadly compatible H.264 MP4 with standardized audio and Faststart for immediate playback.

Courts Set the Rules. We Meet Them Before You File.

Federal and state courts increasingly impose their own video requirements — and generally won't fix a file for you once it's in front of them.

Size limits are real. Some courts' e-filing systems cap most video exhibits well under a gigabyte, and formats outside a short accepted list aren't taken at all.

Some courts won't convert it for you. Several districts advise that material requiring proprietary software or codecs the court can't review simply won't become part of the record.

No time to troubleshoot at counsel table. Courts generally don't provide court or jury time to fix playback problems mid-proceeding — testing beforehand is the only real option.

Requirements differ by court and by judge, so we don't promise any specific court's acceptance. What we prepare is a standardized playback copy built to sit inside the common limits — your original stays your authoritative copy throughout.

One Upload. Two Things Back.

Send a copy whether it is incompatible, oversized, mixed-source, unreliable in playback, or simply being prepared before a hearing. You receive a standardized playback copy and a processing documentation report — everything logged, your original untouched.

Processing Documentation Report

  • ✓ Source file specs as received (container, codec, size, duration, audio)
  • ✓ Output file specs as delivered
  • ✓ Every processing step applied, listed in plain English
  • ✓ Confirmation that the visual and audio content itself was not altered — only the container and codec were converted for playback compatibility
  • ✓ Deletion confirmation — file removed from our servers after the delivery window

Three Steps. Your Custody, Your Deadline.

No software to install. No new system for your staff. A copy goes up; a playable copy comes back.

Send a copy of the evidence file — up to 10 GB, up to 2 hours. Your original stays in your custody, untouched. The chain of custody is never interrupted.

2

Automated Processing

Our system detects the format issue and prepares the playable copy. Fully automated — no person at 4KVT views your footage. Privileged material stays privileged.

3

A private link by email: the playable evidence copy and the documentation report. The secure link is valid for 7 days — then the file is automatically removed from our servers.

One Flat Price Per File. No Retainer.

Priced by file size, not by case value. No subscription, no contract, no minimum — pay only when you send a file.

Process This File
Built for evidence files up to 10GB and 2 hours. Larger native exports — full multi-day NVR dumps, raw surveillance archives — are better served by a forensic AV vendor. Files above our limits aren't accepted, automatically, before you pay. The same applies to files our system can't prepare — most .DAV exports convert cleanly, but some firmware-encrypted files cannot. If yours can't, you'll know immediately, and you never pay for a file we can't prepare.

Six Concerns. One Answer Each.

Before any firm sends privileged material to an outside service, these are the questions that must be answered.

🛡️

Your Original Never Leaves Your Custody

You upload a copy. Your original file stays on your system, unaltered. Chain of custody intact.

🔏

Privileged & Confidential — Automated Only

No person at 4KVT views your footage. No reviewer, no editor, no contractor. The pipeline is automated end to end.

⚡

Fast, Automated Turnaround

Same-day processing. 24/7 automated file submissions and processing, with a private download link by email returned generally within the hour.

🗑️

Auto-Deleted After 7 Days

Files are removed from our servers automatically after the delivery window. We are a processing step, not a storage service.

👁️

Never Shared, Stored, or Reused

Evidence is never used for training, marketing, or any purpose beyond your single job.

📄

No Contract. No Subscription.

Pay per file, only when you send one. No retainer, no minimum, no sales contact — ever.

We Prepare the Playable Copy. You Keep the Legal Judgment.

Technical format preparation only — clearly bounded, so you know exactly when to use us and when to call someone else.

✅ What We Prepare

  • ✔ Proprietary CCTV / DVR / NVR exports — .DAV, .IFV, .264 and similar
  • ✔ Doorbell, dashcam, and phone video that won't open or play reliably
  • ✔ Files that play but buffer, freeze, or have no audio
  • ✔ Mixed sources standardized into one playable format
  • ✔ Right-sized copies of oversized exports (within limits)
  • ✔ Pre-hearing / pre-trial preparation of files that already play — standardized copies for more predictable playback
  • ✔ Preparation for review, presentation, and courtroom playback

❌ What We Are NOT

  • ✖ Content analysis, authentication, or opinion work — that is expert-witness territory; we do format only
  • ✖ Frame enhancement or alteration — we never touch content, frames, or metadata of your original
  • ✖ Tape digitization — we handle files, not physical media
  • ✖ A replacement for your eDiscovery platform or litigation support vendor
  • ✖ A subscription, retainer, or long-term contract
✔ Use us when a file won't play, won't fit, won't behave consistently — or when you want a standardized playback copy before the deadline.

Integrity of Evidence — Read Before Uploading

4KVT performs technical format preparation only, on a copy of your file. We do not view, analyze, enhance, or alter content beyond that technical conversion. You send us only a copy of the file — never the original. We modify that copy's container, codec, and audio so it plays on standard equipment; your original stays in your custody, untouched, the entire time. The copy is deleted from our servers within 7 days. Every step applied to the copy is listed in your documentation report. What we deliver is a playable viewing copy, clearly documented as such — your original remains your authoritative copy. If your matter requires forensic analysis, authentication, or enhancement, engage a qualified forensic AV examiner — we are the straightforward format step, not the expert
