Neverenders takes a single video or audio file and returns a defensible record: cryptographic chain of custody, tamper and edit detection, full transcription, frame and timeline reconstruction, and a structured legal review. Built for matters where the authenticity of the recording is the question.
When the recording is the evidence, it should be examined like evidence. Sealed the moment it arrives, tested by methods that do not depend on each other, and written so every finding can be reproduced and challenged.
Every file passes through the same layered pipeline. Each layer is independent, so a result never depends on a single tool agreeing with itself.
Processing runs locally on controlled hardware. The original never leaves custody, and every stage writes its own machine-readable record.
Ingest, hash, and lock the original. Create a working copy and capture the full technical profile.
Structural tamper checks across container, packets, frame types, and metadata.
Speech to text with word timing and speaker labels where the audio supports it.
Spectral, silence, loudness, and mains frequency analysis for edit signatures.
Keyframe extraction, text and clock reading, and per-frame error level analysis.
Fuse every event and reconcile the on-screen clock against real elapsed time.
Rights and procedure scan plus a structured written review for counsel.
One self-contained report with exhibits, plus a PDF for filing.
A worked example using synthetic footage. The on-screen clock and the actual elapsed footage are tracked separately, then compared. Open the showcase for the full walkthrough.
One interval where the burned-in clock advanced differently from the elapsed footage. The clock jumped 181 seconds while only 1 second of footage played. Strong indicator of paused recording or removed footage. The full unedited original and metadata should be demanded.
Intake to report. Originals stay under custody throughout.
You provide the source file. It is hashed on arrival and the hash is recorded before anything else happens.
The full pipeline runs on controlled hardware. No upload to third-party services is required for the forensic work.
You receive a self-contained report and PDF. The findings, exhibits, and chain of custody log travel together.
Your report is placed behind a login here. Only you and the people you authorize can open it.
