Spot reused footage across episodes, before delivery.

What it does

On multi-episode projects, clips get reused — sometimes intentionally, often not. DejaView compares your episode sequences against each other and surfaces every instance of duplicated footage: exact matches, clips used at different in/out points, and shots from the same card used in proximity across episodes. Load your AAF, XML, or EDL files, set your tolerance, and get back a clear, colour-coded Excel report showing exactly where the reuse happens and which episodes are affected.

Everything included

Exact duplicate detection

Flags clips that appear in multiple episodes with the same source timecode range — definitively the same shot used twice.

Partial duplicate detection

Catches the same clip used with a different in/out — a different part of the same take, across episodes.

Proximity duplicate detection

Finds clips from the same card or reel used near each other across sequences — likely reuse, even if the names differ.

AAF, XML & EDL support

Load Avid AAF, Premiere Pro XML, or CMX 3600 EDL files. Mix formats freely in a single job.

Fuzzy name matching

Configurable similarity threshold catches renamed or slightly modified files that are the same underlying clip.

Framerate-aware

Full NTSC fractional framerate support — 23.976, 29.97, 59.94 — handled without rounding errors.

Excel duplication report

One colour-coded report with an episode-by-episode breakdown, a full duplication index, and editorial analytics.

Offline & private

All processing happens locally. No uploads, no accounts, no internet connection required.
