Dupe - Overview
Dupe cross-references clips across multiple sequences or episodes to surface re-used shots. It works with the same parsed source formats as Sheet - Premiere XML, Resolve XML, FCPXML, CMX 3600 / Avid EDL, and OTIO - and is designed for long-form work where the same camera roll can appear across many episodes. Multi-track EDL sets are collapsed to one cut before matching, so a multi-file track import behaves like one episode in the Matrix.
When to use it
Section titled “When to use it”- Episode review: Check whether shots from the episode you are cutting also appear in other episodes.
- Post-delivery QC: Confirm no clip from a previous episode was accidentally included in a new cut.
- Music clearance: Find every use of a clip that carries a specific music track.
- Archive: Build a complete cross-reference of every clip across a series.
How it works
Section titled “How it works”Dupe matches clips by source file name, reel, and source timecode range. Gap and overlap values are measured in source timecode space, not timeline/master sequence timecode.
Matches are grouped into three kinds:
| Kind | Meaning |
|---|---|
| Exact | Same clip name, and the source timecode ranges overlap. |
| Partial | Same clip name and same reel, but the source ranges don’t overlap. |
| Proximity | Different clip names from the same camera card, appearing within a configurable distance of each other in the timeline (default 5 clips; settable 1–50). |
An optional Fuzzy name matching mode (off by default) uses similarity-based clip-name comparison - useful when clips have been renamed but rarely worth the false-positive cost. Configure its thresholds in Settings → Dupe.
You can filter Exact, Partial, and Proximity independently in the toolbar, and the table updates each duplicate group based on the remaining visible uses.
Display Names
Section titled “Display Names”Dupe uses each open sequence’s Display Name for episode labels, Matrix headings, Target Episode names, and exports. SequenceSuite starts with a sensible label from the sequence or filename, but EDL filenames can vary wildly between productions.
To rename a label without touching the file on disk, right-click a sequence in the sidebar and choose Rename Display Name…. Use Reset to Original Name to go back to the imported name.
Episode Codes
Section titled “Episode Codes”Alongside the Display Name, each sequence has a short Episode Code - a compact identifier like EP101 or S01E02 used in the Dupe table’s episode pips, Inspector, and PDF exports. SequenceSuite derives it automatically from the Display Name by scanning for common patterns (EP, E, S##E##). If no pattern matches, it falls back to initials and any trailing numbers from the filename.
The Episode Code is intentionally short so Dupe rows and PDF pages remain readable across many episodes. If the auto-derived code is wrong or two episodes collide on the same label, right-click the sequence in the sidebar and choose Edit Episode Code…. To restore the auto-derived value, choose Reset Episode Code.
Editing the Episode Code does not change the Display Name or rename the source file on disk.
Target Episode
Section titled “Target Episode”For series work, set a Target Episode when you want to ask: “where are shots from this episode used elsewhere?”
For example, if EP101 is your target:
- Dupe only shows duplicate groups involving EP101.
- Rows are anchored to EP101’s timeline and source range.
- Matches that only occur between EP102 and EP103 are hidden.
- Mirrored rows are de-duplicated, so the same EP101/EP102 match is not shown twice.
Set the target with the target icon beside a file, or right-click the sequence in the sidebar and choose Set as Target Episode - the option works on a multi-track cut’s group row too, so a V1/V2/V3 EDL set can be targeted as one episode. The active target shows as a chip in the results bar; click the chip’s ✕ (or choose Clear Target Episode) to return to the whole-set view.
