Diff Viewer

Compare clips side by side and see exactly what changed — between two clips or between an edited clip and its original.

The diff view highlights additions in green, removals in red, and modifications in yellow with word-level detail. You can merge individual lines or entire blocks in either direction.

How to use it

There are two ways to open the diff view:

Mode How to open
Clip vs. Clip Ctrl+Click two clips, then press Ctrl+D or right-click Compare
Clip vs. Original Select a single edited clip, then press Ctrl+D or right-click Diff to Original

Once open:

  1. Switch view mode — click S (Side-by-Side) or U (Unified). The view auto-switches based on pane width.
  2. Merge a line — hover over a changed line to see merge arrows (>). Click to merge that line. Click >> to merge an entire block at once.
  3. Reverse direction — hold Ctrl while clicking a merge arrow to merge right-to-left.
  4. Undo a merge — Ctrl+Z.
  5. Options (hamburger icon) — ignore whitespace, ignore case, or strip a regex pattern before diffing.
  6. Swap — flip left and right sides.
  7. Full pane — expand the diff to fill the entire workspace.
  8. Close — click X, press Esc, or change your clip selection.

Tips & gotchas

  • Compare only works with text clips — it is disabled for image clips and masked clips.
  • Identical clips show all text with no highlighting and an “identical” badge.
  • Merges are saved immediately to the database. Ctrl+Z undoes within the session; after closing, individual merge history is gone — but if the clip had an original saved, you can still Revert to Original via right-click.
  • A * dirty flag shows how many merges have been applied in this session.
  • A confirmation dialog appears on the first merge per session.
