setCurrentRow, setHidden, and setText all trigger Qt internal scroll
recalculation. Now save scrollbar value before these operations and
restore it after, then use scrollToItem only to bring off-screen
selections into view.

The lock-mode path was only updating the crop bar but not the video
overlay or random overlays. Now sets _crop_center and calls the
appropriate overlay update.

Portrait lines are red, square lines are blue — matching the video
overlay. Both shown simultaneously when both random options are on.

_apply_playlist_filters now syncs _hide_exported from checkbox before
refreshing visibility, so exported files are hidden immediately on
startup without needing to toggle the checkbox.

PreviewLabel widget replaces plain QLabel, draws dimmed areas outside
the crop window and blue border lines matching the crop bar position.
Updates live when portrait ratio or crop center changes.

- _apply_visibility wraps setHidden loop with setUpdatesEnabled and
scrolls back to current item after
- _refresh_playlist_checks wraps mark_done/unmark_done loop similarly

profile-hidden OR (hide_exported AND done)
- mark_done/unmark_done no longer touch setHidden directly
- Session resume selects first visible item after filters applied
- add_files defers to _select_first_visible to skip hidden items

Switching profiles now clears the overwrite path, button states, and
next-label so stale state from the old profile doesn't persist.

The previous border:none rule hid the dropdown indicator entirely,
making combos look like plain text fields.

Each profile has its own set of timeline markers, so the same video
can be cut with different settings (e.g. landscape vs portrait) without
markers interfering. Profile selector in the top bar, persisted in
QSettings, stored per-row in the DB.

Emit marker_clicked before seek, and use a flag to prevent
_on_cursor_changed from immediately clearing the overwrite state

Legacy records get new columns with sensible defaults and are preserved
as markers. No more data loss on schema upgrade.

DB now stores short_side, portrait_ratio, crop_center, format,
clip_count, and spread per export. Clicking a marker restores all
fields to the original export settings.

Each batch export creates a subfolder named after the group (e.g.
clip_001/) containing all sub-clips and their audio files. Keeps
the top-level export folder clean.

Pending marker uses cursor position for the whole batch. DB markers
deduplicated by start_time since all sub-clips share the same cursor.

When the random portrait checkbox is on and portrait dropdown is Off,
the crop bar appears and the video overlay shows 2 red vertical lines
(instead of filled red bands) indicating the 9:16 crop boundaries.
Clicking the crop bar or video adjusts the crop center position.

Small panel to the right of the video displays the frame at cursor +
clip_span. Updated with 300ms debounce on cursor move, spread/clip
count change, and file load. Uses ffmpeg to grab a single PNG frame
off the main thread.

Checkbox '1 random portrait' in settings row. When checked, one random
clip in each batch receives a randomly chosen portrait ratio (9:16, 4:5,
or 1:1) with a random crop center. The rest use the global portrait
setting. Disabled for single-clip overwrite exports.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Each export generates clip_NNN_0, clip_NNN_1, clip_NNN_2 offset by the
spread value (2–8s, default 3s). Preview plays the full span covered by
all three clips. Marker click still overwrites a single clip.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Targets last export by default; targets marker-selected clip when one is
active (shown as "Delete <name>"). Clears on cursor move if no last export.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Each exported clip writes an entry to <folder>/dataset.json containing
its relative path, sound label, and fps. Re-exporting to the same path
updates the existing entry (upsert). Empty labels are skipped.

- Queue ✓: mark files green after export and on drop if already in DB
- Export folder auto-created if missing
- Scrub while playing: cursor drag seeks and continues playback
- Counter auto-advances past existing files on disk
- Instant pending marker on timeline when export starts
- WebP quality 92 + lanczos scaling
- seek() guard against unloaded state (SystemError fix)

- Editable label combo with DB history (most recent first)
- Click marker to arm overwrite mode (↺ indicator, re-exports same file)
- Portrait crop overlay: red bands on cut regions (paused only)
- Cache video dimensions to avoid mpv property reads in paintEvent
- Queue marks done files with ✓ on drop and after export
- Export folder created automatically if missing
- Play continues from new position when scrubbing during playback
- Counter auto-advances past existing files on disk

mpv embedding:
- Replace wid/QOpenGLWidget with QOffscreenSurface + QOpenGLFramebufferObject
+ QPainter readback — works on Wayland/KDE without sub-surface compositing
- Force desktop OpenGL 3.3 core profile before QApplication (fixes black output on GLES)
- Timer-based render polling (16 ms) replaces signal-flood from mpv C thread;
fixes playback animation and scrubbing preview
- Fix AB-loop: set ab-loop-a/b to "no" on stop (0 means infinite in mpv)
Timeline:
- Full redesign: time ruler with adaptive major/minor ticks, playhead triangle
handle, selection region with edge lines, numbered marker badges
- Height 160 px; layout collapsed from 4 rows to 2 below timeline
- Markers appear immediately on export (optimistic update before ffmpeg finishes)
- Right-click marker → context menu to delete from DB
Hotkeys:
- Replace keyPressEvent with QShortcut(ApplicationShortcut) so keys work
regardless of focused widget; MpvWidget gets NoFocus policy
Export:
- WebP: switch lossless→lossy quality 85, compression_level 1 (~10x faster)
- Add -threads 0 for full CPU utilisation during decode/filter
- Remember last export folder across sessions via QSettings

- TimelineWidget.set_cursor: skip update() when clamped value is
unchanged (e.g. clicking at the boundary repeatedly).
- MainWindow: cache container_fps in self._fps on file load; keyPressEvent
reads the cached value instead of hitting the mpv property on every key.
- PlaylistWidget: add _path_set (set[str]) alongside _paths (list[str])
so duplicate detection in add_files is O(1) instead of O(N).
- SettingsDialog._on_install: quit+wait any previous SetupWorker before
starting a new one, preventing leaked threads and duplicate signal
connections on repeated installs.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- PlaylistWidget._select: only update the two items whose label changes
(old current → plain name, new current → add ▶) instead of rewriting
every item in the playlist.
- TimelineWidget: pre-compute (t/duration, path) fractions in
_hover_cache on set_markers/set_duration so mouseMoveEvent avoids
dividing by duration on every pixel of mouse movement.
- CropBarWidget: cache QPen in __init__ instead of recreating per frame.
- _step_cursor: update label/state immediately and start the timeline's
existing _seek_timer instead of calling _on_cursor_changed directly,
so held arrow keys are debounced the same as mouse drag.
- _refresh_markers: call _get_markers_for(filename) directly after
export (exact match known) and only fall back to fuzzy find_similar
when no exact-match rows exist.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- TimelineWidget: debounce cursor_changed signal with 16ms timer so
mpv.seek is called at most ~60/s during drag; flush on mouseRelease.
Cache QPen/QFont objects in __init__ instead of recreating per frame.
- _normalize_filename: compile _QUALITY_RE and _SEP_RE once at module
level instead of on every call.
- ProcessedDB: add check_same_thread=False; add _get_markers_for() to
avoid a second find_similar pass; store db path.
- _DBWorker(QThread): runs find_similar + _get_markers_for off the main
thread. _after_load starts the worker instead of blocking; stale
results discarded if the user loads a different file first.
- MainWindow: reuse self._settings instead of creating a new QSettings
instance in the mask row setup.

Arrow keys / J / L: step one frame; Shift = 1 second jump
Space / P: toggle play/pause
