play().
VideoPlaybackRef.playreturnsPromise<void>(seesrc/components/video-editor/VideoPlayback.tsxLines 296-306). The call is not awaited and has no rejection handler.

43-75: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick winSkip the retry when telemetry samples already loaded, and extract the duplicated retry block.
The retry condition in the success branch (Lines 48-58) does not check
result.samples.length. A fresh recording that returns samples on the first call still schedules up to 12 additionalgetCursorTelemetrycalls at 350 ms intervals, becausependingFreshRecordingAutoZoomPathRef.current === videoPathstays true until auto-suggest consumes the telemetry. Each retry rewritescursorTelemetryandcursorTelemetrySourcePath, which re-runs the normalization memos and the downstream timeline consumers.The same retry block is also duplicated in the catch branch (Lines 64-74).
♻️ Proposed fix: retry only when samples are missing, with one shared helper

historyRef.currentduring render, and Line 163 keepsversionalive only to satisfy the linter. The returned flags are correct today because every mutation path callssyncButtons(), but the correctness depends on that invariant holding in future edits, and reading a mutable ref during render is not safe under concurrent rendering.Replace the counter with the two derived flags.

Inline comments:
In `@src/components/video-editor/captions/useAutoCaptionController.ts`:
- Around line 158-182: Update the source-path resolution flow around
resolveAutoCaptionSourcePath so non-file media-server URLs are resolved to local
readable paths before syncActiveVideoSource, setVideoPath, or caption
generation. If the URL cannot be resolved, reject it and preserve the existing
“No source video is loaded” handling rather than passing the URL to IPC or
ffmpeg.
In `@src/components/video-editor/export/useExportDialogActions.ts`:
- Around line 61-62: Update resolveExportStartSettings to reject export when
video.videoWidth or video.videoHeight is zero or otherwise unavailable, instead
of falling back to 1920x1080. Preserve the existing metadata-based dimensions
once both values are available.
In `@src/components/video-editor/export/useExportDimensions.ts`:
- Around line 50-59: Update gifOutputDimensions to use the existing
sourceDimensions value instead of reading videoPlaybackRef.current directly,
while retaining gifSizePreset and GIF_SIZE_PRESETS in the calculation. This
makes the memo recompute through sourceDimensions’ isPreviewReady dependency
when video metadata becomes available.
In `@src/components/video-editor/hooks/useClipRegionCommands.ts`:
- Around line 82-105: Update the split-clip logic around setClipRegions to find
the target and generate leftId/rightId from the current clipRegions before
dispatching the state update. Move the selectedClipId update outside the
updater, and keep the setClipRegions callback limited to constructing and
returning the replacement regions without mutating refs or triggering state
updates.
In `@src/components/video-editor/hooks/useEditorGlobalInteractions.ts`:
- Line 51: Restrict the Tab suppression in the window capture listener to the
timeline surface or an explicit timeline shortcut target, rather than every
non-editable element. Update the condition around the event.key === "Tab" check
in useEditorGlobalInteractions so normal focus navigation and modal focus traps
continue receiving Tab events.
In `@src/components/video-editor/hooks/useTimelineProjection.ts`:
- Around line 59-60: Update the bootstrap logic in the timeline projection flow
around timeline.setClipRegions and timeline.setSpeedRegions so persisted
speedRegions are not cleared when clipRegions is empty. Transfer the persisted
speeds onto the derived clips, or retain the speedRegions state, while
preserving existing behavior for projects without speed regions.
In `@src/components/video-editor/hooks/useZoomRegionCommands.ts`:
- Around line 78-80: Update the user-created zoom region command near
markFreshRecordingSuggestion to set mode to "manual" instead of "auto". Preserve
mode "auto" only in handleZoomSuggested so manual regions are not removed by
automatic zoom cleanup.
In `@src/components/video-editor/layout/EditorDialogs.tsx`:
- Around line 139-141: Update the unsaved-changes dialog in EditorDialogs to use
the received translator t for its four hardcoded English strings, including the
DialogTitle, DialogDescription, and related action text around the referenced
dialog. Add the corresponding translation keys while preserving the current
English text as each key’s fallback, and keep the existing interpolated action
label behavior intact.
In `@src/components/video-editor/layout/EditorExportMenu.tsx`:
- Line 243: Update the filename extraction in the export menu rendering to
handle both forward-slash and backslash path separators, so Windows and POSIX
paths display only the basename. Preserve the existing behavior for valid file
paths and use the nearest existing export path display logic around
exportedFilePath.
In `@src/components/video-editor/layout/EditorPreviewPanel.tsx`:
- Around line 376-384: Add an accessible name to the range input controlling
previewVolume by associating it with an existing visible label or adding an
appropriate aria-label. Keep the current slider behavior and styling unchanged.
In `@src/components/video-editor/layout/EditorSidebar.tsx`:
- Around line 103-104: Update the account button in EditorSidebar to use the
component’s existing t(...) localization function for both the toast.info
message and the title, adding the corresponding translation keys while
preserving their current meanings.
In `@src/components/video-editor/layout/EditorVideoPreview.tsx`:
- Line 95: Update the VideoPlayback invocation in EditorVideoPreview to pass
appearance.borderRadius instead of a fixed zero radius, preserving the
configured radius through layoutVideoContentUtil and the preview frame.
In `@src/components/video-editor/presets/useVideoEditorPresets.ts`:
- Line 81: Exclude appearance.webcam.sourcePath when constructing
currentSnapshot, and update applySnapshot to preserve the existing webcam
sourcePath while applying the preset’s remaining webcam settings. Keep
sourcePath unchanged across preset application.
In `@src/components/video-editor/project/useInitialEditorSource.ts`:
- Around line 163-176: The initialPreferences assignments in applyLoadedProject
should only run when no project is loaded; preserve the loaded project’s editor
values and lastSavedSnapshot when applyLoadedProject has initialized a project.
Guard the appearance, aspect-ratio, export-settings, and related preference
updates with the existing project-loaded state condition, while retaining them
for the no-project initialization path.
In `@src/components/video-editor/project/useProjectLibraryController.ts`:
- Line 282: Update the callback dependency handling around
captureProjectThumbnail and saveProject to read currentTime from a ref instead
of listing the rapidly changing value as a dependency. Keep the ref synchronized
with the latest currentTime, while preserving the existing frame-capture
behavior and preventing save subscriptions and autosave effects from being
recreated during playback.
In `@src/components/video-editor/project/useProjectSaveActions.ts`:
- Around line 109-112: In the forceSaveAs or missing targetPath branch, await
openProjectSaveDialog before returning its result so the surrounding finally
block runs only after the dialog closes; preserve the silent false path and
existing projectDisplayName/fileNameBase arguments.

gating and visual styling where supported, and ensure the title is provided for
accessible dialog semantics.

What changed
This breaks the video editor god component into focused modules for editor state, timeline commands, project lifecycle, layout, presets, captions, and export behavior. VideoEditor.tsx is now a small composition root while the extracted files stay at or below 500 lines.
It also fixes the responsiveness regressions found during manual testing. Initial source hydration now runs once, history and preference persistence react only to relevant state, autosave and export handlers remain stable, and local media is approved before URL resolution. The project folder switcher is mounted in the normal editor view and opens immediately while its library refreshes in the background.
Why
The previous editor component mixed rendering, persistence, project operations, timeline editing, playback coordination, and export orchestration in one file. That made changes risky and allowed unrelated renders to retrigger expensive effects.
Verification
The remaining project-open and project-import flows can now be tested through the restored folder switcher.
