In `@src/components/ai-edition/v4/MediaStage.tsx`:
- Around line 98-102: add colocated Vitest coverage for MediaStage’s
addSelectedToTimeline action, verifying the selected asset ID is forwarded to
onAddToTimeline and that no call occurs when selected is absent; if rendering
MediaStage, use the jsdom environment directive, otherwise keep the default Node
environment.
- Around line 98-101: Update addSelectedToTimeline so the success toast uses the
displayed asset name, falling back to basename(selected.originalPath) when
selected.label is empty, matching the media card’s existing name-resolution
behavior.
In `@src/components/ai-edition/VirtualPreview.tsx`:
- Around line 188-216: Update the WebAudio setup effect around audioGraphRef and
createMediaElementSource to cache one MediaElementAudioSourceNode per
HTMLAudioElement in a WeakMap and reuse it across effect reruns, including
StrictMode remounts. Ensure cached nodes remain connected to the active
processing graph without recreating them or leaving elements attached to closed
contexts; preserve the existing cleanup and fallback behavior.
- Around line 175-179: Update the preparePreviewAudioTrack flow in
VirtualPreview so rejected IPC calls are handled and still mark audio probing
complete. Add a rejection path alongside the existing success handler that
clears or preserves the appropriate supplemental audio source, calls
setAudioProbeComplete(true), and prevents an unhandled promise rejection.
- Around line 218-237: Ensure the mastering-parameter effect also runs after the
audio graph is created, rather than relying on the ref update to trigger it.
Track graph creation with state and include that state in the effect
dependencies, or extract the parameter assignments from the effect and invoke
that function immediately after graph creation while preserving the existing
settings behavior.
- Around line 757-780: Stabilize the audio element ref callbacks in
VirtualPreview by wrapping the primary and supplemental ref handlers with
useCallback. Preserve assigning both the corresponding audio ref and state
setter, and ensure dependencies include the referenced setters and refs so
callbacks do not change on each render.
In `@src/i18n/locales/ar/settings.json`:
- Around line 56-59: Translate the English values for layout.webcamFraming,
layout.webcamCropZoom, layout.webcamCropX, layout.webcamCropY, and every entry
in the audio group within the Arabic settings locale, while preserving valid
JSON and the existing key structure. Verify all 13 settings locale files contain
these keys and run the provided i18n check to confirm no required values are

Exact-head readiness checkpoint: b12d135 is rebased onto canonical main fa9719a (0 behind / 4 feature commits ahead). Fresh focused editor tests passed 19/19; app and test TypeScript checks passed; changed TypeScript/TSX files passed Biome; native compositor tests passed 137/137. The independently found CRLF diff hygiene issue was normalized only in the 14 added CSS lines, and the exact branch diff now passes git diff --check. Independent implementation review returned GO. Landing remains externally blocked by upstream maintainer approval and zero-job Actions; no merge was attempted. The exact branch remains remote-backed and its local task worktree/cache was removed. |
The editor's auto-master chain could not be reproduced in the preview, so the file a user exported was not the one they had just approved by ear. The preview plays the untouched source file, seeked. The export runs `finish_audio` on the assembled timeline — trimmed, speed-adjusted, concatenated. Two of the four auto-master stages diverge across that gap by construction: the high-pass and the compressor carry state across cuts on one side and not the other, and Chromium's DynamicsCompressorNode is not the hand-rolled peak compressor in audio.rs to begin with. The fourth is worse still — the RMS/peak makeup is a single scalar (up to x4) measured over the whole assembled programme, which the preview never holds and which changes with every trim. So the preview applied a filter and a compressor it could not match and skipped a normaliser it could not compute. It also shipped enabled by default, which meant every project ever recorded would have come out at a different level on its next export without the user touching anything — while the Rust side defaulted the same flag to false. Keep what is parity-safe by construction and drop the rest: - Sync offset and output gain stay. A whole-sample delay and a linear gain land identically on the source file and on the assembled timeline; the preview's GainNode now uses the same `10 ** (dB / 20)` scalar `finish_audio` applies, and a test pins that identity. - The preview graph loses the BiquadFilterNode and the DynamicsCompressorNode and becomes source -> gain -> destination. It also no longer tears the whole graph down when one element fails to route: once createMediaElementSource has run for an element, `volume` no longer reaches the output, so disconnecting everything muted the preview instead of degrading it. - One range instead of three. The sliders, the store and `finish_audio` all clamp to +/-500 ms and +/-12 dB, exported as AUDIO_OFFSET_MS_LIMIT / AUDIO_GAIN_DB_LIMIT. - SceneAudio drops `auto_master` and gains per-field serde defaults, so a payload from a build that predates a field degrades to "neutral" rather than failing the whole scene. - sceneDescription.test.ts asserts the payload exposes offset and gain and nothing else, so a future stage cannot be added here unnoticed. Webcam crop, "Add to timeline" and the preview sync loop are untouched.

Thanks for this — the webcam crop and the Add to timeline action are exactly the kind of finishing controls the editor was missing, and the TS→Rust crop parity work ( I've rebased the branch onto WhyThe PR describes the mastering as "applied consistently in preview and native export". I went to verify that and it doesn't hold — and it can't, with this architecture:
The last one is the blocker, and it isn't a matter of porting the code. That makeup is a single scalar measured over the assembled timeline — after trims, speed regions and concatenation. The preview plays the untouched source file, seeked; it never holds that programme, and the scalar changes with every trim. So it cannot be reproduced live short of rendering the export's audio assembly in the renderer. The filter and the compressor have a milder version of the same problem: they carry state across cuts on the export side and not on the preview side. Those two could be brought to near-parity ( Two things pushed me from "needs work" to "remove":
What I kept, and why it's provableSync offset and output gain stay. A whole-sample delay and a linear gain are the only operations that land identically on the source file and on the assembled timeline:
The preview graph is now A few things I fixed while I was in there:
On the descriptionOne correction for the record: the first bullet claims the PR draws the audio waveform in the timeline. That's been on If you want the mastering backIt's a good feature and I'd take it as its own PR, on these terms:
Residual divergence at clip boundaries (filter state and compressor envelope crossing a cut on one side only) is fine as long as it's documented rather than claimed away. Happy to review that one whenever you get to it. Thanks again for the crop work — that part is landing as you wrote it. |

Make the offset-bound assertion observable.
The two-sample input becomes silence for both a 500 ms delay and a 9,999 ms delay. The assertion does not prove that offset_ms clamps to 500 ms.
Use a buffer longer than AUDIO_OUTPUT_SAMPLE_RATE / 2 with an impulse. Assert that the impulse appears exactly at the 500 ms sample index.

Serialize rapid asset drops before calling insertClipAt. handleDropAsset captures the same clips.length, and insertClipAt reads that stale document before each save. Concurrent saves can place both clips at one index or overwrite the first clip. Read the document inside a sequential queue and compute the append index there.

Resolve audio offset in timeline time.
finish_audio shifts audio after speed adjustment and clip concatenation. The preview subtracts the offset directly from active-source time.
At 2× speed, a 500 ms export delay becomes a 250 ms preview delay. At a clip boundary, delayed or advanced audio can belong to the previous or next asset, but the preview routes only the active asset.
Map virtualTimeSec - offset back to the required timeline clip and source time. Keep the required audio source routed across clip boundaries. Add coverage for non-1× speed and cross-asset boundaries.

resolveAudioPreviewTime and its callers to interpret offsetMs in timeline time,
converting it according to the active clip’s playback speed before deriving
source time. Route the required audio source across adjacent clip boundaries
when the offset places playback in a previous or next asset, and preserve
correct clamping and shouldPlay behavior. Add coverage for non-1× speeds and
cross-asset boundary cases.

What changed
Why
The editor exposed no waveform or practical way to correct residual sync, clean up voice audio, or crop a webcam feed. Those are core finishing controls for a screen recorder and should be fast enough to use without external editing software.
Impact
Users can see where speech occurs, nudge audio without changing duration, master voice quickly, and reframe webcam footage while keeping preview and export behavior aligned.
