Summary

Manual end-to-end pass on installed v1.10.0-rc.3 (CI-built NSIS artifact, About reports 1.10.0-rc.3), Windows 11, driven with computer-use. One results-log row — no other changes.

Verdict: Pass — 3 minor defects; caption rendering not covered.

Two corrections. Earlier versions of this PR reported (a) a blocking "pause does not pause the capture" defect and (b) local transcription as broken. Both were wrong, both were caught by the maintainer, and both are retracted below and in the row itself.

Pause works — retracted

createdAt 20:25:52.208
File finalised 20:30:56.754
Wall-clock elapsed 304.55 s
File duration 286.333 s
Difference 18.21 s — exactly the paused interval

Capture was genuinely suspended. The original comparison used a timer read before the stop click; with ~20 s tool round-trips that gap was my own latency. The packet count cited as corroboration was never evidence — a file is continuous 60 fps whether or not capture was suspended.

Local transcription works, on GPU — retracted

Relaunching with stdout/stderr captured and importing an asset that actually carries an audio track:

[whisper-stt] boot: model=…\whisper-ggml\ggml-small-q8_0.bin host=127.0.0.1 port=64720 threads=16
ggml_vulkan: 0 = NVIDIA GeForce RTX 4070 Ti | fp16: 1 | matrix cores: NV_coopmat2
[whisper-stt] model loaded; backend=whispercpp-vulkan
[stt] done on whispercpp-vulkan: 1 chunk(s), 15.0s audio in 0.1s (0.01 rtf, 106.8x real-time)

The server spawns, binds the GPU and transcribes at 106.8× real-time.

The three minor defects

  1. Misleading transcription error. On an asset with no audio track the captions pane reports "Failed to fetch" — it reads as a network failure and cost this run an hour hunting an STT server that was never involved. It should say the media has no audio.
  2. Three unreadable project files. listProjects fails on one ZodError (transcript.segments[0].endSec must be greater than or equal to startSec, repeated across segments, words, transcripts[0]) and two SyntaxError: Unexpected non-whitespace character after JSON — truncated or double-written project JSON, skipped silently in the UI.
  3. HUD language menu ignores Escape (two presses, foreground confirmed via GetForegroundWindow) and outside clicks inside the HUD; only re-clicking the button dismisses it. The blur dismissal shipped in this RC (54e12706) does work.

Still not covered — the rc.2→rc.3 delta

The Position section is present with exactly the model the cherry-picks describe: Bottom/Top, "Long captions grow upward — the bottom edge stays put", Distance from bottom defaulting to 1.5 %, Left/Center/Right. Where a caption actually lands was not measured — the only transcript obtainable here came from a 300 Hz sine and produced one line that never surfaced while scrubbing. Someone with a real spoken-audio recording should run the caption sections before promote.

What passed

Capture is sound on two takes — fragmented MP4 with mfra on the stop, exact packet-to-duration ratios, clean decode, both sidecars, no dropped frames over 4 min 46. Export honours 720p/30 from a 1080p60 source and matches the source duration; composition verified on a frame extracted at full resolution. Launch, HUD visibility, tray-layout toggle, HUD drag, source selection, record→editor, single-instance relaunch, About, and the content-protection flag (confirmed in stderr) all pass.

Environment notes for the next runner

Parsec's elevated always-foreground window makes tray refocus untestable and blocks clicks whenever the app loses focus; the Microsoft Store package shadows the NSIS install in request_access; the HUD drag gate keys on the pointer staying inside the HUD's own window. Screenshots do not interrupt a recording — hypothesis raised and disproved by experiment.

Summary by CodeRabbit

  • Documentation
    • Updated Windows 11 validation results for release candidate v1.10.0-rc.3.
    • Confirmed pause/resume timing, capture, export, GPU transcription, content protection, and manual caption verification.
    • Removed the previously reported language-menu dismissal issue after further investigation.
    • Documented remaining issues: misleading no-audio transcription errors and silently skipped malformed projects.
    • Noted that automated caption-rendering coverage remains untested.

One defect that should block the promote: pause freezes the HUD timer and turns
the indicator amber, but wgc-capture keeps writing. The file is 286.333 s against
a 04:25 timer, and 17,180 video packets is exactly 286.333 x 60 - uninterrupted
60 fps straight through the paused interval. Neither sidecar carries a pause
marker, so nothing downstream can excise it and the editor opens the project at
4:46.3. Whatever the user does while "paused" ships in the video.

Capture and export are otherwise clean on this build. Two takes, both fragmented
with mfra on the stop, exact packet-to-duration ratios, no dropped frames over
4m46. Export honours 720p/30 from a 1080p60 source and matches the source
duration to the millisecond.

A minor one alongside: the HUD language menu ignores Escape and outside clicks,
though the blur dismissal shipped in this RC (54e1270) does work.

The gap is the part worth reading twice. Transcription fails with "Failed to
fetch" and the local STT server never spawns, so captions could not be turned on
at all - which means the eight caption anchoring commits that are the whole delta
from rc.2 to rc.3 are untested. The row says so rather than implying coverage.

Also recorded: Parsec's elevated always-foreground window makes tray refocus
untestable, the Store package shadows the NSIS install in request_access, and the
HUD drag gate keys on the pointer staying inside the HUD's own window. Those cost
hours here and should not cost them again.

The maintainer tested pause by hand and it worked. It does. The wall clock
settles it: createdAt 20:25:52.208 against a file finalised at 20:30:56.754 is
304.55 s elapsed for a 286.333 s file - 18.21 s shorter, exactly the pause. The
capture was suspended.

The first draft compared the file duration against a timer read BEFORE the stop
click. Tool round-trips here run ~20 s, so that gap was my own latency, not the
pause. The packet count I offered as corroboration was never evidence either: a
file is continuous 60 fps whether or not capture was ever suspended. The rule
that survives is in the row now - measure against wall-clock elapsed, never
against the last timer you happened to screenshot.

Verdict goes from Fail to Pass with one minor defect, the language menu ignoring
Escape, which was tested directly and stands.

The STT paragraph is corrected too. The packaged whisper-stt-server runs fine by
hand and asks for --model, so packaging is not the cause and the row no longer
implies it. Two candidates remain unseparated: the asset had no audio track, and
"Failed to fetch" comes from a call the code reading did not locate, since the
local-file caption path uses IPC and OPFS rather than fetch. It worked in rc.2.
That one wants captured stderr, not more inference.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The maintainer said STT is packaged and worked in rc.2. It works in rc.3 too.
Relaunching with stdout/stderr captured and importing an asset that actually has
an audio track produced:

  [whisper-stt] boot: model=...\whisper-ggml\ggml-small-q8_0.bin port=64720
  ggml_vulkan: 0 = NVIDIA GeForce RTX 4070 Ti
  [stt] done on whispercpp-vulkan: 15.0s audio in 0.1s (106.8x real-time)

So the local server spawns, binds the GPU and transcribes. What actually
happened in the first attempt is that the asset had no audio track at all -
system audio and mic were off for that take - and the captions pane reports that
case as "Failed to fetch". That message is the defect: it reads as a network
failure and cost this run an hour hunting a broken STT server that was never
involved.

Two more finds from the same stderr. listProjects cannot read three saved
projects: one ZodError where transcript endSec < startSec across segments, words
and transcripts[0], and two SyntaxError on truncated or double-written JSON.
They are skipped silently. And the content-protection flag does log its effect,
which the row now records.

Caption anchoring is present with exactly the model the cherry-picks describe -
Bottom/Top, "long captions grow upward, the bottom edge stays put", 1.5% default
inset. Where a caption actually lands is still unmeasured: the only transcript
obtainable here came from a sine tone. That section still needs someone with a
real spoken recording before promote, and the row says so.

revise the documented expectation accordingly.

wording that the local STT pipeline completed, and explicitly state that
spoken-audio recognition and caption rendering remain unverified.
- Line 453: Update the project-file finding in the checklist to report only that

The maintainer confirms Escape closes the HUD language menu by hand. Claude
Desktop swallows Escape before it reaches the app under test, so the synthesised
press never left the driver - and GetForegroundWindow() returning the HUD does
not rescue the inference, because focus says nothing about a key that was
intercepted upstream.

The companion observation goes with it: the "outside click" I tried landed on
the HUD's own drag handle, which is not outside the popover in any useful sense.

Third false negative in this row, and the third with the same shape - a
measurement artefact of the harness read as app behaviour. The rule is now in
the row: Escape is unusable as evidence from computer-use, and any negative
keyboard result needs a by-hand confirmation before it is written down.

The maintainer ran the caption sections by hand on a real spoken-audio recording
and reports them correct. That was the one thing this automated run could not
supply - the only transcript it could produce came from a sine tone - and it was
the last gap standing between rc.3 and a promote.

Verdict is now Pass with two minor defects, neither of them a release blocker:
the "Failed to fetch" message shown for an asset with no audio track, and three
saved projects that listProjects cannot read and skips silently.
