Release notes

Videorc 0.9.78 Alpha 1

The Windows pilot catches up from 0.9.72 to 0.9.78. The biggest one for anyone using a capture card: Videorc was recording 1080p and enlarging it to fill a 4K canvas, because cards run at 29.97 frames per second and a 30 fps request rejected them by three hundredths of a frame. Also here — recordings survive a lost microphone, frozen recordings get reported instead of passing silently, the sidebar shows keyboard shortcuts only while you hold Ctrl, and scrollbars lost their heavy backgrounds.

This release is not currently available for public download.

All releases

Six releases of fixes land on Windows

  • Capture cards record at their native resolution again instead of a 1080p image stretched to fit — 4K recordings through a Cam Link or similar were soft and now are not.
  • Losing a microphone mid-recording no longer ends the session on the native audio path; the recording continues and pads the audio with silence.
  • A recording whose frames froze is now flagged after capture instead of passing quietly as fine.
  • The microphone meter works before you record, so you can check the mic without starting a session.
  • Hold Ctrl to see the sidebar's keyboard shortcuts; release it and they fade away.
  • Scrollbars are a faint thumb with no track, Settings lost its blank gap, and the co-host no longer appears during recording-only sessions.

What Windows gets in this jump (0.9.72 → 0.9.78)

  • Capture-card resolution (0.9.77). The camera format chooser required an exact frame-rate match, and capture devices advertise the fractional NTSC rates broadcast video uses. A 2160p mode at 29.97 missed a 30 fps request by 0.03, was discarded, and lost to 1080p60 — so 4K sessions captured 1080p and upscaled it. Now tolerant to one frame, and resolution-covering formats win. This is shared code, so the fix arrives on Windows exactly as on macOS.
  • Microphone loss continuity (0.9.78). A lost microphone pads the audio track with silence and the session continues, with a durable warning. See the limitation below for what this does not yet cover on Windows.
  • Honest recording checks (0.9.73). The post-recording check now uses the pipeline's own counters, so a majority-frozen recording is reported rather than passing as clean. Per-source frame-freshness counters are in every support bundle.
  • Interface (0.9.76–0.9.77). Shortcut hints reveal only while Ctrl is held; the sidebar is narrower and the header simplified; scrollbars have no track; Settings lost its blank gap; the co-host is streaming-only.
  • Reliability (0.9.74–0.9.75). Deterministic encoder teardown at session end, per-session capture ownership, and fail-closed recording analysis.

Known limitation on Windows

The microphone-loss work covers the native audio path. Windows DirectShow receives the silence-padding policy but does not yet use the native source-loss monitor, so a clean end-of-stream there raises no microphone-input-lost warning, and a fatal DirectShow driver error can still end the capture process. This pilot was not verified on physical Windows hardware.
