ReplayMac

ReplayMac is a macOS menu bar instant-replay clipper.

It continuously buffers recent screen/audio capture and saves the last N seconds to an MP4 when triggered. Recording and save state stay visible in the menu bar so you always know what the app is doing. Features

• Instant replay — Continuously buffers the last N seconds (15–300) of screen and audio; save retroactively with a click or hotkey.
• Dual display support — Capture one or two monitors, saved as a side-by-side composite or as separate files.
• Hardware-accelerated encoding — HEVC or H.264 via VideoToolbox, with configurable resolution, frame rate, and bitrate.
• System audio + microphone — Capture all apps, no audio, or one selected app. Mic and system audio merge into a single track by default; optionally keep as separate tracks inside the MP4.
• Live audio level meters — Real-time RMS-based level meters for system audio and microphone in audio settings.
• Ring buffer memory management — Configurable memory cap (256 MB–4 GB) shared across all replay buffers, with automatic eviction under memory pressure.
• Extended replay buffer — Optionally roll 5, 10, or 30 minute replay windows to disk, with SSD write and disk usage warnings before enabling.
• Six configurable hotkeys — Save clip, toggle recording, save last 15s, save last 60s, save extended replay, open clip library.
• Clip library — Browse, preview, trim, export, or export as GIF; rename, tag, favorite, and batch-act on multiple clips at once.
• Clip sharing — Open the macOS share sheet or copy a clip file for pasting into another app.
• Clip organization — Search clips, mark favorites, add display names, tags, and notes.
• Storage cleanup — View total library size and move non-favorite clips to Trash by age or in bulk.
• Capture profiles — Save named video/audio/buffer configurations and switch between them on demand.
• Customizable file-name templates — Name clips with {app}, {date}, and {time} tokens, with a live preview in Settings > General.
• Quality presets — Performance, Quality, Ultra, and Custom modes that tune resolution, frame rate, and bitrate together.
• Live settings — Capture, encoding, and audio changes apply while recording; no restart required.
• Reliable save flow — Preflight checks block saves when not recording, while the buffer is filling, or when disk space is too low.
• Clear menu bar status — Live badge shows recording state, buffered time, and save progress. Last saved clip is one click away from the menu.
• Notifications — Optional sound and banner on save, with Open and Reveal in Finder actions on the notification; operational alerts for failures and capture events.
• Launch at login & auto-start — Optionally begin recording automatically on login.
• Update availability check — Checks GitHub Releases on launch and shows a download link in the menu when a newer version is available.
