Changelog

New features, improvements, and fixes across the Cap desktop app, web, mobile, and browser extension.

Web

Translated Captions

Captions are no longer stuck in the language you spoke. Viewers can translate captions on the share page player and watch in the language they prefer.

Features

  • Caption translation - Pick a language from the player and captions are translated automatically.
  • Context-aware output - Translations use the surrounding transcript for better phrasing than line-by-line conversion.
Web

One-Command Self-Hosting

Self-hosting Cap is now a single command. A new Docker Compose setup brings up the full web app, database, and storage in one go, with rewritten self-hosting docs to match.

Improvements

  • docker compose up - One command starts everything Cap needs to run on your own infrastructure.
  • Clearer docs - The self-hosting guide has been rewritten with the new setup, including configuration and upgrade notes.
Desktop0.4.5

Camera Only Mode, Faster macOS Capture & Better Screenshot UX

Show release notes
  • Camera Only Mode — Record video using just your camera. This mode can be toggled directly from the main window for quick, focused video capture. Both Studio and Instant Mode supported.
  • More reliable decoding and seek behavior — Added FFmpeg software fallback when hardware decoding fails, improved AVAssetReader end-of-file handling, and tuned decoder timeouts for slow seeks and initial playback.
  • Smoother exports and playback stability — Editor preview now pauses during export, keyframe distribution and frame iteration were improved, and GPU buffer resizing is more robust to reduce stalls.
  • Lower-overhead macOS frame processing — Introduced pooled pixel buffers and a dedicated copier for screen capture, then refactored frame scaling around the pool for more efficient processing.
  • Improved audio timestamp and drift handling — Reworked timestamp/drift logic in the recording and MP4 pipelines for more stable long-running audio-video sync.
  • Cleaner screenshot workflow — Target selection overlays are now hidden before capture, hidden overlays no longer block clicks, and screenshot notification audio behavior was refined.
  • Better multi-display overlay focus — Improved focus and positioning logic for target-selection overlays across multi-monitor setups.
Desktop0.4.4

Instant Mode Reliability, Prewarmed Target Picker, Multi-Display Fixes

Show release notes
  • Instant mode fixes — Fixed frame scaling when display dimensions change mid-recording on macOS, clamped crop bounds to prevent negative coordinates on Windows, and ensured monotonic frame timestamps in the MP4 encoder.
  • Prewarmed target picker — The target selection overlay now loads in the background so it opens instantly when you click Record Display, Record Window, or Record Area from the main window or tray menu.
  • Multi-display window positioning — The main window, camera preview, and recording controls now appear on the display containing your cursor instead of always defaulting to the primary display. The recording controls bar also follows your cursor when moving between monitors.
  • Search and pagination for recordings — Added search fields to the recordings and screenshots settings pages, along with pagination for large libraries.
  • Tray menu screenshot support — The tray menu now includes a "Take a Screenshot" option and shows mode-aware labels when in screenshot mode.
  • Screenshot editor reliability — The screenshot editor now loads images more reliably with proper retry handling and correct path resolution for .cap project files.
Desktop0.4.3

Video Import, Advanced Compression & Smoother Animations

Show release notes
  • Video import support — You can now import existing video files directly into Cap for editing and sharing. Imported videos go through the same studio workflow as recordings, letting you add zoom effects, cursor overlays, and export with Cap's compression.
  • Advanced export compression controls — Added custom bits-per-pixel settings for fine-grained control over export quality and file size. Access these options in the export panel to dial in the perfect balance for your use case.
  • Enhanced cursor and zoom interpolation — Improved spring-based animation system with better critically damped motion for smoother cursor and zoom transitions. Added screen motion blur support for more polished playback.
  • Better audio handling on Windows — Improved audio latency handling with proper Windows support. Resampling errors are now handled more gracefully to prevent export failures.
  • Decoder health monitoring — Improved decoder health checks and cache handling to detect and recover from GPU/decoder issues more reliably during playback and export.
  • macOS window improvements — Windows now properly center on screen and respect focus/activation policies for a more consistent experience.
  • Even dimension fixes — Screen capture and video scaling now ensure dimensions are always even, preventing encoding issues with certain video codecs.
Desktop0.4.2

Simplified Audio Timestamps, Pause/Resume Fixes & Preset Management

Show release notes
  • Simplified audio timestamp generation — Replaced complex drift tracking with sample-based timestamp generation for more reliable and predictable audio timing. This eliminates edge cases with clock drift detection and produces cleaner, more accurate audio synchronization.
  • Improved pause/resume handling — Added shared wall clock pause tracking that correctly accounts for paused time in both video and audio pipelines. Recordings now seamlessly continue with accurate timestamps after pausing and resuming.
  • Better frame recovery during playback — Increased fallback distance for frame cache lookups, especially near the end of videos. Playback now handles missing frames more gracefully by using nearby cached frames rather than failing.
  • Preset management improvements — Added ability to clear all presets and improved configuration default handling. Default cursor mode now uses raw positioning for snappier cursor movement.
Desktop0.4.1

Export Resilience, Audio-Video Sync & Silent Video Support

Show release notes
  • Improved export resilience — Exports now retry failed frame decodes up to 3 times with exponential backoff, and can recover from intermittent GPU/decoder hiccups. If a frame fails completely, the previous valid frame is used to prevent gaps. Timeout handling is now more forgiving, waiting for up to 3 consecutive timeouts before aborting.
  • Better audio-video timestamp sync — Improved resync logic handles large timestamp jumps (such as those caused by system sleep/wake) by automatically resyncing to wall clock time. Clock skew compensation is now more robust with proper floating-point accumulation.
  • Timestamp pipeline overhaul — Recording timestamps now propagate correctly through the entire capture and audio pipeline from the very first frame, improving sync accuracy from the start of recordings.
Desktop0.4.0

Screenshot Mode, Local Captions, New Editor Tracks & Recoverable Recordings

Show release notes
  • Screenshot Mode — Capture and edit screenshots with a dedicated editor. Includes shapes, text annotations, sensitive masking, backgrounds, padding, and more. Export or share with a single click.
  • Local caption generation — Generate captions directly on your device using Whisper, with support for many languages. Fully customizable styling (font, size, color, background, position) and SRT export.
  • New editor track types — Text overlays, Sensitive Mask, and Highlight tracks give you more creative control over your recordings.
  • Overhauled recording picker — Brand new target select overlay makes it easier than ever to pick your recording source.

  • Circle cursor — New mobile simulator cursor option for showcasing app demos.
  • Faster editor playback — Major performance improvements including WebGPU rendering, optimized YUV conversion, and hardware decoder support on Windows. Longer videos now scrub and play back much smoother.
  • Preview quality options — Quarter and Half preview quality options for faster playback on slower systems.
  • Improved audio-video sync — Post-recording sync calibration, drift correction, and input latency estimation on macOS for tighter sync.
  • Recording hotkeys — New pause/resume hotkey and cycle recording mode hotkey. Tray menu now shows mode selection with dynamic icons.
  • Better device support — Lots more webcams and microphones are now supported, with improved device detection and permission flows.
  • Redesigned export page — New export UI with live preview, render time estimates, and frame-accurate cropping via a timeline slider.
  • Windows reliability — Hardware compatibility checks, encoder health monitoring with automatic fallback, Media Foundation decoder with D3D11 interop, and Windows fragmented M4S muxer support.
  • Bug fixes — Fixed memory leak while streaming, split action now respects segment speed, and recordings now use human-readable project names instead of UUIDs + lots more quality of life improvements.
