Isocast 0.0.5 Alpha
Isocast 0.0.5 for Apple-silicon Macs (macOS 14+). If you're on 0.0.4, Isocast › Check for Updates… installs it. Your camera, microphone and screen permissions carry over.
Switch from OBS
- Import from OBS on first launch: Isocast finds your OBS scene collections and brings them in with their profile's settings, then Optimize picks settings for Recording, Streaming or Both on your Mac.
- obs-websocket v5: turn it on with
isocast websocket enableand tools built for OBS (Touch Portal, community Stream Deck plugins, obs-websocket scripts) drive Isocast. - Replay buffer: save the last 30 seconds (up to 5 minutes) on a hotkey.
- Virtual camera: Isocast shows up as a camera in Zoom, FaceTime and other apps (macOS asks you to allow it once). Remove it any time from the camera popover.
- Multistream: stream to several destinations at once from one encode.
Edit in Isocast
- The editor window (Window › Editor, ⌘E): every ISO track of a take on one timeline. Trim, split, switch angles, and export frame-accurately without touching the originals.
Recording
- Crash-safe takes, on by default: if Isocast or your Mac crashes, you lose about half a second, and the files are repaired on the next launch.
- Per-ISO audio: choose each ISO file's audio (camera + mic, screen + desktop audio).
- Per-app audio: record one app's sound, or everything except some apps (macOS 14.2+).
- ISO capacity warnings: Isocast tells you when your Mac can't keep up with your ISO files, with a one-click fix, and picks sizes that fit.
- Streaming after you start recording no longer costs ISO frames, and the program and audio stay clean at your Mac's limit.
- VP8 WebM stingers (older OBS stingers) play without converting.
Fixes
- After an update, Isocast replaces an older engine still running (never mid-take).
- A microphone whose driver stops answering no longer blocks recording for minutes.
- Faster CLI commands; a hard-to-hit crash when listing silent media as ISO audio; macOS prompts now say "Isocast Engine".
