Bay Effects 0.2.4

2026-10-20T00:00:00Z

Initial release.
Roto Brush separates a subject from the background and carries the matte from frame to frame. In Settings ▸ Roto Brush you can switch to MobileSAM, which is downloaded when you ask and runs on your Mac.
Face tracking keys a mask to a face, or keys every eye, brow and mouth point into the layer. MediaPipe Face Landmarker is available as its trained model.
Project, Composition, Timeline and Effect Controls panels laid out the way After Effects lays them out, with the Graph Editor, expressions, 306 effects and layer styles, and 3D layers with cameras and lights.
Render H.264, HEVC, ProRes with alpha or WebM, or export Lottie, with no FFmpeg to install.
Every action is a command, open to the bay-effects command-line tool and an MCP server, so an agent can build a composition in the open project. One disk image for Apple silicon and Intel Macs, with Bay Effects and its tool inside.

Initial release.
Transcribe footage on your Mac with Whisper, then cut by selecting words in the Text panel, or remove filler words and long pauses in one step.
Turn a transcript into captions with the spoken word highlighted, and burn them in or save them as SRT, WebVTT or SCC.
Click an object in the Program monitor to get a mask that follows it from frame to frame. Auto Reframe turns a sequence into 9:16, 1:1 or 4:5 and keeps the subject in frame.
Generate narration with a Gemini voice and music with Lyria through your own Google account, after Bay shows what it will send and you agree.
One disk image for Apple silicon and Intel Macs. The command-line tool is called bay and comes inside the app: choose Bay ▸ Install Command Line Tool… to use it from Terminal, and bay mcp lets an agent drive the editor.
