A player and exporter for video and audio, by Jesper GB Henriksen.

Open a file, play it, set an in and out point, crop the picture, and for audio files change the level over parts of the waveform. Then write a new file containing exactly that. One clip at a time: no timeline, no layers, no project file.

New in 0.3.0

MKV plays directly. No converting the whole movie first — it opens and plays, and conversion happens only when you export. Export a selection or the whole file to MP4 or MOV, with H.264, HEVC or the supported ProRes options. No separate VLC, FFmpeg, Homebrew or codec installation is needed; the decoder ships inside the app.

GIF export. Size and frame-rate settings, silent, looping, and a warning before exporting a selection longer than 45 seconds.

Timeline zoom. Pinch, or use + and −. Fit restores the whole movie. The overview below the timeline lets you pan around a long file without moving your trim or your playback position.

MP3 export sits alongside WAV, AIFF and M4A for audio files.

Not supported for MKV in this version

Subtitles, LUT preview, frame grabs, image-sequence export and audio-only export. HDR, rotated and anamorphic MKV video exports are rejected. HDR GIF export is unavailable.

Install

Quit any running copy of Kipowi, open the disk image and drag Kipowi to Applications. If you are replacing an older version, keep a copy of the old app first.

Requires: macOS 14 or later. Universal for Apple silicon and Intel. Signed with a Developer ID certificate, notarised by Apple and stapled, so it opens without a Gatekeeper warning even offline.

Source code

Kipowi-0.3.0-Sources.tar.xz below is the matching source archive for the open-source media components the app bundles — VLC, VLCKit, FFmpeg and LAME — with the patches, dependency sources and build recipes. You do not need it to run Kipowi. It is here because the licences of those components require the corresponding source to be available beside the binary. Third-party notices are in the app under Kipowi › Media Component Licenses.
