Klipp 0.1.0-rc.2

[davidkodar]

The second preview of Klipp, a native video editor for Linux. It fixes problems found since the first preview and adds a few smaller features. Everything in 0.1.0-rc.1 is still here.

New

• Lower thirds have a backing, a shadow and outline by default or a box, so they read over any picture.
• Opening a project says how many media files are offline, and media can be relinked from a whole folder at once.
• Caption translation keeps your names and terms as written, and takes a glossary for recurring terms.
• The assistant (over MCP) can duplicate a sequence, export the timeline, export HDR (HLG or PQ), make proxies, lock tracks and look at frames at full size.
• Picture search and Isolate Object run 4–20× faster on the CPU, and on the GPU when a GPU build of ONNX Runtime is installed (onnxruntime-cuda on NVIDIA); the AI models panel says which each model uses. Both download new model files once, and the old ones are removed. Face detection uses the GPU when ONNX Runtime offers one.

Fixed

• Playback: fast cuts within one file play every frame, layered tracks cut between files use less GPU memory, and stacked stills are no longer uploaded again. Large phone photos show in the viewer. Opening video on NVIDIA no longer risks a hang from the VA-API driver.
• Audio: LV2 plug-ins that passed the sound through untouched now process it; audio plug-ins are applied in exports, loudness measurement and the check, not only while playing; a plug-in that cannot run is refused when it is added, with the reason. The reverb no longer raises the level by about 17 dB. Narration takes keep headroom. The loudness check measures the whole mix.
• Editing: editing a multicam clip keeps every angle where it was cut. A ripple retime keeps linked sound in sync. Shots placed on a beat grid meet with no frame between them. Dissolves and dips onto or off a still need no extra footage. An edit that is refused says why instead of reporting success.
• Captions: made only from the speech you hear (each word once, from the angle whose sound plays, without music or muted clips), with no cue too short to read; larger and higher on vertical frames.
• Titles and grading: every line of a title gets its backing; a lower third can keep inside a pillarboxed shot. Grading measurements read the clip's own picture, and matching a grade stops before it clips the highlights. Lower-frame-rate clips can be conformed by blending or optical flow, and the check notes clips that will judder.
• Export: ProRes, DNxHD and letterboxed exports are composited on the GPU. Exporting without burnt-in captions keeps titles.
• Timeline exchange: FCPXML export writes every picture and sound track and constant speed changes; importing a timeline reuses media already in the project and reports clips that run past their media.

The full list is in the changelog.

Install

• Arch Linux or Omarchy on x86_64, with a working Vulkan driver.
• Download the package from this release and install it with sudo pacman -U ./klipp-0.1.0rc.2-1-x86_64.pkg.tar.zst. Pacman installs the dependencies and replaces rc.1. Or build from source with makepkg -si in packaging/; see the installation guide.

Known limitations

• This is a preview. Expect rough edges, and keep your own copies of work you care about: the project format can still change between previews, and a newer Klipp is not guaranteed to open a project saved by an older one.
• Timeline exchange (OTIO, FCPXML, EDL and AAF in and out, FCP7 XML and MLT in, Kdenlive out) carries the edit: clips, cuts, timing, and markers where the format has them. Grades, most effects and most titles do not come across. An export lists what it leaves out beside the file, and an import reports what it could not bring in.
• GPU support is tested mainly on NVIDIA. AMD and Intel GPUs should work through Vulkan but are not yet validated.
• X11 sessions are less tested than Wayland.
• The plug-in hosts cover subsets of OFX, frei0r, LADSPA, LV2 and CLAP; compatibility varies by plug-in. VST2 and VST3 are not supported.
• There is no signed package repository yet, so updates are installed by downloading the new package; the in-app updater needs that repository.
