LiVES – VJ and Video Editing system

LiVES is a Video Editing System. It is designed to be simple to use, yet powerful. It is small in size, yet has many advanced features.

LiVES mixes realtime video performance and non-linear editing in one application. It lest you start editing and making video right away, without having to worry about formats, frame sizes, or framerates.

It is a very flexible tool which can be used by both VJ’s and video editors – mix and switch clips from the keyboard, trim and edit your clips, and bring them together using the multitrack timeline.

Platform

• Stable and well tested core.
• Runs on at least x86, amd64, ppc and xbox/x86.
• The LiVES audio/video platform is now custom extendable through RFX plugins
• Allows quick and easy prototyping of new tools, utilities, effects, transitions and more, using the included RFX builder window.
• Plugins can be written in Perl.
• Will scale for high/low end hardware. Can be split into client/server components
• Control every function in LiVES remotely using OSC protocol.
• 100% original, non-proprietary code.

Video

• Loading and editing of most video formats (via mplayer decoder).
• Smooth playback at variable frame rates, forward and in reverse. Display framerate can be controlled independantly of playback framerate.
• Cut and paste of frames within and between clips.
• Saving/re-encoding of clips, selections, and individual frames.
• Lossless backup/restore.
• Streaming input and output.
• Real time blending of clips (chroma and luma blends).
• Can handle in/out streams in yuv4mpeg format. Streams can be piped from stdout into other applications.
• Supports fixed and variable framerates. Playback rate can be smoothly adjusted independant of display rate.
• Ability to ‘scratch’ with video – that is to move smoothly backwards and forwards through it, and to record yourself doing so.
• Playback can use LiVES’ own internal player, there is also a high performance fullscreen SDL playback plugin.
• Internal support for RGB24, RGBA32, YUV420 (TV), and UYVY palettes; horizontal chroma subsampling is implemented.
• Ability to edit many filetypes and sources including remotely located files (with mplayer/ffmpeg libraries), and directories of images.
• Real time capture/recording of interactive (via mouseclicks) external windows.
• Encode to any of the 50+ output formats which are now supported (e.g. mjpeg, mpeg4, mpeg1/2, VCD, SVCD, DVD, ogg/mp4 ogm, Matroska mkv, dv, swf, Ogg Theora, Dirac, MNG, Snow, xvid, and animated GIF and PDF).
• Encoder formats can be extended through the encoder plugin API.
• LiVES will suggest the best settings for saving to each format.
• Resampling of video (time stretching) to any frame rate (1 to 200 fps – accurate to 8 decimal places); option to auto-resample or speed up/slow down between clips.
• Ability to instantly alter the playback speed of video and audio independently.
• Rotation, resizing and trimming of video clips.
• Deinterlacing, subtitle removal.
• Instant saving/loading of clips for performances/presentations.

Audio

• Can load mp3, ogg, mod, xm and wav files.
• LiVES can also load tracks directly off CD to use with your video (using cdda2wav).
• Ability to save audio selections, and append audio.
• Sound can be trimmed to fit video selections.
• Cutting and pasting of audio within and between clips.
• Resampling of audio (rate, channels, sample size, signedness and endianness); audio is auto-resampled between clips.
• Supports (auto)inserting of silence and deletion of audio sections.
• Able to record from any external audio source.
• Fade in/fade out feature for clips.
• Audio speed and direction can be smoothly adjusted; both in real time and when rendering.

Effects/Transitions

• Many effects, including random/targeted zooming, panning of video, colour cycling and colorisation/colour filtering.
• Merging/compositing of frames is possible: e.g. frame-in-frame, fade in/out and transparency.
• Real time previews as the effect is processing.
• Support for the LiViDO effect plugin architecture which will allow sharing of realtime effects with other applications. Experimental support for this framework is already included.
• Use real time effects to blend clips together, regardless of frame size or fps. Luma and chroma blending are currently supported.
• Multiple real time effects are now possible during playback (VJ mode), these can also be rendered to frames.
• Effects and transitions are now fully customisable using the RFX builder window.
• Effects/blends can also be applied to incoming streams in real time.
• Dynamic loading of effects.

Multitrack

• Multitrack window with drag and drop.
• Intelligent screen organisation – shows you only the information which is relevant, no more and no less.
• Support for an almost limitless number of tracks and effects.
• Rapid rendering – resize/resample and effects apply done in a single pass.
• Tracks can be laid out entirely with keyboard, or with mouse, or a combination of both.
• Multitrack settings can be targetted for a specific encoder, or generic.
• Layouts can be saved and reloaded.
• Audio blocks can be timestretched and even reversed.
• Non-destructive editing, with multiple levels of undo/redo.

Extras

• Full crash recovery.
• Simple and intuitive menu layout.
• I18N text support. Translations into French, Czech, German, Japanese and Portuguese are included.
• Support for audio output through jack.
• Jack transport support (master or client.
• RFX builder allows rapid prototyping of new effects, transitions utilities and tools
• Midi sequence synchronisation (start/stop).
• Can load single images or directories of images in numerical order and assemble them into videos or slideshows.
• Ability to play music through xmms (including random selection of tracks).
• Shuttle controls for firewire cameras/recorders. Can grab from DV and HDV formats.
• Can stream out (on stdout) using yuv4mpeg format.
• Project files (clips and layouts) can be exported and imported.
• Toys.
