Die Videobearbeitung gilt als Herausforderung für Hard- und Software. Bei den Linuxtagen wurde LiVES erstmals vorgestellt.
LiVES ist ein auf offenen Standards basierendes Framework, das den Schnitt, aber auch Echtzeitbearbeitung von Audio und Video (zB für VJing) ermöglicht. Jede beliebige Kombination von Input/Output in 50 Formaten ist möglich, sogar das Ausspielen auf animierte gifs ;-/ Das werden wir uns wohl näher anschauen müssen!
Einige der Features:
- Loading and editing of most video formats (via mplayer decoder).
- Smooth playback at variable frame rates, forward and in reverse.
- 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).
- 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
- Support for RGB24, 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 even animated GIF and PDF!)
- Resampling of video (time stretching) to any frame rate (1 to 200 fps); 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.
