Audio Video media editor for complex composition
DubEdit allows to edit the Video and the Audio channels of a media though the combination of layers that can be sources (video, picture, parametric shape, audio track, etc...), filters (resize, contrast, transparency, amplify, etc...) and mixers. All filters can be adjusted using parameters that may vary with the time in the media, either based on automatic curves between key frames or driven by formulas like in a spreadsheet. Ergonomic interface (including performance) is an important driver in designing DubEdit: every operation is undoable, all video editing is WYSIWYG. At this time DubEdit has only basic filters and mixers. But it has been designed to be easily extended with new powerful filters and mixers so that it can becomes capable of virtually any possible editing. Only DubEdit Libraries are available on SourceForge. You will find the DubEdit Program on http://dubedit.free.fr/Download (it does not match SourceForge OpenSource requirements)
