DubEdit
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...
