Cinefx is an open - source AfterEffects-type application although I haven't gotten it to run and I doubt it's nearly as sophisticated as AE, especially for what we do with AE. The same issue is with FCP and Samplitude. We need to be able to import/export OMF files. We need professional color-correction tools. We need to be able to put effects on segments or "objects" rather than on entire tracks.
