Hello and thank you for this very promising application.
I'd like to ask if there is (or will be) a feature to NOT re-encode mpeg video files that are already compatible with the current project.
I.e.: if a video clip is 720×576, 25fps, ac3 audio, in a PAL 2mandvd project, to have the option to just use it to generate the VOB without re-encoding.
Such files are generated by many camcorders. Such feature will help to reduce the processing time plus will not degrade the video quality.
Thank you for your time!
