Thank you. Yet, Unix in general, has been used; before Dos, windows, mac, etc. to edit video (cut and append) sync audio and video, or re make (at night) using different Codecs, a new updated video, ready by morning. What did they use? I want to use Calibre in 7.2 for my library, and it is not here. (off the track, sorry) - Using VDub vs Unix, Linix, Knoppix; you would think, someone, would have shared; a set of video tools, that are both useful and accurate - And, - have been around along time. Thanks. Ps. I tried to install VDub as a wine app but was not successful.
