Here is a couple more video editors that you may want to look into. Kdenlive kde-apps/kdenlive Avidemux media-video/avidemux The first one is KDE based. Last time I used it, it was large but had lots of fancy stuff it could do. The second one has both a gtk and qt based version. I'm guessing that is controlled by USE flags. I seem to have both of them here. :/ Maybe one of those will help. Dale :-) :-)
