Bill, if you want to come to #rivendell in irc at freenode, look for zotz. If you would like to voice chat in a google hangout or via phone, let me know and we can work out details.
Do you know of a good dcp video (with audio) player for linux? I did some dcp work years ago in making a commercial for the station to run on local theatre screens, but I don't recall if I had a player or not available at the time. Can VLC do it yet, I just saw something saying it could not yet do audio and video at the same time. all the best, drew On Sat, Sep 5, 2020 at 12:39 PM Bill Putney <[email protected]> wrote: > Drew, > > Thanks, I'll take a look at it and see what I can make work. > > I've been doing content prep for the Port Townsend Film Festival and a > couple years ago we converted to Digital Cinema Package (DCP) for the whole > festival.
