Right, but what if I just shared a script? You start with a digital copy of the movie I'm starting from... I extract the audio... And then my script downloads the Public Domain movies... ...and I've got a hard-coded list of cuts to take from each of the Public Domain movies... ...and combine it with the movie audio? My script is just a few hundred KB. As long as the movie you start from is pretty well in audio synch with the version I start from... Heck, I could probably even compensate for that, too... A little bit of analysis to listen for the first words spoken...
