Me too please! We are filming important traditional presentations (show and tell by old people) with three cameras and several digital audio-recorders.
We could make our work-flow so much more efficient, if we could just keyboard-nudge our clips or the audio-clips directly in Shotcut, and then possibly time-lock certain items (two video-clips and one audio-clip) together, so they would move together. Seen it in Lightworks and they have key-nudge - but their zoom is useless so I never get to see what I am doing.
So far we are using a method (found online) where we analyse the offsets in Audacity, then crop the master-audio to fit one “master” video and assemble those two in Avidemux. And then come to Shotcut “to make it all pretty”… and add more camera angles for details (hands weaving something or whatever).
