I’m still in the stage of a beginner with shotcut.
I’m looking for a functionality, which really should be there, but I cannot find yet: I want to insert a video at some place in the timeline but DO NOT WANT to overwrite other videos in that area. Instead I want to have everything to the right of this site moved further to the right.
Or you can open the clip in the source viewer. Copy it (Ctrl + C). Place the play-head where you want the clip to b inserted in the time line then Paste (Ctrl V). The clip will be inserted at the play-head position and everything will be moved to the right.
