Edit your video by editing its transcript
InClipp is a video editor for YouTubers. It writes down what you say, and the transcript is your timeline: delete a word from the text and it is cut from the video; choose a phrase and give it a title, a callout or a zoom that plays exactly while it is spoken. Everything runs on your Mac.
Free. Exports over 90 seconds need a licence: $59 a year, 3 computers.
