Whiteboard talk

Turn my talking-head video into a whiteboard talk: a marker writes what I say as I say it, on paper pages cut in between my on-camera shots, and one simple diagram draws itself as I explain. Transcribe what I say and first cut out flubs, repeated takes and long pauses, cutting only in pauses of my speech. Work out the one idea I am explaining and the one picture that shows it. Cut between me on camera and full-frame pages made with the marker-page element, each cut hard and in a pause of my speech, with my voice playing on under the page, one or two pages in every 15 seconds, and end on me talking. Write every word I say in the notes of its shot, in the order I say it, so the writing is the captions: add no other caption track and write no word twice. A shot that carries on across a cut starts its earlier rows with ~. Keep rows short and big: at least 72 px on a page and 48 px as it shows on screen, whole inside the frame. Put the figure I land on in a large row of its own, in the marker colour. Add a mark only on what my voice names: a ring on the figure I land on, a strike on what I correct, on the word I correct it, an underline on the word I lean on, an arrow from one word to the word it leads to. Pick the diagram from what I say: web when everything connects to everything, or when I count pairs or links; bars when I compare numbers; none when neither fits, and then the words fill the page. Use only figures I give or that you can read in two sources. A diagram that carries over a cut starts drawn, with its At inputs below 0. On camera, set page to false on the marker-page clip. When a whiteboard shows in my footage, track_plane it and pin the clip to it with fit contain, aspect auto and blend multiply, at about twice the size you want on screen. A blank board tracks badly: if my camera does not move and the corners shake, hold them still with edit_track. Rotoscope anyone who passes in front of the board with track_occluders. When no board shows, put the ink on the plain side of the frame, never over my face, and set inkColour and shade so every word reads at 4.5:1. Give each on-camera shot a slow push toward my face, and punch in on a cut in the pause where I turn the argument. Make one quiet original music track that plays through the whole film under my voice, and add a soft pen scratch on the few strokes that matter: the big figure, a strike, the diagram. Keep my footage and my voice as they are. Marker look: Marker paper. Import the marker-page element, set look to marker-paper on every clip of it and bind its segments to my voice's transcript. Put the paper-texture element (kind paper) on a track above each page for the same time.
