They will say it felt cheap, or they will disengage. The reason is physical rather than aesthetic. Your eye is tracking something: a face, a hand, a moving car. At a cut, if the thing you were tracking has jumped to a different part of the frame, or is now moving the other way, your eye has to find it again. That re-acquisition takes a fraction of a second, and during it the viewer is looking for the subject rather than watching the film.\n\nGood cutting is mostly the business of not making anyone do that.\n\n## Cut on the action\n\nThe most useful technique in editing, and the easiest to apply tonight. When a movement happens across two shots (someone stands up, opens a door, turns their head) do not cut before or after the movement. Cut in the middle of it, near the point of greatest motion.\n\nIn practice you overlap. Let the outgoing wide shot begin the door opening. Start the incoming close shot two or three frames *earlier* than where the wide left off, so the action repeats slightly. The eye is busy following the motion and the join disappears. If you cut cleanly at the exact same frame it often reads as a tiny stutter, because a real body decelerates and the second camera never quite matches.\n\nMatch the position too. If the door is on the right of frame in the wide, keep it right in the close. Editors call this matching the frame, and it is the difference between a cut you can watch fifty times and one that itches.\n\n## The line, and eyelines\n\nTwo people talk. Draw an imaginary line between them. Keep every camera on one side of that line and person A always looks screen-right, person B always looks screen-left, and the audience knows without thinking that they are looking at each other. Cross the line and both of them look the same direction, at the same wall, and the scene stops being a conversation.\n\nThis is the 180-degree rule and it is not a superstition; it is how screen direction encodes relationship. The same applies to travel: a character walking left to right who cuts to walking right to left reads as turning back.\n\nIf you were handed footage that crosses the line, you have three repairs: cut away to something neutral in between, use a shot taken *on* the line (straight down the middle, both people in profile or facing camera), or use a moving shot where the camera is visibly seen to cross.\n\n## J cuts and L cuts\n\nNamed for the shape they make in the timeline once you unlink audio from video.\n\n- **L cut**: the audio of the outgoing shot continues over the incoming picture. You cut to the listener while the speaker is still talking.\n- **J cut**: the audio of the incoming shot starts before its picture. You hear the next room, or the next line, a beat before you see it.\n\nBoth work for the same reason: the sound is continuous across the join, so the cut has nothing to announce itself with. A dialogue scene cut with hard, matched audio-and-picture cuts sounds like a slideshow. The same scene with two or three J and L cuts sounds like a film, and no viewer can tell you what changed.\n\nMechanically, find the link or linked-selection toggle in your editor's timeline, switch it off, and drag the audio edge past the video edge. Every editor mentioned in this course does it, including Kdenlive and Shotcut.\n\n## Jump cuts are a device, not an error\n\nClassically a jump cut is a mistake: same subject, similar framing, some time removed, so the person appears to teleport within the frame. The eye tracks a face and the face has moved without cause.\n\nIn talking-head and short-form video the convention flipped, and it flipped for a reason. When the audience already knows the speech has been compressed (every breath, \"um\" and false start removed) the jump is not read as a break in continuity. It is read as honesty about the compression. It works.\n\nIt stops working in two situations, and both are common. If the speaker moves a lot between cuts, the teleport is large and the eye complains. And a hundred jump cuts destroy any sense of place, because the space is never allowed to exist.\n\nThe cheap fix, and it is what professionals use: on every second or third jump, scale the incoming clip to about 110 to 115% and reframe slightly. Now the framing has changed enough to read as a different shot rather than a discontinuity in the same one. Alternate the punch-in with a cutaway and the sequence stops feeling like a machine gun.\n\n## Transitions\n\nA hard cut is right roughly nineteen times in twenty. A cross-dissolve means time has passed or we are moving to a different mental space, and it means only that. Everything else in the transitions bin (cubes, wipes, glitch presets, page peels) is a signal that a decision has not been made about what the cut is for. Use them when the piece is about that look, and not to smooth over a cut that does not work; a bad cut with a dissolve on it is a bad cut that now takes longer.\n\n## Today\n\nFind any two-person conversation you have shot or downloaded. Cut it hard, watch it, then move two audio edges to build one J cut and one L cut. That single change is the fastest visible improvement in this course."},"check":{"question":"A vlogger removes every pause from a piece to camera, producing forty jump cuts.
