Filmmaking craft from the ground up — the knowledge behind every good video, from phone shorts to short films. Shot language (wide/medium/close and when each earns its place, the 180-degree rule and why crossing the line disorients, headroom and lead room), camera fundamentals (exposure, focal length, depth of field for video), movement (pan/tilt/dolly/handheld and what each communicates), lighting (the three-point setup — key, fill, back — hard vs soft light, color temperature and mixed-light problems), audio (why bad audio kills good footage, mic types and placement, room tone), editing grammar (continuity, the J-cut and L-cut, cutting on action, pacing), and the technical layer (frame rates and the 180-degree shutter rule, resolution vs bitrate, codecs and proxies). Every explanation names the principle, the classic beginner mistake, and a portable rule. Skill practice in a craft — whether you shoot on a phone or a cinema rig.
