Because the viewer gets to choose nothing and still sees everything: the close-up when the voice cracks, the wide shot when you move, the side angle when the song turns. Two, three or four phones give you that. The only hard part has always been the editing — and that part no longer has to be done by hand.
Old phones work perfectly as extra cameras. They do not need to match: different phones, different starting times, different zoom.
Every phone records at the same time, from its own spot.
Film vertically if the video is for Reels, TikTok or Shorts. Let every camera record sound — that sound is what lines the cameras up afterwards.
With several cameras, the editing is where it usually falls apart: line up four clips, decide which angle wins every few seconds, and make sure every cut keeps the lips on the words. A three-minute song can take an evening.
camrip does that part: it syncs all the cameras by their sound, picks the best-looking shot for each cut — in focus, well exposed, well framed — and cuts on the beat. You get one vertical reel, and you can still move any cut yourself.
