Each age needs a different kind of coaching, and a different amount of video. These pages explain what is typical at each stage, what is worth coaching, and where a phone and TacticalSnap actually help.

Coaching U5 soccer: what the game looks like at three and four, and where video fits
U5 soccer is play, not games: short practices of 30 to 45 minutes, a ball for every child, 1v1 to 4v4 games without goalkeepers, and no scores that matter. Video is for the coach, not for the kids: a phone on a tripod shows you which games keep everyone moving and who barely touches the ball, so you can change next week's practice. Never post clips of U5 players publicly.
Coaching U10 soccer: 7v7, the first real tactics, and how to use game video
U10 soccer is usually 7v7, or 5v5 in some countries, on a small field with goalkeepers and rules that encourage playing out from the back. It is the best age to start using video: a few seconds of your own game show kids where the space was, and the coach sees patterns that are invisible from the sideline. Film from the midfield line, up high, with the whole field in frame, and show kids seconds, not minutes.
Coaching U15 soccer: 11v11 tactics, player development, and a weekly video routine
U15 soccer is the full game: 11v11 on a full or near-full field, offside, team systems, and players who can understand and use video. This is where analysis pays off most: team shape, pressing, transitions and set pieces can be shown on your own game, and players can review their own clips. Film from up high on the midfield line, keep a weekly review of 15 to 20 minutes, and make it about decisions, not blame.
