Video Diagnosis

Use video as a coaching tool rather than simply a replay. Different angles, slow motion and deliberate frame-by-frame review can reveal the first technical breakdown that was difficult to see at full speed.

Video should support coaching, not interrupt it. Capture only useful footage, follow programme safeguarding and content-permission procedures, and avoid turning every repetition into a filming exercise. The purpose is clearer technical feedback.

Coaching Tool

What Should Video Tell You?

Video should help answer a technical question you could not confidently answer in real time.

Coaches should know what they are looking for before repeatedly replaying a clip.

Review the whole movement before focusing on the visible mistake.

Slow motion is most useful when it exposes timing, position or sequencing that full-speed viewing hides.

Camera Position

Different Angles Answer Different Questions

Front

Symmetry

Useful for left-right alignment, spacing, leg positions, shoulder levels and group synchronisation.

Side

Shape & Travel

Useful for body lines, forward-backward travel, set angle and vertical alignment.

Diagonal

Combined Context

Useful when both depth and left-right movement need to be seen.

Wide

Team Picture

Useful for timing, formations, synchronisation and differences between groups.

Review Method

Watch It Three Ways

1 · Full Speed

Understand the Skill

Watch once without stopping. Identify the overall outcome, rhythm and obvious symptom.

2 · Slow Motion

Find the First Change

Look for the earliest frame where the movement stops matching the intended pathway.

3 · Full Speed Again

Confirm Relevance

Make sure the tiny detail seen in slow motion actually matters to the full skill.

Coaching Quality

Useful Video Review vs Poor Video Review

✓ Useful Review

Starts with a clear coaching question.
Uses an angle that can answer it.
Watches the full movement first.
Looks for the first breakdown.
Uses slow motion selectively.
Compares repetitions where useful.
Identifies one priority correction.
Retests after coaching.

✕ Poor Review

Records everything without a purpose.
Uses an angle that hides the problem.
Only rewatches the final fall.
Pauses on irrelevant frames.
Finds ten faults at once.
Shows the athlete a clip without explanation.
Never retests the correction.
Lets filming interrupt the session.

Coach Thinking

Questions Before You Replay Again

What am I trying to confirm? Do not watch without a purpose.

Can this camera angle actually show it? A side-view problem cannot always be diagnosed from the front.

What changed first? Avoid jumping straight to the final failure.

Does the same fault happen every time? One unusual repetition may not represent the athlete's normal technique.

Is the error technical or timing based? Position may be correct but arriving too early or too late.

What correction can the athlete actually use now? Translate analysis into simple coaching language.

Example Use

Which View Helps Most?

Problem	Useful View	Look For	Coach Question
Back handspring travels sideways	Front / rear	Hand placement and shoulder line	Where does left-right deviation begin?
Back handspring lands short	Side	Set, shoulder angle and block	Does the athlete create enough backward travel?
Prep consistently leans forward	Side	Load position and foot platform	Is the lean present before the stunt rises?
Multiple stunt groups hit at different times	Wide front	Dip and rise count	Which group moves first?
Toe touches look uneven	Front	Leg height, hip rotation and timing	Is one leg lower or simply later?
Turn repeatedly travels	Front + side	Supporting foot and centre	At what point does the body leave the vertical axis?
