What a camera can see in a squat snatch
A squat snatch travels from the floor to overhead in one pull and is received in a full overhead squat. The rubric measures the elbow angle in the finish frame and the knee angle at the deepest frame, so a rep that reaches depth with bent arms and one that locks out but stays high score differently rather than averaging into the same number. Side and oblique views support both. The identity gate also checks how far the wrists travelled: a small travel means the bar started overhead, which is an overhead squat.
How ScoreRep scores a squat snatch
The rubric declares 4 scored criteria. The strongest single camera angle is the left side view. Every criterion below is available from that angle.
The score is the points earned divided by the points the recorded angle could support, so a clip filmed from a limited angle is never quietly marked down for what the camera could not see. At least 60% of the applicable weight has to be measured before a result is ranked at all.
| Criterion | Points | Measured from the athlete’s pose | Full marks when |
|---|---|---|---|
| Overhead lockout | 30 | elbow angle in the finish position | 165° or more |
| Catch depth | 25 | knee angle at the bottom of the rep | 95° or less |
| Hip extension | 25 | largest hip angle in the rep | 172° or more |
| Explosiveness | 10 | time taken by the lifting phase | 0.8s or less |
Criteria that depend on the camera angle
These criteria are excluded, not estimated, when the recorded angle cannot support them. That is why the same set filmed twice from different positions can produce two valid scores out of two different totals.
- Catch depth — needs a left side, right side, left oblique and right oblique view.
- Hip extension — needs a left side, right side, left oblique and right oblique view.
Does this squat snatch rep count?
ScoreRep answers that in two separate steps. First, the clip has to read as a squat snatch at all: every check in the table below has to pass, and a reading the camera could not take counts as a fail, never as a pass. A clip that fails is returned unranked with the reason attached, rather than scored low against the wrong rubric, and no template can override a failed check.
Second, the scoring criteria award points. Falling short of a full-marks threshold costs points, not the rep. Every number here is read from version 2 of the squat snatch rubric, the same file the scoring engine runs.

- How the rep counter decides between a valid rep and a no-rep, station by station.
| Reading | Has to be | Otherwise rejected because |
|---|---|---|
| Vertical travel of the hips across the rep | 0.1 or more | neither the pull nor the receiving squat is clear |
| Smallest knee angle in the rep | 120° or less | the catch is not deep enough, which reads as a power snatch rather than a squat snatch |
| Whether the hands finish above the shoulders | yes | the bar is not overhead, so this does not read as a snatch |
| Elbow angle in the starting position | 130° or more | the elbows are racked at the start, which reads as a thruster rather than a snatch |
| Elbow angle in the finish position | 155° or more | the elbows are not locked out overhead |
| Vertical travel of the wrists across the rep | 0.2 or more | the bar did not travel from the floor to overhead, which reads as an overhead squat rather than a squat snatch |
What the recording has to contain
Eligibility decides whether a result can enter a leaderboard. Failing it does not block the feedback — the clip is still scored and returned, but marked unranked with the reason attached, so a bad camera position never silently becomes a bad score.
- A pose has to be detected in at least 55% of the frames.
- The camera angle has to be one of: left side, right side, left oblique and right oblique.
- At least 1 complete repetition has to be detected.
What is deliberately not scored
Identity, repetition counting, eligibility and the score are derived only from the athlete’s pose. Measurements that come from tracking an external object — the path of a barbell, for example — are drawn on the review overlay but are deliberately outside the scoring contract, so they never affect the number.
For this movement that applies to Bar path. It is listed in the rubric so the exclusion is visible rather than silent, and it earns no points.
Reading the result
This is a lift where the score and the outcome can disagree honestly. A rep can be caught, stood up and counted while scoring poorly on lockout, because the arms softened on the way down. That is worth knowing. Read the lockout criterion as a leading indicator across a session: it usually falls a set or two before reps start being missed outright.
A technique score is educational feedback about visible movement. It cannot tell you whether a load is safe for your joints, whether pain means something, or whether a programme suits you. Those judgements need a coach or clinician who knows your history.
