Locate the Real Ball Release Before Studying the Trail

Start with ordinary-speed playback

Watch the player move into the shot and follow the ball rather than the graphic. Then pause near the point where hand and ball separate. Depending on frame rate and motion blur, the recording may show an interval around release rather than one perfectly sharp instant.

Compare adjacent frames

Move through a few frames before and after the suspected release. Look for a changing gap between hand and ball. Avoid selecting a frame simply because the trail first becomes obvious: a visual effect can start later than the original action. Keep the player and ball visible in the same view.

Do not extract unsupported measurements

Finding a release interval does not provide a calibrated angle, speed or repeatability score. Camera position, perspective and frame timing matter. Use this exercise to make your review more specific, then seek suitable measurement tools if numeric analysis is the goal.
